How do good college teachers present information?

According to Meiland, a good college teacher presents information in the following the way.
By discussing, examining and talking about the basis of current beliefs, teacher presents them.Good teacher focuses on understanding the material. So, teacher take materials as beliefs or conclusions reached through investigation, and students can get the information.
I agree with Miland's opinion because I feel that good teacher focus on discussing, investigating, examining and so on in the class. I think these things are needed to approach the material of the problem. And good college teacher's way encourages to extend the my possibility.
