The Effect of Graphic Organizers on Learning Outcomes, Study Efficiency, and Student Satisfaction in an Elective Veterinary Cardiology Course.

Abstract

Graphic organizers (GOs) are visual and spatial displays, such as tables or charts, which facilitate learning by making conceptual relationships between content more apparent. We hypothesized that study aids in the form of GOs would lead to improved learning outcomes, study efficiency, and student satisfaction compared to traditional outline (OUT) format. A mixed-methods prospective randomized crossover trial was undertaken with veterinary students (n = 31) in an elective cardiology course. All students received identical content presented via weekly in-class lectures. Following 8 pre-designated lectures, students were given instructor-prepared study aids in either GO or OUT format. Students completed quizzes of content knowledge for each lesson and indicated amount of time spent studying. Crossover occurred such that groups of students alternated between receiving GO and OUT. Quantitative and qualitative data were collected in the form of in-depth pre- and post-course surveys. Quiz scores did not differ (p = .42) based on type of study aid provided (GO vs. OUT). Students spent an average of 17% less time studying per lesson when using GO compared to OUT (p = .05). Student satisfaction with both study aid formats was high, but students preferred GO over OUT in terms of study efficiency (p = .002), visual appeal (p < .001), ease of use (p < .004), and likelihood of referencing in the future (p < .001). In an elective veterinary cardiology course, use of GO compared to OUT format study aids resulted in higher study efficiency and student satisfaction with equivalent short-term learning outcomes.
