【案例】“做实验了,上实验课了,快走啊!快去占地方。”铃声一响,学生像一窝蜂似的挤到了实验室里。由于农村教育设备落后,很多实验器材准备不齐,有很多的实验只能由分组改成了演示,甚至变成了照本空讲,实验显得很空洞无味。学生今天终于盼到了一节实验课,而且是大家都可以参加的分组实验,他们像脱缰的野马一样冲进实验室,如滔滔洪水,拦也拦不住。这也是令我最头疼的地方,每次这么仅有的实验课,学生的声音会永远淹没老师的 [Case] ​​ “Experimenting, experimenting with the class, go faster! Get to the place. ” The bell rang, the students swarm into the lab. Due to the backward educational equipment in rural areas, many experimental equipment is not ready for a long time. Many experiments can only be changed from grouping to demonstration, and even become empty talk. The experiment is empty and tasteless. Today students finally come to an experimental class, and we can all participate in the group experiment, they ran into the lab like a runaway Mustang, such as the flood, block also stopped. This is also the most troubling place for me, every time the only experimental class, the voice of the students will submerge the teacher forever
