Trying to get students to re-do only certain topics.
My students have been on Duolingo before, so when I assign a topic for them to complete, its comes back completed prior to the date that I had it assigned. I would like to give them drills and repetition, and this makes it a bit more difficult. Any tips?
The Duolingo for Schools system doesn't let you do that. You could set strengthening that skill as a homework (not using the D for S system), and get them to hand in a screenshot of the completed strengthening.
