Thanks Paula for the great ideas. I make use of this feature in quizzes. According to my "schema", I use quizzes for assessment and review (then I use the fantastic features of the quiz module), and the lessons and the book for presenting new content (I think in a similar way like Nico).
But next time I wil definitively try to present new information with a quiz. Some teachers have recommend this so it must work.
Regards,
Beatriz.
