How does the WWC review a study? What does it mean to meet WWC standards? Learn more in this video: youtube.com/watch?v=An9I26…

The WWC reviewed the research on the effectiveness of Reading Recovery®, a supplemental tutoring program designed to help students in grade 1 who score below grade level in reading by providing one-on-one tutoring and tailoring lessons to each student. ies.ed.gov/ncee/wwc/Inter…

@IESResearch Reading Recovery® had uncertain effects on math achievement 3 years after the intervention and on general academic achievement 10 years after the intervention.

@IESResearch There is also promising evidence that the program positively impacted writing productivity and receptive communication immediately after the intervention and writing conventions 3 years after the intervention.

@ERICinfo A summary of findings of the two studies that met standards:

The WWC identified 62 studies that investigated the effectiveness of Reading Recovery® from a literature search in @ERICinfo and other databases in July 2022. Of these 62 studies, 2 meet WWC standards.

New Intervention Report: Reading Recovery® had potentially positive effects on literacy achievement, writing productivity, & receptive communication skills and on writing conventions 3 years after the intervention. ies.ed.gov/ncee/wwc/Inter…

A new WWC intervention report finds Good Behavior Game has positive effects based on a synthesis of findings from studies that use single-case designs and group designs. ies.ed.gov/ncee/wwc/Inter…

A new WWC intervention report finds that Good Behavior Game helps improve student behavior and may improve teacher practice and student writing outcomes. ies.ed.gov/ncee/wwc/Inter…
