初中物理“浮力”一章综合了密度、压强和力、力的平衡等相关知识,学习难度感觉不是很大,但学生应用浮力知识分析和解决浮力问题却感觉难度很大。对此,笔者根据自己的教学经验,在引导学生“巧妙利用物体的浮沉条件分析浮力问题”中取得了较好的效果,并逐步把它上升为一种解题思想。 Junior Physics “Buoyancy” chapter combines density, pressure and force, balance of force and other related knowledge, learning experience is not very difficult, but students use buoyancy knowledge to analyze and solve the problem of buoyancy but it is very difficult. In this regard, the author based on their own teaching experience, to guide students “clever use of object floating buoyancy analysis buoyancy problem ” has achieved good results, and gradually it up to a problem-solving ideas.
