The development of intelligent hypermedia courseware, for design and technology in the English National Curriculum at Key Stage 3, by the sequential combination of cognition clusters, supported by system intelligence, derived from a dynamic user model

The purpose of this research was to develop an alternative to traditional textbooks for the teaching of electronics, within Design and Technology at Key Stage 3, in the English National Curriculum. The proposed alternative of intelligent hypermedia courseware was investigated in terms of its potential to support pupil procedural autonomy in task directed, goal oriented, design projects. Three principal design criteria were applied to the development of this courseware: the situation in which it is to be used; the task that it is to support; and the pedagogy that it will reflect and support. The discussion and satisfaction of these design criteria led towards a new paradigm for the development of intelligent hypermedia courseware, i.e. the sequential combination of cognition clusters, supported by system intelligence, derived from a dynamic user model.
A courseware prototype was instantiated using this development paradigm and subsequently evaluated in three schools. An illuminative evaluation method was developed to investigate the consequences of using this courseware prototype. This evaluation method was based on longitudinal case studies where cycles of observation, further inquiry and explanation are undertaken. As a consequence of following this longitudinal method, where participants chose to adopt the courseware after the first trial, the relatability of outcomes increased as subsequent cycles were completed. Qualitative data was obtained from semi-structured interviews with participating teachers. This data was triangulated against quantitative data obtained from the completed dynamic user models generated by pupils using the courseware prototype.
These data were used to generate hypotheses, in the form of critical processes, by the identification of significant features, concomitant features and recurring concomitants from the courseware trials. Four relatable critical processes are described that operate when this courseware prototype is used. These critical processes relate to: the number of
computers available; the physical environment where the work takes place; the pedagogical features of a task type match, a design brief frame match and a preferred teaching approach match; and the levels of heuristic interaction with the courseware prototype.
