Mind Mapping to Enhance Critical Thinking Skills in Physician Assistant Education: A Randomized Controlled Study

Physician assistant (PA) students need to assimilate and integrate voluminous information quickly and effectively to promote critical thinking skills required to deliver competent care. Mind mapping (MM) is an innovative strategy used to facilitate students' recognition and recall of essential information and to ensure depth in their understanding via making connections between pieces of information. The establishment of relationships between concepts expressed in mind maps enhances critical thinking skills. The purpose of this study was to determine the overall critical thinking skills of PA students using MM as a learning strategy and to determine if there was a significant difference in critical thinking skills between students who used MM versus standard note-taking in their learning environment. In this randomized control study, a convenience sample of 74 PA students was assigned to a standard note-taking group (SNTG) or mind-mapping group (MMG). After completing the Health Science Reasoning Test (pre-HSRT), MMG members were instructed on how to construct mind maps and then asked to create weekly mind maps for 9 weeks, while the SNTG followed their method of study without mind maps for 9 weeks. Differences in the mean pre- and post-overall HSRT scores between groups and within groups were analyzed using independent and dependent t-tests, respectively. There was no significant difference between pre- and post-overall critical thinking scores as measured by HSRT after 9 weeks of intervention in both groups. However, there was a significant difference in the mean overall post-HSRT scores between groups (p=0.026). Hence, mind mapping is a viable active learning strategy to promote critical thinking in PA students.
