Natural Blogarithms

It took three classes but I finally finished all of the section over Matrix Algebra. During today’s lecture we walked through the concepts of matrix inverse and then matrix transposes. Its amazing how long these lectures stretch out when you choose to demonstrate the concepts with examples involving matrix operations. As far as I can tell, they are all following along very closely, except when I start going off on a tangent and trying to draw connections between linear algebra and higher level mathematics. [..]

During Calculus IV on Tuesday, we had Exam I. I’ve decided that I’m not generally very good at producing tests at the appropriate level for the course. Usually they are much too hard (1 or 2 problems that require a LOT of tedious calculation) or too long (too many problems). The reason is not that I am particularly mean-spirited but that the my writing process is flawed. [..]

During I.A. on Tuesday (Holy Cow 7:25 am is early to start a class) two students present problems at the board. I really enjoy having this part of the class. All of the students have had a colleague of mine for class and that has been a regular part of her upper level courses that she teaches. They are all used to it, but it is new to me. I enjoy hearing the though processes of the students. I even developed Rubric to grade these presentations. Don’t I sound like an education major? (By the way, I was never formally trained to teach.)
