The Vicarious Learner project is investigating the fundamental role of dialogue for learning. More specifically, the project is exploring the benefits to learners of being able to observe others participating in discussion. Such opportunities are becoming fewer with the proliferation of computer‐based courses and distance learning, as well as growing student numbers. This paper presents the theoretical aspects of the work. A high‐level ‘process model’ of learning is presented and then a more detailed model of what happens in educational dialogues. This ‘logic model’ of dialogue breaks discussions into two parts: the introduction of new premises and the derivation of new premises by the application of rules of reasoning in the domain. It is argued that in ordinary conversation the first aspect dominates while in educational dialogues, many misunderstandings arise from the need for more emphasis on explicit demonstration of use of rules.

This paper attempts to bridge the psychological and anthropological views of situated learning by focusing on the concept of a learning relationship, and by exploiting this concept in our framework for the design of learning technology. We employ Wenger's (1998) concept of communities of practice to give emphasis to social identification as a central aspect of learning, which should crucially influence our thinking about the design of learning environments. We describe learning relationships in terms of form (oneto-one, one-to-many etc.), nature (explorative, formative and comparative), distance (first-, second-order), and context, and we describe a first attempt at an empirical approach to their identification and measurement.

The term 'vicarious learning' was introduced in the 1960s by Bandura, who demonstrated how learning can occur through observing the behaviour of others. Such social learning is effective without the need for the observer to experience feedback directly. More than twenty years later a series of studies on vicarious learning was undertaken in the context of technology-enhanced learning in mass higher education. These studies employed the idea in a rather narrower sense, defining it as learning through observing others in the act of learning, focusing in particular on the kind of conceptual learning that is typical in higher education and is best observed in tutorial settings. The key proposal was that multimedia recorded versions of tutorial dialogues could be chosen for their effectiveness in revealing the way concepts are grasped, questions posed and problems solved, from the perspective of real learners rather than from that imagined by teachers. These recorded dialogues could be linked to the primary subject matter and, it was hoped, would constitute a powerful resource for new students who would otherwise not have the opportunity to benefit from a teaching method which, if restricted to the original participants, simply does not scale. This paper reviews the subsequent research that has continued to explore this idea. Overall, the potential importance of vicarious learning in various kinds of subject matter has been confirmed. Research on vicarious learning continues to resonate with fundamental issues of the design of higher education in a digital world.
