This study aims to classify subtypes of mathematics disability (MD) using a novel classification method, cognitive diagnostic models (CDMs), and examine whether domain-general skills, namely, linguistic, working memory, and spatial skills, were related to the identification of the subtypes. Participants were 454 children (246 boys; age: M ± SD =…

The purpose of this study is to examine the effect of using the wrongly read and written words in sentences on correcting the reading and writing errors of students with learning disabilities. The study group of this research, which was designed according to the qualitative action research, consisted of 13 second grade students and 7 primary…

Establishing validated science programs for students with or at risk for learning disabilities requires testing treatment effects and exploring differential response patterns. This study explored whether students' initial mathematics and reading skills influenced their treatment response to a whole-class, second-grade science program called…

Achieving proficiency in core foundational oral language (OL), reading, and writing skills remains difficult for students with specific learning disabilities (SLD) and foundational OL difficulty (National Center for Educational Statistics, 2022). Despite evidence linking OL skills in grammar (morphosyntax, syntax) and vocabulary (semantics) to…

The aim of the study is to examine the effect of ABC linking activity on misspelled words in eliminating the writing errors of students with dysgraphia. The study group of the research consisted of 12 students with dysgraphia-induced writing errors who were studying in the second grade at Aybey Primary School in Usak/Türkiye in the 2021-2022…

When using response to intervention (RTI) for special education eligibility decisions, multidisciplinary teams (MDTs) may use performance level and rate of improvement (ROI) as two metrics when evaluating student responsiveness. Although examining student responsiveness to instruction is a critical component of an evaluation using RTI, previous…

We examined longitudinal relations between 1st-grade cognitive predictors (early nonverbal reasoning, processing speed, listening comprehension, working memory, calculation skill, word-problem solving, word-reading fluency, attentive behavior, and numerical cognition) and 2nd-grade academic outcomes (calculations, word-problem solving, and word…

This study aimed to evaluate the efficacy of the Repeated Reading and Visual Comprehension Program (TOGAP) developed to support the reading comprehension skills of primary school students with specific learning disabilities (SLD) in the 2nd, 3rd, and 4th grades. The research was conducted with four primary school students with SLD. The changing…

Students with dyscalculia often face significant challenges in visual memory, which is critical for mathematical learning, particularly in recognizing and differentiating geometric shapes and their properties. This study aims to explore the extent to which an action plan, tailored to the unique learning characteristics of students with…

Developmental dyscalculia (DD) is a mathematics learning disorder that affects approximately 5% to 7% of the population. This study aimed to detect the underlying domain-specific and domain-general differences between DD and typically developing (TD) children. We recruited 9-year-old primary school children to form the DD group via a 2-year…

This exploratory case study was conducted to evaluate the effectiveness of Voyager Sopris' Read Well program when implemented as a reading intervention in elementary self-contained special education classrooms. This research expands on previous research investigating the implementation of the Read Well with target populations, including those…

This single case study (multiple baselines) evaluates the efficacy of an intervention called "reading racetracks" among three eight-year-old boys with diverse backgrounds, including learning disabilities, limited language proficiency due to migration, and socio-economic challenges. Conducted over three weeks, the training demonstrated…

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…

The first purpose of this study was to examine the prevalence of risk for comorbid reading and mathematics disabilities (RMD) at start of first grade, when measured in a representative sample of 3,062 students with first-grade fluency measures (word reading; computation). The second purpose was to examine the utility of these measures for…

The increasing number of students who lack proficient reading skills is well known in Germany, as well as globally. Students with learning disabilities (LD), problem behavior, and German as a second language (L2) may face even greater hurdles. However, it is essential for teachers to provide adequate support to maintain equal educational…
