twice-exceptional

Dyscalculia: News from the web:

The concept of gifted students who also have learning disabilities (G/LD students), also referred to as “twice-exceptional” students, has become widely accepted, however only a very small number (~5%) of articles on this subject use empirical data. Much is written about this population based on very little empirical evidence and there is not yet much consensus on how to define and identify these students. The research in the link for today also summarizes a literature overview and draws conclusions.

Yes you can retrain the brain

Dyscalculia: News from the web:

Many aspects of the brain can be altered as the brain is neuroplastic. “This means that the brain can change throughout an individual’s life and with the right stimuli, it can be trained to become more efficient in spite of any brain disorders or labels that one may have been born with.”

Guidance on teaching Math

Dyscalculia: News from the web:

The Education Endowment Foundation has published guidelines for primary and secondary teachers on how to boost math skills with children. They make the following observations:

  • Pupils should master basic mental arithmetic – addition, subtraction, multiplications and division – and be able to recall their times tables quickly. Those who don’t may well have difficulty with more challenging maths later in school.

  • Pupils sometimes think “multiplication makes bigger, division makes smaller”. This is accurate with numbers greater than 1, but isn’t right when applied to numbers less than 1. So, 5 x 5 =25 but 0.5 x 0.5 = 0.25.

  • Learning how to add fractions together can often cause difficulty. For example, many think the answer to 1/8 + ½ is 2/10. Teachers can help pupils to understand that the right answer is 5/8 using diagrams which help to visualise the different values of fractions.

Computer-assisted Neurocognitive rehabilitation not that effective?

Dyscalculia: News from the web:

Intering results that will need some follow up:

The results of covariance analysis showed that cognitive rehabilitation interventions did not lead to a significant difference between the experimental and control groups in inhibitory, omission, commission and reaction time scores

Brain activity of dyslectic and dyscalculic students more similar than we thought

Dyscalculia: News from the web:

Here are the highlights of this new study:

 

  • fMRI was used to investigate the neural correlates of arithmetic in children with dyslexia, dyscalculia, comorbid dyslexia/dyscalculia and controls.
  • Univariate and multivariate analyses pointed towards substantial neural similarity between children with learning disorders
  • Despite behavioral differences, brain activity profiles of children with learning disorders in the context of arithmetic appear to be more similar than initially thought

No Evidence for Systematic White Matter Correlates of Dyslexia and Dyscalculia

Dyscalculia: News from the web:

A very interesting study has been completed. They compared people with dyslexia, dyscalculia, both and neither. They focused on the corona radiata and the arcuate fasciculus, two tracts associated with reading and mathematics in a number of previous studies. Using Bayesian hypothesis testing, they showed that the data showed no differences between groups for these particular tracts, a finding that seems to go against the current view in other studies.
This outcome, if confirmed, suggest that structural differences associated with dyslexia and dyscalculia might not be as reliable as previously thought, and this may have some impact on how we approach remediation.

How do you process magnitudes?

Dyscalculia: News from the web:

Interesting study which outcome favors the possibility of a generalized magnitude system in the occipito-parietal lobe. It might be further assumed, that with development more refined and specific neuronal functions form in order to process magnitudes with increasing difficulty (Leibovich and Henik, 2013). Secondly, despite the numerical deficits and difficulties in more complex spatial skills, adolescents with DD seem to have well developed abilities to process discrete and continuous magnitudes. Neuronal findings may reveal the use of compensatory systems, hinting to a slight delay in the development of the discrete and continuous numerical system. Further studies are needed to examine the development of the generalized magnitude system in typical and, more importantly, in atypical development.

A non math related test in the first year of school can predict Math success later

Dyscalculia: News from the web:

Great research that shows that when you have children try to order a set of animal pictures after you have read the names of the animals to them, the success of them being able to do this simple task predicts later Math capabilities.

Computer aided instruction and Dyscalculia

Dyscalculia: News from the web:

ADHD related to food allergies?

We see often that children with ADHD also have Dyscalculia and the other way around, we see children with Dyscalculia and many of them also have ADHD. Now a new study suggests:

A study examining the connection between mental health issues in children and common physical conditions found a link between allergies and behavioral disorders like ADHD and ODD.

Participation in Early Childhood Education reduces Special Education Placements

Dyscalculia: News from the web:

New research shows that on average, participation in ECE leads to statistically significant reductions in special education placement (d = 0.33 SD, 8.1 percentage points) and grade retention (d = 0.26 SD, 8.3 percentage points) and increases in high school graduation rates (d = 0.24 SD, 11.4 percentage points).

Retrieval or Counting; New study, not even open

Dyscalculia: News from the web:

Researchers are planning a project for the following reason:

Researchers in numerical cognition usually think that the greatest and most common difficulty in children suffering from dyscalculia is retrieval of arithmetic facts from long-term memory. However, we have recently shown that 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.

Very interesting but it will take a few years to complete. We will follow this.

Stop the comparing method

Dyscalculia: News from the web:

Traditional definitions of Developmental Dyscalculia state that a child must substantially underachieve on mathematical abilities tests relative to the level expected for the given age, education and intelligence. However, current
cognitive developmental neuropsychological studies suggest that not only the core numerical but also the cognitive skills of children with developmental
dyscalculia present deficits.

Dyscalculia and Art

Dyscalculia: News from the web:

Here’s a couple of quotes:

“Problems centred in the left side of the brain like Asperger’s, ADD, dyslexia, dyscalculia and motor skills can be improved through art therapy.

“There’s much neurological research done that shows we’re increasing the right side of the brain through colour and visualising and using cognitive interaction.

“Problem-solving is a creative process and art is very beneficial to reduce stress and anxiety.”

Math as creativity

Dyscalculia: News from the web:

Best quote:

There are no topics in mathematics; only artificial barriers that we have erected to help organise the curriculum. At school, we study topics in discrete chunks and come to understand them as separate islands of knowledge. Yet the most powerful and interesting mathematics arises when we cut through these barriers.

Rethinking Giftedness from YouCubed on Vimeo.

Great quote: The labelling of some students sends negative messages about potential, that are out of synch with important knowledge of neuroplasticity showing that everyone’s brains can grow and change. But few people realize that those labels are damaging for those who receive them too.

Yes, Dyscalculia is inborn, read the proof.

Dyscalculia: News from the web: (not new but still very relevant)

Karin Landerl and her team at the University of Graz, Austria, investigated the development of numerical processing in elementary school children with dyscalculia and a control group with good arithmetic skills.

Landerl and colleagues conclude a biologically driven deficit causes children with dyscalculia to have an imprecise internal representation of numbers, which explains these children’s difficulty with the number line task.
