The body of evidence supporting the effectiveness of regular quizzes on assigned readings continues to grow. They’ve been shown to raise exam scores in courses from different disciplines, at two- and four-year institutions and with varying quiz logistics (online and in class, for example). It’s important to note that the impact on exam scores is not dramatic. The study referenced here cites three earlier studies that made similar use of reading quizzes and all four report exam scores increased 2–5 percent.
