Differences in medical student performance on examinations: exploring score variance between Kolb's Learning Style Inventory classifications

Kolb's Cycle of Learning Theory acts as a foundational framework for the evolution of knowledge gained by learners throughout their education. Through Kolb's cycle of experiential learning, one's preferred way of learning could impact academic achievement in the pre-clinical years of medical education.

The medical student classes of 2020 and 2021 at a public university in the southeastern U.S. were invited to complete Kolb's Learning Style Inventory (LSI). For those participants completing the LSI, examination results for their pre-clinical blocks were obtained and matched to the LSI results. Examination scores (locally-developed examinations and customized National Board of Medical Examiners (NBME) final examinations) were compared by LSI classification for each examination using Kruskal-Wallis Test.

Out of 360 possible participants, 314 (87.2%) completed the Learning Style Inventory. Convergers and Assimilators made up 84.1% [Convergers (n = 177, 56.4%), Assimilators (n = 87, 27.7%)]. Accommodators (n = 25, 7.9%) and Divergers (n = 25, 7.9%) made up the remaining sample. Accomodators' scores were significantly lower on locally-developed examinations in Principles of Medicine, Hematology, and Gastrointestinal System. The only NBME examination that demonstrated a significant difference across learning styles was from the Cardiovascular block.

Upon reviewing Kolb's LSI, our study indicated that performance on the customized NBME examinations minimized the variance in performance compared to locally-developed examinations. The lack of variance across learning styles for all but one NBME final examination appears to provide a more equitable assessment strategy.
