How do "good" college teachers present information?

According to Meiland, a " good" college teacher presents information in the following way. Good college teacher spend much time talking about the basis on which this information is current believed. The reason why Meiland thinks it is important to understand the material. Moreover, college students were required a different and higher type of understanding, critical examination and evaluation.

I almost agree with Meiland's opinion but I don't agree with his opinion on this point. He says college students need to acquire high type of understanding, however I don't think so. that's why high type of understanding sometimes prevent from thinking of a nice idea. And we can not imagine what happenes in our life, so there is no necessity for cultivating high type of understanding. if you want to know about it , you can easily get usuful information by Internet, book and so on.
