We provided Surface Pro 3 devices to all staff at the start of 2015, and have been providing professional development on the educational uses and advantages provided by the new paradigm/device.
Teaching handwriting much more effectively in the younger year levels is just one of these advantages. However, we could make videos highlighting many more areas, all the way to Senior Mathematics.
As always, improved teaching and learning outcomes drove our decision to move to this device and the digital ink/Miracast paradigm. This contrasts with what happens in education at times...find a new technology and then go searching for some reason (and at times almost any reason) to shoehorn it into the classroom.
The full article that goes with the video is available from this link.
A book with research into post keyboard technology and how the brain works is available from this link.
Some more detail of the advantages of teaching handwriting this way are available from this page on this web site.
