The Kinect sensor, meanwhile, is being used in studies to help children learn to more accurately map numbers onto physical space – a simple skill but one that is fundamental to our understanding of mathematics. Most people know, for instance, to place the number 50 exactly midway along a line marked “0” at one end and “100” at the other. Researchers at Eberhard Karls University in Tuebingen, Germany, found that seven-year-olds can place numbers along such a line more accurately if they physically walk the line on the floor – with their motion captured and analysed by the Kinect sensor – than if they use a mouse to interact with a computer screen representation of the line

Kori Krannebitter on 01 Jul 14I ask them too because I teach alg, these problems become more complicated as the year moves on and they need to write their steps down because there are multiple steps. The ones that have been doing it in their heads for years suddenly cant seem to do that anymore and find themselves in a tricky situation because they don't know how to show their work.
