Evaluation of the Pedagogical Impact of "Traum'Cast" Podcast: A Pilot Study Based on Metacognition.

ABSTRACT

INTRODUCTION: With the evolution of educational tools, the French Military medical service has created a podcast program, Traum'Cast, about the principles of war medicine, accessible online for free. METHOD: Our objective was to measure the learning effect of the Traum'Cast program's first episode. A non-randomized pilot trial between July and December 2021 included 80 health care providers 40 in the video podcast group compared to 40 in a group reading a pdf file providing the same information. Using a 10 MCQs, we evaluated knowledge acquisition before, just after, and 2 weeks after the intervention. It was measured using metacognition tools based on confidence marking (number of correct answers, score weighted by certainty level, and realism). RESULTS: Knowledge acquisition was better in the podcast group than in the pdf file group immediately after the intervention (correct answers 9.0 [9.0-10.0] vs 9.0 [7.8-9.0], P = 0.015; weighted score 177.0 [159.0-198.0] vs 160.0 [129.5-176.5], P = 0.020). This difference was persistent 2 weeks after (weighted score 127.5 [101.8-145.2] vs 105.5 [74.2-128.5], P = 0.023). CONCLUSION: This podcast is an innovative teaching tool which has proven to strengthen the knowledge of the principles of war medicine.
