物理是一门以实验为基础的学科,在初中物理教学中加强实验尤其重要。因此,物理实验不应仅局限于课堂上,在课外练习中也应该包括实验性作业。近两年来,我们除了课内完成演示实验、学生实验以外,还开展了家庭小实验活动。从初中物理教学内容来看,它与日常生活密切相关,结合每部分的教学内容都可以做些家庭小实验;而且家庭中不少的生活用品和废旧物资可以成为很好的实验器材;又由于实验时间不象在学校内受到严格的限制,可以让学生充分地观察和研究。所以说,开展家庭小实验活动有着丰富的内容和充足的条件,而且可以弥补课堂实验中的不足。由于学生的家庭条件不同,各个学生的能 Physics is an experiment-based discipline. It is especially important to strengthen experiments in junior high school physics teaching. Therefore, physics experiments should not be confined to the classroom. Experiments should also be included in extracurricular exercises. In the past two years, apart from completing demonstrations and student experiments in class, we have also conducted small family experiments. Judging from the content of junior high school physics teaching, it is closely related to daily life, and combined with the teaching content of each part can do some home experiments; moreover, many household items and used materials in the family can become very good experimental equipment; The experiment time is not strictly limited as in the school, allowing students to fully observe and study. Therefore, there are abundant contents and sufficient conditions for carrying out small-scale experimental activities in the family, and they can make up for deficiencies in classroom experiments. Due to the different conditions of the students’ families, each student’s ability
