Computational skills, working memory, and conceptual knowledge in older children with mathematics learning disabilities 总被引：1，自引：0，他引：1
Knowledge and skill in multiplication were investigated for late elementary-grade students with mathematics learning disabilities (MLD), typically achieving age-matched peers, low-achieving age-matched peers, and ability-matched peers by examining multiple measures of computational skill, working memory, and conceptual knowledge. Poor multiplication fact mastery and calculation fluency and general working memory discriminated children with MLD from typically achieving age-matched peers. Furthermore, children with MLD were slower in executing backup procedures than typically achieving age-matched peers. The performance of children with MLD on multiple measures of multiplication skill and knowledge was most similar to that of ability-matched younger children. MLD may be due to difficulties in computational skills and working memory. Implications for the diagnosis and remediation of MLD are discussed. 相似文献

Fact retrieval deficits in low achieving children and children with mathematical learning disability
Using 4 years of mathematics achievement scores, groups of typically achieving children (n = 101) and low achieving children with mild (LA-mild fact retrieval; n = 97) and severe (LA-severe fact retrieval; n = 18) fact retrieval deficits and mathematically learning disabled children (MLD; n = 15) were identified. Multilevel models contrasted developing retrieval competence from second to fourth grade with developing competence in executing arithmetic procedures, in fluency of processing quantities represented by Arabic numerals and sets of objects, and in representing quantity on a number line. The retrieval deficits of LA-severe fact retrieval children were at least as debilitating as those of the children with MLD and showed less across-grade improvement. The deficits were characterized by the retrieval of counting string associates while attempting to remember addition facts, suggesting poor inhibition of irrelevant information during the retrieval process. This suggests a very specific form of working memory deficit, one that is not captured by many typically used working memory tasks. Moreover, these deficits were not related to procedural competence or performance on the other mathematical tasks, nor were they related to verbal or nonverbal intelligence, reading ability, or speed of processing, nor would they be identifiable with standard untimed mathematics achievement tests. 相似文献

The purpose of this study was to examine longitudinally the development of letter-sound and letter-name knowledge and their
relation to each other and to various aspects of phonological awareness in a sample of Greek kindergarten children who did
not know how to read. One hundred twenty children aged 58–69 months were assessed on letter-sound and letter-name knowledge,
as well as on phonological awareness skills at the beginning, the middle and the end of kindergarten. The findings indicated
that: (a) kindergarten children knew more letter-sounds than letter-names in almost every case across the assessment points;
(b) letter-sound knowledge predicted letter-name knowledge slightly better than vice versa; (c) phonological awareness was
associated directly with later letter-sound and letter-name knowledge, and (d) the bidirectional hypothesis between phonological
awareness and letters knowledge was not confirmed. 相似文献

This study recruited 428 Singaporean children at risk of math learning difficulties (MLD; Mage = 83.9 months, SDage = 4.35 months; 41% female). Using a factor mixture model that considered both quantitative and qualitative differences in math ability, two qualitatively different groups were identified: one with generalized difficulties across different math skills and the other with more focal difficulties in arithmetic fluency. Reading, working memory capacity, and numeracy (number line estimation skills and numerical discrimination) uniquely explained group membership. Children within each group differed in the extent of difficulties they exhibited, with numeracy variables differentially contributing to math ability in each group. Findings speak against a dimensional view of MLD and underscore the conceptual limitations of using basic numeracy performance to profile learning difficulties. 相似文献

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 were identified on the basis of their mathematics performance between first and fourth grades with latent class growth modeling. Impairment in the same set of cognitive skills, including language, spatial, and counting skills, was found to underlie MLD and LA. The finding highlights the importance of monitoring mathematical development across the early grades and identifying early cognitive precursors of MLD and LA for screening and intervention efforts. 相似文献

Cognitive mechanisms underlying achievement deficits in children with mathematical learning disability 总被引：4，自引：0，他引：4
Using strict and lenient mathematics achievement cutoff scores to define a learning disability, respective groups of children who are math disabled (MLD, n=15) and low achieving (LA, n=44) were identified. These groups and a group of typically achieving (TA, n=46) children were administered a battery of mathematical cognition, working memory, and speed of processing measures (M=6 years). The children with MLD showed deficits across all math cognition tasks, many of which were partially or fully mediated by working memory or speed of processing. Compared with the TA group, the LA children were less fluent in processing numerical information and knew fewer addition facts. Implications for defining MLD and identifying underlying cognitive deficits are discussed. 相似文献

