初中数学教师在开展教学时,要在对话中引导学生理解数学知识的本色。学生只有把握了数学知识的本色,才能高效地吸收数学知识。一、结合数学知识的抽象性特点开展教学对话部分初中生遇到数学问题的时候,常常找不到解决数学问题的切入点。比如学生遇到几何问题的时候,不能发挥空间想象力解决数学问题;遇到方程问题的时候,不能把方程问题转化为坐标图像,在坐标图像上讨论方程的问题;部分学生谈到初
When junior middle school mathematics teachers conduct teaching, they should guide students in understanding the nature of mathematics knowledge in the dialogue. Only by grasping the true nature of mathematics can students absorb mathematics knowledge efficiently. I. Combining the abstract features of mathematics knowledge When conducting junior middle school students in teaching dialogues, they often cannot find the starting point for solving mathematical problems. For example, when a student encounters a geometry problem, he cannot use space imagination to solve math problems. When he encounters an equation problem, he cannot convert the equation problem into a coordinate image. Discuss the problem of the equation on the coordinate image. Some students talk about the beginning of the equation.
