如何精选习题,加强解法指导,减轻学生过重的负担,提高教学质量,是当前改革数学教学的重要课题。 一、三类习题 人的知识是一步一步地由低级向高级发展的。根据这个认识规律,在学习进程的各个阶段,要由浅入深地编选习题。习题大致可分为三大类: 1.基础题。它是直接应用概念、定理,法则的题目,通常是紧接在教师讲授了新知识后布置的,便于学生理解新概念,掌握新知识,练习新技能。
How to select exercises, strengthen the guidance of solution, reduce the burden on students and improve the quality of teaching is an important issue in the current reform of mathematics teaching. First, the three types of exercises Human knowledge is a step by step from low to high-level development. According to this law of understanding, in all stages of the learning process, it is necessary to make a simple compilation of exercises. Exercises can be broadly divided into three categories: 1. Basic questions. It is the direct application of concepts, theorems, rules of the topic, usually immediately after the teacher taught the new knowledge layout, to facilitate students to understand the new concept, master the new knowledge and practice new skills.
