作为教师经常会有这样的感受,在课堂上总有一部分学生处于心不在焉、神情游离的状态,如果仔细观察,你会发现,一个班级里很少有人能真正做到45分钟都在全神贯注地听讲。所以,很多知识你一再强调,依然有学生无动于衷,很多题目做了又做,讲了又讲,还是有那么人多反复出错。因为,学生在课堂上注意力没有集中。 As a teacher, there is often such a feeling. There are always some students in the class who are absent-minded and look free. If you look closely, you will find that few people in a class can really concentrate on listening for 45 minutes. Therefore, a lot of knowledge you have repeatedly stressed that there are still students unmoved, many problems have done, talk about again, or there are so many repeated mistakes. Because, students in the classroom did not focus attention.
