Build-A-Train

Dyscalculia: News from the web:

Great research done by H Moriah Sokolowski 1 2, Rebecca Merkley 3, Sarah Samantha Bray Kingissepp 2, Praja Vaikuntharajan 2, Daniel Ansari 2

The ‘Build-A-Train’ task was developed and used to examine whether children spontaneously use a number or physical size approach on an un-cued matching task. In the Build-A-Train task, an experimenter assembles a train using one to five blocks of a particular length and asks the child to build the same train. The child’s blocks differ in length from the experimenter’s blocks, causing the child to build a train that matches based on either the number of blocks or length of the train, as it is not possible to match on both. 

The Build-A-Train task and findings from this current study set a foundation for future longitudinal research to investigate the causal relationship between children’s acquisition of symbolic mathematical concepts and attention to number.

Life can be difficult for our kids

Dyscalculia: News from the web:

Children’s mental health and well-being are tied to their achievement in school. For elementary and middle school students, the classroom can be an overwhelming environment that may cause social pressure and performance anxiety.

As a result, mental health interventions are often needed to help address adverse effects, particularly for students of color who face the additional threat of negative stereotypes and biases about their ability to succeed academically, some experts say.

Finding the subitizing in groupitizing

Dyscalculia: News from the web:

‘Groupitizing’ refers to the observation that visually grouped arrays can be accurately enumerated much faster than can unstructured arrays. Previous research suggests that visual grouping allows participants to draw on arithmetic abilities and possibly use mental calculations to enumerate grouped arrays quickly and accurately. Here, we address how subitizing might be involved in finding the operands for mental calculations in grouped dot arrays. We investigated whether participants can use multiple subitizing processes to enumerate both the number of dots and the number of groups in a grouped array. We found that these multiple subitizing processes can take place within 150 ms and that dots and groups seem to be subitized in parallel and with equal priority. Implications for research on mechanisms of groupitizing are discussed.

Executive function and Dyscalculia

Dyscalculia: News from the web:

At the Ghent university in Belgium, they are planning a rather interesting project. They will review the relationship of executive function and dyscalculia. Here is what they say about it:

Project description

Dyslexia and dyscalculia are learning disorders with a high prevelance. They correlate strongly. A possible explanation can be found in the hypothesis of deficits in executive functioning. Therefore, this research maps out the profiles of executive functions. This is done by use of a comparative study existing of four groups: dyslexia, dyscalculia, a comorbid and a control group.

Who would have thought that the food you eat will impact your focus and memory? My mom would always tell me to drink milk before a test as it would help my memory but here is a nutritionist from Harvard University with some foods to avoid so you’ll maintain your focus and memory.
