Subclaims¶

q3 i? WWC re-analysis of the Rashotte, MacPhee, and Torgesen (2001) randomized trial confirmed statistically significant differences on the WRMT–R word attack, TOWRE phonetic decoding efficiency, CTOPP blending words, and CTOPP segmenting words outcomes. → What Works Clearinghouse 2007

What Works Clearinghouse, U.S. Department of Education. (2007). WWC Intervention Report: SpellRead™. https://ies.ed.gov/ncee/wwc

q3 · i? · quant-synthesis · r1

Randomized trial of 47 first- and second-grade students in Newfoundland; the review reports that WWC analysis "confirmed statistically significant differences for only four of the outcomes", though study authors had reported six significant effects. No standardized effect size is printed for the individual outcomes.

"However, the WWC analysis confirmed statistically significant differences for only four of the outcomes (WRMT–R word attack subtest, the TOWRE phonetic decoding efficiency subtest, and the CTOPP blending words and segmenting words subtests)."

Related Claims¶

• In the Rashotte, MacPhee, and Torgesen (2001) RCT, SpellRead™ produced statistically significant positive effects on alphabetics and reading fluency for fifth- and sixth-grade struggling readers after eight weeks — related
• SpellRead™ shows potentially positive effects on alphabetics for adolescent readers, with an average improvement index of +23 across two studies — a broader claim this one bears on
• REDI effects largely fade by end of kindergarten, with significant positive effects only on TOWRE Phonetic Decoding Efficiency — related
• Individual differences in decoding growth persisted across elementary school for timed pseudo-word decoding but were absent throughout for CTOPP Blending Words — related
