A multimethod generative CAI system for remedial mathematics

A computer-assisted instruction system for remedial mathematics has been written to yield four teaching methods based on two orthogonal variables: (1) With ad hoc frame orientation (AFO), training modules have a fixed order for all students, strict performance criteria must be met before moving to new modules, and students can ask only for problem solutions. With information structure orientation (ISO), the first two AFO conditions are dropped and students can also request partial answers and hints. (2) A confluent (affective) mode contrasts with didactic instruction by adding use of given names, self-report of moods, relaxation procedures, some communication with another student, and so on.
