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? Roughly 18% of variance in classroom computer use is attributable to between-school differences, justifying multilevel modelling. → Hermans 2008

Hermans, R., Tondeur, J., van Braak, J., & Valcke, M. (2008). The impact of primary school teachers’ educational beliefs on the classroom use of computers. Computers & Education, 51(4), 1499–1509. https://doi.org/10.1016/j.compedu.2008.02.001
q3 · i? · associational · r2
The null multilevel model for the 525 teachers nested in 68 schools showed both teacher-level and school-level variances significantly different from zero (both p < 0.001), with 18.19% of variance between schools. In the final model this fell to 16.68%.
"This results in 18.19% of the variance to be attributed to differences between schools, and 81.81% of the var- iance due to differences at the teacher level."
