在数学教学中,课内外的练习作业是很重要的一个环节。因为数学中的抽象概念和理论比较多,单凭课堂教学中的讲解,不可能就使学生透彻理解和牢固掌握,还必须经过演算和练习,这是其一。其二,学习数学,不仅是掌握概念和理论,还要能够运用学到的知识来解决实际问题,这就需要有熟练的运算技能,而技能技巧是一定要通过反复练习才能获得的。此外数学教
In maths teaching, practicing in and out of class is a very important part. Because there are more abstract concepts and theories in mathematics, it is impossible to make a thorough understanding and a firm grasp of the students through the explanations in the classroom teaching. It is also necessary to go through calculations and exercises. This is one of them. Second, to learn mathematics is not only to master the concepts and theories, but also to apply the learned knowledge to solve practical problems. This requires skillful computing skills, and skills and skills must be obtained through repeated practice. Also math teach
