The purpose of this paper is to present a cognitively-based and empirically-derived approach for the design of the RadTutor, a prototype computerized tutor to train radiology residents in diagnosing mammograms exhibiting breast diseases. A multitude of computerbased radiology training environments have recently been developed with the objective of supporting the acquisition of radiological expertise. In general, however, these systems have failed in several aspects including a failure to incorporate theoretical perspectives and empirical findings to the design of these systems. This paper outlines the conceptual framework for the development of the prototype which includes: (1) a discussion of the objectives and goals of the radiology residency training program, (2) a review and critique of existing computer-based radiology training environments, (3) a synthesis of an expert-novice study aimed at attaining a cognitive model of problem solving in mammogram interpretation (Azevedo, 1997), (4) a description of the results of analyses of authentic radiology resident teaching rounds, and (5) deriving instructional principles for the design of the mammography tutor.
