初中数学课堂的变式教学已经有多年的利用,现在也已经被广大教师所接受,但是实践的教学效果却不明显.当前如何更好地发挥变式教学的应有效果是广大初中数学教师需要研究的重要课题.本文笔者结合多年教学实践,首先分析传统教学模式同变式教学差异,其次结合教学实例就初中数学课堂的变式教学措施展开探讨,以期抛砖引玉.变式教学指的是在保持数学题本质特征不再变化的情况下,从不同的角度来改变数学问题的呈现方式,进而引导学生
The variant teaching of junior high school mathematics classroom has been used for many years and now it has been accepted by the majority of teachers, but the teaching effect of practice is not obvious. How to give full play to the proper effect of variant teaching is the need of junior high school mathematics teachers The author of this dissertation analyzes the difference between the traditional teaching model and the variant teaching, and then discusses the variant teaching methods of the junior middle school mathematics classroom with the teaching examples in order to start a discussion on the teaching reform. Under the circumstance that the essence of math problem is no longer changing, the way of presentation of math problems is changed from different perspectives to guide the students
