Claims

A systematic search found almost no rigorous studies contrasting online and face-to-face instruction for K–12 students: none with computable effect sizes through 2006, and only five meeting meta-analysis criteria through July 2008.

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? An extensive systematic search of literature from 1994 through 2006 found no experimental or controlled quasi-experimental K–12 studies comparing online versus face-to-face instruction with sufficient data to compute an effect size; a subsequent search through July 2008 identified just five published studies meeting meta-analysis criteria. → Means 2009

q3 · i? · quant-synthesis · r2

Systematic literature search across education, career technical, medical, higher education, corporate and military training literatures; 1,132 abstracts screened, 176 rigorous studies identified, of which just nine involved K–12 learners. The report states a subsequent search through July 2008 identified just five published studies meeting meta-analysis criteria.

"A systematic search of the research literature from 1994 through 2006 found no experimental or controlled quasi-experimental studies comparing the learning effects of online versus face-to-face instruction for K–12 students that provide sufficient data to compute an effect size."
