物理教学中的演示实验,无论是展示现象、导出概念还是发现规律,都有着其他教学方式不可替代的作用。通过演示实验,能够为学生提供丰富的感性材料,使抽象枯燥的知识变得形象生动。既可以激发起学生学习物理的兴趣,调动学生学习的积极性、主动性,提高课堂教学效率,又可以培养学生的实验技能、操作技能,更重要的是有利于使学生形成严谨的、实事求是的科学态度。现就初中物理演示实验教学谈谈粗浅的看法。一、初中生的心理特点和物理学科特点要求必须加强演示实验教学
The demonstration experiment in physics teaching, whether it is presenting phenomena, deriving concepts or discovering laws, has the irreplaceable role of other teaching methods. Through demonstration experiments, students can be provided with a wealth of sensuous materials, making abstract and boring knowledge vivid. It not only arouses students ’interest in studying physics, arouse the enthusiasm and initiative of students in learning, improve the efficiency of classroom teaching, but also can train students’ experimental skills and operation skills. More importantly, it helps students to form a rigorous and realistic science attitude. Now junior high school physics demonstration experiment teaching to talk about the superficial view. First, the psychological characteristics and physics characteristics of junior high school students must strengthen the demonstration experiment teaching
