Hands Up! Why We Should Promote Visual Arithmetic

It is well known that schools tend to put mental arithmetic skills above the visual ones, as something like counting with your fingers is seen as a weakness in one’s calculation abilities. Educators and scientists have been tackling this obsolete cliché with research and scientific reports that seem to prove that visual aids are more than just helpful in the learning process.

Indeed, visual aids, such as the use of fingers, have a key role in children’s understanding of mathematics. This form of visualisation gives the abstract world of numbers a real side and establishes a connection to something tangible. This results in the creation connections from the prefrontal cortex (main memory / data centre) to the visual and motor cortex. Thus, when visual aid is used, thinking becomes outsourced to other brain areas generating a more efficient use the brain’s capacity.

However, these findings do not mean that you child will forever use their fingers to count. Over time a mental image of the fingers will become connected to the mental processes of counting, making the physical counting unnecessary. This is proven by numerous studies with primary school children that measured increased activity in the visual cortex while children were solving complex math tasks, even when they did not use their hands.

Top 5 Dyscalculia Videos

This week we have searched high and low for the five best videos on dyscalculia and here they are!

 

1. My world without numbers – Line Rothmann

At number one we have the fantastic Tedx Talk from Line Rothmann. She has dyscalculia and tells us of what is like and what quirky systems she developed to get on in a world that is largely based on numbers.

Upcoming Conference: Dyscalculia, Numeracy and Maths Anxiety

Dyscalculia conferences do not come around too frequently. For readers who can make it to the U.K., more specifically to Longborough, early bird tickets are still available for Dyscalculia, Numeracy and Maths Anxiety in Further and Higher Education.

When: 12 April 2017

This is a one-day conference focusing on dyscalculia and maths anxiety in further and higher education. The program presents recent research in the field as well as draws on developments and a number of case studies.

Dyscalculia And The Brain

Dyscalculia And The Brain

We are very pleased to feature a guest post from PD Dr. Karin Kucian, associate professor at the Centre for MR-Research of the University Children’s Hospital of Zurich. In her article for the Dyscalculia Blog, Dr. Kucian explores changes in brain function and brain anatomy and how these relate to developmental dyscalculia.

Evidence is growing that Developmental Dyscalculia (DD) is associated with various altera­tions in brain function and brain structure. Recent work in the field of DD has used brain-imaging techniques to study the brains of people performing number tasks. These techniques have allowed researchers to generate high-resolution images of participants’ brains, making it possible to observe brain activation patterns during number processing. Read more

“More Awareness & Training needs to be Provided for Teachers…to aid them in Supporting Children with Dyscalculia”

“More Awareness & Training needs to be Provided for Teachers…to aid them in Supporting Children with Dyscalculia”

Natalie Kerslake spoke with the Dyscalculia Blog on the need for more awareness of dyscalculia in the classroom.

This week the Dyscalculia Blog interviewed Natalie Kerslake, a teaching assistant who conducted her master’s degree research around dyscalculia. Natalie shared her thoughts on the importance of increasing school resources for dyscalculics and their teachers.

Please introduce yourself to the blog and tell us what motivated you to focus on dyscalculia.

My name is Natalie Kerslake B.A (Hons), MA Ed and I am a primary school teaching assistant, with a particular interest in supporting children with special educational needs and disabilities.

I became motivated to complete my MA Ed research on dyscalculia after supporting a child with this in my first teaching assistant post. I did not know anything about dyscalculia myself at the time and not much was available to support teachers and children in this area. I wanted to investigate the current situation as to supporting children with dyscalculia in one particular primary school, and see whether this was the case in another school. Read more

Numberphile: Dyscalculia Explained

Numberphile: Dyscalculia Explained

At first glance the Numberphile website seems both charming and a tad overwhelming. The site is dedicated to numbers and explanations of math problems and math research by means of short videos. The videos are linked to via illustrations which are engaging but don’t give a casual visitor many clues as to where they are navigating. It is great for exploring though: click around and see which page you land on and then watch the video to learn something new about math. Read more
