Teaching Writing to At-Risk Students: The Quality of Evidence for Self-Regulated Strategy Development

Abstract

This study evaluates the quality of the research and evidence base for a writing intervention called Self-Regulated Strategy Development (SRSD; Graham & Harris, 1989; Harris & Graham, 1996) for students with and at risk for learning disabilities, using criteria for group research studies suggested by Gersten et al. (2005) and single-subject research studies suggested by Horner et al. (2005). Five experimental and quasi-experimental studies and 16 single-subject studies investigating SRSD were analyzed on numerous methodological dimensions. Both the group design and single-subject studies also met proposed standards for an evidence-based practice. The potential value of analyzing approaches and interventions using the proposed quality indicators and standards for evidence-based practices is discussed, as are implications for research and practice.