Cognitive characteristics of children with mathematics learning disability (MLD) vary as a function of the cutoff criterion used to define MLD 总被引：1，自引：0，他引：1
Researchers of mathematics learning disability (MLD) commonly use cutoff scores to determine which participants have MLD. Some researchers apply more restrictive cutoffs than others (e.g., performance below the 10th vs. below the 35th percentile). Different cutoffs may lead to groups of children that differ in their profile of math and related skills, including reading, visual-spatial, and working memory skills. The present study assesses the characteristics of children with MLD based on varying MLD definitions of math performance either below the 10th percentile (n = 22) or between the 11th and 25th percentile (n = 42) on the Test of Early Math Ability, second edition (TEMA-2). Initial starting levels and growth rates for math and related skills were examined in these two MLD groups relative to a comparison group (n = 146) whose TEMA-2 performance exceeded the 25th percentile. Between kindergarten and third grade, differences emerged in the starting level and growth rate, suggesting qualitative differences among the three groups. Despite some similarities, qualitative group differences were also observed in the profiles of math-related skills across groups. These results highlight differences in student characteristics based on the definition of MLD and illustrate the value of examining skill areas associated with math performance in addition to math performance itself. 相似文献

This study examines visual and spatial working memory skills in 35 third to fifth graders with both mathematics learning disabilities (MLD) and poor problem-solving skills and 35 of their peers with typical development (TD) on tasks involving both low and high attentional control. Results revealed that children with MLD, relative to TD children, failed spatial working memory tasks that had either low or high attentional demands but did not fail the visual tasks. In addition, children with MLD made more intrusion errors in the spatial working memory tasks requiring high attentional control than did their TD peers. Finally, as a post hoc analysis the sample of MLD was divided in two: children with severe MLD and children with low mathematical achievement. Results showed that only children with severe MLD failed in spatial working memory (WM) tasks if compared with children with low mathematical achievement and TD. The findings are discussed on the basis of their theoretical and clinical implications, in particular considering that children with MLD can benefit from spatial WM processes to solve arithmetic word problems, which involves the ability to both maintain and manipulate relevant information. 相似文献

A successful transition from kindergarten to 1st grade requires a positive combination of multiple dimensions of child competence. Using latent class analysis, we simultaneously examined the academic skills, work attitude, and social/behavioral competence of a large sample of Dutch kindergarten children to identify profiles of kindergarten competence. We tested the predictive power of the profiles by means of multivariate multilevel analyses with language, arithmetic, and work attitude scores as outcome variables. Research Findings: Five profiles of children with distinctive combinations of skills were identified. The results showed that the profile solution forms a significant basis on which to predict later performance. In particular, children in the 2 profiles with the highest kindergarten competence levels perform significantly better in Grade 1 than children with less advantageous skill sets, an effect that tends to increase in magnitude at the end of Grade 2. Practice or Policy: We suggest a practical validation of these profiles to be used as tools for tailoring learning opportunities in kindergarten according to children's skill sets. 相似文献

The study sought out to extend our knowledge regarding the origin of mathematical learning disabilities (MLD) in children by testing different hypotheses in the same samples of children. Different aspects of cognitive functions and number processing were assessed in fifth- and sixth-graders (11–13 years old) with MLD and compared to controls. The MLD group displayed weaknesses with most aspects of number processing (e.g., subitizing, symbolic number comparison, number-line estimation) and two cognitive functions (e.g., visual–spatial working memory). These findings favor the defective approximate number system (ANS) hypothesis, but do not fit well with the access deficit hypothesis. Support is also provided for the defective object-tracking system (OTS) hypothesis, the domain general cognitive deficit hypothesis and to some extent the defective numerosity-coding hypothesis. The study suggests that MLD might be caused by multiple deficits and not a single core deficit. 相似文献

One year after participating in the Research‐based, Developmentally Informed (REDI) intervention or “usual practice” Head Start, the learning and behavioral outcomes of 356 children (17% Hispanic, 25% African American; 54% girls; Mage = 4.59 years at initial assessment) were assessed. In addition, their 202 kindergarten classrooms were evaluated on quality of teacher–student interactions, emphasis on reading instruction, and school‐level student achievement. Hierarchical linear analyses revealed that the REDI intervention promoted kindergarten phonemic decoding skills, learning engagement, and competent social problem‐solving skills, and reduced aggressive–disruptive behavior. Intervention effects on social competence and inattention were moderated by kindergarten context, with effects strongest when children entered schools with low student achievement. Implications are discussed for developmental models of school readiness and early educational programs. 相似文献

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 preschool (age 6) to fourth grade (2007–2011). Five subtypes were identified: the arithmetic fluency deficit only subtype, the counting deficit subtype, the pervasive deficit subtype, the symbolic deficit subtype, and the counting and concept deficit subtype. Different subtypes depended on different constellations of language and spatial deficits. Findings highlight the effectiveness of CDM in identifying MLD subtypes and underscore the importance of understanding the specific deficits and antecedents of the subtypes. 相似文献

