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

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.

The importance of math in the early years.

Dyscalculia: News from the web:

In the last decade, educators have focused on boosting literacy skills among low-income kids in the hope that all children will read well by third grade. But the early-grade math skills of these same low-income children have not received equal attention. Researchers say many high-poverty kindergarten classrooms don’t teach enough math and the few lessons on the subject are often too basic. While instruction may challenge kids with no previous exposure to math, it is often not engaging enough for the growing number of kindergarteners with some math skills.
