Medical students perceive better group learning processes when large classes are made to seem small

Area of Science:

• Medical Education
• Collaborative Learning
• Educational Psychology

Background:

• Large class sizes in medical schools can hinder effective small-group learning.
• Student unfamiliarity within large cohorts may impede collaborative processes.

Purpose of the Study:

• To evaluate the impact of making large classes appear smaller on students' collaborative learning.
• To assess changes in group learning dynamics without reducing enrollment.

Main Methods:

• A randomized controlled trial divided a large medical class into smaller subsets for intervention.
• Intervention groups (n=50) experienced structured small-group activities, while a control group (n=102) was integrated into a larger subset.
• Outcome measures included formal and informal group learning, and perceptions of the intervention over time.

Main Results:

• Formal group learning was perceived more positively in intervention groups starting the second year (β=0.48 increase).
• Informal learning predominantly occurred within the defined intervention subsets.
• Interviews indicated primarily positive effects with minimal negative side effects.

Conclusions:

• Structuring large medical classes to feel smaller can significantly improve collaborative learning processes.
• This strategy offers a viable approach to enhance group learning in large-scale medical education settings.
