一、层次教学,学生的实践与抽象的理论相结合小学生的思维处于直观形象思维为主,并逐渐向抽象思维过度。在“平面图形”的教学中,应着重强调让学生的直观体验用动手操作的方式呈现出来,这样就能有效地将外显性的活动与内隐性的活动结合起来。因此在一节课堂不同的教学阶段,要尽可能地为学生提供与教学内容相对应的操作机会。例如,在教学《角的认识》的过程中,先根据认识角的特征后学生画一个角,然后用两根小棒夹成一个角,最后让学生随意拉小棒形成不同的夹角,体验到角的大小与边的关系。整个教学过程中,一步比一步抽象,但学生
First, the level of teaching, the practice of students and the combination of abstract theory of primary school students thinking is intuitive visual thinking-based, and gradually to the abstract thinking over. In the teaching of “Plane Graphics”, it should be emphasized that the intuitive experience of the students should be presented in a hands-on manner, so that explicit and explicit activities can be effectively combined. Therefore, in a different classroom teaching stage, as far as possible to provide students with teaching content corresponding to the operating opportunities. For example, in the teaching of “knowledge of the corner”, students first draw a corner according to the characteristics of the corner of view and then use two small sticks to form a corner. Finally, students are allowed to pull small sticks to form different angles and experience The size of the corner and the relationship between the edge. Throughout the teaching process, abstract step by step, but students
