The impact of working memory capacity on collaborative learning in elementary school students

Area of Science:

• Cognitive Psychology
• Educational Psychology
• Learning Sciences

Background:

• Working memory capacity is crucial for learning but its role in collaborative learning is understudied.
• Previous research has not directly investigated how individual working memory capacity affects collaborative learning effectiveness.

Purpose of the Study:

• To examine the impact of working memory capacity on collaborative learning using worked examples.
• To investigate how member and group working memory capacities influence heterogeneous collaborative learning outcomes.

Main Methods:

• Experiment 1: 2x2 factorial design comparing collaborative vs. individual learning for high and low working memory capacity 4th graders.
• Experiment 2: 2x2 factorial design exploring member and group capacity effects in heterogeneous collaborative learning.

Main Results:

• High-capacity learners showed improved performance and less resource depletion in collaborative settings.
• Low-capacity learners did not benefit from collaborative learning in Experiment 1.
• In heterogeneous groups, high-capacity groups improved performance for all members; high-capacity members benefited more in high-capacity groups.

Conclusions:

• Working memory capacity significantly moderates the effectiveness of collaborative learning.
• Collaborative learning primarily benefits high-capacity learners; low-capacity learners require specific group compositions for partial gains.
• Findings inform the design of more effective heterogeneous collaborative learning environments.
