Collaborative Learning and Peer-tutoring in Mathematics Kathryn Joy Rowe A thesis presented in partial fulfilment of requirements for Master of Educational Studies (Mathematics) Massey University 2002 ii Abstract This study sought to promote learning by enhancing the level of higher order cognitive talk among collaborative groups engaged on mathematical tasks. An intervention, designed to utilise structures such as listening, multiple retelling, questioning, elaboration, and justification to promote high-level discourse, was trialled and refined using an action research classroom study. The collaborative skills training programme was based on Medcalfs peer-tutoring model (1997) and adapted to incorporate features of Lyman's Think-Pair-Share collaborative model (1992). The teacher' s role was seen as crucial to the development of collaborative group practices which establish the structures for high-level discourse. Collaborative group practices were reinforced in follow-up class discussions where the teacher facilitated student reflection on the mathematical strategies and the collaborative group strategies. It was also seen as important for the teacher to select appropriately levelled tasks which maintained the learner in his/her Zone of Proximal Development. Findings indicated that the structured intervention enhanced the level of higher order discourse between students and that it was an effective procedure to mediate learning. Several patterns of discourse were also identified that could provide useful indicators of higher level discourse to teachers during daily classroom observations. iii Acknowledgements I would like to extend heart-felt thanks to my supervisors Dr. Glenda Anthony and Brenda Bicknell at Massey University for their direction, critique and encouragement.

Introduction "Cognito, ergo sum" - Descartes 1.1 Background The end of the twentieth century was characterised by the development of computer technology enabling vast quantities of information to be readily accessed by the world population. The information explosion will continue to expand ... Increasingly we will move away from defining educational success in terms of the quantity of information mastered. Instead, to a large extent, we will define educational success as the ability among students to generate, question, combine, categorise, re- categorise, evaluate, and apply information. Secondary will be the content of the information; primary will be thinking skills- thus, the need for thinking skills structures in our classrooms. (Kagan, 1994, p. 111) As a response to the global ' information highway' and changing work-place structures, the Ministry of Education developed the New Zealand Curriculum Framework (Ministry of Education, 1993) that identified eight generic essential skills: physical skills, self­ management and competitive skills, communication skills, problem-solving skills, social and co-operative skills, information skills, numeracy skills, and work and study skills. Curriculum documents were revised during the 1990s to apply the New Zealand Curriculum Framework's essential skills to particular curriculum contexts. The first of these revised curriculum documents was Mathematics in the New Zealand Curriculum (Ministry of Education, 1992). This separated the mathematics curriculum into six key strands: 8 • • • • • • mathematical processes, number, measurement, geometry, algebra, and statistics . This core document and supporting documents such as Implementing Mathematical Processes (Ministry of Education, 1995) and Development Band Mathematics (Ministry of Education, 1996) were also influenced by the international mathematics community's emphasis on mathematical problem-solving which had arisen during the 1980s in the United Kingdom with the Cockcroft Report ( 1982) and the Agenda for Action Report in the United States ( 1980) and recognition of the importance of discourse and the value of collaborative learning practices in mathematics (National Council of the Teachers of Mathematics, 1989). For example, the Implementing Mathematical Processes document explicitly linked the need for 'new essential skills' with mathematical processes: The abUities- to think flexibly, be adaptable, be a creative problem solver, and be able to communicate and work co-operatively- have been highlighLed as essential skills for life in the world tomorrow. Mathematics teaching can play an important part in equipping our students with Lhese fundamental skills. This is one of the reasons why the mathematics curriculum emphasises the importance of developing the students' abilities to reason, think flexibly, communicate, solve problems and collaborate in a mathematical context. (Ministry of Education, 1995, p. 7) Mathematics in the New Zealand Curriculum required teachers to "design courses to provide their students with mathematical experiences which will enable the students to 9 achieve the broader aims and achievement objectives for the curriculum" (Ministry of Education, 1992, p. 18). This included developing courses to emphasise the essential skills of logic and reasoning, communicating ideas, problem-solving and collaborative group work. The processes of logic and reasorung and problem-solving were readily accepted by mathematics teachers as integral to mathematics learning (Holton, Anderson, & Thomas, 1996). From the era of Platonic deduction and proofs mathematical thinking has emphasised logic and reasoning. Moreover, many of the established traits of effective thinkers-with cross-disciplinary characteristics of persistence, creativity, questioning, precision, metacognition, flexibility, listening, and the ability to restrain impulsiveness (Costa & O'Leary, 1989}-parallel those traits of good problem-solvers within Mathematics in the New Zealand Curriculum , namely flexibility, creativity, the ability to reflect, experiment, improve, and use divergent and convergent approaches. Parallel to the focus on processes the Mathematics in the New Zealand Curriculum encouraged New Zealand teachers to change their instructional practice of transmitting specific content in mathematics to interpreting and implementing mathematics through the essential skills base. This social constructivist approach suggested that classroom practices support students' development of mathematical understanding through social interaction involving conjecture, dialogue and critical examination. While teacher-to-learner transmission of information, facts and ideas retains a place in learning, it is only when we test, confirm, assimilate and accommodate ideas into our conceptual frameworks that knowledge takes on meaning (Hill, 1992). 10 The new expectation within the socio-constructivist approach was that individuals would develop better mathematical thinking through discussions with peers when they gave more coherent explanations, responded to questions and challenges, listened to and made sense of others' explanations, and asked for clarification of ideas. The use of such conceptually orientated explanations, involving alternative solution strategies, assists in building relationships between forms of representation strengthening the students' mathematical achievement (Fuchs, Fuchs, Karns, Hamlett, Dutka, & Katzaroff, 1996). Based on :findings from collaborative research, Cobb and Wood (1990) contend that when children engage in this type of mathematical 'talk', it can result in "learning opportunities that rarely arise in traditional instructional settings" (p. 34). Students learn to reason analytically and to communicate by explaining and justifying their mathematical ideas (Wood, 1999). 1.2 Teaching Reforms and Collaborative Learning The effective use of mathematical talk to foster learning in collaborative groups required teachers' perceptions of their role to change whereby they became facilitators of learning (Von Glaserfeld, 1990, cited in Mayers & Britt, 1995) and in the 1990s teachers were seen to implement collaborative group work in the mathematics classroom in a range of ways (Thomas, 1994b) from putting students in groups and expecting them to work together, to a formal structured collaborative model with specific group and learning outcomes. Junior classrooms which used a Beginning School Mathematics (1993) model often had groups of children collectively engaged on activities that were designed to consolidate a core concept that had been introduced by the teacher. Examples of children using co- operative/collaborative practices in later primary years included working in groups to 11 complete a one-off investigation or discussing a solution with a peer simply because of their physical proximity rather than because of collaborative engagement on a mutual task (Medcalf, 1995). Thomas' study (1994a) into discourse in the New Zealand junior mathematics classroom noted that though most talk was task-related, more was related to the social aspects than the cognitive aspects of the task. The challenge then was to consider and develop processes that would encourage ' learning enhancing' discourse. Thomas found that the social and cognitive nature of the task impacted significantly on the kind of talk which occurred and that problem-solving tasks were more likely to engage the children in explanations and abstract discussion compared to games or production tasks (making a model or collecting data). In order to reduce the social talk associated with organization within the groups most groups were reduced to pairs. Thomas also suggested that the ability to engage in collaborative abstract thought may be maturational and that "children in the first two years of school are not able to engage in substantial 'abstract' talk with their peers" (Thomas, 1994b, p. 327). While the intention of Mathematics in the New Zealand Curriculum (1992) was to support improved learning outcomes utilising the social-constructivist approach to learning including cooperative group contexts, two international studies in mathematics achievement appeared to provide evidence to the contrary. The duel studies-the Third International Mathematics and Science Study (1994) and the Third International Mathematics and Science Study - Repeat (1998), showed no significant improvements in mathematics achievement by New Zealand students. A recent Education Review Office (ERO) report 12 (2000) criticised the curriculum documents and queried "whether or not the structure and content of the curriculum documents provide a clear and practical guide for teachers, especially those who are not educated specialists in mathematics" (p. 104). The prevalence and effectiveness of teaching and learning in the New Zealand classroom by using small [co­ operative/ collaborative] groups was questioned when other countries which seldom used small groups achieved more highly: Inside the classroom, New Zealand primary school teachers typically use small group organization for teaching and learning mathematics. This assumes that students will learn better if they are taught in small groups for part of the time and then left to work individually or with groups not directly supervised by the teacher. (Education Review Office, 2000, p. 101) The Education Review Office report urged for a closer examination of small group teaching practices in New Zealand claiming that, " it is not self-evident, for instance, that the conventional New Zealand method is necessarily more child-centred, especially where it is the more or less exclusive arrangement" (p. 101 ). Specifically, ERO suggests we need further research information on group teaching "in terms of its contribution to developing mathematical understanding. This despite widespread claims as to its effectiveness, and the complexity of the process for teachers" (p. 101 ). Increasing research on teaching strategies and disseminating the findings of effective practice gives teachers better information on which to base their decisions. The thesis contributes to the body of research investigating group learning practices by investigating the use of specific discourse structures to enhance the level of higher order cognitive talk within the context of collaborative groups in the mathematics classroom. 