Trends analysis on research articles in the korean journal of medical education.

The purpose of this study was to examine the chronological changes and progress in medical education research in Korea and to identify the less investigated topics that need further study and improvement with regard to methodological quality. Of the 590 articles that were published from 1989 to 2010 in the Korean Journal of Medical Education, 386 original research papers were extracted for the analysis. The extracted papers were systematically reviewed using 2 analysis schemes that we developed: one scheme was designed to classify research topics, and the other determined the methodology that was used. The main results were as follows: The most popular research areas were curriculum, educational method, and evaluation in basic medical education; in contrast, studies that addressed postgraduate education, continuous professional development, and educational administration were less frequent; The most frequently studied topics were clinical performance/skills evaluation, clerkship, curriculum development, and problem-based learning, Quantitative studies predominated over qualitative studies and mixed methods (265 vs. 95 vs. 26). Two hundred forty papers were descriptive, cross-sectional studies, and 17 were experimental studies. Most qualitative studies were non-participation observational studies. In conclusion, there has been dramatic growth in the extent of medical education research in Korea in the past two decades. However, more studies that investigate the graduate medical education and the continuous professional development should be performed. Moreover, robust experimental designs and methods should be applied to provide stronger evidence that can practice best-evidence medical education.
