Subclaims¶

q2 i? Learners profited from instruction with gestures only when the gestures conveyed a different problem-solving strategy than the one expressed in speech. → Björn B. de Koning & Huib K. Tabbers 2011

q2 · i? · review · r3

The review reports Singer and Goldin-Meadow's experiment on mathematical equivalence instruction with no gestures, matching gestures, or mismatching gestures; benefit emerged only for gestures conveying a different strategy than speech. The review attributes this to multiple modalities reducing cognitive load; no effect size is printed.

"It was found that learners profited from instruction with gestures but only when the gestures conveyed a different strategy than the one expressed in speech. These results suggest that if a problem-solving strategy needs to be learned, providing a second strategy can be helpful for learning"

Discussion¶

Related Claims¶

• Observing gestures aids recall more when gestures provide complementary rather than redundant information (review attributes this to Austin et al., 2018) — possibly the same claim (merge candidate)
• Matching modality by conveying complementary information through auditory and visual channels increases retention, transfer, and engagement — a broader claim this one bears on
• Redundant speech-gesture cooperation improves recall and social perception more than complementarity — reports the opposite
• On-screen text that duplicates the narration of a diagram can hurt learning, but spoken–written redundancy is not harmful on average and helps over spoken-only presentation in some conditions — related
• Enacting support—gestures and manipulatives—facilitates explanation quality and problem-solving, partly by adding strategies to verbal explanations — related
• Embodied action can harm learning when it adds motor demands, redundant cues, or irrelevant activity without improving understanding — related
