在物理学习中,有时为了实验结论的顺利得出,有时为了突出实验现象,在实施过程中,常常要采用一些特殊的研究方法指导学生学习,使学生轻松地对课本知识进行理解与掌握,并将所学的物理知识应用于学习和生活中去.第一种方法也是用的最为普遍的方法要数控制变量法.物理教材中许多物理量的大小是由多个因素决定的.对于多因素问题的研究,必须采用控制因素(变量)的办法,把 Sometimes in order to highlight the experimental phenomena, some special research methods are often used to guide students’ learning so that students can easily understand and master the knowledge of textbooks The knowledge of physics used in learning and life to go.The first method is also the most common method to control the number of variables.Physical teaching materials in many physical size is determined by a number of factors.For the multi-factor problem The research must adopt the control factor (variable) approach to put
