This observation is of my TA supervisor at the course for which I later gave the guest lecture. I came to one of the lectures before my guest lecture to get a better feel for the dynamics of the class and the format of the instructor’s lectures. I have also used it as an observation opportunity.
This instructor has her own teaching style, which I overall enjoy, but in this lecture one thing that really struck me was the lack of any text on the slides, with the majority of them only containing visuals, pictures, drawings, maps, etc. There were no key points or summary highlights. That is one thing I was interested in discussing with the instructor in our post-observation meeting to check in with her about how much of her slide design was intentional.
