Pre-class preparation is a crucial component of team-based learning (TBL). Lack of preparation hinders both individual learning and team performance during TBL. The purpose of the present study was to explore how the grading of the individual readiness assurance test (iRAT) can affect pre-class preparation, iRAT performance and performance in the end-of-year examination. Using a quasi-experimental design, Year 1 and 2 students' download frequency for their pre-class materials, performance on iRAT and examination were examined under two conditions; (1) under which the iRAT was graded and (2) under which the iRAT was ungraded. Medical students (N = 220) from three cohorts were included in the study. Differences between both conditions were tested by means of six separate ANCOVAs, using medical school entry test scores as the covariate to account for potential cohort effects. Results revealed that students were downloading more pre-class materials prior to their TBL sessions, and were performed significantly better on iRAT when their performance was graded, even after controlling for cohort effects. Analysis of covariance demonstrated that performance on iRAT also appeared to affect performance on their examination scores. The results of the study suggest that grading has a positive effect on students' iRAT scores. Implications for TBL are discussed.
课前准备是团队学习（TBL）的一个关键组成部分。缺乏准备会阻碍 TBL 期间的个人学习和团队表现。本研究的目的是探讨个体准备保证测试（iRAT）的评分如何影响课前准备、iRAT 表现和年终考试成绩。本研究采用准实验设计，在两种情况下（1）iRAT 评分和（2）iRAT 不评分，检查了一年级和二年级学生下载课前材料的频率、iRAT 表现和考试表现。研究纳入了来自三个队列的 220 名医学生。使用入学考试成绩作为协变量来控制潜在的队列效应，通过六个单独的协方差分析检验了两种情况之间的差异。结果表明，学生在 TBL 课程之前下载了更多的课前材料，并且当他们的成绩被评分时，他们在 iRAT 上的表现明显更好，即使考虑了队列效应。协方差分析表明，iRAT 的表现似乎也会影响考试成绩。该研究的结果表明，评分对学生的 iRAT 成绩有积极影响。讨论了 TBL 的影响。
