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 teaching geometry to secondary technical school students, students in worked-example conditions benefited more from lesson variability than students in practice conditions, alongside a main effect for example-based instruction. → Atkinson 2000

q2 · i? · review · r3

The review reports, citing Paas and Van Merrienboer, a four-group experiment (low/high variability by practice/example) with secondary technical school students learning geometry, assessed by a six-item transfer posttest; the review reports 'an interaction' favoring worked-example conditions.

"Consistent with their prediction, they also found an interaction: Students in the worked-example condition benefited more from lesson variability than students in the practice condition."
