Summary
Interrupted video learning with breaks or questions did not improve immediate knowledge gain for pediatric residents. However, continuous viewing or question-interrupted viewing significantly improved long-term knowledge retention.
Area of Science:
- Medical Education
- E-learning Technologies
- Pediatric Residency Training
Background:
- Optimal pedagogical strategies for e-learning in medical education are under investigation.
- Video-based e-learning is increasingly used, with potential benefits from breaks and interspersed questions.
- Research suggests breaks may improve focus, and questions may enhance knowledge acquisition and retention.
Purpose of the Study:
- To evaluate the impact of interspersed test questions and periodic breaks on immediate knowledge acquisition and 6-month retention in pediatric residents using video-based e-learning.
Main Methods:
- Pediatric residents were randomized into three groups: full video, video with logic puzzles, or video with short answer questions.
- Pre- and post-tests assessed immediate knowledge, with a retention test administered at 6 months.
- The primary outcome was the comparison of changes in test scores between groups.
Main Results:
- No significant differences in immediate knowledge gain were observed across the three learning groups.
- Knowledge retention at 6 months was significant for the full video and short answer questions groups.
- The logic puzzles group showed no significant knowledge retention compared to baseline.
Conclusions:
- Interrupted video viewing with logic puzzles or test questions did not enhance immediate knowledge gain compared to uninterrupted viewing.
- Both uninterrupted video viewing and viewing with interspersed questions led to significant long-term knowledge retention.
- These findings suggest that specific interruptions may not be beneficial for immediate learning but can support sustained knowledge retention in medical e-learning.
