Dawn, You have a number of factors integrated into your quiz strategy that encourages students to participate and study the required material. I like the way you have developed it because you are asking for effort in the area of content (previous day's lecture and reading assignment) and being on time. If they are late they will miss the points that can be earned from the quizzes so this is working on their soft skill development. I would continue to use this system while getting feedback from your students to see where you can make improvements in the process if they are needed. Gary Gary Meers, Ed.D.
