Developmental dyscalculia is a specific learning disability that is described as a heterogeneous and persistent cognitive disorder. Given the need to detect and intervene as early as possible to minimise its effects, teachers’ knowledge about symptoms, characteristics and effective intervention strategies in dyscalculia is essential. Given the lack of research about this topic and measures to evaluate teachers’ knowledge, this study aims to present a literature-based measure to evaluate knowledge about developmental dyscalculia and to investigate the predictors of this type of knowledge. Data were collected from a sample of 175 primary school teachers. The measure presented adequate psychometric properties. Teachers’ personal characteristics such as age and gender did not predict their knowledge about dyscalculia. Being a Special Education teacher predicted a higher knowledge of intervention strategies in dyscalculia and having heard about dyscalculia predicted higher knowledge about not only intervention strategies but also dyscalculia characteristics. The data are discussed, and suggestions for further studies are presented. 相似文献

The acquisition of numerical competency is regarded as imperative for quality of life and economic well-being. Many children have significant mathematical learning difficulties known as dyscalculia. The aim of this research was to systematically review the available literature for interventions with children presenting with dyscalculia in primary schools, in order to provide an evidence base of filtered information assessed for methodological rigour and coherence. The study evaluated literature from 2004 to 2014 that reported on interventions for primary school children presenting with dyscalculia. Specific databases were accessed to highlight literature for inclusion in the study. The studies were assessed at title, abstract and full text levels for quality based on the inclusion and exclusion criteria. The findings provide a base of effective interventions that can be used in the school setting for individual development with a holistic focus and present various methods of instruction for children presenting with dyscalculia. 相似文献

The first national education goal, school readiness, recognizes a need for young children to be better prepared for entry into elementary school. Many low-income children exhibit a pattern of underachievement in school mathematics. Research has revealed a developmental gap between low-income preschool children and their middle-class peers with respect to the extent of their numerical knowledge. Research has also found that many low-income children do not receive a broad base of support for mathematical development at home or in preschool. In each of two studies, we conducted a bi-generation (parent and child) mathematics intervention with Head Start families. The intervention was designed to enhance parental support for pre-kindergarten children's mathematical development. It was found that low-income parents were willing and able to support this area of their children's development once they were provided with the training to do so. The support that parents provided to their children through the intervention was clearly effective in enhancing the development of children's informal mathematical knowledge. Intervention children developed more extensive mathematical knowledge than a comparison group of low-income children. Thus, an important step toward achieving the school readiness goal can be taken by fostering low- income parents' support for young children's mathematical development. 相似文献

Abstract Individuals display a mathematics disability when their performance on standardized calculation tests or on numerical reasoning tasks is comparatively low, given their age, education and intellectual reasoning ability. Low performance due to cerebral trauma Is called acquired dyscalculia. Mathematical learning difficulties with similar features but without evidence of cerebral trauma are referred to as developmental dyscalculia. This review identifies types of developmental dyscalculia, the neuropsychological processes that are linked with them and procedures for Identifying dyscalculia. 相似文献

This study describes the development of a basic computer-based play pedagogy intervention using a dyscalculia-remedy-oriented approach such as repetition and number orientation manipulation, and the investigation of its effect on children displaying dyscalculia characteristics. This computer play was evaluated in a group of 50 seven-year-old Malaysian children, who were low achievers in mathematics subject and were divided into control and intervention group. The intervention group engaged with the newly developed computer play for an hour per day for five consecutive days, while the control group attended normal classroom learning for the same time period. Overall post-test scores indicated that children from the intervention group performed significantly better than the control group after the five-day intervention period by 57.9%. Number disorientation and arithmetic operation confusion, which are common amongst the children displaying dyscalculia characteristics, were also significantly reduced after the intervention. This implies that the children benefitted from the computer play. 相似文献

This article examines working memory functioning in children with specific developmental disorders of scholastic skills as defined by ICD-10. Ninety-seven second to fourth graders with a minimum IQ of 80 are compared using a 2 x 2 factorial (dyscalculia vs. no dyscalculia; dyslexia vs. no dyslexia) design. An extensive test battery assesses the three subcomponents of working memory described by Baddeley (1986): phonological loop, visual-spatial sketchpad, and central executive. Children with dyscalculia show deficits in visual-spatial memory; children with dyslexia show deficits in phonological and central executive functioning. When controlling for the influence of the phonological loop on the performance of the central executive, however, the effect is no longer significant. Although children with both reading and arithmetic disorders are consistently outperformed by all other groups, there is no significant interaction between the factors dyscalculia and dyslexia. 相似文献

