实验在物理教学中占有非常重要的地位,演示实验是教师随堂做的实验,效果好坏直接关系到结论的得出和课堂的进度。“边教学边实验”可以克服“教师做实验、学生看实验”的弊端。当然,“边教学边实验”对教师备课、准备仪器、组织课堂教学有了更高的要求,只有周密细致的准备,才能取得良好的实验效果。 Experiments occupy a very important position in physics teaching. The demonstration experiment is an experiment done by the teachers at any given time. The result is directly related to the conclusion of the conclusion and the progress of the class. “While teaching experiment ” can overcome “teachers do experiment, students see experiment ” malpractice. Of course, “teaching while experimenting ” has higher requirements for teacher preparing lessons, preparing instruments and organizing classroom teaching. Only careful and meticulous preparation can achieve good experimental results.
