In colleges and universities, the phenomenon of students’ skipping classes is not unusual. There are often some students who skip those classes for feeling unwell or other private reasons. Besides, still some students don’t go to class without any reason but for they don’t want to.
There are two main reasons for college students skip classes.First,compared with middle school ,students have more ** in college.It depends more on one student's consciousness whether he will attend the class.So those students lacking self-discipline begin to skip classes.Second,some teachers' classes couldn't attract students' interests so that some students who rather skip classes to study what they are interested in.
For whatever reasons,skipping classes does bring negative affects on students' study.Therefore,it is necessary to take some effective measures to reduce those phenomenon.On the one hand,the school and teachers should make students realize the negative effects of skipping classes and increase their consciousness of attending the class.On the other hand,teachers have to improve their teaching quality to attract students' interests.Only in this way can the phenomenon of skipping classes be reduced as soon as possibly.
