The question of expectations is an important one. But there are very real limits as to what one can expect.
Simple quizzes are just that - a simple test of minimal involvement with a class.
All this I make quite clear. What I find, as I go through the semester is that this can work. But, with the studen ts who stick it out, I find that the quizzes can get harder, and more related to text content, as the semester progresses. Moreover, many students improve.
