A person who has a ph.d. is a law requirement to teach colleges.
What about those who did not recieve no ph.d.? and recieve an invitation to teach?
IF you study and got a ph.d. in like law, is he a good lawyer? If he got a buisness phd. is he rich? Is his aim, is to make his students be like him?
Now, those who have mastered life( what we assume life is about)
is he good then? He lived universally succesful does that means a successful life leds to a successful teaching( right method of teaching ).
What about this, if you have a ph.d. does that means he is really good at something what he talks about, or just good at what he remembers and knows about?
if i understand you correctly, this is what you mean.
In order to have a good teacher, you must have good students. In order to have good students you must have a good teacher.
A good student is a person who is willing to participate, listen, respect, and bring out entusaism for the other classmates to arouse questions.
While, a good teacher, is to answer questions, teach their objectives, and bring a friendly and discpline atmosphere in the class.
