物理是一门实验的科学,物理知识中的许多概念、规律都来自于实验,所以初中物理教学要从实验出发。如实验装置的安装、实验步骤的安排、实验现象的观察和分析、实验数据的读取、实验误差的分析等是学生完成实验的一个个重要环节,这些环节的变化是改善实验教学的方向。实验作为教学方法的一种基本构成因素,是学习物理的基本方法。通过实验培养学生的观察能力、 Physics is an experimental science. Many concepts and laws in physics knowledge come from experiments, so junior high school physics teaching should start from experiments. Such as the installation of experimental devices, the arrangement of experimental procedures, the observation and analysis of experimental phenomena, the reading of experimental data, and the analysis of experimental errors are all important parts of a student’s completion of experiments. The changes in these aspects are the directions for improving experimental teaching. Experiments as a basic component of teaching methods are the basic methods for learning physics. Through experiments to develop students’ observation skills,
