一、问题的提出 2001年11月份,笔者教授的是初一B层的数学课,而我们分层只有A、B两层,B层中有相当一部分学生数学基础较差,学习习惯也不太好,对数学缺乏兴趣,并且相对于A层学生,B层学生的课堂反应能力和接受能力都弱一些,尤其是自信心差,不喜欢举手回答问题,对教学过程参与的热情低。 First, the problem was proposed in November 2001, the author taught the mathematics class of the first B level, and we have only A, B two levels of stratification, a considerable part of the B-level students have poor mathematics foundation, learning habits are not too Well, there is a lack of interest in mathematics. Compared with A-level students, B-level students have weaker classroom response and ability to accept, especially poor self-confidence. They do not like to raise their hands to answer questions and have low enthusiasm for participation in the teaching process.
