中学的物理教学中开展实验演示教学是十分重要,也是非常必要的。因为课堂上的实验演示不但可以引起学生的兴趣,调动学生的学习积极性,而且有助于学生对知识的深度理解。观察与实验是初中学生掌握物理概念和规律的重要前提,是学生获得具体的、感性的认知的主要手段,同时还是学生们提高物理学习效率的重要方法。但是现实物理教学中并没能重视实验演示部分,很大程度地降低了学生学习兴趣,所以初中物理老师以及物理教学界应该高度重视实验演示教学的发展。
It is very important and necessary to carry out experimental demonstration teaching in physics teaching in middle school. Because the experimental demonstration in the classroom can not only arouse the interest of students, arouse the enthusiasm of students to learn, but also help students to understand the depth of knowledge. Observation and experiment are important preconditions for junior middle school students to master the concepts and laws of physics. They are the main means for students to acquire concrete and perceptual knowledge. They are also an important method for students to improve the efficiency of physics study. However, the actual physics teaching did not attach importance to the experimental demonstration part, greatly reduced the students’ interest in learning, so junior high school physics teachers and physics teaching should attach great importance to the development of experimental demonstration teaching.
