Causes of Developmental Dyscalculia

Dyscalculia: News from the web:

Interesting article from the Centre for Neuroscience in Education. Their view:

Overall, there is substantial evidence to suggest that there is no unique functional impairment at the heart of developmental dyscalculia, but that several cognitive functions may be implicated. Consequently, at the CNE maths group we adopt a multi-computational view of dyscalculia; rather than focusing on the search for a unitary underlying cause of dyscalculia, we aim to identity whether the condition can be related to individual variability in specified components of several cognitive functions such as memory and attentional processes.

Research to The Origin of Mathematics and Number Sense

Dyscalculia: News from the web:

It is concluded that difficulty with “number sense” results from the extended demands on executive
control in learning inverse dynamics models associated with cerebellar inner speech related to the second tier of
abstraction (numbers) of the infant’s primitive physics.

Reading, Writing and……. Arithmetic

Dyscalculia: News from the web:

New research confirms that the sequence is indeed reading, writing and then arithmetic.

results of our analysis confirmed the role of preschool phonological ability as a domain-general predictor of later achievements. Phonological ability had a positive direct and indirect effect (via reading fluency) on the subsequent reading and math performance.

the original use of Intelligence Testing

Dyscalculia: News from the web:

I just never know but:

While Alfred Binet is credited with the first intelligence test, that was far from his intent when he and his colleague developed the Binet-Simon scale in 1908. The purpose was not to predict future performance, but simply to identify students who were in need of alternative educational approaches.

If you ever wanted to know where exactly dyscalculia sits in your brain

Dyscalculia: News from the web:

It is not recent but this article gives great insight in exactly what is going on in the brains of children with developmental dyscalculia. Share this article with those people who “do not believe in dysalculia” or who “do not subscribe to that” (actual quote from a school counselor!).

The limits of RTI

As a method of organizing efforts to help students who are struggling academically, response to intervention has seen widespread adoption. But as an improved method of identifying students with learning disabilities, RTI shows far less clear benefits, researchers are finding.

Anxiety in your genes?

Dyscalculia: News from the web:

In a study, published today in Scientific Reports, researchers measured anxiety in a sample of more than 1,400 twin pairs aged 19 to 21 from the Twins Early Development Study (TEDS).

All forms of anxiety showed a substantial genetic component, with DNA explaining over a third of the differences between people.

The importance of math in medicine and your health

Dyscalculia: News from the web:

Breast Cancer Patients Need to Know the Numbers for Treatment Decisions Risk calculations, treatment evaluations, and assessing the odds of a medication’s side effects are all part of the process of deciding which treatment is best for breast and other cancers.

But not everyone is good at math, and sometimes this process can be intimidating. For these patients, decision science research can offer well-founded advice on how to evaluate the information and make knowledgeable decisions.

Research into a general magnitude system

Dyscalculia: News from the web:

New research has been done in the theory that number, space and time might be part of a generalized magnitude system and that deficits in that system could explain Developmental Dyscalculia. It is quite a good read but their main conclusion is:

Deficits in number processing and arithmetic cannot be explained with a general magnitude deficiency. Our results further indicate that multiple neuro-cognitive components might contribute to the explanation of developmental dyscalculia.

Dyscalculia and ADHD

Dyscalculia: News from the web:

Deficits in basic numerical skills, calculation, and working memory have
been found in children with developmental dyscal-
culia (DD) as well as children with attention-deficit/hyperactivity disorder (ADHD). This paper investigates cognitive profi
les of children with DD
and/or ADHD symptoms (AS) in a double dissociation design to obtain a better understanding of the comorbidity of DD and ADHD.

What teachers know about dyscalculia

Dyscalculia: News from the web:

A study about this has now been done:

Although much research on teachers’ knowledge and attitudes
towards their students with dyslexia has been accumulated, students
with dyscalculia have not gained the same attention. Teachers’
knowledge about the nature and characteristics of students with
dyscalculia seems to be limited and this has a strong impact on their
instructional decisions. In secondary education, where teachers’ pre
service educational programs are more focused on the scientific subject
instead of appropriate instructional methods, teachers’ knowledge about
dyscalculia has not yet been taken into account.

The role of language in Mathematics

Dyscalculia: News from the web:

Martin Saunders writes a good story about the role of language in children’s learning of Mathematics. His conclusion (but you really need to read the whole piece in our link for today):

In summary, it is clear that language is a requirement for mathematical cognition, if not higher cognition in general. Where language is a component of understanding it must also be a requirement for the learning process. A symbiotic relationship exists where dialogue, and in particular creating explanations, aids to build understanding but also to apply this understanding in ever more complex ways. As the ability to consider multiple conceptual areas collectively grows and with number facts readily available a proficient mathematician develops who is able to reason and problem solve with fluency.

More on Neuro diversity

Dyscalculia: News from the web:

Neurodiversity. It’s not a term that rolls off the tongue easily but it’s a concept where neurological differences are to be recognized and respected as any other human variation. These differences can include those labeled with Dyspraxia, Dyslexia, Attention Deficit Hyperactivity Disorder, Dyscalculia, Autistic Spectrum, Tourette Syndrome, and others. Now organizations such as Microsoft and EY are piloting programs to recruit individuals who have neurological conditions such as Asperger’s which comes under the Autism Spectrum Disorder (ASD), a range of conditions that affect the way a person sees the world, processes information and interacts with other people.

From the White House Science Fair

Dyscalculia: News from the web:

Devon, 14, and Trevor, 11, Langley representing a team from Terre Haute, Indiana, harnessed the power of the rainbow to help dyslexic students learn mathematics. This innovative young team developed the ROY G. BIV Math System, an app designed to improve the way children challenged with dyslexia learn new math concepts. A color-coded system keeps digits in place when children do any kind of math operation. The system uses the rainbow color order so children will recognize if they unintentionally move digits because the familiar ROY G. BIV pattern will also be out of order. By assigning a unique color to each place value, the system makes mathematical operations easier for a child with dyslexia to follow, and also offers learning benefits for children with dysgraphia or a more serious math disorder called dyscalculia. The team’s colorful innovation earned them the FIRST LEGO League Global Innovation Award.

Air pollution and dyscalculia?

Dyscalculia: News from the web:

We have only seen the abstract so we don’t have all the details but we are happy that there was a study to see if air quality and dyscalculia are connected. Well here is what the researchers conclude,

We report associations suggesting a potential link between air pollution exposure and hyperactivity/inattention scores, although these findings require replication.

So it does not sound that they found a valid correlation with dyscalculia.

The case against multi tasking

Dyscalculia: News from the web:

Smart people at the Linköping University have found out that the brain really focusses only on one thing at a time. So if you are doing one thing, chances are that the brain will reduce some other activities.

The results show that brain activity in the auditory cortex continues without any problems, as long as we are subjected to sound alone. But when the brain instead is given a visual task, such as a written exam, the response of the nerves in the auditory cortex decreases, and hearing becomes impaired.