13 1.3 Definition of Terms Definition of the terms associated with group learning practices are complex and often interpreted differently in different education settings intemationally--by teachers, researchers and policy makers. For the purposes of this research, the following definitisll$_ are provided as starting positions to guide the reader. A fuller discussion of their origin in relation to literature is provided in Chapter 2. • Collaborative learning is structured and organised small group work designed to actively engage students in ''the learning process through inquiry and discussion with their peers" (Davidson & Worsham, 1992). • Peer-tutoring is a form of co-operative learning in which students are trained to use specific instructional strategies to promote the learning of peers (Medcalf, 1992) 1.4 Research Questions The aim of the study was to implement and investigate the effectiveness of a collaborative skills programme. The intervention programme was designed to increase students' 'learning enhancing' discourse, that is, to increase the amount of cognitive talk students engaged in while working in collaborative groups. Using an action research framework, information gathered from students' conversations as they worked in collaborative groups, anecdotal observations from their teachers, students' questionnaire responses and a diagnostic test formed the basis of subsequent modifications to the intervention. The following questions were investigated in the main study to evaluate the effectiveness of adaptations made to the structure of the programme and to examine resulting discourse patterns seen in the pilot study: 14 1. Does participation in the programme increase the frequency of 'higher order' cognitive interactions between children in the mathematics classroom? 2. Are there 'oral flags' which identify higher order cognitive thinking? The collaborative skills programme was designed to be a practical classroom intervention which promoted peer scaffolding as an effective support for academic gains in mathematics. Effectiveness was addressed in relation to both teachers' and students' perceptions about the programme and through achievement gains in the Numeracy Development Project (Ministry of Education, 2002): 3. How did the students think that participation in the programme affected their academic or perceived academic achievement? 4. What changes did the teacher notice in individual/class interactions or attitudes when mathematical problem-solving? 1.5 Overview Chapter 2 provides a theoretical framework for the role of discourse in learning and a rationale for the inclusion of specific techniques in the collaborative training programme. This is supported by a review of literature from America, Europe, Australia, and New Zealand, including discussion and evaluation of peer-tutoring and collaborative learning programmes. Chapter 3 describes the action research methodology. This includes a description of the pilot study and the results which led to modifications of the collaborative training programme for the main study. The data collection and analysis processes are described. 15 Chapter 4 presents and summarises the data collected for the results from the transcriptions, the teachers' anecdotal comments, the students' questionnaires, and the academic data recorded from the diagnostic interviews. In Chapter 5 the key findings related to the research questions are discussed along with the limitations of the study and concluding thoughts. Questions are raised for consideration in future research. 16 Chapter 2 Literature Review 2.1 Introduction The literature review is divided into three sections. The first section considers the role of discourse within a social constructivist theory of learning whereby interactions are seen to promote learning by bringing about changes in the cognitive structures of those engaged in the interaction. The discussion of the socio-constructivist approach to teaching and learning, which underpins the current New Zealand mathematics curriculum, will include consideration of two theories of foundational relevance: Vygotsky's social learning theory (1978) and Piaget's developmental theory (1962). The second section reviews peer-directed programmes and research studies which structure students' interactions to promote their engagement in higher order discourse and thinking. The section focuses on peer-tutoring and cooperative/collaborative learning models, and highlights specific structures which enhance mathematical skills in reasoning and thinking, problem-solving, and communication-all of which are key process strands in New Zealand and overseas mathematics curricula documents. Though the role of discourse in the home influences thinking skills, for the purposes of this project the review will be confined to research which has occurred in the classroom. The third section investigates tools for the analysis of discourse in the classroom and provides a background and rationale for the inclusion and modification of the analysis tool used in this project. 17 2.2 Learning Theories and Discourse Within the socio-constructivist approach to learning, the process of learning is seen as the active construction of knowledge within a social community (Simon & Schiller, 1991, p. 130). According to this approach learning is a by-product of interaction. Discussing new ideas with others transforms how we think about the ideas. Accordingly the process of accommodation: Allows us to organise and reconstruct the new material for ourselves and integrate it into our existing knowledge base, thereby allowing us to understand and remember it better... During such interaction with another, we clarify ideas, negotiate meaning, develop new skills, and construct new knowledge. (King, 1997, p. 221) Therefore although "thinking is the personal process individuals use to create their own understanding" co-operative exchanges are seen as extremely beneficial because the resulting "shared visions and understandings enlarge the process spheres that individuals may explore, thus making enhancement of individual thought as boundless as the visions shared" (Davidson & Worsham, 1992, p. xx). The socio-constructivist theory of learning, and its promotion of the role of discourse, is underpinned by two major theorists' work: Piaget's cognitive developmental approach to learning (1967) and Vygotsky's social learning theory (1978). 2.2.1 Individual Development of Thought Piaget (1967) believed that learning was acquired through the process of assimilation where the ideas or concepts, which he termed schemata, were developed in response to stimuli. Subsequent information or stimulus allowed for the development of a schema through a 18 process called accommodation. If new information compared favourably with existing schema it was accommodated into the schema, enlarging its cognitive reference. If the incoming stimulus compared unfavourably it was rejected, or a period of disequilibrium resulted while the individual searched for more information causing the reorganisation and reconceptualisation of the schema. Within this theory, discourse facilitates the exposure of one individual's schemata or concepts causing individuals to clarify, develop, expand and elaborate their thinking in defence of their particular schemata. Piaget's theory favours a classical psychological approach to the measurement of the child' s cognitive development. The child's independent activity and achievements are observed, passing through cognitive stages of maturity using stimuli that progress from concrete to semi-concrete to abstract. The first stage, is that of the sensorimotor period, (approximately 0-2 years) where the child responds from reflex action, then to the preoperational stage (2-7 years) with increasing imitation and experimentation, to the concrete operational stage (7-11 years), and then to the formal operational stage where the individual is able to visualise actions abstractly and perform them without physical experimentation. According to this cognitive theory a child's mathematical cognitive development progresses from intuition to formal operations, from exploration through play to structured games, to representation through pictures and symbols and then formal operations, from a social experience of number to the learned abstractions and formal practices of mathematics. As such, cognitive development is influenced by the child's physical and maturational ability to imitate. It begins as a 'tentative exploratory activity' (Dienes, 1959) initially determined largely by spatial experiences. With maturity the development of language takes on an 19 increasing role; "physical actions become internalised and generalised into concepts and relations to which may be attached, either words or mathematical symbols" (Dickson, Brown & Gibson, 1984, p. 12). For children, their schemata are qualitatively different to that of adults and commonly include partial understandings or misinterpretations. The development of their schemata is influenced by the linguistic and cognitive practices in their environment and are adjusted using an egocentric logic with subsequent experiences and social interactions. Thus in learning mathematics, individuals construct ideas, processes and unique understandings for themselves. 