物理学是一门以实验为基础的科学,实验教学是物理教学的重要形式,直观、清晰、准确、简洁的实验,有利于学生对学习内容的感知、理解及新知识的生成。反之,实验现象不明显、不成功就会严重影响学生对所学知识的信任,并对老师所讲问题形成质疑,严重影响课堂教学效率。所以,在物理实验教学中,教师对课本上所给实验不能简单模仿,应认真备好实验,才能取得理想的效果。笔者在实验教学中就遇到一例,希望与同行们分享,也期待赐教。
Physics is an experiment-based science. Experimental teaching is an important form of physics teaching. Intuitive, clear, accurate and concise experiments are conducive to students’ perception and understanding of learning content and generation of new knowledge. On the contrary, the experimental phenomenon is not obvious, unsuccessful will seriously affect students’ confidence in the knowledge they have learned, and question the teacher’s question, seriously affecting the efficiency of classroom teaching. Therefore, in the physics experiment teaching, the teacher can not simply imitate the experiment given to the textbook, we should prepare the experiment carefully so as to achieve the desired result. I encountered in experimental teaching an example, I hope to share with colleagues, but also look forward to enlighten me.
