在中学物理教学中有效实验能够起到很好的作用,能够起到激发学习兴趣,创设情境,养成科学态度;能够优化物理概念的建立,优化对物理规律的认识,提高和培养各种技能和能力,感受和掌握科学方法.实验作用的有效性特征是,学生思维活动的积极参与,实现实验中的一个或多个作用,即实现知识与技能、过程与方法、情感态度价值观三维目标中的一个或多个,同时有利于其他主体知识的落实.提高课堂教学中实验的有效性可以从以下几个方面着手,优化改进课堂教学中的实验方案,根据实验需要选择适当现代技术手段,优化实验问题设计的层次性,循序渐进培养学生的实验能力.
Effective experiments in secondary school physics teaching can play a very good role, can play a stimulating interest in learning, creating situations, develop scientific attitude; to optimize the establishment of physical concepts, to optimize the understanding of the laws of physics, improve and develop various skills And ability to feel and master the scientific method.The effectiveness of the experiment is characterized by the active participation of students in thinking activities to achieve one or more of the role of the experiment that is to achieve the three-dimensional goals of knowledge and skills, processes and methods, emotional attitudes and values Of one or more, at the same time is conducive to the implementation of the knowledge of other subjects to improve the effectiveness of the experiment in the classroom teaching can proceed from the following aspects, optimizing and improving the experimental program in classroom teaching, according to the experimental need to select the appropriate modern technology, optimization The level of the design of experimental problems, gradual development of students’ experimental ability.
