This inter-device refresh is a relatively new paradigm with as many pluses and as minuses. One major aspect for teachers and students is how we understand the seamlessness of how this hardware ‘talks’ to one another and how one piece of media interacts with the software across all the others. This ‘talk’ is of great interest for me. As for all of us with a multitude of linked devices we are creating masses of ‘talk’ in the form of data points that lives in various guises. How these devices interact with one another is called interoperability and as our students get older, their understanding of this process is paramount in terms of this inter-device data transfer that carries their identities with it.
