Subclaims¶

q3 i? Overall BtBC was significantly larger in genuine dyads than shuffled surrogates and larger under scaffolding than explanation. → Yafeng Pan 2022

Yafeng Pan, Suzanne Dikker, Yi Zhu, Cuirong Yang, Yi Hu and Pavel Goldstein. (2022). Instructor-learner body coupling reflects instruction and learning. npj Science of Learning. https://doi.org/10.1038/s41539-022-00131-0

q3 · i? · causal · r2

Motion Energy Analysis of video-recorded 8-min learning phases; genuine dyad BtBC (0.14 ± 0.02) exceeded surrogate BtBC (0.08 ± 0.01, p = 0.0002). The linear mixed-effects model showed a main effect of Instructional Approach (β = 0.02, p = 0.03, R²β = 0.19), retained when instructor motion was added as a fixed factor.

"Further analysis disclosed that the scaffolding approach (0.15 ± 0.01) was associated with significantly larger BtBC between instructors and learners than the explanation approach (0.13 ± 0.01)"

Discussion¶

Related Claims¶

• Directional leader–follower BtBC patterns decode instructional approach better than individual motion, with peak performance at non-zero time lags — related
• Instructor motion is positively associated with BtBC only during scaffolding, not explanation — related
• Learner-leading BtBC is larger under scaffolding; instructor-leading BtBC shows only a trending effect, and instructor-leading BtBC fails to predict learning under explanation — a narrower finding that bears on this claim
• Instructors moved more when using an explanation approach than a scaffolding approach, but dyad and learner motion did not differ between approaches — related
• Learners acquire concepts better under a scaffolding approach than an explanation approach — related
