著名物理学家爱因斯坦说“兴趣是最好的老师”。兴趣是学习最好的老师,而学生的学习兴趣不是天生的,主要在于教师如何引导学生,充分调动学生对学习的积极性和主动性,进而能创造性地学习,最终达到优化课堂教学和提高教学效率的目的。初中生有较强的好奇心,这能激励他们主动地去探索知识。因此,我们物理教师在教学过程中,尤其要注意保护学生的好奇心,激发他们的学习兴趣。有了兴趣,学生不再感到物理学习是很困难的,而觉得物理学习是有趣的,物理知识很有用,是很美 Well-known physicist Einstein said “interest is the best teacher ”. Interest is to learn the best teacher, and students' interest in learning is not born, mainly teachers how to guide students, and fully mobilize the enthusiasm and initiative of students in learning, and thus be able to learn creatively, and ultimately achieve the optimization of classroom teaching and improve teaching efficiency the goal of. Junior high school students have a strong curiosity, which can motivate them to explore knowledge on their own initiative. Therefore, we physical teachers in the teaching process, with particular attention to protecting the curiosity of students, to stimulate their interest in learning. With interest, students no longer feel that physical learning is very difficult, and that physical learning is interesting, physical knowledge is very useful, is very beautiful
