The main cause of Dyscalculia

Dyscalculia: News from the web:

There is still research necessary to find out exactly where Dyscalculia finds it’s origin:

Two hypotheses attempt to explain the main cause of dyscalculia. The first hypothesis suggests that a problem with the core mechanisms of perceiving (non-symbolic) quantities is the cause of dyscalculia (core deficit hypothesis), while the alternative hypothesis suggests that dyscalculics have problems only with the processing of numerical symbols (access deficit hypothesis). In the present study, the symbolic and non-symbolic numerosity processing of typically developing children and children with dyscalculia were examined with functional magnetic resonance imaging (fMRI). Control (n=15, mean age: 11.26) and dyscalculia (n=12, mean age: 11.25) groups were determined using a wide-scale screening process.

Research on Dyscalculia Subtypes

Dyscalculia: News from the web:

The new research found two robust subtypes: A slightly impaired subtype and a strongly impaired subtype. Subtypes differed most strongly regarding mathematical abilities, but the analyses suggest that differences in attention could also be a key factor. Therefore, comorbid attention difficulties seem to be a relevant factor that needs to be considered when establishing subtypes. Substantial intelligence differences between dyscalculia subtypes could not be found. Differences in working memory and reading fluency were negligible. Overall, the results seemed to be robust regardless of the diagnostic test used for assessing dyscalculia. When planning interventions for children with Dyscalculia, the existence of a subtype with substantial attention problems should be kept in mind.

Dyscalculia can hurt your career and salary opportunities

Dyscalculia: News from the web:

Not one, not two, or three studies show a direct relationship between the ability to understand and master mathematical concepts and future employment and socioeconomic success. This concept is not entirely new. Education by area has always been related to the socioeconomic factor of families. However, for the psychology professors Stuart J. Ritchie and Timothy C. Bates of the University of Edinburgh, they are mathematics the ones that take the lead in this relationship.

Spatial ability used to detect Dyscalculia

Dyscalculia: News from the web:

A thesis from 1996 had as purpose:

The purpose of this study was to examine how spatial
abilities as measured on the Kaufman Assessment Battery for
Children (K-ABC) could be used to predict dyscalculia.

Spatial abilities were found to be most closely approximated on the
Spatial Memory subtest in the ability battery. This subtest
was examined in relationship to the Arithmetic subtest on the
achievement battery, and a high correlation was demonstrated.

This is interesting because there was critisism about the traditional way of assessing Dyscalculia by comparing ability (IQ) with achievement and this was a great measure to serve as an alternative.

Dyscalculia: News from the web:

We had to share this research paper about interventions in teaching math to students with learning disabilities. The short is that the interventions were successful, for a longer and more in-depth see below, for the whole paper, click the read all about it link

The purpose of this study was to examine the effects of utilizing explicit instruction, point-of-view video modeling, and augmented reality technology to teach mathematics to students with disabilities. A multiple probe single-case research design was used. Three students with learning disabilities who were receiving special education services in mathematics participated in the study. The results were analyzed using visual analysis of trend, level, and variability. Tau-U was calculated to be 0.98 on the participants’ overall results from baseline to intervention. The results demonstrated a functional relation between the intervention and the students’ performance on three rational number mathematics skills. Participants’ maintenance and generalization of the rational number skills were measured with variable findings. The intervention was determined to be socially valid by the participants and teachers.

Here is where we find dyscalculia

Dyscalculia: News from the web:

Wonderful study that shows real differences between the brains of typical developing children and those with developmental dyscalculia.

we did find significant differences in regions-of-interest tracts which had previously been related to math ability in children. The major findings of our study were reduced white matter coherence and shorter tract lengths of the left superior longitudinal/arcuate fasciculus and left anterior thalamic radiation in the DD group. Furthermore, lower white matter coherence and shorter pathways corresponded with the lower math performance as a result of the correlation analyses. These results from regional analyses indicate that learning, memory and language-related pathways in the left hemisphere might underlie DD.

Telling time and dyscalculia

Dyscalculia: News from the web:

Considering that difficulties in reading clocks in early classes can be an early indicator of
dyscalculia, classroom teachers may need to pay close attention to the difficulties experienced by six and seven-year-old children (Burny et al., 2012). In addition, considering the procedural, semantic,
and spatial difficulties experienced by dyscalculic children, certain adaptations can be made to make it
easier for them to learn to read clocks.

It’s been known that dyslexia could affect the reading of non-language symbols like dyscalculia is the difficulty reading and understanding mathematical symbols. Although recent research supports the fact dyslexia and dyscalculia as separate conditions with unique causes they definitely are similar conditions. If the brain can process words and mathematical symbols differently, then it leaves the question of why not musical symbols too?

Spatial reasoning in early childhood

Dyscalculia: News from the web:

See the interesting article about how important the spatial reasoning along with mathematical modeling is in early childhood.

