在教学过程中发现,有的学生对物理概念的掌握不够深入、不够全面,甚至于只停留在文字和数学表达式的死记硬背中,当碰到考查物理概念的题目时很容易出错.同时,有些物理概念,虽然不属于同一章节或同一知识体系,但在学习中尤其是综合复习中却可放在一起比较着学习,这能使学生对概念的掌握更加全面、透彻.下面举例说明. In the process of teaching, some students find that the concept of physics is not deep enough, not comprehensive enough, and even stay in the memorization of words and mathematical expressions, when faced with the problem of examining the concept of physics is prone to error.At the same time, Although not belonging to the same chapter or the same knowledge system, some of the physical concepts can be put together in study, especially in comprehensive review, which can make students grasp the concept more comprehensively and thoroughly.
