在数学教学中.精心创设教学情境.能够调动学生的学习积极性.下面举例谈谈我的一点尝试.一、设置疑问判定两个三角形相似有许多方法.其中“预备定理”是最基础也是最重要的定理之一.学好“预备定理”对学生学习其他判定方法非常重要.在复习课时.我精心创设情 In mathematics teaching, carefully creating teaching situations. Can mobilize the students’ enthusiasm for learning. Here are some examples to talk about my attempts. First, set the query to determine the similarity of two triangles There are many ways in which “preparatory theorem ” is the most basic One of the most important theorems. It is very important for students to learn other “judgment theories” to learn the “preparatory theorem”. During the review class, I carefully created the situation.
