练习是一种有目的、有计划、有步骤、有指导的教学训练活动,是学生掌握知识、形成技能、发展智力、培养能力、养成良好学习习惯的重要途径;也是教师掌握教学情况,进行反馈调节的重要措施。因此,我们在设计练习的时候,要认真钻研教材,理解编排意图,根据教材提供的内容、班级的不同、学生知识水平的差异,对教材里习题作适当调整、组合、补充,使之能从质与量两个方面适应不同程度学生学习的需要。也是提高数学课堂教学质量的需要。传统的教学中,老师讲得多,学生练得少,课内不足课后补,造成 Practice is a purposeful, planned, step-by-step instructional training activity. It is an important way for students to master knowledge, form skills, develop their intelligence, develop their abilities, and develop good study habits. It is also an important way for teachers to master their teaching and conduct Feedback regulation of important measures. Therefore, we should conscientiously study the textbooks and understand the layout intent according to the contents provided by the textbooks, the different classes and the differences in the students’ knowledge levels. We should make appropriate adjustments, combinations and supplements to the exercises in the textbooks to make them from Quality and quantity to adapt to different levels of student learning needs. It is also necessary to improve the quality of mathematics classroom teaching. In the traditional teaching, the teacher speaks a lot, the student practice is less, the class is insufficient after the class completes, causes
