Using cognitive diagnostic modeling (CDM), this study identified subtypes of mathematics learning disability (MLD) based on children's numerical skills and examined the language and spatial precursors of these subtypes. Participants were 99 MLD children and 420 low achievers identified from 1839 Finnish children (966 boys) who were followed from…

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 =…

We examined the efficacy of two interventions aiming to strengthen argumentative text comprehension in Greek secondary students with specific reading disability or low reading achievement of unspecified cause. The first intervention (control group, n = 29) was based on principles of systematic explicit instruction, whereas in the second one…

The number of students with reading difficulties is increasing and reading motivation is decreasing. Although serious reading problems can still persist during secondary education, most reading instruction happens in primary schools. In particular, students with learning disabilities and externalising behavioural problems are confronted with…

The purpose of this study was to examine the effects of cognitive strategies and metacognitive functions of students with learning disabilities (LD), students with low-achieving (LA), and students with average-achieving (AA) over their math problem-solving performance. The study sample consisted of 150 students with 50 students from each group.…

The purpose of this research was to conduct an exploratory study to investigate any differences in the risk of developing school refusal in students with low academic achievement and students with specific learning disorder (SLD), and moreover to compare both groups to students with high academic achievement. Furthermore, we want to investigate…

Impaired abilities in multiple domains is common in children with learning difficulties. Co-occurrence of low reading and mathematical abilities (LRLM) appears in almost every second child with learning difficulties. However, little is known regarding the neural bases of this combination. Leveraging a unique and tightly controlled sample including…

In the Arab region, several assessments are available to evaluate student skills in mathematical computations. However, none of them uses formative evaluation to guide universal screening of struggling learners or students with learning disability (LD). The current study aimed to develop mathematical computation curriculum-based measurement…

In this study, we examined the impact of a simple explicit-timing intervention on low-achieving third-grade students' ability to read more rapidly and accurately. We implemented an ABAB design with four struggling readers to establish experimental control and to evaluate the effects of the treatment in terms of the target variable. The results…

Learning or doing mathematics involves approximate quantification. The purpose of this research was to improve approximate number system acuity in primary school students with low achievement in mathematics. A quasi-experimental, pre-test, post-test design with a control group was utilized. Mathematics Achievement Test (MAT), Arithmetic…

In this research paper, we present the results from a single-case study examining the effects of the FIX strategy by Sherman and De La Paz (2015). This metacognitive instructional approach was implemented to improve the persuasive writing skills of tenth graders at high risk for school failure: students with comorbid hearing impairment and…

This article considers the topic of motivation for writing, and explores connections between writing interventions and motivation. We review the extant literature with K12 students who participated in writing interventions and examine the motivation outcomes in those studies to determine whether improvements in writing ability also led to…

Sally Reis's research interests are related to talent development in all children as well as special populations of gifted and talented students, including students with learning disabilities, gifted females, and diverse groups of talented students who are often underserved. She is also interested in extensions of the Schoolwide Enrichment Model…

Mathematical difficulties have been distinguished as mathematics learning disability (MLD) and persistent low achievement (LA). Based on 1,880 Finnish children who were followed from kindergarten (age 6) to fourth grade, this study examined the early risk factors for MLD and LA. Distinct groups of MLD (6.0% of the sample) and LA (25.7%) children…

Within the Canadian context, the two major learning disability classification systems are arguably the American Psychiatric Association's (APA) "Diagnostic and Statistical Manual of Mental Disorders" and the Learning Disabilities Association (LDAC) of Canada's "Official Definition of Learning Disabilities." Several of the more…