2.2.2 Social Development of Thought In contrast to Piaget's cognitive developmental theory where the independent activities of the child are measured, Vygotsky (1978) emphasises the social aspects oflearning, claiming that each child has a higher level of cognitive development evidenced by his/her ability to imitate. In this way, Vygotsky focuses on the cognitive processes, which are still evolving, not those already mastered: "What the child can do in co-operation today he can do alone tomorrow" (Vygotsky, 1962, p. 104). Vygotsky's sociohistorical-cultural psychological theory of learning contends that the combination of speech and practical activity support the most significant intellectual development (Blanck, 1990). Vygotsky claims that because children's higher mental functions originate in the activities and social dialogues in which they participate, those children involved in collective discourse, verbal and non-verbal are able to develop their thinking more effectively compared to children who are alone. However, Vygotsky 20 qualifies the nature of social interactions claiming that a child can imitate only that which is within his/her developmental level or Zone of Proximal Development (ZPD}--the "distance between the actual development level as determined by the independent problem-solving and the level of potential development as determined through problem-solving under adult guidance or in collaboration with more capable peers" (Vygotsky, 1978, p. 86). Thus, within the education context students need to be provided with experiences within their ZPD, just above their level of independent functioning, so that cognitive processes are developed. In order to keep the students in their ZPD the task and the environment must be appropriately structured so that the demands on the students are appropriately challenging. The amount of intervention provided by the adult or more capable peer needs to be adjusted in response to the students' needs (Tharp & Gallimore, 1988, cited in Berk & Winster, 1995). Effective scaffolding occurs when: The tutor or the aiding peer serves the learner as a vicarious form of consciousness until such a time as the learner is able to master his own action through his own consciousness and control. When the child achieves that conscious control over a new function or conceptual system then he is able to use it as a tool ... the tutor in effect performs the critical function of scaffolding. (Bruner, 1985, p.215) Discourse facilitates "the collaboration necessary between expert and novice to acquire the cognitive strategy" (Palinscar, 1986, p. 95). Without the use of scaffolding Gallimore claims that children will learn at a less than optimum rate (Gallimore, cited in Holton, Anderson & Thomas, 1996). 21 2.3 Structuring Discourse in the Classroom 2.3.1 Teachers and Students as a Mathematical Community. The socio-constructivist approach to teaching and learning highlights the importance of providing social situations that allow children to construct and modify their mathematical knowledge through discourse (Yackel, Cobb, & Wood, 1991): To understand what they learn, they must enact for themselves verbs that permeate the mathematics curriculum: "examine ", "represent '', transform ", "solve ", "apply '', "prove ", "communicate ". This happens most readily when students work in groups, engage in discussions, make presentations, and in other ways take charge of their own learning. (National Research Council, 1989, p. 58, 59) Reform instruction advocates that teachers and students within the classroom setting form a mathematical community in which they construct ''their own knowledge individually and collectively, negotiating shared understandings and developing collaborative processes for validating ideas" (Neyland, 1994, p. 4). The teacher has a vital role as the expert who guides, models and interacts with students to provoke them to think mathematically, providing opportunities for students to verbalise their questions, explanations and strategies (Ministry of Education, 2002a). A teacher can be thought of as: A discourse guide and each classroom as a discourse village, a small language outpost from which roads lead to larger communities of educated discourse... Teachers are expected to help their students develop ways of talking, writing and thinking which will enable them to travel on wider intellectual journeys. (Mercer, 1995, p. 83) Peer discussions are seen as valuable not only if they lead to the correct answer but also because of the way they influence students' mathematical behaviour. The way students 22 think about and solve problems is 'influenced by discussions in which ideas are shared, challenged, and justi£ed' and is 'related positively to mathematics achievement' (Muth, 1997, p. 72). In particular co-operative learning puts students "in situations where they learn that reading, writing, listening and speaking in a co-operative manner are all-important components of successful problem-solving" (Muth, 1997, p. 72). Co-operative learning has many other advantages for supporting effective learning practices: Students learn mathematical language from each other and are also able to learn, firsthand, the various problem-solving strategies that their peers use. Equally important, students learn that there are usually different ways to solve a problem. Finally, co-operative learning builds leadership, decision-making, and conflict management skills, and ideally, positive attitudes towards mathematics. (Muth, 1997, p. 72) Within the mathematics classroom the mam source of scaffolding is the teacher. The teacher' s scaffolding role is most commonly evidenced in classroom discourse when the teacher focuses, extends, clari£es and redirects the learner (Carnboume, 1988). Using an appropriate selection of tasks or problems the teacher builds on prior knowledge and maintains the student within the Zone of Proximal Development Another aspect of scaffolding by the teacher is the appropriate selection of tasks or problems to maintain the students within their ZPD (Diezmann, 1998). Stein, Grover, and Henningsen (1996) investigated the selection of mathematical tasks by teachers and concluded that appropriate task selection included having appropriate amounts of time to engage on the task. Inappropriate time limitations precipitated low-order recall. Sustained pressure for explanations and elaboration was important through successive multiple presentations of solutions and justi£cations to the wider group or class as this encouraged 23 the making of connections and hence higher order thinking. 2.3.2 Authority Relationships and interactions within the classroom produce the construction of mathematical knowledge and identity, and are greatly influenced by the teacher's practices which establish social norms. Productive discourse practices in a classroom mathematical community not only support students' mathematical understandings but also give authority to their discourse, and value student authorship (Klein, 2002). The social goal in negotiating meaning is to resolve uncertainty and that in order to reach resolution students will appeal to the dominant authority. Prior experience, empirical evidence, a knowledgeable person or a text can represent this dominant authority (Clark & Helme, 1997). Brown (1994, cited in Brown & Renshaw, 1999) describes the process of 'Collective Argumentation' in which "authority is attained through discourse practices that privilege socio-mathematical norms such as meaningfulness, communicability and testability" (p. 114). In the absence of appropriate authorities students find it difficult to make metacognitive judgements about errors, anomalous results and the appropriateness of their problem solving strategies (Clarke & Helme, 1997). The teacher's role in the process oflearning to resolve uncertainty is important. If an autocratic teacher makes the majority of learning and organisational decisions in the classroom then students learn to rely on the teacher as their source of authority and to rescue them from uncertainty (Hill & Hill, 1990; Neyland, 1994). This can result in students developing poor decision making skills and exhibiting an unwillingness to attempt novel strategies or be open to other available authorities such as experience, empirical evidence, texts or knowledgeable group members (Davidson, 1985). 24 Teachers who consistently intervene when students are struggling take away their opportunities to make progress on their own (Stein, Grover, & Henningsen, 1996). Equally, a teacher who takes a laissez-faire approach and leaves the children to take responsibility for their own learning "does not provide for responsibility, cohesiveness, cooperative skills or academic achievement" (Hill & Hill, 1990, p. 18). In contrast, teachers who promote the model of positive interdependence required in collaborative learning and encourage an acceptance of peers' ideas which are presented with logic and evidence, support cognitive development, and the movement of children's beliefs from a position of dualism to ethical beliefs (Davidson, 1985). Perry (1970, cited in Davidson, 1985) describes students' beliefs about authority as cognitively developmental. At the initial level of development, Perry says students believe that all answers are right or wrong, and that only authority figures such as the teacher possess knowledge and answers. The next level of development shows students accepting some peers' viewpoints and becoming less dependent on texts or the teacher as the authority. In the later stages of cognitive development the students are able to value the opinions of others when these opinions are presented logically and with evidence. The students in this stage are also able to reason in a wider range of contexts and treat their teacher as a fellow learner rather than a person of authority. The teacher's pedagogy (beliefs and practices) influences the learner's sense of authority. Klein (2002) argues that the teacher can foster the learner's ability to apply constructed mathematical knowledge in new contexts by celebrating ''the student's presence and ways of making sense of mathematics and experience" (p. 391) and by giving them space " to 25 establish themselves in powerful ways in learning/teaching interactions as they construct mathematical ideas" (p. 392). Discourse moulds not only the content knowledge but also the learner' s mathematical identity and perception of his/her competence as students learn its linguistic code and how to relate to a subject (Blackredge & Hunt, 1985). The learner develops a sense of power through his/her legitimate use of mathematical ideas and practices, and hence a sense of internal authority. For the learner to develop this power they must be "capable of, respected and valued in, speaking/writing the accepted ' truths ' of a discourse, in enacting established ways 'of being ' and in going beyond these to forge something new" (Davies, 1991 , cited in Klein, 2002, p. 391). Teachers consider the relationships within discourse; of what is spoken and who it is spoken by, the power of the speaker's social relationship or authority to develop socio norms within the mathematics classroom (Klein, 2002). 2.3.3 Transparency One of the concerns for designing an intervention to enhance the level of higher order cognitive peer interactions is the degree to which the interaction amongst learners is structured. A balance needs to be achieved to enable the structure to promote both the exchange and challenging of ideas, and the freedom to pursue and develop individual thoughts (Cohen, 1994). The teacher has a major role in framing the language practices of the classroom as she acts as a translator for mathematical discourse "to help frame discussion, to pose questions, to suggest real life connections, to probe arguments, and to ask for evidence" (Adler, 1999, p. 51), and hence scaffold students' participation and provide access to school mathematics. 