I found some validation in my practices within this portion of the security topic. In my class students have quizzes every time class meets with the lowest two quizzes dropped. I review the material beforehand by going over the previous lesson's homework with the class, I allow time for additional questions, and then we take the quiz. I originally began this practice to "force" to work with the concepts taught in small doses as opposed to "cramming" before the exam, but I do believe it increases their security with their grasp of the material as well. I let my students know that the material on these quizzes is the same that will be on either their midterm or final exams and that this is in some ways their practice run at it. When I return quizzes the following class we go over the questions as a class which allows them to evaluate what they understood and what they did not and in my belief gives them a better idea of what they need help with or to focus on when preparing for exams.
