本文描述了一个问题求解模型和一个问题解释工具。掌握一种解题方法的运用对人类解题能力的进步起着至关重要的作用。我们的研究旨在完成一个ITS，帮助学生掌握使用的解决方案的方法。一个能解决例题的学生不一定能解决任何习题。因此，解释这两个问题之间的等价性变得很重要。为了实现解释，我们提出了一个问题解决模型称为MIPS，它提供了一个框架和词汇表来描述解决方法选择的过程。基于MIPS实现了问题求解模块和问题解释模块。问题求解模块能够解决多种算术应用题。此外，还描述了求解方法的选择过程。问题解释模块从描述中导出问题解释。
This paper describes a problem solving model and a problem explanation facility. Mastering the use of a solution method plays a crucial role in the progress of human problem solving capability. Our research aims at accomplishing an ITS which assists a student to master the use of a solution method. A student who can solve an example problem cannot always solve any exercise problems. Thus it becomes important to explain the equivalence between the two problems. In order to realize the explanation, we propose a problem solving model referred to as MIPS which provides a framework and vocabularies for describing the process of solution method selection. A problem solving module and a problem explanation module have been already implemented based on MIPS. The problem solving module is capable of solving several kinds of arithmetical word problems. Moreover, it describes the process of solution method selection. The problem explanation module derives the problem explanation from the description.
