As a first time instructor on a college level basis I found some results after our first exam that were opposite of what I thought the scores would be. The students who I worried about the most, who were always asking questions, or asking for clarification did the absolute best on all of the tests. When developing the next exam, I asked each student to write 2-3 test questions that they thought were important and should be on our next exam. Because the students had to develop some questions, they read each chapter more in depth and came to class better prepared. They also scored much higher as a whole on the next exam. I think that because they felt some ownership of their education, they worked a little harder when reading and studied even harder for the tests.
