我们的经验证明:二人或三人一组作实验(指二人或三人同时使用一套仪器作实验),收效是较差的。上学期末,我们曾举行了一次测验,测验结果,有一部份同学,甚至对简单的物理仪器使用法都不懂。如游标尺及螺旋测微计的读法,有些同学还不会。用温度计读室温时,往往用手拿着水银泡。水银泡外附有水滴(温度计先是插在水杯里的),他们没有考虑到到须要把水擦掉,调整物理天平时,有的不管游码摆在什么地方,有的把游码移到天平臂的中间,称物时把物摆在右盘内,把砝码摆在左盘内。
Our experience shows that two or three people in one group (experimenting with two or three people using a single set of instruments) are ineffective. At the end of the semester, we held a test, the result of the test, and some of our students did not even understand the use of simple physical instruments. Such as the tour guide ruler and spiral micrometer read, some students will not. When reading a room temperature with a thermometer, it is common to hold a mercury bubble in your hand. Mercury bubble attached to the water droplets (thermometer inserted in the glass first), they did not take into account the need to wipe the water, adjust the physical balance, and some no matter where the yards placed in the place, and some movement to the balance Arm in the middle, said the thing placed in the right disc, the weight placed in the left disc.
