Evidence¶
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
WWC synthesis of the two RCTs on fluency outcomes (Oral Reading Fluency test in one study; GORT-3 accuracy and rate subtests in the other). The average was "+9 percentile points across the two studies"; the rating was potentially positive because not all effects were statistically significant under WWC analysis.
"The average improvement index for fluency is +9 percentile points across the two studies, with a range of +1 to +20 percentile points across findings."
