Subclaims¶

q3 i? Of the teacher-level predictors tested, only the increase in teacher confidence to teach the topic was significant in both tranches; the other significant tranche-1 predictors did not replicate after multi-test correction. → Buchan 2020

Evidence¶

Buchan 2020¶

Buchan, L., Hejmadi, M., Abrahams, L. & Hurst, L. D. (2020). A RCT for assessment of active human-centred learning finds teacher-centric non-human teaching of evolution optimal. npj Science of Learning 5:19. https://doi.org/10.1038/s41539-020-00078-0

q3 · i? · causal · r2

Replication-of-significance analysis of class-level teacher predictors, isolating tranche-1 significant results and retesting them in tranche 2 with multi-test correction. Only the "increase in con fidence" predictor was significant in both tranches.

"Only one result that was signi ficant in tranche 1 was also signi ficant in tranche 2 (increase in con fidence; P = 3.40 × 10−2 and P = 2.00 × 10−3, respectively)."

Discussion¶

Learner Variables¶

• Self-Efficacy — predictor: learners who differ on it differ in outcomes
