So I was curious--how long do each of you take to prepare for lecture? I tend to organize my thoughts and what I want to say through the creation of Powerpoints, but it takes me a ridiculously long amount of time to do this--like, 4-5 hours per 20-30 min lecture. Which, given that I'm teaching 3 times a week, takes up most of my time. I can prep Powerpoints themselves quickly, but it just takes me forever to think out the "bulletpoints" I want to cover.
Are any of you having a similar experience, or have advice on how to prep more efficiently?
