Evaluating open-note exams: Student perceptions and preparation methods in an undergraduate biology class

Abstract

Although closed-note exams have traditionally been used to evaluate students in undergraduate biology classes, open-note exams are becoming increasingly common, though little is known about how students prepare for these types of exams. We investigated student perceptions of and their preparation habits for online open-note exams in an undergraduate biology class, as compared to their previous experiences with closed-note exams in other classes. Specifically, we explored the following research questions: (1a) How do students perceive open-note exams impact their exam scores, their anxiety, the amount they studied, and the amount their peers studied? (1b) How do these perceptions impact performance outcomes? (2a) How do students prepare for open-note exams? (2b) How do these preparation methods impact performance outcomes? Results demonstrate students perceived increased exam scores, decreased exam-anxiety, decreased study time spent personally, and decreased study time spent by their peers for open-note exams, as compared to past experiences with closed-note exams. Open-ended survey responses analyzed through firstand second-cycle analyses showed students adapted their study habits by focusing on note preparation and broad conceptual understanding rather than rote memorization. Using linear mixed effects models to assess student performance, we found students who focused on understanding, note preparation and using external resources outperformed students who did not report those study habits. As institutions shift towards flexible and scalable assessments that can be used in face-to-face or online environments, the use of open-note exams can promote effective study habits and reward higher-order thinking with intentional guidance from the instructor.
