Throughout the period of session, who is the center of the class, the teacher or the students? explain

No doubt the center is teacher as he is one the guides students. But a good teacher should think that he is not on the focus but the students. 

in my opinion  students are the center of the class because it is all about them and depend on studies done when the students envolved in the course representation the amount of understanding increase

so the more students given more oppurtunities to and chances to participate in classes the more the courses are easy to understand by them
