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.

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?

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.

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.

Interesting conclusion from a new study:

Given that dyscalculia is a very heterogeneous deficit, studies examining dyscalculia should consider exploring deficits in WM because the whole group of children with dyscalculia seems to contain at least two subpopulations that differ in their calculation process.

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: 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,

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.

On today’s episode Mr Barton was lucky enough to speak to Julia Bahnmuller

Julia studied psychology in Germany, where she received her PhD in 2018. Julia is a trained dyscalculia therapist allowing her to both put her theoretical knowledge into practice and to feed research and teaching with questions and input resulting from the work with children, learning therapists, instructors and parents.

Amongst other things we spoke about:

• Number-words in different languages and the impact it can have on students’ early grasp of number and place value – wait until you hear about German!
• What are the implications for teachers who teach students for whom English is not their first language?
• And an area I know very little about… Dyscalculia

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.

Researchers have shown that children with Developmental Dyscalculia got better at solving multiplication problems and that brain activation changed after a two-week training using an interactive learning platform. Importantly, the different brain activation changes in children with Developmental Dyscalculia observed in our study once again confirms that we need to study this population as information about this disorder cannot simply be inferred from studies with typical developing children.

Visual perception has been found to be a critical factor for reading comprehension and arithmetic computation in separate lines of research with different measures of visual form perception. The current study of 1099 Chinese elementary school students investigated whether the same visual form perception (assessed by a geometric figure matching task) underlies both reading comprehension and arithmetic computation. The results showed that visual form perception had close relations with both reading comprehension and arithmetic computation, even after controlling for age, gender, and cognitive factors such as processing speed, attention, working memory, visuo-spatial processing, and general intelligence.

Remarkable study here, where they have figured out that children raised in greener area’s score higher on IQ.

A 3% increase in the greenness of their neighbourhood raised their IQ score by an average of 2.6 points. The effect was similar in richer and poorer neighborhoods.

Unfortunately they have not yet found out what causes this but they state: “The cause is uncertain but may be linked to lower stress levels, more play and social contact or a quieter environment.”
