The purpose of this study was to examine geometry interventions for students with learning disabilities. We synthesized nine intervention studies by focusing on the geometry concepts and skills taught to students with learning disabilities, intervention types used, instructional components embedded, and the methodological rigor of the studies.…

Across many international contexts, more recent standards-based and other educational reforms have largely intended to transform teaching. Given the importance of teacher learning to such transformations, we argue that a learning-focused support approach will be essential if such reforms are to be productively taken up by schools and teachers. We…

In this meta-analysis of single-case designs, the researchers investigated the effects of word-problem instruction for students with learning disabilities in Grades 1 through 12, as reported in 20 peer-reviewed articles published between 1975 and 2020. A two-level multilevel model with a robust variance estimation method was implemented to…

This study explores the assessment of the alignment of mathematics instructional materials with the Common Core State Standards for Mathematics (CCSSM). First, focus, rigor, and coherence, identified in TIMSS studies and also established for CCSSM, were chosen as criteria of alignment. Then, the CCSSM Graph (Zimba, 2012) was used as a yardstick to…

We conducted a comprehensive review of the literature on mathematical interventions for secondary students with learning disabilities (LD) and the identified studies were analyzed in light of the mathematical practices as outlined by the Common Core State Standards Initiative (CCSSI, 2010). Results indicated that Standard 2, reason abstractly and…

This review investigates effective interventions for teaching algebra to students with learning disabilities and evaluates the complexity and alignment of skills with the Common Core State Standards in math. The review includes the results of 10 experimental and 5 single-subject designs (N = 15) producing a moderate overall effect size (g = 0.48).…

This study synthesized intervention studies focusing on instruction to improve fraction skills. Seventeen studies met the inclusion criteria: being published in English-language peer-reviewed journals or dissertations between 1975 and 2014, and targeting 3rd- through 12th-grade students struggling to learn mathematics. From the "Common Core…
