Subclaims¶

q2 i? Student-teacher coupling showed no predictive effect on score changes at lags of 1 to 4 waves. → Xiaomeng Xu 2026 q2 i? Cross-subject analyses found no significant effects in either direction, indicating subject-specific coupling dynamics. → Xiaomeng Xu 2026 (2)

Xiaomeng Xu, Dan Zhang & Yu Zhang. (2026). Student teacher inter brain coupling forecast cross semester academic fluctuation in real world classrooms. npj Science of Learning. https://doi.org/10.1038/s41539-026-00421-x

q2 · i? · associational · r2

Lag analysis forecasting Δscores at lags from 0 to 4 waves in the longitudinal dataset; only lag-0 results were significant and displayed. The authors interpret this as coupling influence being limited to contiguous academic terms.

"The results suggests that student -teacher coupling does not have a predictive effect on subsequent changes in academic performance."

q2 · i? · associational · r2

Cross-subject analysis using Chinese-class TI to predict math performance and vice versa, under both dynamic and static models. No significant effects emerged in either direction, suggesting coupling effects "reflect subject-specific dynamics of classroom interaction."

"As shown in Figure S5, no significant effects were found in either direction."

Related Claims¶

• Within-student increases in high-beta student-teacher inter-brain coupling predict subsequent improvement in both Chinese and math scores — reports the opposite
• Static same-wave student-teacher inter-brain coupling is negatively associated with concurrent math performance — related
• Peer-based inter-brain coupling predicts math improvement only via class-average coupling and shows subject-specific static patterns — related
• The coupling-performance relationship differs across baseline achievement groups — related
