The number line is a powerful tool for supporting students' understanding of fraction magnitude. Fractions are a critical component of mathematics instruction in the elementary and intermediate grades. More specifically, understanding fraction magnitude is central to mathematical development. Yet, fractions are challenging for many students,…

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…

Reading comprehension is contingent upon the integration of various reading skills, including word reading, reading fluency, and comprehension strategies. Students who encounter challenges in both word reading and reading comprehension present an opportunity for growth across multiple reading-related domains. Recent intervention data, as…

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 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.…

Environmental awareness has become an urgent and indispensable necessity to protect the environment from risks and threats. Therefore, this study aimed to reveal the effectiveness of using cartoons in developing awareness of protecting the environment from pollution among students with learning disabilities. The study adopted the true experimental…

Supporting students with mathematics learning difficulties (MLD) as they transition from arithmetic to algebra remains a challenge within the special education and mathematics education research communities. This dissertation includes 3 manuscripts focused on how fifth graders with MLD develop algebraic understandings related to equivalence and…

Primary school students with both giftedness and learning disabilities (SGLD) in inclusive educational settings may not always receive a differentiated curriculum. Differentiation in all-level classrooms is necessary for consistently meeting the needs of SGLD. There is insufficient research on teachers' knowledge of SGLD and differentiation in…

Fractions are an important mathematical concept for elementary students. However, students with mathematics learning disabilities (MLD) struggle with learning fractions. Research has demonstrated that concrete-representational-abstract (CRA) instruction is an effective practice for students with learning and developmental disabilities. Here we…

Students with Learning disabilities and at risk for reading difficulties often face challenges in reading fluency and comprehension that impact negatively on academic success. Repeated reading (RR) is an intervention designed to increase reading fluency and comprehension skills among students at risk and diagnosed with disabilities. The purpose of…

This study explores a spatial reasoning learning trajectory of a student with difficulty in mathematics. Using a teaching experiment methodology across 15 instructional sessions, we observed how the student responded to instruction based on an established 2D shape composition learning trajectory (Sarama & Clements, 2009). A narrative…

The importance of programs that develop the thinking skills of students has been emphasized by many educational researchers. However, the majority of these studies have focused on developing these skills of gifted students and of students in public schools. Few have focused on developing and strengthening such skills in students with learning…

We respond to calls for more research to address whether and how successful professional development (PD) experiences (defined here in terms of student progress) are related to changes in teacher beliefs, specifically about effective literacy instruction for young struggling readers. We developed a measure, a Teacher Belief Score, to identify…

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…

We present the evolving fraction conceptions of two elementary school children with mathematics learning disabilities (MLD). We use qualitative analyses to capture the mathematical knowledge and experiences of each child and show how teaching was used to support advancement of their fractional reasoning. Results illustrate two viable pathways of…
