浮力这部分内容在初中物理力学部分所占分量较重,既是重点,也是难点。笔者在教学中发现,一些学生对这部分内容中的概念认识比较模糊,理解得不透彻,因此,在教学过程中,笔者借助物理实验,启发、帮助学生加深对重点、难点问题的理解,收到了较好的效果。 Buoyancy in this part of the content of physics in the junior high school part of the heavier weight is not only the key, but also difficult. The author found in teaching, some students in this part of the content of the concept of understanding is rather vague, understanding is not thorough, therefore, in the teaching process, the author with the help of physics experiments to inspire and help students deepen the understanding of key and difficult issues To a better effect.
