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 i3 Alpha power was significantly higher (indicating lower attention) in teacher-initiated activities than in student-initiated activities, r = 0.65. → Jennie K. Grammer 2021

q2 · i3 · causal · r1
Portable EEG multilevel regression analysis of normalized occipital alpha power across four instructional activities in a college classroom; activity type varied significantly (χ2(3) = 41.39, p < 0.001). Contrast showed "alpha power was significantly higher" for teacher-initiated than student-initiated activities, r = 0.65.
"Planned contrasts revealed that alpha power was significantly higher, consistent with lower student attention, in teacher-initiated activities (lecture and video watching) than in student-initiated activities (group work and independent work), b = −0.43, t (55) = −6.32, p < 0.001, r = 0.65."
Discussion¶
Related Claims¶
- Students were less attentive during video watching than during lecture, with video showing the greatest alpha power of the four activities — a narrower finding that bears on this claim
- Time-related changes in attention within activities occurred only during independent work, not across the other activities — related
- Teacher-initiated activities also increased theta power and decreased beta and gamma power, converging with the alpha-based inference of lower wakefulness and attention — related
- No difference in alpha power between student-driven group work and independent work — related
- Observer ratings diverged from neural measures: behavioral ratings showed no teacher-initiated versus student-initiated difference and rated group work as more inattentive than independent work — related
