本人最近看了《数学通讯》2009年第11期中的一篇文章,题目是《例谈高中数学变式教学的有效性》,写得非常好,文中突出了以“教师为主导,学生为主体”的理念,即所有的变式都是由教师事先设计好,然后学生思考分析,老师讲解,这种模式固然能够提高课堂教学效果,但这其中是不是显示出我们教师很强势,很霸道,显示出学生很无奈,很被动,使学生无从知道变式的来龙去脉,从而也失去了探究这一非常重要
I recently read an article in Mathematics Communication, No. 11, 2009 titled “Effectiveness of Variant Teaching in Senior High School” and wrote very well. The paper highlighted that “teachers are the mainstay and students are Main ”concept, that is, all the variants are designed by teachers in advance, and then students think and analyze, the teacher explained that although this model can improve the effectiveness of classroom teaching, but which one is not very strong that our teachers are very Overbearing, showing that students are helpless, very passive, so that students have no way to know the context of variants, which also lost the very important to explore
