Below is a video showing how we have embraced Thinking in Ink with pen-enabled devices at my school in Singapore. The journey started in 2015 when the original Surface 3 device launched. We then went through a trial of devices and of Class Notebooks which led to whole-school adoption of OneNote for teaching and learning and moving to pen-enabled devices for all staff and students.
Currently we are exploring Teams as the possible final piece of the puzzle. Just waiting on the implementation of the parent view element.
