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? Approximately 8.5% of simulation runs produced negative correlations between time-on-task and achievement, explained by the norm of study constraint causing high-performing students to study less. → Brendan A. Schuetze 2024
Evidence¶
Brendan A. Schuetze 2024¶
Brendan A. Schuetze. (2024). A Computational Model of School Achievement. Educational Psychology Review. https://doi.org/10.1007/s10648-024-09853-6
q2 · i? · theoretical · r3
Simulation analysis identifying that "approximately 8.5% of the simulation data" showed negative correlations, attributed to the norm of study constraint creating an illusory negative relationship confounded with prior knowledge.
"As for the instances where there is a negative correlation (approximately 8.5% of the simulation data), this could be explained by situations where the norm of study constraint causes already high-performing students not to study much at all."
Discussion¶
Learner Variables¶
- Time and Continuity — predictor: learners who differ on it differ in outcomes
Related Claims¶
- The relationship between prior knowledge and knowledge gains shows context-dependent patterns in the CoMSA simulation — related
- The RI-CCLPM-C indicates a positive self-concept effect on achievement even when data are generated without any direct effects between self-concept and achievement — related
