基于学生理解情况研究的浮力教学设计

The Teaching Design of Buoyancy Based on the Studies of Students' Understanding

以问卷调查的形式对当前中学生课前对"浮力"理解情况进行调查。通过调查和研究得到以下结论:初中生认为影响浮力大小的因素中,体积、重量、深度、受力面积、质量、摆放方式所占的比例比较大。据此对"浮力"这一章节的教学设计提出建议。

There is a survey of the current high school students＇ understanding on the ＂buoyancy＂ before class by the way of questionnaire survey. The conclusion by this survey is as follow： students of junior high school always think that volume, weight, depth, force size, quality, display take a relatively large proportion in all of the factors which can affect buoyancy. Accordingly, some recommendations to the design of the teaching of the section of ＂buoyancy＂ are advanced in this thesis.
