自我评估是小学高年级学生理解数学问题的高阶层级。通过观察和分析小学生对数学题目的自我评估与改进发现,小学生在模拟出题解题和自我评估的学习过程中,不仅可以突破数学就是计算的迷思,而且不断提升对于数学问题的理解和表征能力,在考虑数学问题情境之外还考虑数值关系,特别是关注可以合理解题的数值讯息及其关系,并最终达成透彻理解数学题目的内容和结构。
Self-assessment is a high-level hierarchy in understanding elementary mathematics for upperclassmen. By observing and analyzing the pupils’ self-assessment and improvement of maths, we found that pupils can not only break through the myth of computation but also improve their comprehension and characterization of math problems in the course of simulating problem-solving and self-assessment Ability to think of numerical relationships in addition to situations of mathematical problems, with particular attention to numerical messages that can reasonably solve problems and their relationships, and ultimately to a thorough understanding of the content and structure of math topics.
