I like this. Related, this semester I've been using handwritten quizzes in class. A simple change that's been one of the best things as it changed students' expectations of class prep. Kind of do the readings and sort of prep and you can coast in class. But if you need to write out quiz answers you're forced to know the material better as well as maintain the ability to express yourself.
I also use low-point bonus questions to test general knowledge (huge variation on subjects I thought everyone knew).
