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.
q3 i? ANCOVA-style univariate ANOVAs with pretests as covariates showed statistically significant gains for spatial orientation and GKT but no statistically significant gains in spatial visualization. → Akayuure et al. 2016

q3 · i? · causal · r2
Covariate-adjusted univariate ANOVAs in the quasi-experiment (experimental n = 52, control n = 42), with pretests as covariates for the dependent variables. Gains were significant for spatial orientation and GKT; the spatial visualization gain was not significant. No effect size values are printed for these adjusted contrasts.
"Furthermore, when the pretests were used as covariates in computing the univariate ANOVAs, the F ratio showed statistically significant gains for two subscales of the dependent variable: spatial orientation and GKT but no statistical significant gains in the third subscale (spatial visualization)."
Discussion¶
Learner Variables¶
- Spatial Ability — outcome: instruction changes it
