Claims

Online learning effectiveness was broadly positive across content areas and learner types, but the mean effect was not significant for the seven K–12 contrasts and the learner-type moderator test was nonsignificant.

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? Online learning appeared effective for undergraduates (mean effect +0.35, p < .001) and graduate students/professionals (+0.17, p < .05); the mean effect size was not significant for the seven K–12 contrasts, and the test for learner type as a moderator variable was nonsignificant. → Means 2009

q3 · i? · quant-synthesis · r2

Learner-type moderator analysis across the 51 contrasts; the K–12 subset comprised seven contrasts from five studies. Of the K–12 contrasts, three favored blended conditions significantly, one favored face-to-face significantly, and three did not attain significance.

"Online learning appeared to be an effective option for both undergraduates (mean effect of +0.35, p < .001) and for graduate students and professionals (+0.17, p < .05) in a wide range of academic and professional studies. Though positive, the mean effect size is not significant for the seven contrasts involving K–12 students"
