For my first course on CS topic (first course on the topic and not the first overall), I used the university evaluation system to ask students about their feedback.
In addition to responding to questions by giving rates, the students were also asked to specify what they liked and what they didn't like. There are some comments that are obviously wrong but among which, there are comments that the students believe are true.
One common comment is that the slides contain many formulas and they claimed that most of them are not necessary because they didn't understand the lectures. In contrast, they could understand the topic from youtube videos without all these formulas.
I wanted to teach the topic from the right perspective of master university level. but it seems that the students prefer animated lectures, which are useful to understand the overall idea but not the core of the topic, especially because math/algebra is important in this course.
I am wondering whether I should satisfy the students' opinion or I should keep the current way which I find more useful to reach deep understanding.
