物理是以实验为基础发展起来的学科,物理实验在物理教学中具有独特的作用。正如有人所说:对于实验,无论怎么强调都不算过分。”作为物理教师、在课堂教学中成功地运用物理实验,可以加强学生的感知,启发学生的思维,从而提高教学效果。科学实验是学习知识的基础,是获得知识的源泉。在教学中运用演示实验能起到“百闻不如一见”的作用。演示实验的作用主要表现为以下几方面: (1)为学生掌握基本概念、基本原理提供丰富的感性材料。通过观察和实验活动,能使学生的感性认识和理性认识相联系,印象直观,容易理解。 (2)能够引导学生从实际出发,实事求是地分析问题,学会由表及里,由现象到本质,全面地辩证地
Physics is a subject developed on the basis of experiments. Physical experiments have a unique role in physics teaching. As someone said: For the experiment, no matter how emphasized are not excessive. As a physical teacher, successfully using physics experiment in classroom teaching can enhance students 'perception and inspire students' thinking so as to improve teaching effect.Science experiment is the basis of learning knowledge and the source of knowledge.Demonstration in teaching Experiments can play the role of “one-of-a-kind experience” demonstration of the role of the experiment mainly in the following areas: (1) for students to master the basic concepts, basic principles provide a wealth of perceptual material through observation and experimental activities, Students' perceptual knowledge is related to rational cognition, and they are intuitive and easy to understand. (2) Students can be guided to analyze facts from facts and facts, to learn from the inside and outside, from phenomena to essence, and comprehensively and dialectically
