With the COVID-19 pandemic rapidly escalating higher education's move online, this timely Handbook presents holistic conceptualisations of digital higher education which consider change at personal, pedagogic, and organisational levels. Key findings from digital education research and case studies of institutional practices consider the current and future roles of digital technologies in higher education. Examining the changing roles of learning and teaching in digital higher education, the Handbook critiques the current state of the field and considers the impact of digital technologies on the symbiotic relationship between research and practice, pointing to the importance of reflexive professional practice. Through conceptual frameworks and methodologies, chapters demonstrate that researching digital higher education needs to be pluralistic, longitudinal and developmental in order to be rigorous, credible and have impact. The Handbook concludes with a look to future directions of digital higher education, including the key principles of innovation, inclusivity, collaboration and engagement, and sustainability. This Handbook's diverse critical approaches to digital change will be invaluable to researchers and students of education policy and organisational innovation. Dealing extensively with how strategic and policy decisions surrounding digital higher education are made, implemented and evaluated, it will also prove useful to institutional leaders and policy makers in higher education.
