Book excerpt: Activity Theory is a tool that can help make sense of the complex changes taking place in higher education because of the integration of technology. Unlike other theories, it allows for a focus that includes elements in the social, cultural, and historical setting in which the technology is used. In addition, it supports consideration of the practices of individual students and educators as well as practices at the institutional level. Activity Theory Perspectives on Technology in Higher Education presents a compelling theory that will be useful for researchers, academics, policy makers, administrators, and instructors interested in understanding and controlling the shifts that are occurring in education due to the integration of technology.
