物理是一门以实验为基础的学科,搞好物理实验教学有助于学生形成正确的物理概念,加深对物理规律的理解,增强观察和分析物理现象的能力。同时中学物理大纲也明确规定了实验教学的任务,并把培养学生的实验技能作为中学物理教学目的之一。然而在物理常规教学中极为普遍存在着将实验课安排在所授新课后进行,作为对课本有关内容的验证,这样做既浪费了课时,也不利于学生智力的发展和能力的培养。为此我们在进行物理理论教 Physics is an experiment-based discipline. Doing a good job in physics experiment teaching helps students form the correct physical concepts, deepen their understanding of physical laws, and enhance their ability to observe and analyze physical phenomena. At the same time, the middle school physics syllabus also clearly stipulates the task of experimental teaching, and cultivating the students’ experimental skills as one of the purposes of physics teaching in middle schools. However, it is very common in physics routine teaching that experiment classes are arranged after the new class is taught as a verification of the content of the textbook. This is not only wasted hours but also is not conducive to the development of students’ intelligence and the cultivation of their abilities. For this reason we are teaching physical theory
