I'm currently working in the development of a course for Electrical Engineering at the UNSW.
Currently, there is a Course Feed tab installed in the course (see attached image) that can serve as a dashboard for all the post from the different learning activities. However, several students upload images without sense just to complete with the participation mark; hence, the genuine questions are hard to find and sometimes they get lost.
So, a possible solution would be to have a sub-tab called "Exam Queries" (for example) under Course Feed that only shows the posts from the learning activities that have been tag using "Exam Queries" as a tag. This can be replicated for many other tags. So, in the end, you will see all the tags for Course Feed as sub-tags.
What do you think?
