《物理课程标准》要求,在突出科学探究内容的同时,重视研究方法的指导,使学生在进行科学探究、学习物理知识的过程中,逐渐拓宽视野,初步领悟到科学研究方法的真谛.因此,必须重视物理教学中蕴含的大量的科学方法,把它们渗透到教学活动中去,适时向学生介绍、点拨,让学生在学习活动中去体验、体会科学方法,逐步提高学生科学探究能力十分重要.在初中阶段转换法就是需要掌握的重要 The “Physical Curriculum Standard” requires that while emphasizing the content of scientific inquiry, the guidance of research methods should be emphasized so that students gradually broaden their horizons and understand the true meaning of scientific research methods during the process of scientific inquiry and study of physical knowledge. Therefore, We must attach importance to a large number of scientific methods contained in physics teaching, infiltrating them into teaching activities, introducing students to them in time and making suggestions. It is very important for students to experience in learning activities, understand scientific methods and gradually improve their scientific inquiry ability. In the junior high school transition method is the need to grasp the important
