The purpose of this study was to investigate the effects of the concrete-representational-abstract--integrated (CRA-I) sequence on students with learning disabilities' performance when learning fraction and decimal concepts. Three elementary-level students in Grades 4 and 6 participated in a single-case multiple probe across behaviors study. The…

This study reports the effects of instruction of elementary students in a complex package of social and academic skills designed for use in cooperative groups while studying important information in inclusive general education classes. Twenty-five teachers and 519 fourth and fifth graders, including 45 students with learning disabilities (LD),…

One of the most persistent areas of difficulty in mathematics for children with learning disabilities (LDs) and difficulties is fractions. We report the development and initial testing of an intervention designed to increase access to and advancement in conceptual understanding. Our asset-based theory of change--a tested and confirmed learning…

The purpose of this registered report study was to determine the effects of explicit text structure instruction on the expository text comprehension of students with language and learning disabilities (LLD) using a multiple baseline design across conditions (e.g., compare-contrast and cause-effect) and participants. Participants included four…

Engagement and academic achievement are generally correlated among elementary school students without learning disabilities (LDs). However, it is unclear if this pattern holds for students with LDs, who have lower achievement and engagement than their peers. This study examined whether links between achievement and student-reported behavioral…

The extent to which reading achievement is causally impacted by eligibility for special education services due to a learning disability (LD) or speech or language impairment (SLI) is currently unclear. In this registered report, we analyzed U.S. national data from the Early Childhood Longitudinal Study--Kindergarten Cohort of 2010-2011 (ECLS-K:…

Informed by a constructivist-based, student-adaptive pedagogical approach, this study explores the benefits of teacher-learner discourse moves for the mathematics learning of students with learning disabilities (LD). During a constructivist teaching experiment for nurturing the multiplicative reasoning and problem solving of five third-grade…

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.…

This meta-analysis assessed the effect of word-problem-solving interventions on the word-problem-solving accuracy of students identified as having a learning disability (LD) or at risk for an LD in kindergarten to the sixth grade. Eighteen randomized control group designed studies met the inclusion criteria. Overall, word-problem-solving…

State standards include fluent use of standard computational algorithms. However, learning and using them require conceptual understanding of numbers and operations. Previous research using the concrete--representational--abstract (CRA) sequence has been effective in teaching computational algorithms to students at risk of and students with…

We investigated the effect of conceptual transparency in the physical structure of manipulatives on place-value understanding in typically developing children and those at risk for mathematics learning disabilities. Second graders were randomly assigned to one of three manipulatives conditions: (a) attachable beads that did not make the…

Self-efficacious children are expected to be more task-focused in challenging achievement situations and consequently have better chances of overcoming learning difficulties than children who have lower self-efficacy. The present study investigates this presumption with Finnish-speaking first graders struggling with reading acquisition (N = 285).…

Research has suggested that the relationship between previous academic achievement and student variables is mediated by parent and teacher expectations of the child's ability and future success. The goal of this study was to analyze the mediating role of teachers' expectations and teachers' perceptions of parents' expectations between previous…

When a student struggles with a mathematics task, adults may rephrase or expand initial task instructions to clarify instructions or scaffold problem solving. Yet expanded instructions may not benefit all children, especially children with a mathematics learning disability (MLD). Here, we explore whether expanded instructions differentially affect…

There are still many unanswered questions regarding the application of response to intervention (RTI) to making eligibility decisions for specific learning disabilities (SLD). Both U.S. federal regulations and research support that students identified with SLD using RTI should be deficient in both level of academic functioning and rate of growth…
