I will soon be teaching my first class as an assistant professor. The class is made up of 130 undergraduate students, most of whom are in their first year. The class in a introductory course, so I will be giving an overview of the field; for each lecture I will going through one different topic, with most of the material being qualitative rather than quantitative.
Last year the class was taught by Colleague A, so I am adapting his material to prepare to teach the class. Colleague A's lecture slides tend to be too sparse, i.e. there are few words on each slide, and it is not easy to follow the train of thought by reading the slides. Another colleague, Colleague B told me that students had mentioned to Colleague B that students were unhappy with the lack of details on Colleague A's slides.
I feel a little stuck because when I prepare slides for an academic presentation, I try to keep my slides more sparse so as to not overload my audience who may be trying to read my slides and listen to me simultaneously. As I prepare the slides now, I feel that I may be erring on the side of putting too many words in my slides, e.g. the entire slide is covered with words.
How do I find the right balance of how much information to put in my lecture slides to keep students happy?
