观察和实验,能够使学生对物理知识获得较为直观的认识;观察和实验,能够培养学生的观察和实验能力,同时,也能够培养学生实事求是的科学态度,激发学生学习的兴趣。在初中物理教材中,增加了一些课后小实验。这些小实验有的侧重于操作、有的侧重于设计、有的侧重于对物理知识的理解和应用,各有特点和作用,是课堂教学的延伸和补充,是搞好物理实验教学的不可忽视的重要组成部分。而对于这些小实验,许多教 Observation and experiment can enable students to gain more intuitive understanding of physical knowledge. Observation and experiment can cultivate students' ability of observation and experiment. At the same time, they can also cultivate students' realistic and scientific attitude and stimulate students' interest in learning. In junior high school physics textbooks, add some small experiments after class. Some of these small experiments focused on the operation, some focused on the design, and some focused on the understanding and application of physical knowledge, each with its own characteristics and functions, is an extension and complement of classroom teaching is to improve the teaching of physics experiments can not be ignored important parts of. And for these little experiments, much teaching
