In my opinion, this measure is generally advisable, but not necessarily Firstly, students are the best candidates to evaluate their teachers They are the direct objects of the teachers' work No one is more clear about if the teachers are capable than the students in the course For example, other faculty may be able to tell if his colleague is good in his research work, but he knows little about if others teach well On the contrary, the students take lectures, so they know if the professor is a good teacher The evaluations from students are more precise than that from anyone else So schools should ask students to evaluate their teachers Secondly, the teachers have responsibility to their students If a teacher is incapable, his poor teaching will obviously affect the students who take the course So students should have the right to evaluate their teachers In case that the teacher was incapable, the students should take some measurements to improve the teacher's performance, or to change another teacher To evaluate their teachers is the best way to so Thirdly, this kind of measurements can invoke the potential of the teachers Were there no evaluation, some teacher might think there is no difference weather he teaches well or not, and then will hesitate to work hard to improve his teaching This is disadvantageous both to the teacher and to the students While, if the teacher is aware that his work is to be evaluated by his students, and then he will be push to prepare his lectures better However, this is not to say that evaluations from the students are always helpful In some case, the result of this kind of evaluation is misleading I happen to know a teacher in the physics department, who is giving lectures to some students in engineering major Unfortunately, it seems that the students not like physics course a little Although the teacher prepares his lectures very well, the students feel it boring So they give a poor evaluation to the teacher This story tells us that evaluation from students might be misleading In sum, asking students to evaluate their teachers is generally helpful But the results from this evaluation should be studied carefully, in case that they are misleading
