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? Koedinger and Stamper (2013) demonstrated that a cognitive model built from statistical data analysis of DataShop data could be used iteratively, and their model was successful in improving learner mastery in a redesigned geometry tutor unit. → datashop-geometry

q2 · i? · design · r?
The article reports, citing Koedinger and Stamper (2013), a study where fine-grained interaction data from cognitive tutoring systems formed a cognitive model of knowledge components; the "DataShop-derived model was successful in improving learner mastery" in geometry. No effect size is printed.
"Koedinger and Stamper (2013) published work demonstrating that a cognitive model of problem-decomposition planning skills built from statistical data analysis could be used iteratively. Their DataShop-derived model was successful in improving learner mastery when used to redesign a cognitive tutor unit in geometry."
