I would like to know if there is a way to unpublish (I know this cannot be done), lock, hide assignment entries (specially text entries) from students after they have already submitted them at my leisure.
When I am doing exams with prompts that are similar to the practice prompts I don't want the students to copy or look at their practice entries. I teach a world language and I want them to write honestly but have a hard time with their practice assignments within reach. My school has dyknow, which allows me to block them from other websites but not from within Canvas. In this occasion the enemy is within.
