There are different type of teachers .
I have divided them into 3 categories according to their ways of teaching.
I call the first group leaders. They are perhaps the most welcome teachers. They lead to their students along the way of knowledge.
In class ,they only analyze the most difficult and important part of the textbook and leave the details to the students to learn by themselves . They give the students free time to discuss problems instead of showing them everything. They do not give an excessive amount of homework but enough for student s to grasp what they have learnt.

The second group are followers beacause they do not seem to have brains of theirs own and they follow exactly what the textbook says.During the calss,they just transfer evrything from the books to the blackboard , no more ,no less. You can easily find this type of teacher beacause there are always several sleepers in their
class. They give a lot of assignments . Students usually do not like them and think they are evry oppressive.

The teachers who fall into the third
catrgory are free talkers . They are usually knowledgeable and are fond of showing their new ideas to their students .They talks
about the things that they want to say but not what the textbookwants to them to say. They know how to attract students , broaden
their minds and make them think more proundly. Since exams exist, this way of teachingmight not be widely accepted beacause students will not get high marks .
I think if possible , every student prefers this way of teaching beacause he/she can obatain knowledge in a pleasant way.

Perhaps there is till another category , but i think most college teachers fal into these three categories.
