“放”而有度的小学数学课堂构建

The Construction of Elementary School Math Class Based on the Idea of Give Play to Students’ Subjectivity Measurably

基于＂放＂而有度数学课堂的理论基础,文章对以往＂正数和负数＂最后一个环节的活动设计提出了质疑和反思,并进行了重新优化设计,在实践中再次对活动进行反思重构,真正践行了＂放＂而有度的数学课堂,并探讨了＂放＂而有度思想在小学数学教学中的应用策略。

Based on the idea of give play to students’ subjectivity measurably, the paper puts forward some questions andreflections on the design of the last link of “positive and negative numbers”. Reconstructed the activity design in the process ofpractice, and explored the strategies of using the theory of give play to students’ subjectivity measurably.
