A Framework Model for CAL Programs

A framework model for the design and implementation of computer assisted learning (CAL) programs is described. The model is flexible enough to accept most domains and can deliver knowledge in a simulated form, similar to that of a teacher in a classroom. A major feature of the model is its division into four submodels: the knowledge base, the dialogue, the plan, and the task specification. The knowledge base has been considered as two classes of knowledge: structural and functional. The construction of the dialogue submodel as a tree structure co‐ordinates domain specific reasoning with the plan submodel which generates a wide range of possible formats for user response.
