Abstract

This study addressed a need to more effectively assess progress in knowledge development for complex practice domains. The result of identifying and implementing such assessment methodologies may be useful in guiding the development of instructional interventions and support mechanisms to help novices progress more efficiently and effectively toward expertise. The first challenge was to determine whether a proposed annotated concept mapping methodology could be used to identify patterns among experts in their problem conceptualizations of ill-structured problems. The second was to identify if there were differences between experts and novice problem conceptualizations. Highly experienced physicians (experts) and less experienced medical students (novices) were engaged in creating annotated problem representations for given medical diagnosis problems. The data generated were used to determine whether (1) patterns in medical diagnosis problem conceptualizations were identifiable for experts, (2) differences existed between expert and novice conceptualizations of the medical diagnosis problems, and (3) a strong argument for using annotated concept maps to assess learning in complex domains could be supported. Findings suggested that there were similarities in how experienced physicians thought about the representative ill-structured problems and these similarities were different than novices' conceptions. These findings support the notion that this methodology is useful in generating data that can aid in distinguishing relative levels of expertise in conceptualization of ill-structured problems in a medical diagnosis contexts. Discussions of the implications of this line of research and for the further development of this methodology are provided.
