初中作为学生物理学习的起始阶段,培养学生的物理学习兴趣和科学探究意识至关重要。教学不应该仅仅是灌输知识和解答习题的周期性活动,应该把初中物理上出生活味、科学味。笔者在教学实践中发现,“原始物理问题”的教学功能要胜过模型化习题的教学价值。本文以一道“原始力学问题”和一道“原始电学问题”为例进行分析,望对初中物理教学的改革有一定的启发作用。一、一道原始力学问题研究在讲完阿基米德定律以后,笔者引出生活中的一个原始物理问题,引导学生用实验的方式进行自主探究,生成问题并运用阿基米德定律进行分析。1.原始问题有一不大的小水池,一条载满了石块的船浮于水 As the initial stage of students ’physical learning, it is very important to cultivate students’ interest in physics study and scientific inquiry. Teaching should not only be a cyclical activity that instils knowledge and answers to exercises, it should be physically and tastefully scientific in junior high school. The author found in teaching practice that the teaching function of “original physics problem” should outperform the teaching value of model exercises. In this paper, an analysis of “primitive mechanics problems” and “primitive electrical problems” is taken as an example, and it is hoped that it will inspire the reform of physics teaching in junior middle schools. First, a study of the original mechanical problems After the completion of the Archimedes law, the author leads to a primitive physical problems in life, to guide students to conduct their own experiments in an independent way to explore the problem and use Archimedes’ law to analyze. 1.
