Accessing student interests in ICS3C/3U

I’m thinking about trying to tap into the students’ interests in my online computer science course. We’re at the point now where the [up-to-date] students have enough of the basics to be able to pursue topics of their choosing.

I was considering making a discussion forum/topic where they can share ideas they’re interested in, and then encouraging them to pursue that learning. I’m not sure how to word it, or manage it, or what exactly I hope to get from it, except that it’s important for students to take┬ácharge of their own learning. Maybe several students will have similar interests and be able to pursue them together.

Suggestions are welcome ;)
