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? Univariate ANOVA showed statistically significant differences in posttest spatial orientation mean scores between the origami and conventional groups. → Akayuure et al. 2016
Evidence¶
Akayuure et al. 2016¶
Peter Akayuure, S. K. Asiedu-Addo, Victor Alebna. (2016). Investigating the Effect of Origami Instruction on Preservice Teachers’ Spatial Ability and Geometric Knowledge for Teaching. International Journal of Education in Mathematics, Science and Technology. https://doi.org/10.18404/ijemst.78424
q3 · i? · causal · r2
Univariate ANOVA on posttest scores of the quasi-experiment (experimental n = 52, control n = 42). Descriptive means favored the experimental group on spatial orientation (7.73 vs 6.43 on a 10-point max). The article reports "statistical significan t differences in posttest mean scores between groups in spatial orientation"; no effect size value is printed for this univariate contrast.
"However, there were statistical significan t differences in posttest mean scores between groups in spatial orientation and GKT ."
Discussion¶
Learner Variables¶
- Spatial Ability — outcome: instruction changes it
