在数学教学中,抓好概念教学是取得教学成功的关键一步,下面谈谈我在教“点的轨迹”一节时的一些做法与体会.“轨迹”一词学生比较陌生,教材所下的定义也比较抽象、难懂.为了使学生更好地掌握“轨迹”这个概念,我尽量勾通语文、教学两门学科间的横向联系.联系学生学过的语文课知识来增加课堂教学的形 In mathematics teaching, grasping the concept teaching is a key step in achieving teaching success. Now I will talk about some of the practices and experiences I have in teaching the “point of locus” section. The word “trajectory” is relatively unfamiliar to the students. The definition is also relatively abstract and difficult to understand. In order to enable students to better grasp the concept of “trajectory”, I try to trace the horizontal relationship between the two disciplines of Chinese and teaching. Connect with students’ knowledge of language classes to increase the shape of classroom teaching.
