Subclaims¶

q3 i2 For seventh graders, the treatment significantly affected both modeling competency (part. η² = .06) and strategy knowledge (part. η² = .06) at posttest, with the worked example conditions outperforming control. → Hänze 2022

q3 · i2 · causal · r2

Randomized experiment with 180 seventh graders; ANCOVA on posttest measures with pretest covariates showed the worked example conditions beat control on both modeling competency and strategy knowledge, each with "part. η2 = .06".

"The treatment affected modeling competency (F(2, 174) = 5.10, p < .01, part. η2 = .06) and strategy knowledge (F(2, 174) = 5.26, p < .01, part. η2 = .06) at posttest. Here, the Cworked-examples contrasts were significant for modeling competency (p < .05) as well as for strategy knowledge (p < .01) at posttest measurement, confirming hypothesis 1."
