物理学是一门研究力、热、声、光、电的现象以及原子和原子核运动变化规律的科学。初中二年级学生刚接触到它时感到抽象难懂,这是因为学习物理时,对其中的概念和规律不仅要运用语文知识和数学工具进行描述、表达、推理、论证和变换,而且还要运用科学的实验方法加以证明。万事开头难,难就难在起始学科的“入门”上。为使初中二年级学生尽快适应物理学的学习,现就如何“入门”的问题,谈几点浅见。 Physics is a science that studies the phenomena of force, heat, sound, light, electricity, and the changing laws of atomic and atomic nucleus movements. When junior high school sophomores touch it, they feel abstract and difficult to understand. This is because when they study physics, they not only use the language knowledge and mathematical tools to describe, express, reason, argue, and transform their concepts and laws, but also apply them. Scientific experiments prove it. Everything is difficult at the beginning, and it is difficult to achieve the “entry” of the starting discipline. In order to make secondary school students in junior high schools adapt to physics learning as soon as possible, we now have a few ideas on how to get started.
