Using technology to support children with dyscalculia in pre-primary and primary school: insights, challenges and opportunities

Mathematics difficulties are common in both children and adults, and they can have a great impact on people's lives. A specific learning disorder in mathematics (SLDM or developmental dyscalculia) is a special case of persistent mathematics difficulties, where the problems with maths cannot be attributed to environmental factors, intellectual disability, or mental, neurological or physical disorders. The aim of the current study was to estimate the prevalence rate of SLDM, any gender differences in SLDM, and the most common comorbid conditions. The DSM-5 provides details regarding these only for specific learning disorders in general, but not specifically for SLDM. We also compared the prevalence rates obtained on the basis of the DSM-IV and DSM-5 criteria. We investigated the performance of 2,421 primary school children on standardized tests of mathematics, English, and IQ, and several demographic factors over the primary school years. We applied the DSM-5 diagnostic criteria to identify children with a potential diagnosis of SLDM. Six per cent of our sample had persistent, severe difficulties with mathematics, and, after applying the exclusion criteria, 5.7% were identified as having an SLDM profile. Both persistent maths difficulties and consistently exceptionally high performance in maths were equally common in males and females. About half of the children with an SLDM profile had some form of language or communication difficulty. Some of these children also had a diagnosis of autism, social, emotional, and behavioural difficulties or attention deficit and hyperactivity disorder. Our findings have important implications for research and intervention purposes, which we discuss in the study.

Developmental Dyscalculia (DD) is characterised by persistent difficulties in learning mathematical skills, which usually becomes apparent in the early years of schooling. Traditionally, DD is known to affect children’s arithmetic processing, whilst other domains of mathematics receive much less research attention. Nevertheless, contemporary diagnostic guidelines suggest that DD is linked to widespread and diverse difficulties, both within and outside of the domain of numbers. This study examined the performance (i.e., accuracy and number of questions attempted) of children on a curriculum-based mathematics assessment, considering the effect of content domains, question format (i.e., multiple-choice questions vs. constructed response questions) and test half. Participants were forty children aged 8 to 11 years old with DD (n = 20) and a carefully matched control group of typically developing children (n = 20) from primary schools in Northern Ireland. Results revealed that the DD group achieved significantly lower scores than the control group across all areas of the curriculum, and the magnitude of group differences was similar across all content domains. These findings indicate that performance in content domains other than in arithmetic may be equally informative in supporting the identification of children with DD. In addition, we found that using multiple-choice questions may support learners with DD in achieving the best outcome, and, thus, could be useful for assessing mathematics skills in dyscalculic children in classroom contexts. Nevertheless, constructed response questions may show the greatest sensitivity to identifying learners at risk, and could be the most useful in diagnostic settings.

In 1985 significant school reforms prolonged the duration of primary schooling in Kenya from 7 to 8 years. The goal of the reforms, amongst other changes, was to increase skills and consequently increase earnings for workers with primary school education. This paper explores whether the extra year of primary schooling may have enhanced skills and consequently increased relative wages for workers with the additional eighth year of primary schooling. Such an analysis is important for two reasons. First, we are the first to gauge the impact of the reforms on relative wage changes for workers with primary school education in a developing country setting particularly in sub-Saharan Africa. Second, and more importantly, such an inquiry is warranted because by focusing solely on relative wage changes for primary school educated workers, we consider whether the reforms did actually increase relative wages for workers with more i.e. 8 years of primary schooling without the confounding effects of post primary school education (i.e. secondary, tertiary, middle-level and university education) on earnings. Our empirical technique takes advantage of exogenous variation induced by the new policy and employs a data-driven pseudo regression discontinuity design to consider whether the new school reforms did indeed create a wage discontinuity for workers with 7 and 8 years of primary school education at the cutoff point in 1985. Utilizing data from the 2004/2005 Kenya Integrated Household Budget Survey, our findings shed new light. We find that although the relative wage for workers with 7 years of primary schooling is marginally higher, the trajectory of the age-earnings profile is relatively steeper for workers with the 8th year of primary schooling. This finding, consistent with human capital theory, suggests that workers with the extra year of primary schooling would earn a higher future relative wage. As such, from a policy standpoint, increasing the duration of primary school education may be a necessary but not a sufficient condition for increasing relative wages for workers with the added year of primary schooling at least in the short run. Short run underlying factors, such as differences in age, years of labor market experience, compounded by transition bottlenecks (not considered in this paper but widely discussed in the literature) may inhibit an instantaneous wage increase for workers with the added year of primary schooling.