Across two studies, we developed and tested a declarative metacognitive interview to investigate the effects of developmental
level and verbal intelligence on children's metaconceptual understanding of processes related to concept use and object categorization.
Metaconceptual knowledge developed throughout elementary school, with near ceiling scores for adults. IQ scores correlated
positively with metaconceptual interview scores for all groups of children. Study 2 confirmed a relationship between scores
on the metaconceptual interview and performance on a Twenty Questions task for which strategic performance was presumed to
depend on such knowledge, though metaconceptual knowledge was most important when IQ was lower. Implications for theory development
and hypotheses about how metaconceptual knowledge develops are discussed. 相似文献

Promoting broad and stable improvements in low-income children's numerical knowledge through playing number board games 总被引：1，自引：0，他引：1
Theoretical analyses of the development of numerical representations suggest that playing linear number board games should enhance young children's numerical knowledge. Consistent with this prediction, playing such a game for roughly 1 hr increased low-income preschoolers' (mean age = 5.4 years) proficiency on 4 diverse numerical tasks: numerical magnitude comparison, number line estimation, counting, and numeral identification. The gains remained 9 weeks later. Classmates who played an identical game, except for the squares varying in color rather than number, did not improve on any measure. Also as predicted, home experience playing number board games correlated positively with numerical knowledge. Thus, playing number board games with children from low-income backgrounds may increase their numerical knowledge at the outset of school. 相似文献

In metacognition research, many studies focused on metacognitive knowledge of preschoolers or children at the end of elementary school or secondary school, but investigations of children starting elementary school are quite limited. The present study, thus, took a closer look at children’s knowledge about mental processes and strategies in early elementary school aiming to extend findings on the respective age period. Therefore, at first, a new test that can be administered in group settings and that assesses a broad concept of children’s metacognitive knowledge in early elementary school was evaluated. Furthermore, analyses on the structure of metacognitive knowledge were carried out in cross-sectional as well as longitudinal analyses. In a longitudinal design, the new test instrument was administered to 870 children at the end of first grade and again one year later (N?=?720). Item Response models were used to evaluate the construct validity of the test. Test characteristics were checked based on different fit statistics, test fairness, and discriminant validity. In summary, the test exhibited good psychometric properties. Analyses on the dimensionality of the assessed metacognitive knowledge revealed that different strategies seemed to form rather distinct dimensions of metacognitive knowledge. However, these dimensions showed a rather homogeneous development from first to second grade. Impacts of the findings on theoretical considerations and on the theoretical understanding of metacognitive knowledge and further analyses with metacognitive competence data are discussed. 相似文献

In four carefully selected samples of 8- to 10-year old children with dyslexia (but age adequate arithmetic skills), dyscalculia (but age adequate reading skills), dyslexia/dyscalculia and controls a domain-general deficit in rapid automatized naming (RAN) was found for both dyslexia groups. Dyscalculic children exhibited a domain-specific deficit in rapid naming of quantities. This finding is in line with recent assumptions that dyscalculia is associated with a neurobiological deficit in the processing of numerosities. In the dyslexia/dyscalculia group, RAN deficits were additive, that is, the dyslexia/dyscalculia group exhibited the sum of the deficits found in the dyslexia only and dyscalculia only groups. This finding suggests that the cognitive bases of dyslexia and dyscalculia are independent from each other. Within the naming speed paradigm no differential impact of special demands on the executive functions inhibition and shifting was found for any of the four groups. 相似文献

Deficits in numerical magnitude perception characterize the mathematics learning disability developmental dyscalculia (DD), but recent studies suggest the relation stems from inhibitory control demands from incongruent visual cues in the nonsymbolic number comparison task. This study investigated the relation among magnitude perception during differing congruency conditions, executive function, and mathematics achievement measured longitudinally in children (n = 448) from ages 4 to 13. This relation was investigated across achievement groups and as it related to mathematics across the full range of achievement. Only performance on incongruent trials related to achievement. Findings indicate that executive function in a numerical context, beyond magnitude perception or executive function in a non-numerical context, relates to DD and mathematics across a wide range of achievement. 相似文献

