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? The approach × instructor motion interaction on BtBC was significant, with a positive instructor motion–BtBC relationship only in the scaffolding condition. → Yafeng Pan 2022

q3 · i? · causal · r2
Linear mixed-effects model on overall BtBC with Instructional Approach and continuous Instructor Motion as fixed factors and Dyad as random intercept. The model "generated a signi ficant interaction effect", with the positive association confined to the scaffolding condition; replacing instructor motion with learner motion produced no significant effects (βs < 0.05, ps > 0.06).
"This new model generated a signi ficant interaction effect ( β = 0.04, SE = 0.02, t = 2.09, p = 0.046, R2 β = 0.13), indicating that in the scaffolding condition instructor motion was positively associated with BtBC"
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 — 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 — related
- Instructors moved more when using an explanation approach than a scaffolding approach, but dyad and learner motion did not differ between approaches — related
