Enhancing student decision making in technological practice : a thesis submitted for the degree of PhD Education, Massey University, Palmerston North, New Zealand
(Massey University, 2014) Harwood, Cliff
This research focused on identifying the influence of conceptual understandings of technological modelling on students’ ability to make informed decisions when developing technological outcomes. It also explored the relationship between student achievement in the components of Technological Practice (brief development, planning for practice, and outcome development and evaluation) and their concepts in technological modelling. An emancipatory action research design was adopted for this study due to its responsiveness to the context in natural settings, and focus on critical reflection with intent to improve understandings and practice within social settings (Elliot, 1981; Poskitt, 1994). Quantitative and qualitative data were gathered using a mixed methods approach, consisting of a questionnaire, portfolio evidence and interviews. These data were gathered over three research cycles from 27 student participants who were in years 12 and 13 in 2008 and 2009 respectively. Category labels were developed from literature and an initial exploration of the data, to describe the ‘nature of reasoning’ and the ‘nature of practice’ students applied when engaged in undertaking technological practice to address a need or opportunity. The category labels allowed exploration of the relationships between the different forms of reasoning students employed when undertaking technological practice. These labels also enabled exploration of how reasoning informed student decision making and supported their justifying that the technological outcomes they developed were ‘fit for purpose’. The research found a positive connection between student understanding of concepts underpinning technological modelling and their curriculum achievement in the components of Technological Practice - brief development, planning for practice, and outcome development and evaluation. That is, when student understanding of technological modelling were enhanced their competency to undertake brief development, planning for practice, and outcome development and evaluation also increased. The research also showed that students who held more sophisticated understanding of technological modelling (Level 6 or above) could discuss how practical and functional reasoning work together to identify risk, and enable informed and justifiable design decisions to be made. In addition these students could also justify the technological outcomes they developed as ‘fit for purpose in their broadest sense’ (Compton, 2007; Compton & France, 2007b). In contrast, those students who held low curriculum level understanding of technological modelling (below Level 5) demonstrated a lack of ability to integrate practical and functional reasoning to inform their decision making when undertaking technological practice. As such, their decision making most often centred on determining the physical description of a technological outcome, with little apparent thought to social-technical considerations that underpinned its development, and later implementation into its intended environment. This research concludes that when teachers support students to develop their curriculum understandings of technological modelling their ability in undertaking technological practice becomes more sophisticated, and they are equipped to develop technological outcomes that they can defend as ‘fit for purpose in their broadest sense’ (Compton, 2007; Compton & France, 2007b). The research findings therefore present a case for teachers to place an explicit emphasis within their teaching programmes on enhancing student conceptual understandings of technological modelling.
'Technologists' alongside : impact on student understandings in technology : a thesis submitted in partial fulfilment of the requirements for the degree of Master of Education, Massey University, Palmerston North, New Zealand
(Massey University, 2007) Harwood, Cliff
This research focuses on ascertaining the impact of technologists working alongside students; in particular the influence their involvement has on their understandings of and about Technology. The research was conducted within an interpretive paradigm. Quantitative and qualitative data were gathered using a mixed methods approach which consisted of a written questionnaire, followed by purposive interviews. The participants in the study were students in years 11 and 12 in 2005. Data from these participants were also gathered in 2006. The research findings identified that when students work alongside a technologist(s) to resolve problems embedded within real-life contexts, their concepts of technology and its purpose are enhanced. These findings also highlighted the importance of ensuring that student learning intentions (those learning outcomes which are planned) are shared between all parties involved in the learning environment (teachers, practicing technologists and students), so that interactions between students and technologists have a positive influence on student learning. This research concludes that the involvement of practicing technologists, in student learning in technology education, offers the potential to enhance student's technological practice and their learning in technology generally.
