Jointly constructed explanation: Prompting:
Research question
How is robust learning affected by self-explanation vs. jointly constructed explanations?
Independent variables
Two variables were crossed:
- Interaction: singleton vs. dyad
- Engagement: natural vs. prompted
Hypothesis
The Interactive Hypothesis: the peers will learn more than the solo learners because they benefit from the process of negotiating meaning with a peer, of appropriating part of the peers’ perspective, of building and maintaining common ground, and of articulating their knowledge and clarifying it when the peer misunderstands.
The Coverage Hypothesis: if both peers and singletons cover the same knowledge components, then they will learn the same amount.
Dependent variables & Results
- Near transfer, immediate: problems solved during the laboratory period.
- Near transfer, retention: homework preformance on electrodynamics problems that are isomorphic to the problems solved during the laboratory period.
- Far transfer, retention: homework preformance on electrodynamics problems that are not isomorphic to the problems solved during the laboratory period.
- Acceleration of future learning: homework preformance on magnetisim problems.
Explanation
This study is part of the Interactive Communication cluster, and its hypothesis is