We aimed to assess the impact of Project Spraoi: a school-based physical activity (PA) and nutrition intervention that reached 473 primary school children and 43 school staff in Cork (Ireland). Four primary schools (2 intervention, 2 control) with similar characteristics participated and for 2 school years, intervention schools were assigned an ‘Energizer’, who promoted PA and healthy eating. A subsample of children from the intervention schools (n?=?106) and matching controls (n?=?125) had measures of body mass, waist circumference, blood pressure, fitness, nutritional knowledge/attitudes and PA recorded at baseline and after 2 school years. Process evaluation techniques assessed the impact of the intervention on teachers, parents and children. Analysis of covariance revealed the intervention was associated with smaller waist circumference relative to gender and age (p?<?0.0005), slower resting heart rate (p?=?0.003) and favourable nutritional attitudes among 10 year olds. No significant change across other variables or among 6 year olds was found. Teachers, parents and children reported positive outcomes for PA behaviour and nutritional knowledge/attitudes. Project Spraoi has shown to improve heart rate and prevent further gains in fat mass amongst older aged children. The positive impact of the intervention supports the need for its continued delivery, particularly as children age. 相似文献

In a short-term longitudinal study, we investigated how domain-specific knowledge in soccer influences the amount of text recall and comprehension in elementary school and junior high school children of high and low overall aptitudes. Both level of soccer knowledge and overall aptitude were varied in a factorial design. Third, fifth, and seventh grade children were given several measures of text recall and comprehension and were retested on these measures about 1 year later. Performance was more a function of soccer knowledge than of aptitude level. 相似文献

Abstract Research indicates that a socioeconomic status-related gap in mathematical knowledge appears early and widens during early childhood. Young children from economically disadvantaged families receive less support for mathematical development both at home and in preschool. Consequently, children from different socioeconomic backgrounds enter elementary school at different levels of readiness to learn a standards-based mathematics curriculum. One approach to closing this gap is the development and implementation of effective mathematics curricula for public preschool programs enrolling economically disadvantaged children. A randomized controlled trial was conducted in 40 Head Start and state preschool classrooms, with 278 children, to determine whether a pre-kindergarten mathematics intervention was effective. Intervention teachers received training that enabled them to implement with fidelity, and a large majority of parents regularly used math activities teachers sent home. Intervention and control groups did not differ on math assessments at pretest; however, gain scores of intervention children were significantly greater than those of control children at posttest. Thus, the intervention reduced the gap in children's early mathematical knowledge. 相似文献

This randomized controlled trial or ‘true experiment' examines the effects of a school garden intervention on the science knowledge of elementary school children. Schools were randomly assigned to a group that received the garden intervention (n?=?25) or to a waitlist control group that received the garden intervention at the end of the study (n?=?24). The garden intervention consisted of both raised-bed garden kits and a series of 19 lessons. Schools, located in the US states of Arkansas, Iowa, Washington, and New York, were all low-income as defined by having 50% or more children qualifying for the federal school lunch program. Participants were students in second, fourth, and fifth grade (ages 6–12) at baseline (n?=?3,061). Science knowledge was measured using a 7-item questionnaire focused on nutritional science and plant science. The survey was administered at baseline (Fall 2011) and at three time points during the intervention (Spring 2012, Fall 2012, and Spring 2013). Garden intervention fidelity (GIF) captured the robustness or fidelity of the intervention delivered in each classroom based on both lessons delivered and garden activities. Analyses were conducted using general linear mixed models. Survey data indicated that among children in the garden intervention, science knowledge increased from baseline to follow-up more than among control group children. However, science knowledge scores were uniformly poor and gains were very modest. GIF, which takes into account the robustness of the intervention, revealed a dose–response relation with science knowledge: more robust or substantial intervention implementations corresponded to stronger treatment effects. 相似文献

This article aims to explore the symptoms and characteristics of dyscalculia. This is a qualitative study. Five experts in the field of special education took part in a focus group interview. Each expert had more than ten years of experience in their area of expertise. To determine the content validity of the protocol, three experts in special education, language and qualitative research evaluated each of the eight items. Cohen's kappa analysis was used to assess inter-rater reliability. The findings of this study indicate that 59 items have been developed, based on six constructs in the dyscalculia checklist. The six constructs were subitising, estimating, Arabic numerals, verbal numbers, arithmetic facts and calculating processes. Following the focus group interview, a new construct emerged: math anxiety. The study implies that teachers might utilise this checklist to carry out early detection of students with dyscalculia in primary schools. This will enable appropriate intervention, resulting in significant benefits for the Ministry of Education, for educators and teachers, and for the students themselves. Although this study was based in Malaysia, the results have wider implications because dyscalculia is present everywhere. 相似文献
