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.
q2 i? Across all spatial pedagogy behavioural categories, high-experience teachers exhibited higher values in RC2 (voice quality and spectral structure) and RC3 (loudness dynamics), while low-experience teachers showed higher values in RC1, RC4 and RC5. → Yuchen Liu 2026

q2 · i? · associational · r1
Group comparison of rotated PCA component scores from 34 analysed team-teaching sessions (12 teachers, median split at 2 years), tested with Mann–Whitney U-tests corrected by FDR. The results section reports that "High-experienceteachersexhibitedhighervaluesinRC2andRC3" across behavioural categories.
"High-experienceteachersexhibitedhighervaluesinRC2andRC3.Higher RC2 values indicated differences in voice quality and spectral structure. HigherRC3valueswereassociatedwithgreaterloudnessdynamics,characterised by increased spectral flux, steeper loudness rising slopes, and a wider loudness range."

- Teacher talk differs acoustically by student cohort: undergraduate classes show higher loudness-dynamics components while postgraduate classes show higher spectral-slope and voice-quality components — related
- Collaborative tasks elicit higher loudness-dynamics components in team-teacher talk than individual tasks, which show higher spectral-slope and voice-quality components — related
