Listening to MIT's Vijay Kumar speaking is always informative. Kumar has vast experience in research in online and digital learning environments, and he conveys his knowledge in an accessible style. He was keen to argue that the future of education has two fundamental characteristics - open and digital. His previously published book Opening Up Education explains the first in plenty of detail, but the second, digital, was uppermost in his keynote presentation at ELI 2015, the Saudi Arabian premier e-learning event. He said that it is at the intersection of digital and open that learning innovation occurs, and that education will be transformed if attention is paid to them both.