26 Adler (1999) warns that too much focus on the practice of mathematics discussion makes the discussion become the "main object of attention instead of a means to the mathematics" (p. 50). The discourse practices should be used as learning tools. Discourse as a social tool has a quality Lave and Wenger have labelled transparency (1991, cited in Adler, 1999). They describe transparency metaphorically as a window involving a complex interplay of visible and invisible characteristics: A window's invisibility is what makes it a window. It is an object through which the outside world becomes visible. However, set in a wall, the window is simultaneously highly visible. In other words, that one can see through it is precisely what makes it highly visible.... [Windows are like] 'mediating technologies ' in a practice ... [that] need to be visible so they can be noticed and used, and they need to be simultaneously invisible so that attention is focussed on the subject matter, the object of the attention in the practice. (Lave & Wenger, 1991, cited in Adler, 1999, p. 50) The discourse strategies for this project were developed with transparency in mind and aimed to enhance cognitive mathematical learning. The students were made aware of the significance of their talk to learning, and their teacher and the researcher modelled specific kinds of mathematical discourse to them. They were encouraged to model the same practices within collaborative groups and engage the strategies as a successful method of learning the mathematics. 27 2.4 Collaborative Learning The process of scaffolding can occur informally, or formally through the provision of structured co-operative and collaborative programmes that utilise discourse to enhance the teaching and learning of mathematics, enabling peers to construct robust knowledge structures as they clarify information and resolve discrepancies. Collaborative learning and peer-tutoring techniques provide scaffolding in the form of a peer who has authority because of their role (as tutor), their knowledge, or that they have the strategies to be able to utilise experience, evidence and texts in various combinations to provide authority. Most New Zealand classroom teachers utilise peer discussion as a fonn of scaffolding (Ministry of Education, 1997) as peers negotiate meanings and ideas while involved in shared tasks. However, the enhancement of achievement through peer scaffolding is more complex than assigning children to a group to work together to solve a problem (Peter­ Koop, 2002; Webb, 1989). Brown and Thomson (2000) make a finn distinction between what they call ' traditional group work' and learning together co-operatively to produce social or academic outcomes: Working round a table on individual tasks with the opportunity for discussion is not co-operative learning. Nor is having a team discussion, where some students can dominate or "hitch-hike". The core notion of co-operative learning is that when we co-operate, we work together to accomplish shared goals ... . While it helps to foster and develop interpersonal skills, co-operative learning is not a social skills programme. Rather it is an academic skills programme, a thinking skills approach that requires students to develop the necessary interpersonal and small group skills to enable them to work successfully together. (Brown & Thomson, 2000, p. 38) 28 Cooperatively styled programmes that have an active, focused approach to learning where both the teacher and the student are aware of the importance of scaffolded practice are more likely to lead to more effective learning (Brown & Thomson, 2000, p. 26). There is a wealth of methods currently employed in the classroom to promote collaborative learning. They build on the momentum of the cooperative programme development of the 1970s and group learning methods such as Constructive Controversy (Johnson & Johnson, 1987), Team Games (DeVries & Edwards, 1974), Group Investigation (Sharan & Sharan, 1976), Jigsaw Procedure (Aronson, Blaney, Stephan, Sikes & Snapp, 1978) and Student Teams Achievement (Slavin, 1989, 1996). Work has continued into the 1980s and 90s with Cohen's Complex Instruction approach (1986), Kagan's structural PIES approach (1994), Brubacher, Payne and Rickett's collaborative approach (1990) and Brown's Collective Argumentation (1994, cited in Brown & Renshaw, 1999). Johnson and Johnson define co-operative learning as "the instructional use of small groups so that students work together to maximise their own and other' s learning" (1994, p. 1). However, literature shows that others employ the term 'co-operative learning' in a loose fashion to include all group work. To avoid this ambiguity there has been a move by researchers in mathematics education to differentiate organised and structured group learning under the term 'collaborative learning' . Goos (2000) describes collaborative learning as those procedures "designed to engage students actively in the learning process through inquiry and discussion with their peers in small groups" (p. 39). It is a reciprocal process of mutuality where each other's reasoning and viewpoints are explored in order to construct a shared understanding of the task (Goos, 2000). 29 Davidson and Worsham (1992, p. xiii) identify four common attributes for all collaborative learning with the premise that the group work is organised and structured ''to promote the participation and learning of all the group": 1. There is student-to-student interaction in small groups. 2. There is individual responsibility and accountability, or positive interdependence. 3. There is structured cooperation. 4. A learning task/activity is selected for group work. In the definitions of both Brown and Thomson (2000) and Johnson and Johnson (1994) the term 'co-operative learning' could be interchanged for 'collaborative learning' but to avoid confusion with other models of co-operative learning the term collaborative learning will be used in this study. While references will be made to co-operative learning research which conforms to the collaborative learning definition the study specifically differentiates collaborative learning, which involves the development of cognitive thinking through verbal negotiations of meaning with their peers, from that of involvement in cooperative group tasks. Cooperative group tasks are considered shared activities whereas collaborative learning is "a mutual task in which partners work together to produce something that neither could have produced alone" (Forman & Cazden, 1985, cited in Thomas, 1994, p. 25). Working collaboratively in mathematics supports students' learning when they resolve contradictions that arise and when: ... They attempt to make sense of a situation in terms of their current concepts and procedures, accounting for a surprise outcome (particularly when two alternative procedures lead to the same result), verbalising their mathematical I - I 30 thinking, explaining or justifj;ing a solution, resolving conflicting points of view, developing a framework that accommodates alternative solution methods, and formulating an explanation to clarifo another child's solution attempt. (Yackel, Cobb & Wood, 1991, p. 394) Proponents of collaborative leaming argue strongly that effective collaborative leaming is not automatic. Students do not osmotically obtain effective leaming strategies but rather they "gain them by exposure to capable models and from guided practice in their use" (Brown & Thomson, 2000, p. 33). This includes leaming how to deal with disagreements, as collaborative leaming is not about harmonising, as it often involves intellectual conflict (Hill & Hill, 1990). If students do not develop skills of positive interdependence whereby they work together to achieve the group's leaming goals through the synthesis of independent and collaborative contributions their leaming is likely to be no more successful than competitive or individualistic learning models (Kneip & Grossman, 1979; Qin, Johnson, & Johnson, 1995). 2.4.1 Cooperative Model (Brown & Thomson, 2000; Johnson & Johnson, 1987) Brown and Thomson (2000) are two researchers in Special Education who have contributed strongly to New Zealand work on co-operative leaming and who differentiate it from traditional group work. They build on the extensive work of Roger Johnson and David Johnson who pioneered co-operative leaming as a teaching procedure (Johnson & Johnson, 1994; Johnson, Johnson & Johnson-Holubec, 1993; Johnson, Johnson & Stanne, 2000: Johnson, Johnson & Zaidman, 1985; Yager, Johnson & Johnson, 1985). According to Brown and Thomson's model (2000), as students practise collaborative learning skills they move through four levels of functioning. These levels of functioning are 31 based on Johnson and Johnson's '4Fs': forming, functioning, formulating, and fermenting. 'Forming' skills are basic skills required for groups to function such as moving and talking quietly, using eye contact and group members' names, and encouraging all group members to participate. 'Functioning' skills are those skills, which allow greater self-management within the group. Individual members maintain their given roles, all group members are included and encouraged, and the interactions are both courteous and positive. The next two levels of skills require more understanding of the task and the use of higher order thinking skills (Bloom, 1956). The third level of skills is 'formulating' and requires students to be able to apply and analyse ideas. Students engaged in a task ask for and listen to elaborations, justifications, and summaries from other group members. The fourth and final skill level is that of 'fermenting' when students are able to integrate ideas to form a concept or general principle. They are able to question, critique and evaluate peer ideas, and are able to develop and integrate other peer ideas into a new concept or application. This level aligns with synthesis and evaluation in Bloom's taxonomy (1956). At this level students are also able to handle controversy in a positive and constructive manner. Collaborative group work encourages vocalisation amongst peers and as the students develop the higher level thinking skills of formulating and fermenting they become more effective learners. Johnson, Johnson, Roy and Zaidman (1985) conducted research into the oral interactions of children (American Grade 4) and they found that a high proportion (90%) ohalk was task­ related. When they investigated the behaviours of high, medium and low achievers in the 32 groups they discovered that vocalisation had significantly more impact on achievement than listening. They noted that: Vocalizing task-related information orally striving to obtain more facts and information about the subject under discussion, giving explanations, providing rationales, and relating what is being learned to previously learned information, and disagreeing with other members' task-related conclusions were all significantly related to achievement. (Johnson, Johnson, Roy, & Zaidman, 1985, p. 318-19) They also found that medium achievers did not vocalize as much as high and low achievers in collaborative groups and concluded that medium achievers needed particular encouragement to elaborate in order to make more significant gains in achievement. From their results, Johnson et al. ( 1985) recommended that teachers encourage collaborative groups to elaborate upon material by providing a structure that increased the level of on-task vocalisation and introduced controversies so that students had to negotiate meanings from other students' task-related conclusions. 