Ready or Not: A Crossover Study of (Un)graded Individual Readiness Assurance Tests in Team-Based Learning.

Objective: This study aimed to measure the effects of graded vs ungraded individual readiness assurance tests (iRATs) on the students' test scores and achievement goals in a team-based learning classroom.

Methods: A 2 × 2 crossover study was conducted in a required second-year pharmacotherapy course. Teams 1 to 8 were assigned to a UG iRAT during the first half of the course, followed by a G iRAT the second half of the course (G/UG group). Teams 9 to 16 were assigned to the opposite grading sequence (ie, UG/G). A multivariate analysis of variance was used to analyze the differences in test scores, as measured using iRAT and examination scores. A separate multivariate analysis of variance was used to examine the differences in achievement goals.

Results: There was a significant difference in test scores based on the iRAT grading condition. Individual readiness assurance tests were higher in the G condition (72.51% vs 67.99%); however, the examination scores were similar in the G and UG conditions (81.07% vs 80.32%). There was no statistically significant difference in the achievement goals based on the iRAT grading condition.

Conclusion: In a required second-year pharmacotherapy course that uses team-based learning, student performance on the iRAT was modestly lower in the UG iRAT condition; however, the students' examination scores were unchanged. Achievement goals were unchanged based on the iRAT grading condition.
