本文拟就初中物理的学习特点,结合自己的教学实践,谈谈初中物理的记亿方法。一、突出重点记忆法初中物理中的概念、规律有些很平淡、较简单;有些非常抽象、复杂,如不注意方法,都不容易记忆。譬如:“力”的概念,是物体对物体的作用,好像很简单,学生往往不求甚解,记得不牢固。教师在讲授力的概念时,应抓住“两个物体”。强调两个物体又有区别;一“施”(施力物体)、一“受”(受力物体)。这样讲授,给学生的印象就深,便于学生记忆。再如讲述帕斯卡定律时,应注意突出“加”、“密闭”、“大小不变”、“向各个方向”这些词。重点讲述这些词的含义,帮助学生理解、掌握。对于初中物理概念、规律的教学,教师应逐步引导学生学会抓关键字眼,了解其含义,突出其重点,这样学生就能记得牢。
This article plans to discuss the characteristics of junior high school physics, combined with their own teaching practice, to talk about junior middle school physics of the way. First, highlight the concept of the key memory method in junior high school physics, the law is somewhat plain, relatively simple; some very abstract, complex, if not pay attention to methods, are not easy to remember. For example: The concept of “force” is the effect of an object on an object. It seems to be very simple. Students often do not seek explanations, and they do not remember it firmly. When teachers are teaching the concept of force, they should seize “two objects.” Emphasize that there are differences between two objects; a “apply” (force object), a“ accept (stress object). Teaching in this way gives students a deep impression and is easy for students to remember. Another example is Pascal’s law. Attention should be paid to the words ”plus,“ ”closed,“ ”invariable size,“ and ”in all directions." Focus on the meaning of these words to help students understand and master. For junior middle school physics concepts and regular teaching, teachers should gradually guide students to learn to grasp key words, understand their meanings, and highlight their key points so that students can remember the prison.