2.4.3 Think-Pair-Share Model (Lyman, 1992) Lyman (1981, 1992) developed a cooperative learning strategy called 'Think- Pair- Share': A question or problem is posed then the students are given time to think individually. The students cannot talk or raise their hands but may write down or draw a diagram to represent their individual ideas. At a designated time, indicated by the teacher, the students share ideas. The sharing of ideas results in a collective understanding, generated when they challenge and elaborate upon each other's thinking. Ideas may be subsequently shared with a larger group or the class. Using a variation of the Think-Pair-Share model in 33 mathematical collaborative learning investigations, Neyland ( 1994) found that use of individual think time at the start of an investigation resulted in more students contributing to the mathematics subsequently developed by the group. Students did not run with the first idea and they began to value the alternative thinking styles of their classmates as well as utilising a wider range of problem solving strategies. The Think-Pair-Share model utilises the concept of 'wait-time' . Wait-time, a pause between the question and a student's response, provides an opportunity for a student to formulate a thoughtful reply, to recall relevant prior knowledge, or validate a possible solution. This skill can be developed by the students in the forming and functioning levels of collaborative group skills (Thomson & Brown, 2000). Various researchers and educationalists have investigated the use of wait-time to improve the quantity and quality of student verbal responses. Rowe (1974) and Tobin and Capie (1980) found that when teachers paused for three seconds or longer after posing their initial question, and again after the student's initial response, that the length of student responses increased, more frequent unsolicited contributions were made, explanations became more logical, students supported ideas with evidence, participation by less able class members increased, and the number of questions and speculative responses increased. The use of wait-time has also been shown to contribute to gains made by tutees in peer-tutoring reading programmes and written language programmes (Medcalf, 1999; Medcalf & Glynn, 1987). 34 2.5 Peer-tutoring The initial collaborative discourse model considered for this study was a peer-tutoring programme. Peer tutoring is an instructional programme where students teach other students. The idea of student as teacher and learner is not new and has been documented as far back as Roman times. More recently, the pupil-teacher of the nineteenth century formed a structured part of classrooms in the United Kingdom and the Colonies (Limbrick & McNaughton, 1985). Teachers for large class numbers or diverse age groups in small rural schools have formerly used cross-age peer tutoring in New Zealand as a coping mechanism. Since the mid 1980s peer tutoring has gained in popularity because of the increased use of co-operative learning models (Medcalf, 1995) and individualised instruction, and because of perceived cost-effectiveness benefits (Jenkins & Jenkins, 1988). Research has shown peer-tutoring programmes to produce positive academic gains in mathematics (Beirne-Smith, 1991 ; Fuchs, Fuchs, Hamlett, Phillips, Karns & Dutka, 1997; Greenwood, Sloane, & Baskin, 1974; Maheady, Sacca, & Harper, 1987); spelling (Garcia­ V asquez & Ehly, 1992; Mallette, Harper, Maheady, & Dempsey, 1991 ; Greenwood, Daiquiri & Carta, 1997); reading (Kreuger & Brown, 1999; Medcalf & Glynn, 1987; Robinson, Glynn, McNaughton & Quinn, 1979); written language (Huggard, 2002; Medcalf, 1994); and where students use English as a second language or are intellectually impaired (Bar-Eli & Raviv, 1982, cited in Garcia-Vazquez & Ehly, 1992). Positive social gains have also been documented when the peer tutoring has been used directly to effect behavioural changes (Schunk, 1987) and to raise self-esteem as a by­ product of increased academic success (Medcalf, 1995). 35 The term 'peer-tutoring' is used loosely and widely in literature to describe buddy systems, role-models, peer-testing, peer-monitoring and peer-teaching, but will be considered within this study as a programme in which students are trained to use specific instructional strategies to promote the leaming of peers. The strategies used by the child in the tutor role include promoting higher order cognitive thinking by asking appropriate questions, waiting so his/her partner has time to think before responding, listening attentively, and giving positive feed-back and encouragement (King, Staffieri, & Adelgais, 1998). The central role of peer tutoring is to provide structured prompting of cognitively orientated talk in order to promote active construction through the analysis and integration of ideas. However peers talking while working on tasks independently of their teachers is not enough to "substantially further their mathematical understanding" (Thomas, 1994, p. iii). Effective training of peer tutors is imperative. Without training "peer tutors are likely to be less than helpful in supporting the learning of others" (Medcalf, in press). Peer-tutoring in this study is not considered the same as peer-mentoring (the buddy­ system), or peer-testing, which involves peers carrying out ' low order' tasks together to capitalise on the influence children have on each other and the comfort they have in working together. Some of the literature regarding peer tutoring encompasses these mentoring and testing programmes, particularly American literature. Peer tutoring is distinct from peer mentoring in that tutors are trained and monitored to carry out their role. For the purpose of this study peer tutoring will exclude 'buddy-support ' or peer testing such as that used by Greenwood, Daquiri and Carta (1997). Though Greenwood et al.'s programme bears the name 'peer-tutoring' it is in fact a peer-testing programme which is used to provide immediate feedback to a partner rote-learning a set of spelling words and mathematics basic facts. It is a competitive progranune, with the tutee receiving a series of points (for 36 correctly spelt words) to contribute to the team total. This type of programme does not promote "greater use of higher level reasoning strategies and increased critical reasoning competencies" (Medcalf, 1995, p. 11) which is inherent in the training of tutors for collaborative style learning, peer-tutoring programmes. 2.5.1 'Pause, Prompt and Praise' Model (Medcalf, 1992, 1994) Medcalf has developed a New Zealand based peer-tutoring programme for mathematics adapted from a research base associated with reading and written language. The mathematics peer-tutoring programme is "designed to help students identify errors in their thinking relating to their problem-solving efforts in maths, provide appropriate modelling and feedback and develop metacognitive skills" (Medcalf, p. 6, in press). In this programme peers are taught to perform four steps framed by the mnemonic WASP - Watch, Ask, Show, and Praise. The first step involves the tutor watching the tutee solve the problem. If the tutee has difficulties the tutor asks the tutee questions to redirect him/her to the next step or a previous error. If the tutee cannot proceed alone the tutor demonstrates (or shows) the next procedure in the problem or a similar example and then encourages the tutee to complete a similar problem independently. The last step is giving praise for completing the problem, or prompting the tutee as he/she works independently to complete the task with specific feedback on the issue the tutee was having difficulty with. Grant has trialled this approach in two pilot studies: one involving measurement with a class of nine and ten year olds, and the second (Grant, 2000, cited in Medcalf, in press) with twelve 9/10 year olds using mathematics games to develop computational skills. Both studies revealed increased self-esteem in tutors/tutees, increased on-task behaviour in all mathematics lessons, social benefits to the class and a higher average performance in the 37 post-unit test by the tutor group compared with the control group. In each study, the tutors were trained to respond within a particular mathematics unit (i.e., measurement and computational skills) and the tutors had specific mathematical knowledge beyond the level of the tutees. In contrast to Medcalfs programme, the tutor training in this study was developed so the instructional skills of the tutor could be applied generically to any strand of the mathematics curriculum. In this way the child in the role of tutor (or coach) did not have to be more mathematically knowledgeable about a specific task than the child in the role of tutee (see 2.6.3). In the study this was achieved by introducing a collaborative component in which both students in a pair shared responsibility for the functional group skills and completion of the task. The programme and training is explained in detail in Chapter 3. 2.5.2 'ASK to THINK-TEL WHY' Model (King, 1997) Sometimes peers, especially younger or less able students, are unable to verbalise their ideas so there can be no negotiation of meaning but by providing "rubrics, or key phrases, to explicitly encourage them to engage with each other's thinking" (Goos, 2000, p. 43) their ideas can be heard and evaluated. The 'ASK to THINK-TEL-WHY' programme was developed by King (1990, 1997) as an inquiry-based model of mutual peer-tutoring. Peer interactions were enhanced through the use of reciprocal peer-questioning strategies with generic stem questions. In King's model (1990) the question patterns created socio-cognitive conflict and forced the students to restructure their knowledge in order to respond to a particular pattern. They generated new examples and elaborated upon existing relationships between ideas in order to respond. 38 King found that students tended to interact at a "basic, concrete knowledge, retelling level" if left to their own devices, but by structuring the interaction with the provision of generic stem questions the students engaged "in the mutual exchange of ideas, explanations, justifications, speculations, inferences, hypotheses, conclusions, and other high level discourse known to promote peer-learning "(King, 1997, p. 222). Different kinds of questioning promote different levels of cognitive thinking. Asking, "What happened?" promotes lower order descriptive responses that recall facts. The information is restated within an integral context--reporting what happened during the concrete experience of the task. Asking "Why?" or "How?" type questions promote 'higher order' responses involving justifications, explanations and inferences. This encourages the integration of complex knowledge through making new connections between the task and external contexts (King, 1998). Similar models have been developed in Australia to assist peers, especially younger or less able students, to verbalise their ideas so there can be negotiation of meaning by providing "rubrics, or key phrases, to explicitly encourage them to engage with each other's thinking" (Goos, 2000, p. 43). These interactions engage students' higher order cognitive processes and assist them to build robust knowledge structures (King, 1997; King, Staffieri, & Adelgais, 1998). 2.5.3 Multiple Retelling Model (Cesar, 2001) Another programme which focuses on the development of higher order cognition uses didactic peer interactions with the multiple retelling of solutions. This model was developed by Cesar (1998), who conducted a four-year project into social interactions of didactic pairs 39 and their mediating role lll knowledge apprehension, cognitive development and skills acquisition in 5th to 11th graders. The didactic pairs were initially suspicious of one another and disinclined to work cooperatively. Problems were overcome by the implementation of rules, or a didactic contract, where each individual had to be able to explain both problem-solving strategies in order that either one of them could present their work during the class discussions. In this way they explained their own problem-solving strategy and asked questions and actively listened so that they would also be able to explain their partner's strategy. From this study Cesar(l 998) argued that the interaction itself is enough to promote better performances. This contrasts with Vygotsky's belief that the social interactions of a more competent peer or adult best. 2.6 Nature and Analysis of Classroom Discourse The complex interplay of content, context and relationships in the nature of discourse makes it difficult to select an adequate tool to measure and analyse classroom interactions. Three models were considered for this study: Thomas' model (1994); Johnson, Johnson, Roy, and Zaidman's model (1985); and King, Saffieri, and Adelgais' model (1998). The models and the implications suggested by the pilot research findings are discussed to provide a rationale for the intervention developed for this project. King, Staffieri, and Adelgais' model (1998), which measured the interactions in three peer­ tutoring conditions, was considered because it was developed to measure tutor responses in a pre-training and post-training situation. King et al. analysed the data using rates of interaction per minute and classified on-task interactions into three categories, those related to questioning, task statements, and supportive communication. This model required a question/statement or statement/statement interaction between tutor and tutee. After some_ 40 initial trial in the pilot study it was discarded because it was not able to be appropriately adapted to a multi-member group with equality of roles. Johnson et al. ' s model (1985) was considered because its development was supported by three decades of research by Johnson and Johnson in the area of co-operative learning. The particular model they used had been developed over three years as they observed co- operative groups and categorised the groups' oral interactions. The five-factor classification system resulted from factor analysis and input from Roy and Lyons' observational model of oral rehearsal and cognitive processing (1982, cited in Johnson et al. , 1985). The five categorisations are: • • • • • interactions exchanging task related information; interactions elaborating information; interactions encouraging each other to learn; interactions disagreeing with each other's conclusions; and non-task comments and sharing feelings . This model, which was trialled during the pilot study, was extremely simple to administer with instances of talk able to be placed clearly in one of the five-factor categories. The third model considered was Thomas' (1994) as it had been developed and used in New Zealand mathematics classrooms specifically to investigate the interactions of children as they worked in small groups independently of the teacher. Thomas classified transcriptions of children's small group interactions, which had been videoed, using a computer programme to encode and identify patterns in verbal data. When Thomas (1994) conducted her study on the nature of talk in the New Zealand junior 41 mathematics classroom, teachers were surprised that 91% of the talk was task-related which is consistent with Johnson et al. 's findings (1985). Thomas also found that the usual pattern for non-task related talk was that it was "brief, intermittent and interspersed with task- related talk" (p. 113). In most cases the children continued to work on the activity while they engaged in non-task related talk. However of the task-related talk, 53% was to do with social management aspects of the task and only 3 7% with cognitive aspects of the task. Thomas identified two further subcategories of cognitive talk (see Figure 1), that of reflection, when children considered their own thinking, and that of action talk, when they verbalised what they were doing, read aloud (reported on their writing), asked questions, gave help or commented to their peers about what they were doing with the expectation of a response. All Talk u u Non-task Task-related Social Cognitive Action Reflection Figure 1: Thomas' Model ofTalk (1994, p. 119). Thomas found that amongst young children there was very little reflective talk (1 %) unless the children were prompted by a teacher's question. This observation is also borne out by Higgins (1994) who found that the mathematical focus of an activity could be overrun by social and procedural problems in junior mathematics classrooms in New Zealand. Higgins also found that where teachers modelled mathematical language instead of everyday 42 language, and modelled discussion of an activity, that the children could apply these cooperative skills in later independent activities, by listening to explanations from other group members, asking questions of each other and explaining their thinking. Young­ Loveridge (1993) also found that younger children involved in junior mathematics classrooms required more monitoring, encouraging and modelling by teachers to remain on task and develop effective cognitive skills. In Thomas' study (1994), the majority of social talk was talk about the organization of materials for the task (29%) and about the organization of other children ( 16% ), and whose turn it was (20%). Social talk included a degree of social bargaining to gain acceptability and access to groups, articulation of the rules, disputes and comments about progress, such as who was winning a game/ who had the most/ who had completed their worksheet first. The amount of social talk increased as group numbers increased in size. 2. 7 Literature Review Summary This literature review summarises the positive social and academic outcomes attributed to peer-tutoring and collaborative group-work. It emphasises the importance of the teacher ' s role to select 'rich' engaging tasks at an appropriate level, model discourse patterns, and utilise effective discourse strategies in collaborative programmes. The review highlights the need for collaborative group skills to be taught in order to move students from basic group forming and functioning levels to effectively and consistently implementing higher order cognitive thinking skills at fermenting and formulating levels. 43 Chapter 3 Methodology 3.1 Introduction The aim of this action research study was to develop, implement, and refine a collaborative programme which has practical benefits to classroom teachers who wish to develop their students' higher order cognitive thinking in mathematics. The intervention was designed to support effective discourse structures of small groups working collaboratively on problem solving in the mathematics classroom. Scaffolding was provided by the teachers in the form of modelling and programme structure, and reinforced by competent peers during group work, in order to increase students' involvement in higher order cognitive interactions. The following questions formed the basis for the research as to the effectiveness of the intervention: 1. Does participation in the programme increase the frequency of higher order cognitive interactions between children in the mathematics classroom? 2. Are there 'oral flags ' which identify higher order cognitive thinking? 3. How did the students think that participation in the programme affected their academic achievement? 4. What changes did the teacher notice in individual/class interactions or attitudes when mathematical problem-solving? 3.2 Action Research Design The research design is based on a classroom-based action research model involving three cycles (Kemmis & Taggart, 1981 ). This report focuses on Cycle 3 (Main Study) of the action research cycle, provides an overview of Cycle 1 and Cycle 2 (Pilot Study), and shows their relationship to the third cycle. 44 Lewin (1948) and Collier (1945, cited in Ebbutt, 1985) independently pioneered the concept of action research. The action research model "proceeds in a spiral of steps each of which is composed of a circle of planning, action and fact-finding about the result of the action." (Lewin, 1948, p. 205). Action research was initially used to deal with community issues in social planning but has subsequently been employed in the education arena. Kemmis and Taggart (1981) developed Lewin's spiral action research model in Australia as the Action Research Planner and their draft was furthered almost immediately by Elliott (1981) in Britain as the Action Research Framework for Self-Evaluation in Schools. Elliott ( 1991) defines action research as "the study of a social situation with a view to improving the quality of action within it" (p. 61 ). Kemmis and Taggart (1981) summarised action research as a cycle (Figure 2), which involved planning, acting, observing, and evaluating: • • • • "to develop a plan of action to improve what is already happening; to act to implement the plan; to observe the effects of action in the context in which it occurs; and to reflect on those effects as a basis for further planning, subsequent action and so on, through a succession of cycles" (p. 7). This study design incorporates Kemmis and Taggart's spiral model within a social situation involving small groups of students engaged in collaborative mathematical problem solving. The action research model follows a cycle of planning, action, observation, and reflection, with adaptations made to the next level of the cycle after each phase. The main study focuses on the third cycle of the action research model. 