物理学是建筑在实验基础上的一门科学。在中学物理教学中建立物理概念、物理规律,应用物理知识和提高物理教学质量,离开实验也是难以实现的。中学物理实验又是学生今后从事物理实验和科学实验的起点。因此,探索中学物理实验能力的内容并切实加以培养,是中学物理教学的一项重要任务。一观察能力是中学物理实验能力中的基础能力。培养学生的观察能力,在教师进行演示实验时,要引导学生进行有目的的重点观察。做演示实验时,除交代实验器材、实验目的外,更要提出观察的重点。例如,初中教学机械能的转化与守恒的课题时,要演示滚摆的实验,这个实验的观察重点,应是重
Physics is a science based on experiments. Establishing physical concepts, physical laws, applying physics knowledge, and improving the quality of physics teaching in middle school physics teaching are also difficult to achieve without the experiment. The middle school physics experiment is also the starting point for students to engage in physical experiments and scientific experiments in the future. Therefore, it is an important task for middle school physics teaching to explore the content of middle school physics experiment ability and to practically cultivate it. An observation ability is the basic ability in middle school physics experiment ability. Develop students’ observation skills. When teachers conduct demonstration experiments, they must guide students to carry out focused observations. When doing demonstration experiments, it is necessary to put forward the focus of observation, in addition to the laboratory equipment and experimental purposes. For example, when junior high school teaches the transformation and conservation of mechanical energy, it is necessary to demonstrate the experiment of rolling. The focus of this experiment should be emphasis.
