It is really amazing that we can not explain quite easily things that we know, or at least we think that we know well. I see students that even if they have been taught a simple method, let’s say last year or last semester, they are unable to recall it one semester after. I do not think this is a student’s problem actually. The student read the material, completed the assignments, took the exams. But still there is a gap of knowledge… Why? where does this come from and why it is always the same, since I was an undergraduate student, 4 years ago. I remember that this is the “global” idea many students have into their minds for teaching, many years now. Why is it so hard?
I had the chance to be a teaching assistant this semester, so I am trying to understand.. guess what.. I can not find it and amazingly I do the same mistakes that my teachers did. What did I learn then? how to teach following the same mistakes as 20 years ago? Is it something psychological that we do not know yet ? .. students are leaving the class without understanding, it sounds frightening..
