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? In the ManyClasses study by Fyfe et al. (2021), implemented in 38 classrooms with 46 instructors and N = 2081 students, no effect of delayed versus immediate feedback and study incentives was found, and preregistered moderation analyses of 40 moderators yielded no strong evidence for systematic interactions. → Lachner 2024

q2 · i? · theoretical · r3

The article reports, citing Fyfe et al. (2021), a ManyClasses within-participants study randomly assigning treatment orders per class assignment and classes to incentive conditions, implemented in "38 different classrooms" with "46 different instructors and N = 2081 students." No effect of feedback timing or incentives was detected.

"Surprisingly, the authors did not find an effect of delayed versus immediate feedback and study incentives. Preregistered moderation analyses of 40 different moderators did not obtain strong evidence for systematic interactions."
