It is very important task for a student to compare between problems in exercises. To help him/her to compare between problems in an educational system, it is necessary to define a problem representation and control the comparisons by using the representation. In this paper, we propose a representation for comparing between two problems in education of recursive programming. Second, we present a design of functions of comparing between problems which are (a) generating explanation of differences and similarities between two problems, (b) searching problems for comparisons, and (c) generating exercises of grouping problems. We have also implemented an educational system which helps a student to compare between two problems. We describe an experimental evaluation of the functions.

プログラミングを行うためには,プログラムは少なくとも,プログラムの動作について明確に理解しておく必要がある.しかしながら初心者の場合プログラムの個々の命令の振舞いを理解できても,プログラム全体の動作を正しく理解できなかったり,プログラム仕様から動作を想定できない場合がよく見られる.このような初心者を対象とする場合,動作とプログラムコード,動作とプログラム仕様の対応関係について説明することが重要となる.本論文では動作の理解が特に難しい再帰プログラムを対象に,プログラムの動作を介したプログラミングを支援する知的教育システムについて述べる.筆者らは再帰プログラミングのモデルを想定した上で,学習者にとって理解が容易となるようにプログラムの動作を表現し,これをプログラムの振舞いと呼んでいる.本論文ではこの振舞い表現を用いて,再帰プログラムの設計過程および理解過程を支援する方法について論じる.特に,雛形を用いた解法による設計過程の支援ならびに,振舞い表現の可視化による理解過程の支援について述べる.更に振舞い表現の評価実験についても述べる.

This paper aims at designing an instructional system that teaches recursive programming to a novice programmer. In order to reduce a cognitive load which the novice bears in constructing algorithms in recursive programming, we propose the algorithm and solution for constructing the algorithm. The algorithm represents simple recursion as two iterations. We had an experiment to confirm if the instruction based on the solution is more effective than a programming textbook. As a result, the instruction had a significant effect. We have also designed an instructional system which helps the novice adaptively acquire the solution.
