The papers in the special series describe the role of data-based decision-making (DBDM) in improving the outcomes of students with learning disabilities based on research across Germany, the Netherlands, and the United States. The articles address multiple aspects of a model of DBDM that includes the role of teacher knowledge, skills, beliefs, and…

Although many studies have found that children with learning disabilities (LD) are less liked by peers than children without LD, the results are not unequivocal. In the present study, we investigated the social status (in terms of likeability and popularity) of children with LD by considering peer academic reputation and peer reputation of teacher…

The authors examined three instructional approaches for improving teachers' curriculum-based measurement (CBM) graph comprehension, each differing in the extent to which reading the data, interpreting the data, and linking the data to instruction were emphasized. Participants were 164 elementary school teachers who were randomly assigned to one of…

Employing a large sample of children from Dutch regular elementary schools, this study assessed the contributing and discriminating values of reading disability (RD) and attention-deficit/hyperactivity disorder (ADHD) to two types of phonological processing skills, phonemic awareness (PA) and rapid automatized naming (RAN). A second objective was…

A relationship between motor and mathematical skills has been shown by previous research. However, the question of whether subtypes can be differentiated within developmental coordination disorder (DCD) and/or mathematical learning disability (MLD) remains unresolved. In a sample of children with and without DCD and/or MLD, a data-driven…

Time perception has not been comprehensively examined in mathematics difficulties (MD). Therefore, verbal time estimation, production, and reproduction were tested in 13 individuals with MD and 16 healthy controls, matched for age, sex, and intellectual skills. Individuals with MD performed comparably to controls in time reproduction, but showed a…

In the past years, an increasing number of studies have investigated executive functions as predictors of individual differences in mathematical abilities. The present longitudinal study was designed to investigate whether the executive functions shifting, inhibition, and working memory differ between low achieving and typically achieving children…

A heterogeneous sample of 137 school-aged children with learning disabilities (IQ greater than 80) attending special needs schools was examined on the "Movement Assessment Battery for Children" (MABC). The results show that compared to the available norm scores, 52.6% of the children tested performed below the 15th percentile on manual…

The present study examined teacher attitudes toward dyslexia and the effects of these attitudes on teacher expectations and the academic achievement of students with dyslexia compared to students without learning disabilities. The attitudes of 30 regular education teachers toward dyslexia were determined using both an implicit measure and an…

Services for learning disabled adults are discussed through a comparison of their treatment in the Dutch and Danish delivery of services. Promising practices are related from a European perspective and questions are raised about the evolution of services to learning disabled adults in the United States. (Author/CL)

This study assesses the prevalence of combined reading and arithmetic disabilities in 799 Dutch schoolchildren using standardized school achievement tests. Scores of arithmetic, word recognition, reading comprehension, and spelling of children in fourth and fifth grade were used. The main interest involved the co-occurrence of word recognition and…

This study with 28 Netherlands children (mean age 9 years, 7 months) with written language disorders found that copying words from the computer screen resulted in significantly fewer spelling errors on the posttest than writing words from memory and that both these forms of practice led to fewer spelling errors than only reading the words.…

A study that investigated the relationships between exposure to lead and memory and attention in 313 boys (ages 9-12) in special-education schools in the Netherlands found blood-lead levels were higher in children with lower socioeconomic status and those with more hand-to-mouth behavior but did not influence cognitive factors.

This study examined relationships between mathematical learning difficulties (MLD) and the planning, attention, simultaneous, successive (PASS) theory of cognitive processing. PASS processes were assessed in 267 Dutch students with MLD. Results indicated students with MLD performed lower than peers on all "Cognitive Assessment System"…