Issues of pedagogy are critical in all aspects of early childhood education. Early childhood mathematics is no exception. There is now a great deal of guidance available to teachers in terms of high‐quality early childhood mathematics teaching. Consequently, the characteristics of high‐quality early childhood mathematics education are clearly identifiable. Issues such as building on young children’s prior‐to‐school knowledge; engaging children in general mathematical processes; and assessing and documenting children’s learning are some of the key aspects of high‐quality early childhood mathematics education. The extent to which teachers of four‐ and five‐year‐old children in primary schools in Ireland incorporate current pedagogical guidance in early childhood mathematics education was explored in 2007 in a nationally representative questionnaire survey of teachers of four‐ and five‐year‐old children attending primary schools. This paper presents some of the findings of the study in relation to teachers’ self‐reported challenges, difficulties and priorities in teaching early childhood mathematics. Implications are drawn for professional development, curriculum guidance and educational policy.

Bullying victimization in childhood and adolescence is widely acknowledged for its detrimental effects on mental health and loneliness in young adulthood. However, the influence of onset time when bullying happens (in primary and/or secondary school) and of distinct forms of bullying remain underexplored. The study aims to explore the associations between seven forms of victimization (being teased or called nasty names; rumor spreading; physical harm; threat; property damage; robbery; social exclusion) during university students' primary and secondary school years and their current mental health and loneliness in China. A total of 684 university students (mean age = 19.05, SD = 1.56) completed Depression, Anxiety, Stress Scale (DASS-21), UCLA Loneliness Scale, and Retrospective Bullying Questionnaire, which involves recollection of bullying victimization during primary and secondary school years. Stable victim (those who experienced bullying victimization during both primary and secondary school years) was most strongly associated with current higher levels of depression, anxiety, stress, and loneliness. Different forms of bullying victimization in primary and secondary school years were independently associated with mental health and loneliness. Specifically, rumor spreading in secondary school strongly predicted depression, anxiety, and stress, while social exclusion in primary school was closely linked to depression, anxiety, and loneliness. These findings underscore the long-term psychological impact of various forms of bullying victimization experienced in primary and secondary school years and highlight the importance of targeted interventions that address specific types of bullying in primary and secondary school years to mitigate their enduring effects on mental health in young adulthood.

This study performed comparative analyses in two pediatric cohorts to identify dietary patterns during primary school years and examined their relevance to body composition development. Nutritional and anthropometric data at the beginning of primary school and two or four years later were available from 298 and 372 participants of IDEFICS-Germany (Identification and prevention of Dietary-induced and lifestyle-induced health Effects In Children and infants Study) and the KOPS (Kiel Obesity Prevention Study) cohort, respectively. Principal component analyses (PCA) and reduced rank regression (RRR) were used to identify dietary patterns at baseline and patterns of change in food group intake during primary school years. RRR extracted patterns explaining variations in changes in body mass index (BMI), fat mass index (FMI), and waist-to-height-ratio (WtHR). Associations between pattern adherence and excess gain in BMI, FMI, or WtHR (>75th percentile) during primary school years were examined using logistic regression. Among PCA patterns, only a change towards a more Mediterranean food choice during primary school years were associated with a favorable body composition development in IDEFICS-Germany (p < 0.05). In KOPS, RRR patterns characterized by a frequent consumption of fast foods or starchy carbohydrate foods were consistently associated with an excess gain in BMI and WtHR (all p < 0.005). In IDEFICS-Germany, excess gain in BMI, FMI, and WtHR were predicted by a frequent consumption of nuts, meat, and pizza at baseline and a decrease in the consumption frequency of protein sources and snack carbohydrates during primary school years (all p < 0.01). The study confirms an adverse impact of fast food consumption on body composition during primary school years. Combinations of protein and carbohydrate sources deserve further investigation.

Twenty-one children aged 5-6 years (mean age: 71.2 months; S.D. = 2.7) were videotaped in 4 different kindergartens throughout the school day for a period of one week. Eighteen of these children were then followed up after the summer holidays and videotaped for one week while attending the first year of primary school. The behaviors measured for each child were yawning and general motor activity. It was found that: (1) The frequency of yawning appears to be 5 times higher in the first year of primary school than in the last year of kindergarten; (2) Throughout the school-day the percentage of yawning children is higher in the first year of primary school, with the exception of the 1400-1430 period; (3) In the first year of primary school, the percentage of yawning children and the frequency of yawning peak between 900 and 930 and 1430 and 1500; (4) In this school institution the percentage of children who get up from their chair and spontaneously move above increases from the beginning to the end of each school-day. Three cardio-vascular variables were investigated in 17 children of the sample population: heart rate, systolic and diastolic blood pressure. We found that: (1) The lowest values for heart rate in the first year of primary school are in agreement with the classical data of child development, as the children are 5-6 months older than in the last year of kindergarten. However, this is not the case at 1400 when the heart rate peaks at a higher level in the first year of primary school; (2) If the evolution in time of the blood pressure agrees in both institutions with the classical data of human chronobiology, i.e. the maximum values at 1400, the differences in mean level at all times during the school day between both institutions do not agree with what is commonly accepted, i.e. an increase in blood pressure with age; (3) The amplitude of the variations of the heart rate and blood pressure from one 30-min period to another throughout the school day is significantly higher in primary school. The comparison of the data obtained in both school institutions suggests that the observed differences are related to sharp modifications in school rhythms and constraints when the children go from the last year of kindergarten to the first year of primary school.

