新课程标准把培养和发展学生的数学思维,激发学生学习数学的兴趣作为重要目标.实践告诉我们,适当的变式训练有助于培养数学思维,激发学生的兴趣.传统的填鸭式教学不仅不能培养数学思维,而且让更多的学生厌恶数学、恐惧数学.那么什么是变式训练呢?变式训练就是在数学学习过程中对概念、性质、定理、公式,以及提问的方式做出适当的变化.有目的、有计划地改变命题中的非本质特征,变换问题中的条件或结论,转换问题的内容和形式,配置实际应用的各种环境.但应
The new curriculum standards to train and develop students ’mathematical thinking, to stimulate students interest in learning mathematics as an important goal.Practice tells us that the appropriate variant training helps to develop mathematical thinking and stimulate students’ interest.Traditional spoon-fed teaching not only can not Develop mathematical thinking, but also make more students dislike mathematics, fear of mathematics. So what is variant training? Variant training is in mathematics learning process on the concept, nature, theorems, formulas, and questions to make the appropriate To change the non-essential characteristics of the proposition in a purposive and planned manner, to change the conditions or conclusions in the problem, to change the content and form of the problem and to configure the various environments for practical application.
