《浮力》是初二物理教材的重点,学生学习过程中,觉得内容抽象,不能把所学知识用于解决实际问题,面对浮力综合习题,不知从那人手,与学生交谈,发现学生没有掌握合适的解题程序和正确理解题意.如何解答好浮力综合题呢?总结学生做题实践,归纳如下:1.明确被研究的对象处于什么样的状态中,如物体在液体中是漂浮、悬浮,还是沉底,上浮还是下沉.要正确理解关键词,如“浸入”、“露出”、“浮
Buoyancy is the focus of the second physics textbook. During the student’s learning process, I feel that the content is abstract and cannot be used to solve practical problems. In the face of buoyant exercises, I don’t know from the manpower, I talked with the students and found that the students did not master. Appropriate problem solving procedures and correct understanding of the meaning of the problem. How to solve a good buoyancy problem? Summarize the students to do the practice, summed up as follows: 1. Clearly what kind of state of the object being studied, such as the object is floating in the liquid, Suspended, or sinking, floating or sinking. To correctly understand keywords, such as ”immersed in“, ”exposed“, ”floating"
