课堂练习题是对课本知识和课后练习的补充与加深,都是教师针对课本知识特意准备的,目的性强,旨在提高学生的解题能力。在解题过程中,学生一般都会采用课本中的方法解题,这虽然加深了对课本知识的了解,但也限制了自己的解题思路。因此,教师在设置课堂练习题时要注意到解法的多样性,这样学生才会给予意想之外的回应。1问题背景例题:(浙江教育出版社《数学》第三册(中专) Classroom exercises are supplementary and deepening of textbook knowledge and after-class exercises. They are specially prepared for teachers and are purposeful and designed to improve students’ ability to solve problems. In the process of solving problems, students generally use the methods in textbooks to solve problems. Although this deepens the understanding of textbook knowledge, it also limits their own problem-solving ideas. Therefore, teachers should pay attention to the diversity of the solution when setting up classroom exercises, so that students will give extra-ideal responses. 1 Problem Background Example: (Mathematics, Vol.3, Zhejiang Education Press)
