数学教学中,设置课内外练习题是检查学生巩固知识的一种方式,通过课堂练习题,使学生更好地掌握基础知识并获得解题的技能和技巧.那么如何在不同的习题课中恰当选择好题是中学数学教学的一个重要环节.习题课既是教师对学生独立思考活动的指导过程,也是学生学会运用所学基础知识,加强基本技能,基本训练的必由之路,又是为实现教会学生怎样解题而采用的一种教学方法.在习题课教学中,教师既要选择典型例题讲解示范,又要选择习题供学生练习,然而课堂时间有限,因而确定习题课型与选择习 In maths teaching, setting up extracurricular exercises is a way to check the students’ knowledge and consolidate their knowledge. Through the exercises in the classroom, students can better grasp the basic knowledge and acquire the skills and skills of solving problems. So how to be appropriate in different exercises Choosing a good topic is an important part of middle school mathematics teaching.Exercise class is not only the guiding process of teachers’ independent thinking for students, but also the necessary way for students to learn basic knowledge, strengthen basic skills and basic training, Problem-solving and a teaching method used in the teaching of exercises, teachers should not only choose a typical example to explain the model, but also to select exercises for students to practice, but the classroom time is limited, and thus determine the exercises and choice of exercise
