Abstract
Objectives: To determine the long-term retention of a 3-dimentional (3-D) educational computer model of the larynx to teach laryngeal anatomy and to compare it with standard written instruction (SWI).
Design: Prospective randomized controlled trial.
Setting: University education program.
Participants: One hundred health care students.
Interventions: For short-term assessment, 50 students were randomized to the 3-D model and 50 to SWI and were tested using a 20-question laryngeal test. Six months later, the same students were invited to retake the laryngeal anatomy test to examine long-term retention.
Main Outcome Measure: The score on a 20-item Web-based test that assessed the students' level of knowledge of laryngeal anatomy approximately 6 months after their initial exposure to the laryngeal anatomy teaching intervention.
Results: Sixty-two students retook the test: 3-D (n = 30) and SWI (n = 32). No significant difference was noted in mean scores (P = .54) and change in scores (P = .59) between short-and long-term retention on the laryngeal anatomy test. There was a trend toward an increase in 3-D scores in both groups (P = .07) and a significant increase in 3-D scores in the 3-D group only (P = .049).
Conclusions: A low-fidelity model (SWI) is just as effective as a high-fidelity model (3-D) in teaching laryngeal anatomy. The acquired knowledge from either educational intervention may last up to 6 months for long-term retention. This study is one of the few in medical education to examine long-term retention.
