作者一直在开发一个计算题训练系统，旨在提高大学生的计算能力。计算题的难度似乎主要取决于计算公式及其解法的复杂程度。然而，我们已经证实，即使解使用相同的计算公式，计算问题的表示也会影响答案的正确率。在此背景下，我们的问题训练系统从问题库中提取适合学生能力的问题并提供给学生。问题数据库存储了许多具有不同表示形式的问题，即使它们是使用相同或相似的公式解决的。本文讨论了我校进行的一些实验、计算题的表征与难度之间的关系以及计算题训练系统的出题策略。
The authors have been developing a calculation question training system that aims to improve university and college students’ calculation abilities. The difficulty of calculation questions seems to depend mainly on the complexity of the calculation formula and its solution. However, we have confirmed that the representations of calculation questions can affect the rate of correctness of answers, even when the solutions use the same calculation formula. Against this background, our question training system extracts questions adapted to the students’ ability from a question database and offers them to the student. The question database stores many questions with different representations, even though they are solved using the same or similar formulas. In this paper, we discuss some experiments executed at our university, the relationship between the representation of calculation questions and their difficulty, and the strategy for offering questions for the calculation question training system.
