“阿基米德原理”是教师开展公开课、比武课、研究课的热门课题。笔者有幸承担此课题的研究课,在分析教材的过程中,我觉得新旧教材在实验的编排上都是以验证性实验的模式出现,比如:新教材第一句话是“浸入液体中的物体受到的浮力有多大呢?”(提出问题),紧接着推出实验(验证物体受到的浮力跟它排开液体受到的重力相等),最后形成结论(阿基米德原 “Archimedes principle ” is a hot topic for teachers to carry out open class, martial arts class, research class. I was fortunate to undertake this subject research course, in the process of analyzing textbooks, I think the new and old textbooks in the experimental arrangement are based on the experimental mode of verification, such as: new textbook first sentence is What is the buoyancy force on the object? "(Asking a question), followed by an experiment (verifying that the object receives the same buoyancy as the gravitational force it exits the liquid) and finally concludes (Archimedes
