The article reviews three studies (EC 600 064-066) evaluating the effectiveness of using Irlen tinted lenses or overlays with reading-disabled persons. It is concluded that carefully designed and controlled studies do not currently lend support to the Irlen hypothesis. (DB)

A meta-analysis of instructional research with students with learning disabilities in the domains of word recognition and reading comprehension indicates effect sizes for comprehension measures were higher when studies included derivatives of both cognitive and direct instruction, whereas effect sizes were higher for word recognition when studies…

Meta-analysis on 25 studies found that both methodologically strong and weak studies demonstrated significant behavioral deficits of children with learning disabilities in 5 areas: on-task behavior, off-task behavior, conduct disorders, distractibility, and shy/withdrawn behavior. Effect sizes clustered around 1 standard deviation. (Author/DB)

This article applies results of a previous meta-analysis of effective instructional practices with adolescents who have learning disabilities focusing on the factor, "Organization/Explicit," which contributed significant variance to effect size. This factor included the important instructional components of advance organization and explicit…

This article summarizes single-subject design intervention studies that include students with learning disabilities. Effect sizes of 85 studies were analyzed across instructional domains, sample characteristics, intervention parameters, and methodological procedures. Findings are supportive of the pervasive influence of cognitive strategy and…

Reviews data from 13 major follow-up studies of youth with learning disabilities regarding postschool outcomes, postsecondary education, and employment, with attention to gender differences. Notes contradictions in the findings and identifies five methodological issues that appear to influence the conduct and interpretation of follow-up studies. A…

This meta-analysis looked at outcomes of school-based interventions aimed at enhancing the self-concept of students with learning disabilities, specifically effect sizes in relation to students' self-concepts prior to the intervention. Results indicated that only students with documented low self-concept benefited significantly from intervention.…
