This study investigated whether the benefits of comparing procedures extend to comparisons that involve informal and formal procedures. We also examined how learner(More)
Given recent findings that test-enhanced learning (TEL) improves students' understanding and retention of material through regular quizzing (e., we incorporated TEL-inspired online quizzing into a cognitive psychology undergraduate lecture course. With the addition of quizzing to the course, class performance improved according to several criteria relative(More)
