I have set up a standard discussion forum for facilitators and students to post and responds to medical cases. Facilitators post numbered cases and each case is a new post. Students also post their own cases as a separate forum post. Students are required to contribute to at least 15 cases and post one case of their own. We now have over 50 cases in the system. I set up the standard forum because I wanted to have a one-stop shop, rather than 50+ individual forums.
My problem is that the forum is getting really messy and challenging to use for both facilitators and students because the cases/discussions are no longer in numerical order. So finding which cases are still active is quite challenging. Also, I don't know how to close a discussion. Even though an answer has been posted to many of the earlier cases, participants who need to complete the requirements are posting in these.
We have only one week to go before the forum is closed but I would really appreciate any suggestions for how I should go about setting this up for next time.
