论文部分内容阅读
本节内容是从动力学角度来研究行星运动的,研究过程是依据已有规律进行的演绎推理过程。教学内容中涉及了处理物理问题的简化思想和科学探究的逻辑思考。值得一提的是本节课本内容引力公式推导上不是很严密,逻辑性不强,值得老师深入处理教材内容.通过对教材上逻辑思维推导的改进,让学生以自己现有的知识基础身于历史的背景下,经历一次“发现”万有引力的过程,因此体验物理学研究问题的方法就成为本节内容主要的教学目标。
The content of this section is to study planetary motion from a kinetic point of view. The research process is a deductive reasoning process based on the existing laws. Teaching content involves dealing with the simplified thinking of physical problems and logical thinking of scientific inquiry. It is worth mentioning that this section of the textbook gravity formula is not very tight on the derivation, the logic is not strong, it is worth the teacher in-depth processing of teaching materials.By the logical derivation of the textbook on the improvement, so that students with their existing knowledge base in Under the background of history, through the process of “discover ” gravitation, the method of experiencing the problem of physics research becomes the main teaching goal in this section.
