Great job! Overall I think this was good and thoughtful. But!....
I think you can provide examples from the outside world or your own experiences and incorporate them into your essay. Besides examples, I also think you should write a bit more for your introduction, have some background info. Your thesis was pretty good though.
Other errors:
If a student makes comments due to unsatisfactory explanation of a formula, it is called criticism.
Replace comma with semi colon.
I believe a qualified educational professional ought to know
Change professional to professor.
review against him/her as students
Try to best not use slashes, it just looks more professional if you don't.
I hope this helped.
By the way, what kind of essay is this?
