The Strategic Instruction Model and Xtreme Reading have been cited as Strongand the Content Literacy Continuum (CLC) was cited as being Promising in the new Evidence for ESSA website Evidence for ESSA.
Produced by the Center for Research and Reform in Education (CRRE) at Johns Hopkins University School of Education, the website provides information intended to be useful to educators and the public. Surfaced programs for every subject and grade level that meet high evidence standards that can be implemented to improve outcomes for American schools
As stated in Dr. Slavin’s blog post announcing the website, large effect sizes do not tell the entire story as large scale, randomized assignment studies result in much smaller effect sizes than smaller studies or quasi-experimental studies.
“However, unlike small and quasi-experimental studies, rigorous experiments using standardized outcome measures replicate. These effect sizes may not be enormous, but you can take them to the bank….In our secondary reading review, we found an extraordinary example of this. The University of Kansas has an array of programs for struggling readers in middle and high schools, collectively called the Strategic Instruction Model, or SIM.” ~ Robert Slavin
KUCRL’s effect sizes are derived from studies with tremendous variability; however the center has produced remarkable consistency given those contexts including:
• Studies conducted in middle schools and/or high schools
• Extra period of reading and no extra period for reading in the same study
• Some multiple year studies, and others not
• Schools settings ranged from inner-city to rural
• Studies took place across the U.S.
