初学浮力,学生对阿基米德原理的应用不能深刻理解,因此,在具体问题中利用联想法简化问题,分步、分问题解决,无疑对学生的认识理解有帮助作用。本文借助一道典型的物理题,联想简化模型,层层深入,从理论推导和理论分析两方面对比印证,加深对阿基米德原理的理解,同时也为学生的学习提供一种思路。 Beginning buoyancy, the students can not profoundly understand the application of the Archimedes principle. Therefore, using the method of association to simplify problems, step by step, and solve problems in specific problems will undoubtedly help students' understanding and understanding. In this paper, with a typical physical problem, Lenovo simplifies the model and goes deep into layers. It contrasts and confirms the two aspects of theoretical and theoretical analysis, deepens the understanding of Archimedes 'principle, and also provides a way of thinking for students' learning.
