思维的活动经验,是作为策略性、模式性、方法性内容出现的经验,它们带有明显的“再抽象”、再加工痕迹,是基于个体对思维活动过程的再现所致.串起学生的思维火花,让数学思维长成理性经验,能够有效地提升孩子的思维高度,增强思维品质,提升数学素养.一、学难,教难,为何难高年级同学数学思考现状分析:1.瓶颈一:直观感受高于理论推理如乘法分配律的运用:①512×49+712×49,②101×
The activity experience of thinking is the experience that emerges as a strategic, modal and methodical content, with obvious “re-abstraction ” and traces of re-processing based on the individual’s reproduction of the process of thinking activities. Students spark of thinking, let mathematical thinking grow into a rational experience, can effectively enhance children’s thinking, enhance the quality of thinking, improve math quality .A difficult, difficult to teach, why is it difficult for senior grade math thinking analysis: 1. Bottleneck 1: Intuitive feeling is higher than the theoretical reasoning, such as the use of multiplication distribution law: ① 512 × 49 + 712 × 49, ② 101 ×
