The development of a 'Standardised Learner' in researching teaching behaviours.

Standardised patients are increasingly used in medical education and the reliability and validity of their use as an assessment method are supported by published research. This paper details the application of this methodology to the educational interaction between a teacher and a learner using a standardised learner.In contrast with standardised patients, a standardised learner must use a level of medical knowledge and experience appropriate for the role assumed. Some aspects of reliability and validity have been considered and appear supportive of this methodology.The feasibility and value of this method for researching actual teacher behaviour are discussed.
