关于在平几教学中培养学生的解题能力问题,笔者有以下三点基本看法: 1.在平面几何教学中,学生解题能力的培养是学生能力培养的一个主要方面; 2.从当前的教学现状来看,学生学习平面几何的困难主要是“课上听得懂,题目不会做”,培养学生解题能力十分必要,教师应通过教学使学生解题时“思考有路,解题有方”,防止和克服解题中“盲人骑瞎马”的倾向。 3.培养学生的解题能力,在做法上要教给学生以“点石成金”的手指,古人说:“授人以鱼,不如教人以渔(指捕鱼的方法”),因而培养解题能力应把重点放在“教思路、教方法”上。以下试从四个方面谈谈
With regard to the problem of cultivating students’ problem-solving abilities in the teaching of Ping-Jian, the author has the following three basic observations: 1. In the teaching of plane geometry, the cultivation of student’s problem-solving abilities is a major aspect of student’s ability cultivation; 2. From the current According to the status quo of teaching, students’ difficulty in learning plane geometry is mainly “understand in class and the topic will not be done”. It is very necessary to cultivate students’ problem-solving abilities. Teachers should solve problems by teaching. “Thinking has a way to solve problems. Have a square ”to prevent and overcome the tendency of “blind people ride horses” in the solution. 3. Cultivate students’ problem-solving abilities. In practice, students should be taught to use “finish a stone” finger. The ancients said: “To teach people to fish is better to teach people to fish (refers to the method of fishing). The ability to solve problems should focus on “teaching ideas and teaching methods.” The following test talks from four aspects
