An individual reflection paper (IRP) is a structured method requiring a student’s written reflections on knowledge acquired and aspects of it to discuss at the student’s next tutorial meeting. Previous experience and research on problem-based learning (PBL) have shown that the use of IRPs can act as a support for students’ preparation for and learning in tutorial groups. It also appears that an IRP can facilitate tutors’ assessments and examinations of students’ individual engagement and contribution in tutorial groups. Against this backdrop, we aimed to explore if an IRP can act as a means to support group exams in PBL. Even though using group examinations aligns well with the epistemology of PBL, the dilemma of using joint learning while at the same time fulfilling individual assessment requirements is thought to make group exams become difficult to use. 152 IRPs were used as a basis to assess whether a particular group of students had acquired knowledge that would impact results on a group examination. By evaluating each student’s submitted IRP, examiners were able to determine the extent to which each of the group participants contributed newly acquired knowledge to the content of the examination. Overall, completed IRPs clearly showed concurrence between acquired and requested knowledge, except on a few occasions. The findings are promising and suggest that IRPs can act as a means to support group exams in PBL.
