This study addressed the assessment and development of problem-solving skills of college students. A mathematics-oriented computer-assisted instruction (CAI) program with an embedded general problem-solving strategy was developed. A related computer-managed instruction (CMI) module maintained student progress and phased out the problem-solving assistance as students became more skilled at solving problems. Effectiveness was evaluated by pre- and post-tests and questionnaires administered to 37 students who used the CAI program and a control group of 23 students who received no CAI. Improvement in the mean test scores of the group using CAI was approximately twice that of the control group, and responses to the questionnaire showed that the students in the experimental group enjoyed using the CAI program and felt that they learned from it. Extracts from the pre-/posttests and a copy of the questionnaire are appended. (45 references) (Author/MES)
