Reflexion

 I disagree with the teacher that sais " It is difficult to use different correction techiques with different students",maybe it is, if you are not interested in your students, which is the case of a lot of teachers I have met during my life as a student. But I think that is not too difficult to get a picture of the students even in the first class. Once, i had to prepare a class for the group, and I inmediately notice what were the principal student's characteristics, maybe at the beggining you are going to pay more attention to the truoble makers and the most participative ones, but then, you will have the opportunitie to met the rest of the class in just a few classes more.This is very important if you want a succesful learning. For example if a student is shy and maybe he didn't talk too much in classes, is going to feel embarrased in front of the others if you correct him in a very notorious way. So, I think that part of the teacher's role is to pay attention to the student's need to improve their English learning experience.
