杠杆平衡是初中简单机械部分的一节,是前边内容的延续,也是后边学习滑轮组、功等的基础,是力学的重点内容之一.一、以现象为出发点我国教育教学中常常把物理学认为是单纯的规律、定义,脱离了它的实质——现象.从认知心理学角度看,大脑并不是一个空白的处理器,只被动接受,它会从感受器接受刺激开始,循序用大脑一步步进行信息处理、并组织相关信息.
Leverage balancing is a section of the simple mechanical part of junior middle school. It is a continuation of the previous content and is also the basis for studying the pulleys, exercises, etc., and is one of the key contents of mechanics. First, taking the phenomenon as a starting point, physics is often considered in education and teaching in China. It is a simple law, definition, and its essence - phenomena. From the perspective of cognitive psychology, the brain is not a blank processor. It is passively accepted. It starts with receptors and starts with the brain. Conduct information processing and organize relevant information.
