中学生数学解题表征的一次调查测试

Survey for Middle School Students' Representation of Problem Solving

问题表征是指问题或任务在问题解决者头脑中是如何呈现、如何表现出来的.问题表征依赖于人的知识经验,也受到注意、记忆和思维的影响.中学生问题表征处于3个不同水平:(1)程序性表征;(2)发展的表征;(3)概念性表征.经常要求学生解释数学表达式的意义,是促进学生概念性理解的重要手段.

From a test, middle school students?mathematical representation level were analyzed, their present understanding about Gougu theorem were explored, and were deeply reflected on its teaching.
