Should students evaluate their teachers?

Some people tend to think that schools should ask students to evaluate their teachers while others fear that it will bring about some harmful effects to both teachers and students. In my point of view, I believe that the evaluation has more advantages than disadvantages. The argument for my claim goes as follows.  

First of all, asking students to evaluate their teachers can conceal some inappropriate aspects in the course of the process of teaching and learning, in order to make the teaching more reasonable and effective. This process is interactive and it constitutes more than one part. Sometimes, teachers do not realize some occasional mistakes they made when they have classes and sometimes the way that they train the students is not quite suitable for the students. As a result, the quality of their education is hard to reach the satisfying level. Taking measures will make teachers realize all these facts, thus improving their education by means of making some adjustments.  

Second, since education is a ˜wo-part?process, the evaluation will probably play an important role in stimulating the creativity and activity of the students, when schools ask student to evaluate their teachers. They may feel that they are treated equally, not submissively. The sense of equality will make them participate the teaching more actively.  

However, there are also some disadvantages in it. For example, some teachers may consider himself authority, never to be suspected. This enactment will make them feel uncomfortable and have the prejudice to these students who evaluate them.  

After all, though these disadvantages really exist, the advantages outweigh. So I strongly recommend that the measures should be taken as far as possible.
