1 实验前的准备、督促、检查 要使学生顺利完成实验任务,达到预期的实验目的,实验前师生都要有充分的准备。多年来,我发现部分学生实验前是不阅读或不认真阅读实验内容的,他们认为分组实验只是重复教师的演示实验而已,不必再花时间去看书。这些学生到实验室后,只能匆忙地赶翻课本,然后“照方抓药”。实验效果如何,是可想 1 Preparation, supervision and inspection before the experiment To enable students to successfully complete the experimental task and achieve the desired experimental purpose, teachers and students must be fully prepared before the experiment. Over the years, I discovered that some students did not read or did not read the experimental content carefully before the experiment. They thought that the grouped experiment only repeated the teacher’s demonstration experiment and did not have to spend time reading. After these students arrived at the laboratory, they could only rush over the textbooks and then “shall catch drugs.” How effective is the experiment?