Research Findings. The present study examined relations between social-cognitive skills, aggression, and social competence using teacher questionnaires and tabletop tasks with preschool and kindergarten children. It was hypothesized that the acquisition of a theory of “mind”, as indexed by an understanding of false beliefs, might be related to social behavior for this age group. Overall, results indicated that both generation of forceful solutions in a traditional social-problem solving task and performance on the false belief tasks were significantly related to social competence, after controlling for the effects of age, language comprehension, and teacher ratings of aggression. In addition, theory of mind understanding was a better predictor of social competence than performance on a more traditional social information-processing task that involved the generation of alternative solutions to interpersonal problems. Practice. The implications of these findings for preschool and kindergarten peer relations and their potential relevance to treatment of deficits in social skills are discussed. Specifically, training in an understanding of counterfactual thinking (e.g., through increased and structured opportunities to engage in pretend play and storytelling) may enhance preschooler social skills. 相似文献

The present study compared the relative effects of 2 educational programs on kindergarten children. The experimental group took part in a numeracy-specific program, which focused on conceptual knowledge. Children were taught basic numerical skills such as understanding and handling numbers and their relations as well as counting principles. The control group participated in a more general program which involved training in procedural skills. Results revealed significant learning effects in the children who participated in the numeracy program particularly for counting sequences and mental calculation. Since neither group was explicitly trained in mental calculation, our findings suggest that a learning transfer took place in the experimental group. 相似文献

The impact of kindergarten learning-related skills on academic trajectories at the end of elementary school 总被引：4，自引：1，他引：4

Recent research indicates that children's learning-related skills (including self-regulation and social competence) contribute to early school success. The present study investigated the relation of kindergarten learning-related skills to reading and math trajectories in 538 children between kindergarten and sixth grade, and examined how children with poor learning-related skills fared throughout elementary school on reading and math. Latent growth curves indicated that learning-related skills had a unique effect on children's reading and math scores between kindergarten and sixth grade and predicted growth in reading and math between kindergarten and second grade. In addition, children with poor learning-related skills performed lower than their higher-rated peers on measures of reading and mathematics between kindergarten and sixth grade, with the gap widening between kindergarten and second grade. Between third and sixth grade, this gap persisted but did not widen. Discussion focuses on the importance of early learning-related skills as a component in children's academic trajectories throughout elementary school and the need for early intervention focusing on children's self-regulation and social competence. 相似文献

Recently, research has begun to identify cognitive and social-emotional predictors of early academic success. Yet few studies have examined the mechanisms by which children's social-emotional skills are associated with later academic success. The present study examines the associations between preschool emotion knowledge, kindergarten attention skills, and first grade academic competence in a sample of mostly disadvantaged children. Results indicate that attention during kindergarten is a significant mediator of this association, even after accounting for the effects of maternal education, family income, and children's age, sex, and receptive vocabulary skills. The findings provide further support for the implementation of preventive curricula that focus on both social and emotional development as well as attentional development as one strategy for improving future academic success in young children. 相似文献

Repetitive shared book experiences provided by public school kindergarten staff were used to improve literacy competence and preparation for formal first-grade reading instruction. The entire 1983–1984 kindergarten population (N = 228) of a rural, racially mixed, southeastern school district in South Carolina received eight shared reading experiences for each of three classic children's books. The shared book experience is defined as the situation in which a group of two or three children sit close enough to an adult to see the print as a book is read. Readings were provided by teachers, teacher aides, school volunteers, older students, and audiotapes. The children were individually administered the South Carolina State Department of Education's mandated Cognitive Skills Assessment Battery (Boehm & Slater, 1974) during the first 3 weeks of first grade. The control group, composed of the 1982–1983 kindergarten population (N = 269), had 73% of its children at or above the state cutoff for first-grade readiness, and the experimental group had 83% at or above the cutoff. (T = 22.2, p < .01). In addition, the school district staff reported a 10% increase in the number of children being placed in “top” reading groups. Repetitive, personal shared book experiences were found to enhance literacy awareness and competence, to improve preparation for formal first grade, and to broaden children's literacy interests. 相似文献

Early feelings about school and later academic outcomes of children with special needs living in poverty 总被引：1，自引：0，他引：1
In this investigation we examined the relation of children's reported feelings about school during kindergarten or first grade to their academic achievement at the end of fifth grade. Participants were children (N = 103) who lived in poverty during early childhood and who were placed on individualized education programs (IEPs) during their elementary school years. Results indicated that early feelings about school predicted fifth-grade outcomes above and beyond predictions based on an assessment of receptive language at age 5. Specifically, general positive feelings about school predicted higher fifth-grade literacy skills whereas feelings of greater competence in academics predicted higher fifth-grade math skills. The findings have implications for interventions with young children who have special learning needs, live in poverty, and report early ambivalent or negative feelings about school. 相似文献
