Lack of Peer Learning in Discourse

One of the motivations for setting up this platform was to promote peer learning when all teaching is online and interaction is lacking.
I expect students to participate in answering questions - especially questions about tools and questions from previous exams. The whole point is that students have experienced these issues, understand these questions immediately, and know the answers.
Somehow, this has not happened, and it has become the “job” of Aakash and myself to follow the questions. This was not our original intention at all. I have to admit that I’m disappointed!