45 Figure 2: Kemmis and McTaggart's Action Research Planner (1981) During the 1990s there was a rise in the amount of research undertaken within the context of the classroom; whereas before, the subject (s) undertook controlled, observed tasks and interviews outside the classroom. The action research model provided an ideal vehicle for increased teacher involvement in research projects (Ebbutt, 1985). However, the idea of teacher as researcher alarmed some members of the academic research community who believed a teacher' s research would not be academically rigorous (Carnine & Gersten, 2000). This argument was given support by those who did not differentiate ' normal' teaching practices from research, and who believed action research was an integral part of 'good teaching' and that it was inherent in the daily cycle of planning, assessment and evaluation in the classroom (Sharples, 1983, cited in Kelly, 1985). Others believed that by allowing teachers to maintain a dual role as researcher and teacher, 'coal-face' questions about learning and teaching would be more likely to be pursued in the microcosm of the classroom and that this in turn would provide impetus for further global research (Cochran­ Smith, & Lytle, 1993). 46 Ebbutt (1985) worked with Elliott using the educational action research model and created a broad classification system to differentiate daily teaching practices from those of 'teacher- researcher' (see Appendix 1). The role of teacher-researcher in the second and third cycles of this study falls within Ebbutt ' s ' classic ' action research model due to the degree of systemization, the testing of hypotheses beyond one classroom, and the collaboration undertaken with other teachers working in the same field of interest. The principles of planning, action, observation, and reflection are used for the systematic collection of information, and to reflect upon and plan change while maintaining flexibility and responsiveness to the context (Poskitt, 1994). 3.3 The Setting The research was undertaken at a three classroom rural primary school (Roll approximately 60, decile 41 ). Each of the three classrooms was multilevel: The junior classroom included all Year 1, 2 children; the middle classroom Year 3, 4, 5 children; and the senior classroom Year 6, 7, 8 children. The pilot study took place in the middle classroom in 200 I (see summary in 3 .6.1 ). The main study was undertaken over four weeks in Term 2, 2002, in the senior classroom. 3.4 Profile of the Sample Group A composite class of 25 Year 6, 7 and 8 children were involved in the collaborative training programme. The class had two teachers (teaching principal and release teacher) who took 1 Funding in New Zealand schools is currently allocated per capita according to a socio-economic decile rating from 1 to 10, with decile l being the lowest and receiving the greatest funding per capita. A school receives a decile number according to the average of the socio-economic location of the children's residential addresses. 47 joint responsibility for the implementation of the mathematics programme. Twenty children volunteered to be part of the research study but data analysis was completed for only 15 Year 6 and 8 children who were present for the entire training programme. The sample group consisted of four girls and two boys from Year 6, and three girls and six boys from Year 8. Nine identified themselves as Pakeha/European, three as Maori, two as Pakeha/Maori, and one as Maori/Pacific Islander. All the Year 6 children had been involved in the pilot study the year before. None of the Year 8 children had been involved in the pilot study. The class of twenty-five children from which the sample group was taken was concurrently involved in the 2002 Ministry of Education Numeracy Project. The numeracy teaching, during the period of the study, involved addition and subtraction of whole numbers and fractions. The classroom teachers used the draft Diagnostic Interview for the Numeracy Project (Ministry of Education, 2002c) to arrange sub-groupings and assess academic gains. 3.5 Tirneline Previous Year Pilot Study with researcher' s class.

The intervention plan was based on training pupil tutors using Medcalf and Glynn's (1987) 'Pause, Prompt and Praise' Model. In this model, tutors are specifically taught to praise tutees for self-corrections, correctly reading sentences, and the implementation of reading strategies. They are trained to pause to give the tutee time to think and to prompt if necessary with a series of reading strategies. These tutor-tutee interactions are designed to promote the high order cognitive skills of explanations, justifications, speculations, hypotheses, inferences, conclusions, and questioning. 49 Reflect Classroom Teacher and RTLB discuss the Peer-tutoring Programme and its high level of success in the development of the tutors' self-esteem, reading skill s and reading achievement The Classroom Teacher and the RTI ,B raise the question as to whether the principles of the programme can be generalised to other curr iculum areas such as writ ing and mathematics. Observe RTUJ makes Running Records of the tutors' reading behaviour and levels, before and after the programme. Revised Plan RTLB plans adaptation for written English and Classroom teacher plans adaptation for mathematics. Plan Use "Pause, Prompt and Praise" method of peer­ tutoring as an intervention for a child with a low reading level. Aim is to develop self-esteem, reading skills and readin g achievement for th is child. Act RTLB implements a peer­ tutoring programme with four children as tutors. Classroom Teacher is instructed in th e principles of the programme and schedules daily tutor/tutee meetings. Children act as tutors for four members of junior class. Figure 3: Cycle 1 of this Action Research Study: The classroom teacher becomes involved in research at Ebbutt's Self-Evaluation Action Research Mode. (Refor to Appendix I). The action phase of Cycle 1 invo lved the RTLB implementing the peer-tutoring programme with fo ur children. The classroom teacher was instructed in the principles of the programme and scheduled daily tutor/tutee meetings in which the fo ur students tutored junior class members in reading. The observation phase involved the RTLB recording the tutors' reading levels and behaviours using the Running Record system (Clay, 1985) before and after the peer-tutor training. The classroom teacher and the RTLB reflected on the success of the programme as an intervention and discussed whether the principles of the programme could be generalised and implemented as an intervention in other curriculum areas. 50 In the second rotation of the action research cycle the classroom teacher, now in the role of researcher, developed an intervention based on Medcalf s peer-tutoring procedure (WASP) for mathematics (Medcalf, in press). Medcalf had adapted this model from the 'Pause, Prompt and Praise' for reading (Glynn & Medcalf, 1987). The following steps outline this procedure: W=Watch Watch as your friend shows you how they work out the problem. A= Ask Ask questions to check out your friend ' s understanding E.g. "How did you get that answer?", "What do you think the next step is?", "Can you see where you went wrong?". Sometimes asking the right question will be enough for the tutor to realise their error and be able to self-correct or complete the problem independently. If so the tutor may skip the next step and proceed to prompt and praise. S=Show Show your friend how to complete the problem. This will often involve modelling a particular step in the process that a tutee is experiencing difficulty with and/or completing incorrectly. The tutor can assist the tutee to complete a similar problem with their help and encourage the student to then attempt another example independently. P=Prompt and Praise Prompt your friend to complete a similar problem on their own and praise their efforts. The tutor prompts the tutee to attempt a similar problem independently. Before doing this the tutee is asked to tell the tutor what they will do to solve 51 the problem and complete the task. The tutor watches and provides specific positive feedback with special emphasis on the step or issue that the tutee was having difficulty with. This pilot study, Cycle 2, aimed to test Medcalf's findings of social and academic benefits through replication, but also to evaluate and refine the type of questioning format in the ' Ask ' phase. Questions were specifically designed to increase higher order thinking and scaffolding. The pilot study, undertaken within the teacher-researcher's own class of (twenty-four) Year 4 and 5 children, involved making anecdotal observations and audio recordings of classroom peer interactions during the collaborative group work in mathematics. The Year 4/5 class was concurrently involved with a pilot study for written language with the RTLB (Huggard, 2002). This reinforced the establishment of a classroom community in which students learned cooperatively and questioned each other's thinking. 52 Reflect Think-Pair-Share model best promoted mathematical learning with peer support by requiring individual accountability, idea construction through negotiation of meaning and justification by presenting ideas to partners and the wider group. Thomas' model has NZ research base and easy to use initial categories of on task/ olI task, and social/cognitive interactions. Need to redefine subcategories of cognitive reflection and cognitive action. Observe Transcribe and analyse interactions of children engaged in mathematical problem solving in small groups. Make anecdotal observations of interactions that appear to promote mathematical learning amongst peers. Plan Review literature for: 1. Examples of peer-tutoring, cooperative/ collaborative learning programmes. 2. Analysis tools for discourse in the mathematics classroom. 3. The use of cognitive thinking skills to promote learning. Use these literature ideas to develop and trial a pilot intervention which promotes peer learning in the mathematics classroom. Act 1. Use WASP and Think-Pair-Share learning models. 2. Trial ways to quantify qualitative data in the analysis of classroom interactions: Thomas' Model (1994); Johnson et al. 