Being a teacher

Yesterday, I took part in one workshop, concerning how to evaluate the classes we've been giving. The moment I was there, I knew that I got wrong about this concept. I understood it as "how to get feedbacks from the students so that the class can be improved in the future," but apparently the workshop was more about "how to exam the students so we could know whether what we've tried to teach have been learned or not." Anyway, some brilliant ideas has still sparkled me. For instance (cited from one college but not the original words), "the teachers, to me, seem always very helpless and alone. You are the one standing in front of 20 or more people, but they belong all to one side -- students. We are the only one and we need to confront all the stuff, conflicts, problems, and whatsoever ourselves."
On the other hand, some one pointed out that "we are not teaching but enlightening." This thought really interested me, as it is so related to the "Cognitive Theory." People can never learn anything unless they learn it all by themselves, or in another word, experience the whole process. Only when they experience it, they might understand and then learn it. Without this process, even though they may pass the exam, the knowledge will still be gone and would never help in their later life. And that's why some of the colleges said, "Personally, it is always significant and exciting that I could solve some problems or conflicts myself with what I learned from the class."
Another interesting thought was that sometimes the students do feel bored about what are taught in the class. Then one "desperate" teacher (no offence) shared with us her own experiences that the students complained about her materials. What she believed sometimes bothers me as well. "The students are adults, they are grown-ups. They are not children any more. They can no longer just stop doing something merely because of its boringness. They come to the university to learn, to study." To get something, some thoughts, better some smart ideas should be their tasks, but not only the interesting stuff!(my additional words) And then, the problem comes, everyone has a good reason to go to the university, choosing his or her major, for a good job, for interests, for future, whatever. How can we, the teachers keep their good reasons going on and at the same time teach them something that we consider important?
A big thought in big: EDUCATION IS A HUGE PROBLEM EVERYWHERE IN THIS WORLD, the degree of development of one country or area can not help.
