“…The results of the study concluded that, although the model as developed provided the structure and documentation to plan full implementation, it was not feasible for an individual to maintain and support the model and that it was difficult to transfer the model and its programming language from one piece of computer hardware to another. Coyle (1985) noted a gap between state-of-art educational research and what is practiced today. The majority of available Computer Assisted Learning (CAL) software at the time, however, lacked appropriate design features that would enable the computer to meet its potential for an infusion of problem solving, information processing, and model building skills into the current curriculum.…”
