学生普遍反映物理难学。原因是多方面的,其中一点就是学习物理知识技能中错误。笔者在“力”的教学中对学生的学习错误进行了一次调查研究得出以下几点。一、不能全面、正确地理解物理概念、物理规律和物理公式1.没有深入理解物理概念的物理意义例如,分析抛向空中的球的受力时,有很多学生分析它受到推力,这说明对力的概念理解时,没有认识到力是不能离开施力物体 Students generally reflect the physical hard to learn. There are many reasons for this. One of the reasons is the mistake in learning physics knowledge and skills. The author of the “force” teaching on student learning errors conducted a survey to study the following points. First, you can not fully and correctly understand the physical concepts, physical laws and physical formulas 1. Physical meaning is not understood in-depth understanding of the physical meaning For example, the analysis of the force thrown on the ball in the sky, many students analyze it by thrust, The concept of force does not recognize that force can not leave the object of force
