讲评课在物理教学中是不可缺少的一环.尤其在复习阶段,更显示其重要性.本文就中学物理讲评课的有关问题略加探讨,以期抛砖引玉,引起同行们对这一问题的重视.一、物理讲评课的作用据系统论和信息论的观点,教学过程是一个完整的信息系统.即通过教学活动使学生接受信息;通过学习、巩固,使学生储存信息;通过作业、练习、检测,使学生输出信息;通过讲评反馈信息,以调整教学,继续搞好后段学习.其过程如下图所示:
Lecture class is an indispensable part in physics teaching. Especially in the review stage, it shows its importance. This article will discuss some issues relating to the physics lectures in middle school, in order to attract valuable comments, and attract the attention of peers to this issue. First, the role of physics lectures According to system theory and information theory point of view, the teaching process is a complete information system. That is, through the teaching activities to enable students to accept information; through learning, consolidation, so that students save information; through the operation, practice, testing, Enable students to output information; through feedback on feedback, to adjust teaching, continue to do a good job in the latter part of learning. The process is shown in the following figure:
