数学课堂教学,一般来说有两次集中反馈。第一次在传授新知识后,教师列出几道题目,指名学生上台板演(其余学生可在座位上做),然后师生一道评讲板演的结果。第二次反馈在下课前,要求学生独立完成作业。学生在独立作业中强化了新知识,使所学知识得到进一步的巩固和提高。由于独立作业是数学课的不可缺少的组成部分,所以第二次反馈有着重要 Math class teaching, in general, there are two focused feedback. After teaching the new knowledge for the first time, the teacher listed a few questions. The named student took the stage performance (the rest of the students were seated in the seat). Then teachers and students talked about the results of the performance. The second feedback before get out of class, require students to complete their homework independently. Students strengthen their new knowledge in their independent work and further consolidate and enhance their knowledge. Since independent assignments are an integral part of math classes, the second feedback is important
