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 i3 Classroom-based physical activities (ES = 2.987) have huge effects on academic achievement. → Koçak 2021 q3 i3 Computer-aided teaching (ES = 1.690), material used in classroom instruction (ES = 1.269) and one-to-one laptop programs (ES = 1.249) have positive and huge effects on academic achievement. → Koçak 2021 (2) q3 i2 School mobility (ES = -.748) has medium negative effects on academic achievement. → Koçak 2021 (3)

Evidence¶

Koçak 2021¶

Koçak, Ö., Göksu, İ., & Göktaş, Y. (2021). The factors affecting academic achievement: a systematic review of meta analyses. International Online Journal of Education and Teaching, 8(1), 454-484. https://eric.ed.gov/?id=EJ1286675

q3 · i3 · quant-synthesis · r2

Systematic review of meta-analyses: 14 school variables and 17 effect sizes from 14 meta-analyses (Table 7). The review reports that "Classroom-based physical activities (ES= 2.987) were found to have huge effects on academic achievement."

"Classroom-based physical activities (ES= 2.987) were found to have huge effects on academic achievement."

Koçak 2021 (2)¶

q3 · i3 · quant-synthesis · r2

Systematic review of meta-analyses: 10 educational technology variables from 18 meta-analyses (Table 8). The review reports that "computer-aided teaching (ES= 1.690), the material used in classroom instruction (ES= 1.269) and one -to-one laptop programs (ES= 1.249) have positive and huge effects."

"computer-aided teaching (ES= 1.690), the material used in classroom instruction (ES= 1.269) and one -to-one laptop programs (ES= 1.249) have positive and huge effects on academic achievement."

Koçak 2021 (3)¶

q3 · i2 · quant-synthesis · r2

Systematic review of meta-analyses, negative-effects paragraph of the school findings (Table 7 lists school mobility ES = -.748). The review reports that "school mobility had medium effects" and school-based mentoring for adolescents had negative and very small effects.

"While school mobility had medium effects, school-based mentoring for adolescents had negative and very small effects"

Discussion¶

Across 169 meta-analyses, 254 variables with 427 effect sizes influence academic achievement; most variables have small or very small effects and none has a large, very large or huge negative effect — a broader claim this one bears on