A number of concerns have been expressed about the mathematics performance of all students in our schools (see, e.g., McKnight et at. [1987]), but the performance of certain groups is particularly trouble-some. For example, on standardized tests of mathematics achievement, Hispanic students and black students consistently score below their white counterparts during the primary and middle school years. In addition, although female students perform at least as well as male students during the primary school years, some evidence suggests that gender differences in favor of boys begin to appear during the middle school years, particularly on problem-solving and applications task. Are female students black, and Hispanics naturally less able in mathematics? Or do families, schools, and the create of society offer experiences that create these differences? Individual differences in mathematics performance are normal, inevitable. and obviously related to natural ability; but no reason exists to believe that female students, blacks, and Hispanics, as groups, are by nature less able in mathematics. The problem is one of equity.

It is known that students with Specific Learning Disability (SLD) are noticed because of the difficulties they experience in academic lessons, especially in primary school years. Especially the difficulties they experience in reading, spelling mistakes, problems in arithmetic skills, attention problems, inability in taking responsibility and communication skills attract attention. The scale, which was developed in Turkey in order to identify students suspected of having SLD during the primary school years and between the ages of 8-11, by their teachers, is a five-points Likert type, 7-factors and 39-items measurement tool. The study was carried out with teachers working with students with Special Learning Disability in Ministry of Education and Special Education and Rehabilitation Centers in the 2019-2020 academic year. A total of 401 classroom teachers and special education teachers from Adana, Ankara, Antalya, Bursa, Çorum, Erzurum, Gaziantep, Isparta, İzmir, İstanbul, Kayseri, Konya, Sivas and Trabzon provinces participated in the study. In data analysis, Exploratory Factor Analysis and Confirmatory Factor Analysis were performed and a seven-factors structure was found. It was determined that seven-factors explained 73,224% of the total variance. The factors were as follows: writing process, communication skills, literacy skill, taking responsibility, attention skills, arithmetic skills and skill of recognition the numbers. The Cronbach Alpha coefficient of the scale was 0.963 and the RMSEA value was 0,063.

Neurodisability describes a broad set of conditions affecting the brain and nervous system which result in functional limitations. Children with neurodisability have more hospital admissions than their peers without neurodisability and higher rates of school absence. However, longitudinal evidence comparing rates of hospital admission and school absence in children with neurodisability to peers without neurodisability throughout school is limited, as is understanding about whether differences are greatest for planned care (e.g., scheduled appointments) or unplanned care. This study will describe rates of planned and unplanned hospital admissions and school absence due to illness and medical reasons throughout primary school (Reception to Year 6, ages 4 to 11 in England) for children with neurodisability and all other children, using linked individual-level health and education data. We will use the ECHILD (Education and Child Insights from Linked Data) database, which links educational and health records across England. We will define a primary school cohort of children who were born in National Health Service-funded hospitals in England between 1 st September 2003 and 31 st August 2008, and who were enrolled in Reception (age 4/5) at state-funded schools. We will use hospital admissions records to identify children who have recorded indicators of neurodisability from birth up to the end of primary school (Year 6, age 10/11). We will describe rates of planned and unplanned hospital admissions and health-related school absence for three groups of children: those with a neurodisability indicator first recorded before beginning primary school, those with neurodisability first recorded during primary school, and those without a record of neurodisability before end of primary school. We will further explore whether differences between these group vary across primary school years and by socioeconomic and demographic characteristics.

