摘要
影响代数应用题难度的一个重要因素是它的文字表述,将文字表述分解为语量、语境、语序和关键词的隐蔽程度4个指标,通过实验逐一研究每个指标与解题效果的关系.结果显示:4个指标对解题效果均有一定程度影响,其中语量和语境的影响最为显著.因此,通过一定的教学策略有目的地对上述指标进行干预可以提高学生解决代数应用题的水平.
An important factor that influences the degree of difficulty in solving algebra applied problems is its character expressions. Character expressions are divided into four targets, including the amount of words, the context, the order of the words and clue words. In this study, we found out the relationship between them and the effort on solving problems by doing experiments one by one. The result showed that each one has some influence on the effort, especially the amount of words and the context. Therefore, the students’ ability of solving algebra applied problems can be developed by controlling these four targets through certain teaching strategies.