Curriculum should include ways to promote spatial reasoning through mathematical modeling to develop students’ conceptual understandings .
Mathematical tasks should include both traditional and nontraditional equations
The use of mathematical modeling should connect through a progression
of enactive models, iconic models, and formal, symbolic models. Iconic models are
one way to introduce spatial reasoning tasks and can be integrated throughout the
instructional year to increase students’ flexibility with the structure of equations
and mathematical competency.

The trouble with math

Dyscalculia: News from the web:

We are looking at a report by Ann Dowker from the University of Oxford and she makes great observations about the What Works for Children with Mathematical Difficulties?

Arithmetic is not a single entity, but is made up of many components. These include knowledge of arithmetical facts; ability to carry out arithmetical procedures; understanding and using arithmetical principles such as commutativity and associativity; estimation; knowledge of mathematical knowledge; applying arithmetic to the solution of word problems and practical problems; etc. Experimental and educational findings with typically developing children, adults with brain damage, and children with mathematical difficulties have shown that it is possible for individuals to show marked discrepancies between almost any two possible components of arithmetic.

Interventions can take place successfully at any time. However, it is desirable that interventions should take place at an early stage, partly because mathematical difficulties can affect performance in other aspects of the curriculum, and partly to prevent the development of negative attitudes and mathematics anxiety. Crucially when planning interventions, it is important to take account of the overwhelming evidence that arithmetical ability is not unitary. It is made up of many components, ranging from knowledge of the counting sequence to estimation to solving word problems. Weaknesses in any one of them can occur relatively independently of weaknesses in the others. Thus, interventions that focus on the particular components with which an individual child has difficulty are likely to be most effective.

Early Childhood Development and Lifelong Health Are Deeply Intertwined

Dyscalculia: News from the web:

The environments we create and the experiences we provide for young children and their families not only affect the developing brain but also many other physiological systems. Biological systems like the brain and the autonomic nervous system, immune system, heart and gut interact with each other and with the environment and environmental stress negatively influences all of them. Remediation may be possible at any age but outcomes are better and easier to achieve when interventions are provided earlier and more cost effective than trying to fix them later.

Research about numerosity

Dyscalculia: News from the web:

We know that people who can easily work with both actual quantities like objects or dots and with written arabic numerals and can also easily translate between them so between the non symbolic and symbolic information, have good math skills. Reason to look into the question how the brain codes numbers like 2, 4, 6, 8 if brain sources are used for both symbolic and nonsymbolic information or that they is located in separate spots. Researchers from Western University in Canada and VanderBilt, Nashville did an fMRI study with 139 healthy adults. They used a 7 Tesla machine, which is very powerful so a great signal noise quality. They found that for specific numbers, like 4 and 6, the same neural resource was used to code for quantities of dots and written arabic numerals and also that both the left and right parietal lobes were active, also the dorsolateral prefrontal cortex and that the process is specific to individual numbers in multiple formats. Not everything can be unraveled yet and how this relates to math performance and that there are individual differences in working with symbolic and non-symbolic numbers depending on their math skills

Dyscalculia: What We Must Know about Students’ Learning Disability in Mathematics?

Dyscalculia: News from the web:

Dyscalculia is one of the less well-known learning problems in mathematics due to lack of exposure and study. Children with dyscalculia usually face arithmetic and symbolic number comparison issues, with about 3-6 percent of individuals affected. The lack of wide-ranging study and inconsistency in the condition’s characterizations through studies have impeded progress in identifying the root causes of dyscalculia and how best to handle it. This problem can be more serious because it can prolong up to adulthood. Therefore, this paper will discuss the general aspects related to dyscalculia problems and their effects on children in their lives. This paper also explains the signs and symptoms that are needed to understand children who may have dyscalculia. Finally, this paper discusses what treatments or methods can be used significantly to help children improve their mastery and mathematical skills,

No Association Between the Home Math Environment and Numerical and Patterning Skills….in Belgium

Dyscalculia: News from the web:

The results of this large study show no significant impact of the home math environment on the children’s numerical and patterning skills. However the authors remark the following:

One explanation for these findings might relate to the characteristics of the general preschool system in the country of the present study (Belgium). Future studies should consider the effect of the preschool learning environment because it might explain differences between studies and countries with regard to the home math environment and its association with mathematical skills.

Retrieval or counting issues?

Dyscalculia: News from the web:

Interesting new study will be started, here is their brief:

Retrieval might not be the optimum strategy in mental arithmetic. In fact, expert adults would rather solve simple problems such as 3 + 2 by automated and unconscious procedures. Therefore, we hypothesize that children with dyscalculia might not present deficit in retrieval but, instead, in counting procedure automatization. The aim of the current project is to test this challenging position.
