The professors found that the students in the classes subject to quizzing did better not just in the introductory psychology course, but in other courses that semester and in courses in subsequent semesters. There was also a significant reduction in the difference in performance between students of higher and lower socioeconomic standing, something that had been notable in prior sections of the course.
The professors noted that the improvements they observed "most plausibly reflect changes in students’ self-regulated learning – their ability to study and learn more effectively." They also noted that attendance was high in the classes where quizzes were given, which would also influence student performance. It stands to reason that when students attend class regularly and do the course reading, that they will learn more and that their performance on tests will be improved. No one likes testing, but it can help keep students -- at least college students -- on track for success.
