Claims

Per minute of instructional time, incidental learning from context yielded roughly twelve times more words learned than an intensive direct-instruction program, though direct instruction wins for any small word set

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? Using the Multiple Choice Level 3 criterion, about .25 words were learned per minute in this study versus an average of .02 words per minute in Beck and colleagues' intensive instruction program. → Nagy 1984

q2 · i? · causal · r2

A cross-study efficiency comparison computed by the authors: Beck and colleagues' intensive program yielded "an average of .02 words are learned per minute of instruction" versus about .25 words per minute here. The authors caution that comparisons of rate of learning are fraught with difficulties.

"If one divides the increase in number of words known by the total instructional time, an average of .02 words are learned per minute of instruction. In contrast, using the Multiple Choice Level 3 criterion of knowledge (the one most similar to Beck's criterion), about .25 words were learned per minute in the current study."
