Abstract
Throughout life, we continuously accumulate data, information and
knowledge. The ability to recall much of this accumulated knowledge
commonly deteriorates with time, though some forms part of what is
referred to as tacit knowledge. In the context of education, students access
and interact with a teacher’s knowledge in order to create their own, and
may have their own data, information and knowledge that could be added to
teacher’s knowledge for everyone’s benefit. The realization that students can
contribute to enhancing personal knowledge is an important cornerstone in
developing a mentor (teacher, tutor and facilitator) focused knowledge
system.
The research presented in this thesis discusses an integrated framework
that manages an individual’s personal data, information and knowledge and
enables it to be enhanced by others, in the context of a blended teaching and
learning environment. Existing related models, structures, systems and
current practices are discussed.
The core outcomes of this thesis include:
• the virtualMe framework that can be utilized when developing
Web based teaching and learning systems;
• the sniplet content model that can be used as the basis for sharing
information and knowledge;
• an annotation framework used to manage knowledge acquisition;
and
• a multimedia object (MMO) model that:
o allows for related media artefacts to be intuitively grouped
in a logical collection;
o includes a meta-data schema that encompasses other metadata
structures, and manages context and referencing; and
o includes a model allowing component parts to be reaggregated
if they are separated.
The virtualMe framework provides the ability to retain context while
transferring the content from one person to another and from one place to
another. The framework retains the content’s original context and then
allows the receiver to customise the content and metadata so that the
content becomes that person’s knowledge. A mechanism has been created
for such contextual transfer of content (context retained by the metadata).
