Changes in academic performance in the online, integrated system-based curriculum implemented due to the COVID-19 pandemic in a medical school in Korea

Abstract

Purpose: This study aims to examine how students' academic performance changed, based on the test results of 16 integrated courses conducted in 3 semesters at Hanyang University College of Medicine that underwent a transition to online learning after COVID-19 in Korea. Methods: For the 16 required courses that included an integrated system-based curriculum that runs for t3 semesters, the major examination's raw scores were collected for each student. Percent-correct scores were used in the subsequent analysis. We used a t-test to compare grades between 2019 and 2020, and Cohen's D was calculated as a measure of effect size. The correlation of scores between courses was calculated using Pearson’s correlation coefficient.Results: There was a significant decrease in scores in 2020 for 10 courses (62.5%). While most of the integrated system-based curriculum test scores showed strong correlation, with a coefficient of 0.6 or higher in both 2019 and 2020, the correlation coefficient was generally higher in 2020. When students were divided into low, middle, and high achiever groups, low achievers consistently showed declining test scores in all three semesters. Conclusion: Our findings suggest that the transition to online classes due to COVID-19 has led to an overall decline in academic performance. This overall decline, which may occur when the curriculum is centered on recorded lectures, needs to be addressed. Further, medical schools need to consider establishing a support system for the academic development of low achievers.
