Each of the five articles in this special issue gets "into the weeds" in terms of studying actual classroom or school implementation of evidence-based or promising practices. Virtually all confront the issue of logistics and establishing an infrastructure for ensuring adequate implementation. In general, those studies that ask teachers…

This article describes key findings from contemporary research on screening for early primary grade students in the area of mathematics. Existing studies were used to illustrate the constructs most worth measuring and the diverse strategies that researchers used to study potential measures. The authors discussed the strengths and weaknesses of…

Since 2007, when this technical report was originally issued, the assessment field has made considerable progress in developing valid and reliable screening measures for early mathematics difficulties. This update includes new research published since 2007. It focuses on valid and reliable screening measures for students in kindergarten and first…

When attempting to determine if an intervention has a causal impact, the "gold standard" of program evaluation is the randomized controlled trial (RCT). In education studies random assignment is rarely feasible at the student level, making RCTs harder to conduct. School-level assignment is more common but this often requires considerable resources…

This guide for teachers is a companion piece to the meta-analysis from the Center on Instruction, "Mathematics Instruction for Students with Learning Disabilities or Difficulty Learning Mathematics: A Synthesis of the Intervention Research". Based on the findings of this report, seven effective instructional practices were identified for teaching…

Many contemporary inservice programs set out initially to change teachers' attitudes or gain some sense of commitment from teachers prior to the implementation of a new program. However, some research studies suggest that such efforts, in and of themselves, are unlikely to bring about any real change. Serious commitment is likely to occur only…

A solid, emerging research base exists on how to provide meaningful access to the general education curriculum for students with learning disabilities. This article uses examples from research in comprehension and writing to highlight the underlying features of these empirically based approaches. The importance of multiple teaching strategies is…

Presents a conceptual framework for teaching science to students with disabilities. The framework suggests integration of explicit instruction in critical concepts, with cognitively-based approaches that emphasize problem-solving skills on real-world tasks. Implications for policy, professional development, and creation of learning environments…
