Comparison of Traditional and Web-Based Medical Student Teaching by Radiology Residents

Purpose: Web-based learning tools are increasingly available for use and have been described in the pedagogical literature. However, rigorous comparisons between traditional learning methods and newer collaborative online tools have not been performed. Herein, we describe a web-based curriculum hosted on the collaborative Radiopaedia.org website. This curriculum was compared with traditional learning tools in a randomized, controlled fashion.

Materials And Methods: Medical students rotating through inpatient pediatrics were offered a 1-hour case-based learning session led by radiology residents. Students were randomized to receive online (Radiopaedia.org) versus traditional supplemental educational materials (reading material covering the same content) for review before the in-class session. A 15-point questionnaire was administered at two different points during the rotation: at the beginning of the clinical rotation and at the end of the classroom session.

Results: Fifty-eight students were approached for enrollment and a total of 47 (81%) consented to participation and completed the study requirements. Students who completed the web-based module had higher mean knowledge scores (74%) compared with those who were provided the traditional learning material (68%) (P = .06). Specifically, they demonstrated increased knowledge of the ACR Appropriateness Criteria and the "silhouette sign."

Conclusions: A randomized, controlled, nonblinded evaluation of a novel radiology curriculum intervention hosted on Radiopaedia.org demonstrates improved test scores compared with traditional teaching methods.
