物理学是一门观察和实验为基础的科学。课堂演示实验是建立物理概念、揭示物理规律、理解和掌握物理知识不可缺少的环节,同时还能培养学生的观察能力、思维能力、探索精神以及浓厚的学习兴趣。而现实的物理课堂当中,演示实验的实验现象不清、实验目的不明、实验过程太机械化等问题比较突出。本文将从如何把演示实验变成“魔术表演”的过程以及它的重要性进行全面的分析。
Physics is a science of observation and experiment. Classroom demonstration experiment is the establishment of physical concepts, reveal the laws of physics, understanding and mastering the indispensable part of the physical knowledge, but also to develop students’ observation ability, thinking ability, exploration spirit and strong interest in learning. However, among the realistic physics classrooms, the demonstration of experiment is not clear, the purpose of experiment is unknown, and the experiment is too mechanized. This article will provide a comprehensive analysis of how the demo experiment has become a “magic show” and its importance.
