The assistant professor, associate professor, and professor are teachers. So, the main aim of being a professor is to be a champion in the field of teaching and, of course, research. To me, this is the main task and the core business of a professor. I will be happy if I can manage to educate students who formerly come with a low academic record to be successful in the academic world. It is a challenge and satisfaction as an educator.
I am sad to see students with a low academic record who have the intention and spirit to continue their study can not be accepted as M.Sc. or Ph.D. students by most of the professors. It is because these professors assume that students can not contribute to their prestige as a professor.
So, what is the purpose of being a professor?
