Evaluation of Student Peer- and Self-Grading in an Integrated Pharmacotherapy Course

To determine if student peer- and self-grades correlate with faculty grades on case vignettes.

This study involved first professional-year students enrolled in an Integrated Pharmacotherapy course. The course included three modified team-based learning (TBL) activities (each consisting of individual and team readiness assurance tests, followed by three open-note case vignettes completed in teams). Each student uploaded completed case vignettes to the learning management system and was assigned to complete a self- and a random, anonymous peer-grade using a provided key. Peer- and self-grades were compared to faculty grades using a null multilevel model to determine the intraclass correlation coefficient (ICC). Faculty time spent grading was captured, and students were surveyed to determine the perceived value of peer- and self-grading.

Faculty- and peer-grades had a slightly higher correlation than faculty- and self-grades (ICC = 0.75 vs 0.73, respectively). The ICC between all three grader groups was 0.74. Faculty spent an average of 2.5 h grading the cases after each TBL session. Students reported spending a median of 36 min on the peer- and self-grades for each TBL session. Overall, students agreed that both the self- and peer-grading activities helped identify gaps in knowledge (90% and 56%, respectively). A total of 78% of students agreed that self-grading was beneficial for their learning.

There was a moderate-to-good correlation between peer-, self-, and faculty- grades for case vignettes. Faculty time may be saved through student self- or peer-grading.
