在初中数学教学中开展变式教学,能调动学生的学习兴趣,培养学生的逻辑思维能力,提高课堂教学效果.下面结合自己的教学实践就初中数学教学中例、习题的变式及重组谈点体会.一、概念性变式教学概念变式,即对概念进行多方位的分析理解,利用更加直观的变式介绍概念.初中学生知识体系的建立过程,最重要的就是初期阶段,但是在现有的数学教材中,有很多概念知识都非常抽象,概括性比较强.因此,在概念教学中,教师要利用概念变 In the junior high school mathematics teaching to carry out the variant teaching, can arouse students ’interest in learning, cultivate students’ logical thinking ability, improve the effect of classroom teaching.Considering their own teaching practice on junior high school mathematics teaching examples, exercises and reshuffle talk First, the concept of variant teaching concept variants, that is, the concept of multi-directional analysis and understanding of the use of more intuitive variants of the concept of the establishment of junior high school students knowledge system, the most important is the initial stage, but now Some mathematics teaching materials, many of the concept of knowledge are very abstract, relatively strong summary.Therefore, in the concept of teaching, teachers should use the concept of change
