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? Properly segmented text facilitates initial decoding as well as subsequent encoding and retrieval better than poorly segmented text, implying multimedia lesson segments should form internally consistent idea units. → Innwoo Park and Michael J. Hannafin 1993

q2 · i? · review · r2
The review reports, citing Frase and Schwartz (1979), that "Properly segmented text facilitates ini- tial decoding, as well as subsequent encoding and retrieval, better than poorly segmented text." It applies this to electronic media, noting multimedia systems rarely segment phrases or organize concepts into coherent idea units. The stated implication is to organize lesson segments into internally consistent idea units.
"Properly segmented text facilitates ini- tial decoding, as well as subsequent encoding and retrieval, better than poorly segmented text (Frase & Schwartz, 1979)."
