Differential Use and Effectiveness of Practice testing: Who Benefits and Who Engages?

Practice testing is an effective learning strategy, yet low-achieving students often underutilize it despite its benefits. This study investigates who benefits from and who engages in practice testing within an authentic educational setting. We collected data from 325 undergraduates (56% self-identified as female) in a gateway mathematics course, combining survey responses, practice testing records, and exam performance (points, grades, passing). Employing regressions and prediction rule ensembles, we analyzed a comprehensive set of predictors (prior/current achievement, motivational beliefs, personality, and volitional factors). Increased practice testing was linked to improved exam performance, especially for students with moderate-to-high current achievement. Students with lower prior achievement were less likely to test themselves and required more practice testing attempts to achieve similar exam performance improvements. Predictors of practice testing included prior achievement, intrinsic value, and mastery goals. Therefore, integrating low-stakes testing with motivation-supportive interventions may reduce performance gaps and promote equity in higher education.
