对于教学,只有激发了学生的求知欲望和兴趣,引导学生进行探究思考,才能在不断的探索中获取知识。在物理教学中应用对比性实验,可以激发学生的学习兴趣,提高学生发现问题、思考问题和解决生活中遇到实际问题的能力,使学生动手操作的能力以及设计实验的能力得到加强,形成明确的物理概念,加深对物理规律的记忆和理解。因此,对比性实验被越来越多的引进课堂,应用对比性实验来进行教学。 For teaching, only by stimulating students’ desire for knowledge and interest, to guide students to explore thinking, in order to obtain knowledge in continuous exploration. Applying comparative experiments in physics teaching can arouse students ’interest in learning, enhance students’ abilities of finding problems, thinking problems and solving practical problems encountered in their daily lives, enhancing the ability of students to operate hands and designing experiments, The physical concept, deepen the memory of physical laws and understanding. Therefore, comparative experiments are more and more introduced into the classroom, the application of comparative experiments for teaching.
