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? The Experimental Group's answers were scored significantly more complete (mean 3.55 vs 2.81 for the Control Group). → Pérez-Sanagustín 2015
Evidence¶
Pérez-Sanagustín 2015¶
Pérez-Sanagustín, M., Muñoz-Merino, P. J., Alario-Hoyos, C., Soldani, X., & Delgado Kloos, C. (2015). Lessons Learned from the Design of Situated Learning Environments to Support Collaborative Knowledge Construction. Computers & Education, 87, 70-82. https://doi.org/10.1016/j.compedu.2015.03.019
q2 · i? · causal · r2
Second mixed ANOVA of the same experiment, on the completeness dimension of teacher rubric scores (1-5 scale, three teachers' grades averaged per team per machine). The group effect was significant, F(1, 45) = 12.635, p=0.001, with a mean of "2.81" for the CG and 3.55 for the EG; the pairwise 95% interval was [0.323, 1.168].
"The mixed ANOVA analysis revealed that, in terms of completeness, the type of group also has a statistically significant effect, F(1, 45) = 12.635, p=0.001, being the difference in favor of the EG."
