We try to demonstrate the improvement of intelligent computer-aided instruction (ICAI) by the development of an interactive help system, which checks hypotheses postulated by the user during the problem solving process. The system is capable to recognize even incomplete proposals and contains the knowledge to generate complete solutions of the programming tasks. Thus the interactive help system adaptively supports the planning activities of the user. This is done by a goals-means-relation (GMR) which contains the domain-knowledge to analyze and synthesize ABSYNT-programs. At present this knowledge is worked out for 37 tasks in our curriculum and is condensed into 462 rules. The complexity of the solution space is rather astonishing. The system is capable to recognize and generate several millions of solutions even if height of ABSYNT-trees is restricted to five nodes.
