Society is facing a significant educational challenge in future, if predictions such as those around job automation are fully realised. However, whilst technology is transforming society at an ever increasing pace, little has changed at the heart of how we educate people, which will become increasingly important for reskilling and upskilling the population as they progress through multiple careers in their lifetime. This talk will look at the impact of technology on society and the consequent educational needs going forward. It will draw together lessons learned from recent research in mass education with research in the development of sophisticated intelligent training tools designed to provide realistic and engaging educational experiences, and discuss how these can be combined to provide engaging, immersive and just-in-time, online mass education.
