Comparison of text and video cases in a postgraduate problem-based learning format

Area of Science:

• Medical Education
• Cognitive Science

Background:

• Problem-based learning (PBL) is a cornerstone of medical education.
• Traditional PBL often relies on text-based case vignettes.
• The impact of multimedia, specifically video, on cognitive and metacognitive processes in PBL is not fully understood.

Purpose of the Study:

• To compare the effectiveness of brief video cases versus written text descriptions in improving residents' cognitive and metacognitive processes during problem-based learning.
• To assess the impact on data exploration, theory building, theory evaluation, and metareasoning.

Main Methods:

• A study involving paediatric residents was conducted at Arhus University Hospital, Denmark.
• Participants were divided into two groups: one group analyzed a patient case vignette followed by a video, the other by a text description.
• Verbal group interactions were recorded and analyzed to quantify thinking processes.

Main Results:

• Residents who viewed a video case demonstrated statistically significant improvements in data exploration, theory building, and theory evaluation compared to those who read a text description.
• Analysis of verbal interaction clause frequencies indicated enhanced cognitive and metacognitive engagement with video cases.

Conclusions:

• Brief patient video recordings appear to be a more effective learning tool than equivalent text descriptions in enhancing key cognitive and metacognitive skills for paediatric residents in a PBL setting.
• Video cases may be a particularly valuable supplement for postgraduate paediatric training, especially in areas like movement disorders.