Aim:Adults are typically highly fluent with numerical processing and arithmetical skills. However, these abilities follow a protracted developmental trajectory, which is associated with differential changes in underpinning neural networks. However, approximately three to six per cent of children suffer difficulties with core numerical abilities and meet criteria for developmental dyscalculia (DD) (von Aster &amp; Shalev, 2007). Recent advances in developmental cognitive neuroscience have required the need to integrate data from a variety of fields. The aim of the current article is to use Interactive Specialisation Theory (IST) as a framework to examine the typical development of number processing, before considering whether IST can be applied to brain-behaviour developmental trajectories implicated in developmental dyscalculia.Method:The article uses the IST framework to review the brain-behaviour data related to typical numeracy development, before considering comparable data related to DD. Finally, an overview of interventions for DD, and how these correspond to IST will be provided.Findings:IST emphasises that that DD is not a case of delayed development of numerical skills, but represents a different developmental trajectory. IST has the potential to inform future investigative studies into DD, but also highlights ways that existing interventions may be maximised.Limitations:Whilst DD has comparable prevalence rates to other specific learning disorders and is associated with significant long-term sequelae, it is substantially under-funded and under-researched. As such further data is required on the developmental trajectories involved in arithmetical skills.Conclusions:IST provides a useful explanatory framework which has the potential to inform future investigative studies and ultimately facilitate the development of new interventions to attenuate the negative sequelae associated with developmental dyscalculia. However, further research is required before IST can inform the development of evidence-based interventions for DD.

Developmental dyscalculia (DD) is a specific learning disorder that affects the acquisition of arithmetic skills and number processing in children. A high comorbidity between DD and other neurodevelopmental disorders (e.g., dyslexia, attention-deficit/hyperactivity disorder [ADHD]) as well as substantial heterogeneity in cognitive profiles have been reported. Current studies indicate that DD is persistent, has a genetic component, and is related to functional and structural alterations of brain areas involved in magnitude representation. Recent neuronal and behavioral evidence is presented, showing that DD entails (a) impairments in two preverbal core systems of number, an approximate system for estimating larger magnitudes and an exact system for representing small magnitudes, (b) deficits in symbolic number processing, (c) aberrant and nonadaptive neuronal activation in basic magnitude processing and calculation, (d) dysfunctional arithmetic fact retrieval and persistent use of counting strategies in calculation, and (e) deficits in visuospatial working memory and the central executive. Finally, open research questions, including the role of domain-general cognitive resources in DD, causes and developmental consequences of comorbidity, as well as design and evaluation of interventions for DD, are briefly discussed.

This chapter presents a synthesis of the Australasian early childhood mathematics education research which has been conducted during the review period 2012–2015. “Early childhood education” is taken to be the education of, and for, children aged between birth and 8 years old. The research canvassed in this chapter encompasses a range of early childhood contexts, including home, school, and early childhood education services. Similarly, the research presented in this chapter has been undertaken with a range of stakeholders in early childhood mathematics education, including early childhood and school educators, families, and the children themselves. Consistent with previous reviews, this chapter is structured according to four key themes which have emerged in canvassing the current research: curriculum in early childhood mathematics education; assessment in early childhood mathematics education; content of early childhood mathematics education; and contexts for early childhood mathematics education. This synthesis of research is then used to provide recommendations for future research in this field.

The prevalence of developmental dyscalculia (DC) in the school population ranges from 3-6 %, a frequency similar to that of developmental dyslexia and ADHD. These studies fulfilled the criteria for an adequate prevalence study, i.e., were population based, using standardized measures to evaluate arithmetic function. Although the variation in prevalence is within a narrow range, the differences are probably due to which definition of dyscalculia was used, the age the diagnosis was made and the instrument chosen to test for DC. The relative predominance of girls with DC may reflect a greater vulnerability to environmental influences alone or in addition to a biological predisposition. DC is not only encountered as a specific learning disability but also in diverse neurological disorders, examples of which include ADHD, developmental language disorder, epilepsy, treated phenylketonuria and Fragile X syndrome. Although the long-term prognosis of DC is as yet unknown, current data indicate that DC is a stable learning disability persisting, at least for the short term, in about half of affected children. The long-term consequences of DC and its impact on education, employment and psychological well-being have yet to be determined.

There is a growing consensus that the neuropsychological underpinnings of developmental dyscalculia (DD) are a genetically determined disorder of 'number sense', a term denoting the ability to represent and manipulate numerical magnitude nonverbally on an internal number line. However, this spatially-oriented number line develops during elementary school and requires additional cognitive components including working memory and number symbolization (language). Thus, there may be children with familial-genetic DD with deficits limited to number sense and others with DD and comorbidities such as language delay, dyslexia, or attention-deficit-hyperactivity disorder. This duality is supported by epidemiological data indicating that two-thirds of children with DD have comorbid conditions while one-third have pure DD. Clinically, they differ according to their profile of arithmetic difficulties. fMRI studies indicate that parietal areas (important for number functions), and frontal regions (dominant for executive working memory and attention functions), are under-activated in children with DD. A four-step developmental model that allows prediction of different pathways for DD is presented. The core-system representation of numerical magnitude (cardinality; step 1) provides the meaning of 'number', a precondition to acquiring linguistic (step 2), and Arabic (step 3) number symbols, while a growing working memory enables neuroplastic development of an expanding mental number line during school years (step 4). Therapeutic and educational interventions can be drawn from this model.
