my view on examiations作文

In most schools,exams is used as a chief means of deciding whether a student succeeds or fails in mastering a particular subject.Although it does the job quite efficiently,its side effects are also enormous.
To begin with,exams lower the standards of teaching.Since teachers are often judged by exam results,they are reduced to training their students in exam techniques.No subjects can be taught successfully merely through being approached with intent to take exams.In addition,the most undesirable effect is that exams encourage bad study habits.As the exam score is the only criterion for his academic performance,a student is driven to memorize mechanically rather than to think creatively.
In fact,few of us admit that exams can contribute anything really important to the students’ academic development.If that is the case,why cannot we make a change and devise something more efficient and reliable than exams?
In my opinion,exams is necessary,but schools should reduce times and difficulties for exams.Besides,teachers are not supposed to look down the students who fail in exams.
