I got some feedback from my students that would make video lectures more engaging. Some students said it was hard just to watch the videos, even with included quizzes. I asked them to give some ideas on how to make the videos more engaging, and one student said it would be great if you could comment on the video timeline, like you can with Soundcloud. That way if a student has a question, someone else watching the video or me as the teacher could add a response to answer their questions. This process get everyone involved and has benefits for both students and teachers. Thoughts?
