I can understand that would be a difficult task: thank you for putting your mind to it nevertheless.
Now that you've explained how to display the Activities block (I got lost in the upgrade to 2.4), students will be encouraged to view their responses more easily.
I tried embedding the responses and my feedback handout in the same Moodle html page, but the result is a very crowded page which is difficult to read. Side by side is no better.
(See screenshot: the questions appear in reverse order, although there is no shuffling in the HotPot exercise.)
I think a simple html page containing my handout (as the 'next activity' in the Hot pot settings) will do just as well.
Many thanks for your help,
