“Do we really need to have all of these quizzes?”
When it comes to designing e-learning programs, it’s not unusual for clients to question the need for the number of integrated quizzes, exercises and self-checks. There’s a knee-jerk reaction that most of us experience when we hear that we may be quizzed on a topic and yet, research supports that quizzes and tests are more than just useful tools for assessing what people know.
Research on “retrieval practice”—bringing information to mind through questions, self-checks, or quizzes—shows that it can improve long-term retention compared with simply reviewing material. In some studies, retrieval practice has outperformed approaches such as additional studying or concept mapping.(1) Importantly, the benefit isn't limited to measuring recall: the act of retrieving information can itself strengthen later learning and retention.(2)
In my own eLearning work, the evidence has been more anecdotal. Learner feedback and assessment results have suggested that thoughtfully designed self-checks can support comprehension and recall, although they don't establish a precise improvement attributable to the quizzes alone. We consider question format, difficulty, feedback, and opportunities to try again. Because learners can be wary of tests, it's important to use these activities judiciously—not interrupt learning with a constant barrage of questions.
Most learners probably won't celebrate another quiz. But when the goal is learning that lasts, well-designed retrieval practice deserves a place in the experience. The point isn't to collect more scores; it's to give learners meaningful opportunities to remember, apply, and strengthen what they've learned.
