A Method of Constructing Case-base for Evaluation Assistant of Novice Programs

This paper presents a method of indexing cases for case-based evaluation assistant systems of novice programs. Program lists in evaluation cases should be represented in intact target programming language, because special forms of program lists put heavy burdens on teachers who are users of the systems. However, intact forms of program lists cannot cover that many variations. Therefore, indexes to cases should be constructed by using information of generalized program lists in order to expand the variations of program lists covered by one case. We propose a three level index of evaluation cases for novice programs written in a simple assembly language. Practical use in actual classes and retrieval experiments demonstrated the effectiveness of the proposed index method.
