Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i? Learner-leading BtBC showed a significant approach effect; instructor-leading BtBC only trended, and instructor-leading BtBC did not predict learning in the explanation approach. → 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
Exploratory analyses of directional BtBC: learner-leading showed a significant scaffolding advantage (0.15 ± 0.005 vs 0.13 ± 0.005); instructor-leading was trending (β = 0.02, p = 0.07). A separate SVR found no significant prediction of learning outcome from instructor-leading BtBC under explanation (r = 0.17, p = 0.42).
"For learner-leading BtBC (BtBC averaged across all positive lags), we observed a main effect of Instructional Approach (β = 0.02, SE = 0.01, t = 2.11, p = 0.047, R2 β = 0.17)"
Discussion¶
Related Claims¶
- Directional leader–follower BtBC patterns decode instructional approach better than individual motion, with peak performance at non-zero time lags — related
- Body-to-body coupling between instructor and learner is greater during scaffolding than explanation instruction — a broader claim this one bears on
- Learning outcome can be predicted from overall BtBC via support vector regression — related
- Instructor motion is positively associated with BtBC only during scaffolding, not explanation — related
- In the joint context, NMF-derived BtBC cluster slopes predicted learning: Cluster 1 negatively with RT slope and Cluster 2 positively with intra-brain connectivity slope — related
- 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
