一、常见物理解题“数学化”成因分析1.思考问题存在“数学化”思维,物理思维严重缺失案例1:在探究光的反射规律实验中,改变入射光的方向,测得几组入射角和反射角,记录数据如上表.根据实验数据,可以得出结论为____.错误解法:入射角等于反射角.错因分析:学生思考问题时存在“数学化”思维.只注意到表格中数学化的大小关系,而没有认真思考物理量之间的逻辑关系.因为先有入射光,然后才有反射光.因为先有入射角,然后才有反射角.答案:反射角等于入射角.
First, the common matter comprehension question “Mathematics ” causes analysis 1. Thinking problem exists “Mathematics” thinking, serious lack of physical thinking Case 1: In the experiment of exploring the law of light reflection, change the direction of incident light, test There are several sets of incident angles and reflection angles, and the recorded data is shown in the table above. Based on the experimental data, the conclusion can be drawn as ____. Error solution: The incident angle is equal to the reflection angle. Error analysis: When students think about the problem, there is a “mathematicalization.” Thinking. Only notice the mathematical relationship between the size of the table, but did not seriously consider the logical relationship between the physical quantity. Because there is incident light before, then there is reflected light. Because there is an incident angle before, then there is a reflection angle. The reflection angle is equal to the incident angle.
