小学低年级学生具有好动、好玩的特点,思维的发展还处于具体形象向抽象逻辑发展的阶段,为了让学生更好地掌握数学知识点,在课堂中加入动手操作的方式进行教学是必要的。下面我就以两位教师分别执教的人教版小学数学一年级上册《认识立体图形》为例进行研究。一、案例分析对比【案例1】(课前布置学生带积木)师:小朋友,今天这节课你都带了哪些漂亮的积木?(学生汇报)师:你能把这些积木分一分吗?(学生操作)师:谁来说说你是怎么分的?
The students in the lower primary school have the characteristics of being active and playful. The development of thinking is still in the stage of concrete image to the development of abstract logic. In order to enable students to master the knowledge of mathematics better, it is necessary to join hands-on teaching in the classroom . Now I will take two teachers respectively teach the first edition of the PEP teaching “three-dimensional graphics” as an example to study. First, the case analysis and comparison [Case 1] (pre-class layout of the students with building blocks) Teacher: Children, what are the beautiful blocks you brought in this lesson today? (Student Report) Teacher: Can you separate these blocks? (Student Operation) Teacher: Who will tell you how you divided it?
