新的课程标准要求小学数学课堂教学要以学生的身心发展规律为基础。所以,在日常教学中,教师要引导学生从经验和已有知识出发,把数学问题转化为生活问题,进而分析、解决这一问题,得出数学结论,并进行解释和应用。一、创设操作情境,使学生在动手中解决问题在数学课上,要让学生动手,就要创设操作情境。如,在学习体积和表面积这一节中,教师让学生每人准备一个长方体和正方体纸盒,课上让学生做一个小设计师,先亲自动手量一量这个纸
The new curriculum standards require that primary school mathematics classroom teaching be based on the law of physical and mental development of students. Therefore, in daily teaching, teachers should guide students from the experience and existing knowledge, the mathematical problems into life problems, and then analyze and solve this problem, draw mathematical conclusions, and explain and apply. First, the creation of operational situations, so that students solve the problem in the hands of Mathematics class, let students hands, it is necessary to create operational scenarios. For example, in the section on learning volume and surface area, the teacher asked the students to prepare a box of rectangular parallelepipeds and one for each student. In class, the student should be a small designer.
