A new study by Butler Center Director Fady Mansour , Stefani Milovanska-Farrington of Florida Polytechnic University, Nour Kattih of Middle Tennessee State University and Mohammed Saeed of King Abdulaziz University investigates whether the mandatory submission of answers to practice questions improves students’ performance on the practice quizzes and subsequent economics exams. As the study explains, it is well-known that practice helps students learn because taking a quiz or exam requires recalling information – a phenomenon referred to the academic l iterature as the “testing effect.” To explore this effect, Mansour and his co-authors collected data from five sections (three face-to-face and two online) of an introductory macroeconomics course at a four-year public university located in the southern United States.