's Model (1985); and King et al's Model (1998). Revised Plan Refinement of pilot programme to promote ·'wait-time", specific feedback , multiple presentations of solutions with explanations and justifications. Reduce off-task and social interactions by careful selection of rich tasks by teacher and reinforcement of cooperative group skills with teacher modelling. Define collaborative learning cf. cooperative learning. Redefine cognitive subcategories in terms of Bloom' s taxonomy, as lower or higher order cognitive thinking. Identify more verbal flags that indicate cognitive thinking. Figure 4: Cycle 2 the Pilot Study: The Teacher as Researcher in Ebbutt's Classic Action Research Mode. (Refer to Appendix 1 ). The data from the second cycle was quantified and analysed using three models of discourse analysis: Thomas (1994), Johnson, Johnson, Roy, and Zaidman (1985), and King, Staffieri, and Adelgais (1998). Johnson et al.'s model (1985) enabled children's talk to be clearly classified into either one category or another. Though it was the easiest of the three to administer for collaborative 53 groups, it did not give the researcher enough information about the type of information exchanged. Thomas' model (1994) was both hierarchical and linear which suited discussion that modelled a hierarchical model of cognitive thinking such as Bloom's taxonomy (Bloom, 1956). The model also defined the concept of a ' turn' as the utterance made by one child before another child speaks. A tum could be a single word, a phrase, or one or more sentences (Sharan & Sachar, 1988, cited in Thomas, 1994) and this was used to define instances of data. Though the Thomas' model distinguished the classification of cognitive talk into subcategories of action and reflection a child' s tum could be enmeshed with elements of both. King et al. ' s model ( 1998) required a question/ statement or statement/statement interaction between tutor and tutee and was found to be inappropriate for analysing collaborative group discourse. These considerations alerted the researcher to the need to clearly match the method used to analyse the children's interactions with either the collaborative group model or peer­ tutoring, dependent upon the research questions to be considered in the main study. For this reason, Lyman's Think-Pair-Share method of cooperative learning (1992) was trialled as an alternative to Medcalf's WASP technique (in press). The Think-Pair-Share method promoted mathematical learning with peer support by requiring individual accountability, idea construction through negotiation of meaning, and the development of higher order cognitive thinking when students elaborated and justified their ideas and their solutions to partners and the wider group. 54 The pilot study, conducted over twenty weeks for eighty hours, provided insights into factors which supported effective mathematical learning by children in collaborative groups. These factors included: 1. Careful task selection at an appropriate level to reduce social/procedural task-related talk and increase cognitive task-related talk; and to maintain students in their zone of proximal development (Vygotsky, 1978). 2. Modelling and the provision of feedback by the teacher (and other groups) to develop and encourage collaborative strategies which reflect positive interdependence including: • • • • • listening to explanations from other group members; asking questions to clarify own/other's thinking; providing evidence to justify conclusions/solutions ("What's your evidence?"); praising and encouraging with positive specific feedback; and giving and receiving help . 3. Development of mathematical strategies by teaching modelling of mathematical language. 4. Provision of individual thinking time to allow for the development of multiple strategies as a base for negotiating meaning and solutions. 5. Group size effects, particularly with reference to maturational age. Pairs usually resulted in each partner sharing the talk equally (50% of all talk). Groups of three or four could be dominated by a particular member. 55 In preparation for Cycle 3, which was to comprise the main study, the researcher used the information gained in the second cycle to: • Select the Think-Pair-Share technique as the basis for collaborative learning in small groups. • Select rich, appropriately levelled tasks to reduce task-related social interactions. • Reinforce and model cooperative group skills by the teacher to reduce off-task social interactions. • Select Thomas' model to analyse interactions but with the modification that the subcategories of cognitive interactions were replaced with lower cognitive interactions and higher cognitive interactions. The lower cognitive interactions were defined as those involving recall and recognition (knowledge) and translating symbols and words (comprehension). The higher cognitive interactions were defined as those, which involved elements of application, analysis, synthesis and evaluation based on Bloom's taxonomy ( 1956). • Define and use the term 'collaborative· instead of ' cooperative'. • Be aware of phenomena such as children using 'verbal flags ' (e.g., 'so'), to identify the linking of ideas and hence higher cognitive thinking. The next cycle of the action research study was to investigate the use of collaborative training to promote increased higher-level cognitive interactions between children. 56 3.6.2 The Main Study - Cycle Three The main study, Cycle 3 (see Figure 5), involved the initiation of the collaborative/peer- tutoring training programme based on Lyman's Think-Pair-Share model (1994). The aim of the intervention was to develop the interpersonal skills necessary for effective collaborative work and to develop the higher order thinking skills of the students. Reflect Verbal nags were identified, the link (conjunctions), the run-up (rehearsal), wail-time (demand for individual cognitive thinking time). Arc there more? Was task selection to keep children motivated and in ZPD the primary reason the number of cognitive interactions increased? Did the number of higher cognitive interactions increase significantly? What limitations faced the programme? Did the children have enough forming and fun ction ing skills to reach fermenting and formulating levels? Observe Interactions of children recorded as transcripts before and after the training programme. Transcripts analysed. Response questionnaire completed by children aficr the programme. Verbal response and anecdotal comments given by classroom teachers. Figure 5: Cycle 3 The Main Study. Revised Plan Future resca rch Act 25 children work with researcher in 3 collaborative groups to develop interpersonal group skill s and thinking skills for collaborative learning. Programme rein forced by teacher modelling and small group work in the classroom. Plan Use Lyman·s Think-Pair­ Share method as an intervention for a mathematics class. Aim is to develop interpersonal ski lls necessary for effective collaborative work and higher order thinkin g ski lls. The collaborative-peer training was developed so that the students would advance through Johnson and Johnson's '4Fs' group skills: forming, functioning, formulating, and fermenting. In the initial group discussion between the researcher and students, basic self- 57 management skills were discussed at the group 'forming' level. These included principles of courtesy such as orientating the body to the speaker/listener and one person speaking at a time, as well as principles of encouragement such as no 'put downs', including all group members in discussion, and praising attempts or ideas. Four key strategies were discussed in subsequent sessions to develop the students' higher­ level group skills of functioning, formulating and fermenting. These strategies included: • wait and give individual's time to think for his/herself; • be specific with feedback; • give help when asked in the form of a specific strategy, idea or question rather than an answer; and • support agreement or disagreement with evidence. The process involved two key ideas for the teacher: modelling and maintaining the ' 4Fs' in class discussions and group work, and selecting rich tasks which maintained the students in their ZPD. Initially during the training, the students worked in pairs using Medcalf's (1992) peer­ tutoring model. One member of the pair adopted the authority role of tutor or coach and was responsible for the use of the instructional prompts while his/her partner solved a mathematical task. When the tutee had solved his/her problem (or developed a solution to the best of his/her ability with the aid of the tutor) the pair swapped roles and the other partner completed a different problem with the same mathematics concept. The tutor/tutee role was alternated so that individuals would develop a greater awareness of the effects of their feedback. Pairs were encouraged to reflect and comment on the implementation of the 58 collaborative group skills and their own learning. The positive interdependence of Lyman's Think-Pair-Share model (1992) of collaborative learning was incorporated into the next stage of training. Individuals worked on problems by themselves for a specified time and then they shared their solution and the evidence to support their conclusion with a partner. If a problem had a finite solution the partners compared answers and evidence. An identical answer meant they were either right or both wrong, and two different answers meant they needed to review their evidence to convince their partner their solution was correct. When the partners reached an agreed solution they presented the solution and evidence to another pair. Multiple solution paths were viewed and compared. Any answer could be challenged as long as the challenge was supported by reasoned argument. Open-ended questions with more than one solution were approached in a similar manner. The students had individual thinking time and then presented their solution to a partner. If a partner was not convinced of the alternate solution he/she again challenged the partner for more corroborative evidence and the partner was required to justify the solution with more information. Alternative solutions and evidence were presented to the entire group. The children were encouraged to compare their solution and reasoning to those of other presentations. In this way each different solution was considered, and flawed solutions were challenged and discarded. Variations of this model occurred when a pair worked together and presented their solution to another pair and then the wider group; or individuals worked on the same problem and presented their solution and reasoning to a partner and then combined their solution and evidence or selected what they considered the strongest solution and most convincing evidence to present to the wider group. 59 The following extract is a recording of a cooperative group work training session, which shows the Think- Pair- Share pattern used by two boys during problem solving and the reinforcement of the model by the teacher. Teacher: [Speaking to whole class] I want you to work on problem four on page ten. 2 You 'fl have about ten minutes to work out your own answer. You can have more time if you need it. I'll check in about ten minutes. Remember this is your own time for ten minutes. You can write stuff down, draw pictures but don 't talk to your partner. You 'll have a chance to compare ideas after. Have you found page four Jeffery? That 's right ... the question at the bottom. [The teacher reads the problem aloud both to focus the group and because several children have reading difficulties]. Jan needs exactly 5 litres of water. She has only these two containers. How can Jan use her containers to measure exactly 5 litres ofwater? ... Okay? ... gofor it. [Teacher withdraws to her desk and observes the class. After four minutes she notices an early finisher and comments aloud.] If you have an answer to the problem you might like to write it down or draw a picture so it 's easy for your partner to understand what you've done. [Ten minutes passes]. Does anyone want more time? ... Okay Cherie, why doesn 't your partner check her solution until you 're ready. The rest of you can show your ideas to your partner. Remember if you see something you like or realise there 's something you want to change you can change it. I want to hear people backing up their ideas with evidence.
