Subclaims¶

q3 i0 For fifth graders, the treatment had no significant effect on modeling competency at posttest or follow-up (part. η² < .01). → Hänze 2022

Evidence¶

Hänze 2022¶

Hänze, M., & Leiss, D. (2022). Using heuristic worked examples to promote solving of reality-based tasks in mathematics in lower secondary school. Instructional Science. https://doi.org/10.1007/s11251-022-09583-8

q3 · i0 · causal · r2

ANCOVA on posttest and follow-up modeling competency for 134 fifth graders with pretest covariates showed no treatment effect, "part. η 2 < .01" at posttest; equivalence was not tested.

"For fifth graders, modeling competency was not affected by the treatment; posttest: F(2,128) < 1, part. η 2 < .01; both contrasts Cworked-examples and Cprompts with p > .20); follow-up: F(2,121) < 1, part. η 2 ≤ .01; both contrasts p > .20."
