目前,一些农村初中,因经费、仪器短缺,物理实验相当簿弱。大纲所规定的演示实验119个,学生实验22个,基本上能完成规定实验的学校只是少数。学生实验更差,多数学校学生动手做实验少,严重地影响教学,不利于人才的培养。近年来,笔者为加强学生分组实验做了点尝试。下面谈点做法和体会。一、充分利用现有设备,大班分小班,轮流做实验,增加学生动手动脑的机会为使每个学生的观察能力和实验技能都得到培养,彻底改变过去那种“一人做大家看,男生做女生看”的学生实验,尽量做到每两人一组。这样,既能人人有动手动脑机
At present, some rural junior high schools are physically weak because of the shortage of funds and equipment. There are 119 demonstration experiments and 22 student experiments prescribed by the outline. There are only a few schools that can basically complete the prescribed experiments. The students’ experiments were even worse. Most students had fewer hands-on experiments and severely affected teaching, which was not conducive to the training of talents. In recent years, the author has made some attempts to strengthen student grouping experiments. Let’s talk about practices and experiences. First, make full use of the existing equipment, large classes in small classes, take turns to do experiments, increase the opportunities for students to use hands-on brains so that each student’s observation ability and experimental skills are cultivated, completely change the past kind of "one person to look at everyone, boys do Girls look at the student’s experiment and try to be a group of two people. In this way, both humans can have manual brain machines
