同伴教学法是一种在世界各地被广大教师进行尝试的一种教学方法。不同于传统教学对课本知识和讲义中各个层次和细节的介绍，它由许多关键知识点的简短讲授和学生分组讨论概念测试题构成。从教学理论层面上看，这种教学模式的理论支撑是合作学习理论；从实践层面上看，将这种教学方法与传统的概念教学方法实践应用上进行对比是一个有益的尝试，也较为遵从学生的认知规律，符合我国新课程标准改革的精神。在实施过程中，首先从学生的个体发展来看，对物理概念更深刻的理解可以促使他们产生更多的思考问题的方法、更高层次的推理、更广阔的知识迁移；其次，在实施同伴教学法的过程中，也给了物理教师一个机会，能更深入的、从另一方面了解中学生对物理概念的认知过程和认知途径。我国的一些高校和中学已经有在概念教学中使用同伴教学方法的经验。高中物理教学与大学本科的物理教学有内容和形式上的不同，在这个领域，如何实施同伴教学法？如果面对的学生是一个相对优秀的群体，尝试概念教学中的同伴教学模式具有一定的基础。选择《电磁感应》一章为实验的章节，希望能对整章的概念教学提供一些有价值的研究。研究结果主要有：1、研究对象前后测的结果说明在《电磁感应》一章的概念教学中，同伴教学法优于传统教学法；2、在课堂教学中实施同伴教学法，能有效的激励学生，改善学生的学习态度。

Peer Instruction (PI) is a kind of teaching methods used by teachers all over the world. Unlike traditional teaching introduction to the knowledge and lectures of various levels and details, PI consists of key knowledge points, short lectures and concept discussion.From theoretical point of view, the theoretical basis of teaching model is the cooperative learning theory; from practical point of view, comparison of PI and traditional teaching method is not only a good project, but also comply with students' cognitive rules and the new spirit of curriculum reformFirst, in order to provide students perspective of individual development, a deeper understanding of physical concepts can encourage them to figure out more thinking approach, a higher level of reasoning, and the wider knowledge transfer.Secondly, during the implementation process of peer instruction, physics teacher also has an opportunity to understand PI deeply, and understanding cognitive processes and cognitive approach of high school students in learning physical concepts.Some of universities and secondary schools has had experience to use the concept of peer instruction combined with traditional teaching methods. There are many differences between undergraduate and high school in terms of physical education content and form. How to implement peer instruction? If the student have good background, peer instruction will have a good start. Selecting "electromagnetic induction" chapter as experimental content, I hope to provide some valuable research result to the peer instruction. The results are:1.The result measured before and after the study demonstrates that peer instruction is superior to traditional teaching method2.Taking advantage of peer instruction in the classroom, I recognize the magic of interactive and lively teaching methodology.
