Check for understanding

Dyscalculia: News from the web:

Teaching is a two way street. You can be the best teacher ever but if your brilliant messages are not understood by your audience, you will not get the results you were aiming for.

simply asking ‘have you understood?’ This tells us almost nothing – as students rarely so no or could be wrong in saying yes. But, most importantly, there are always degrees of understanding. Instead of asking if, we should ask what student have understood. Rosenshine gives us a nice list of ways teachers can check for understanding.:

Visual math

Dyscalculia: News from the web:

New research is presented on the page from Stanford by youcubed from Jo Boaler and it all shows how visual math can be.

our brain wants to think visually about maths. Building students’ mathematical understanding doesn’t just mean strengthening one area of the brain that is involved with abstract numbers, it means strengthening connections between areas of the brain and strengthening the visual pathways.

How your eyes detect quantities

Dyscalculia: News from the web:

New research from the University of Sydney sheds light on how we perceive objects and know how many there are:

“Result shows that numerical information is intrinsically related to perception,” said Dr Elisa Castaldi from Florence University. “This could have important, practical implications. For example, this ability is compromised in dyscalculia which is a dysfunction in mathematical learning, so our experiment may be useful in early identification of this condition in very young children. It is very simple: subjects simply look at a screen without making any active response, and their pupillary response is measured remotely.”

‘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.
