Activity Theory is a framework, in the essence of which lies the notion that an activity can be represented as the action of a subject on an object, but this will always be mediated through the employment of an external artefact. It was originally formulated in Russia in the 1920s by Lev Vygotsky and further developed in the 1990s by Yrjö Engeström. This book presents a further extension of Activity Theory by incorporating the identity of the subject and the situated experience of the setting of the activity within its framework.
