should teacher be evaluated and criticized by students?give your opinion in English,thank you

I think teachers should be evaluated and criticized by students for the following reasons:
Firstly, teachers are no longer authorities as they used to be in ancient times;
Secondly, evaluation and criticism by students will help the teachers to become better in teaching;
Thirdly, students are also the subjects of educational evaluation;
Finally,teachers also hope that students can give them proper evaluation and criticism, so as they can improve themselves.
