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? There was a predominance of instructor- over student-led facial joy mimicry across dyads. → Frenzel 2024
Evidence¶
Frenzel 2024¶
Frenzel, A. C., Dindar, M., Pekrun, R., Reck, C., & Marx, A. K. G. (2024). Joy is reciprocally transmitted between teachers and students: Evidence on facial mimicry in the classroom. Learning and Instruction, 91, 101896. https://doi.org/10.1016/j.learninstruc.2024.101896
q3 · i? · associational · r1
Cross-recurrence analysis of 69 instructor–student dyads compared sums of recurrences at negative versus positive lags to classify each dyad as student-led or instructor-led. The article reports "29 student-led and 40 teacher-led dyads" and 58% instructor-led.
"There were 29 student-led and 40 teacher-led dyads, so on average, 58% of the dyads were characterized as instructor-led, implying a trend for instructors to lead the joy mimicry."
Discussion¶
Related Claims¶
- Instructors' and students' facial expressions of joy cross-recurred substantially above chance during a critical time window of about -2 to +3 seconds relative to instructors' expressions — related
- Automated facial joy coding showed high sensitivity and specificity against human coding for both instructor and student videos — related
- Facially expressed joy during class correlated positively with post-session self-reported session joy for both students and instructors, though the instructor correlation did not reach significance — related
- Instructors' post-session self-reported joy correlated positively with class-average instructor–student joy mimicry, but students' self-reported joy did not — related
- Instructor–student joy mimicry was predominantly dyad-specific: only 16.4% of variance in the mimicry index was attributable to instructors — related
