The activity has now closed and students need to be able to see how people evaluated their work.
When the worskshop is closed, students are supposed to see their own submission (and eventually other's submission they were assigned to assess). The title of their submission (e.g. "6 a day" in the attached screenshot) is a link that opens the full submission text together with all received assessments.
I agree this may not be obvious. I'll appreciate if you report it as an usability bug in the tracker. At least the list or number of received assessments should be displayed at that page.
