I really find 'Flash Cards' a good way of testing how much I can remember the German vocabulary and grammer . I typically don't do them along with the lesson , but later on, to test how much I remember after a long gap .
I wish you could add more tools for students to test their knowledge other than 'rocket reinforcement' .
Any thoughts ? Some thing like :- 'Create new sentences using existing learn't vocabulary' or 'translate the given new sentences in German'.
