The explanatory role of spontaneously generated analogies in reasoning about physiological concepts

Analogical reasoning is increasingly recognized as an important instrument for promoting conceptual change in science learning. This study characterized students' and physicians' spontaneous use of analogies in reasoning about concepts related to the mechanical properties of cardiovascular physiology. The analogies were made in response to questions at different levels of abstraction from basic physiology to clinical problems. The results indicate that analogies generated by subjects facilitated explanations in a number of ways. These include creating coherent representations in novel situations, bridging gaps in understanding, and triggering associations which result in modified explanations. Subjects at different levels of expertise used analogies differently. The more expert subjects used analogies to facilitate articulation and communication; that is, to illustrate and expand on their explanations. Novices and advanced medical students used more between‐domain analogies to explain all categories of questions. This is less evident in physicians' responses to pathophysiological and clinical problems. The paper discusses ways in which analogies can be used productively, and identifies factors that can lead to a counter‐productive use of analogies resulting in misconceptions and erroneous explanations.     

The validity and reliability of focus groups as a research method in adult education

The article examines the theory and practice of focus groups in adult education research. Three theoretical positions are described: radical hermeneutic, moderate interpretative and pragmatic realistic position trying to bridge the gap with positivist research. This last position has been chosen as the departure point for a further analysis of the focus group elements, which relate to validity and reliability. The research examines four European research projects in the field of adult education. The most important and surprising data are presented with reference to both socio-psychological and technical problems in the use of this method. The results highlight the importance and dynamics of all the elements discussed.     

Success stories: aspirational myth in the education of adults

Understanding the influences upon curriculum formation is an ongoing challenge for adult educators. This discussion describes one approach to curriculum analysis—the aspirational myth—based on the notion that instructors and learners co‐construct an idealized identity representing the end point of learning. The aspirational myth is described with reference to an empirical case study of a training programme, and implications for teaching and research discussed.
