Clinical Trial Summary

This study is designed to examine how the type of learning case affects the thinking of medical students in tutorial


Description:

Tutorials at Harvard Medical School use problem-based learning with written cases. Students work in groups under the supervision of a tutor who guides their exploration of the material. As students progress through the curriculum there is an opportunity to advance the complexity of the material they are presented with. Video-based patient case studies have been shown to improve critical thinking ratios in paediatric medical student problem-based learning exercises, and time spent on data exploration, theory building and theory evaluation in postgraduate residency programs. We hypothesize that video provides a stimulus that improves cognitive processing and critical thinking among medical students, as compared to working from the text-based transcript of the same case.

Intervention

Behavioral:
video case modality
Patients whose case histories are pathophysiologically illustrative will be recruited, and interviewed on video. Their stories will be edited and divided into sections, and combined with the patient's laboratory, imaging, and pathological reports when appropriate
Text case modality
Patients whose case histories are pathophysiologically illustrative will be recruited, and interviewed on video. Their stories will be edited and divided into sections, and combined with the patient's laboratory, imaging, and pathological reports when appropriate. The transcript of these video-recordings will form the basis of the text-based case presentation modality.

Outcome

Type Measure Description Time frame Safety issue
Primary Overall ratio of deep to superficial thinking Depth of thinking will be evaluated using the method of Kamin et al. Transcription of each tutorial will be divided into utterances. Each utterance will be coded for depth of thinking (deep vs. superficial). The ratio of deep to superficial thinking by case modality will be reported. Four 90-minute tutorial sessions No
Secondary Distribution of learning activities Transcription of each tutorial will be divided into utterances. Each utterance will be coded by learning domain (identification, description, exploration, integration, and application. The distribution of domains by case modality will be reported. Four 90-min tutorial sessions No
Secondary Preferences of students for each case modality Students will be surveyed regarding their preferences for video- vs. text-based case presentation modality using a Likert-scale 5 weeks No
Secondary Preferences of tutors for each case modality Tutors will be surveyed regarding their preferences for video- vs. text-based case presentation modality using a Likert-scale 5 weeks No
