数学思维的过程需要表达,数学思考的结果需要展现.“课堂展示”可以打开学生思维的闸门,只有敞开这扇大门,才会实现资源共享.因而“展示”成了数学课堂中交流的重要方式,下文将结合我的数学课堂教学实例,对展示的层次与展示的作用作一个简单的归纳:一、在关键处展示,展出通性通法,理解算理比较适合中等生展示问题呈现:书法小组有12人,绘画小组是书法小组人数的13,摄影小组是绘画小组的34,摄影小组有多少人?
The process of mathematical thinking needs to be expressed, and the result of mathematical thinking needs to be demonstrated. “Classroom Presentation ” can open the gate of students’ thinking, and only by opening this door can resources be shared. An important way to communicate, the following will be combined with my math classroom teaching examples, the display of the level and the role of a brief summary: First, at the key at the show, show Tonglv method, to understand the mathematical more suitable for middle school students The presentation shows: 12 calligraphic groups, 13 drawing groups, 34 photography groups, and 34 photography teams.
