在一次课堂教学中,我曾讲过“三角形具有稳定性”这一原理。为了提高这一节课的有效性,我从以下三方面准备并实施了教学情境设计,本节课学生反映出极高的求知欲和理解力,学习效果特别好。一、设计导课情境,引起学生极大的学习兴趣,积极投入其中一堂生动有效的数学课,需要教师精心设计教学的全过程。好的导课内容,可以起到事半功倍的效果。为了上好这节课,我首先 In a class teaching, I have talked about the principle that “the triangle has stability.” In order to improve the effectiveness of this lesson, I prepared and implemented the teaching situation design from the following three aspects. The students in this lesson reflected extremely high curiosity and comprehension, and the learning effect was particularly good. First, the design guide situation, arouse students’ great interest in learning, actively involved in a vivid and effective math class, requires teachers to elaborate the whole process of teaching. Good guide lesson content, can play a multiplier effect. In order to improve this lesson, I first
