In a multiyear, multisite, randomized control trial, we examined the effects of comprehensive professional development designed to support teachers' data-based instruction (DBI) for students with intensive early writing needs. Teachers (N = 154; primarily special educators or intervention specialists) were assigned randomly to a treatment group (n…

The purpose of this logistic regression study was to identify predictors of teacher-reported sustained use of data-based instruction (DBI) during the COVID-19 pandemic and assess the extent to which the identified predictors explained teachers' sustained use after completing programmatic support for intensive early writing instruction. We surveyed…

Research that examines coaching approaches for special education teachers is very limited. This study, a secondary analysis of a wait-list controlled, randomized trial (106 teachers, 2,195 students, 18 schools), investigated the effects of a data-driven coaching that integrated observational assessment and performance feedback on general education…

Teachers' implementation of differentiated supplemental instruction is critical to help students with or at risk for reading-related disabilities acquire early reading and vocabulary skills. This study represents an initial investigation of whether classroom teachers' intervention fidelity (exposure, adherence, and quality) of targeted reading…

A 2-year, randomized control trial with 9th to 10th grade students with significant reading problems was provided for 50 minutes a day in small groups. Comparison students were provided an elective class and treatment students the reading intervention. Students were identified as demonstrating reading difficulties through failure on their state…

In this longitudinal study, we investigated the role of word reading and mathematical difficulties measured in 9th grade as factors for receiving educational support for learning in upper secondary education in Grades 10 to 12 (from ages 16 to 19) and furthermore as predictors of dropout from upper secondary education within 5 years after…

In this article, the authors consider the power and limitations of responsiveness-to-intervention (RTI) for reducing the need for ongoing and intensive services for the segment of the school population traditionally identified as having a learning disability in mathematics. To assess the robustness of RTI, the authors describe four studies with…

Evaluation of a Vocational Coping Training (VCT) intervention to develop job maintenance skills with 12 learning disabled high school female students indicated that subjects receiving the intervention acquired more job maintenance skills than did control subjects and were rated higher on social competence and employability.

This article examines the efficacy of current definitional perspectives on learning disabilities (LD) and related assessment models to support appropriate instructional and support services for learners of English with learning-related difficulties. A revised framework for defining LD and an associated assessment model, curriculum-based dynamic…

A review of 913 studies involving students with learning disabilities found treatment outcomes were significantly affected by the following violations: teacher effects, establishing criterion levels of instructional performance, reliance on experimental measures, using different pretest and posttest measures, using a sample heterogeneous in age,…
