一次会议上,一位中学物理教研员谈到了高中物理新课程实验教学的显著变化:原来只要求学生做10个实验,现在增加到了22个;现在几乎每一节课都要求学生能从实验中感知物理知识和物理规律。这无疑是个令人欣喜的变化。这一变化也更符合物理学科的学习特点。首先,物理是一门实验学科,实验在学习过程中占有重要地位。其次,从大量的实验中认识物理现象、知识和规律,这符 At a conference, a physics teacher at a middle school talked about the remarkable changes in experimental teaching of the new high school physics curriculum: originally, only 10 experiments were required for the students and now the number increased to 22. Now almost every class requires students to experiment Perception of physical knowledge and physical laws. This is undoubtedly a welcome change. This change is more in line with the learning characteristics of physics. First of all, physics is an experimental discipline, and experiments play an important role in the learning process. Second, recognizing physical phenomena, knowledge and laws from a large number of experiments, this symbol
