数学科的特点是:知识面广量大,内容十分繁杂。要让学生在短短的两、三个月的时间内,把三年所学的初中数学六册教材,系统地有效地复习一遍,编写一定量的练习题是十分必要的。但这些练习题一定要经过认真的筛选和精心的设计,不仅要具有概念性、代表性、典型性、针对性、综合性,而且要具有启发性、思考性、灵活性、创造性等特点,使之具有较强的指导作用,从而促使学生思维发展,圆满地全面完成教学大纲所提出的教学任务。
The characteristics of the mathematics department are: a wide range of knowledge, and the content is very complicated. It is necessary for students to systematically and effectively review six textbooks of junior high school mathematics that they have studied for three years in a short period of two or three months. It is necessary to write a certain number of exercises. However, these practice questions must be carefully screened and carefully designed. Not only should they be conceptual, representative, typical, pertinent, and comprehensive, but also they should be inspiring, reflective, flexible, and creative. It has a strong guiding role, so as to promote the development of students’ thinking and successfully complete the teaching tasks proposed by the syllabus.
