The claim pretends to be very intresting, because it can be discussed in hundreds of ways and finally we´ll be always able to find some "pros and cons". Actually, I guess the emphasis should be "What is the problem provided the teacher takes into account the suggestions of the students?" - Of course, there is none. Every teacher does well by being interested in knowing what his students like, of course, it does not mean that the teacher must suddenly change the whole plan and didactic programme. Having an idea of what encourages his students will always give the teacher an opportunity to include those things gradually in what the students like less but still need to know it at any rate. It is a kind of trick but I believe that by means of such trick you succede in getting the students motivated since for the sake of doing what they like more they will be ready to do what they like less. Next emphasis to be made is the question "What do you about the teacher who ignores the opinions of his students?" - I guess, the very question gives the answer... Many interesting things may be added https://domypapers.com to this modern and multilateral subject and all of them match and make sense.
