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. 相似文献

In this analysis of promising practice, we demonstrate how social studies methods instructors can incorporate data analysis of the 2010 United States History National Assessment of Educational Progress (NAEP–USH) to facilitate pedagogical aims, engage teacher candidates in critical discourse, and investigate the contexts of teaching and learning. The NAEP data explorer application is a valuable tool for examining social studies theory and practice in relation to student learning outcomes. Our assessment of teacher candidates' responses to the activity leads to the recommendation that NAEP data analysis and results encourage self-evaluation of instructional practices while simultaneously supporting critical interpretations of the NAEP exam. 相似文献

Studies of the impact of education on adults’ lives must go beyond the background details of students, the course and the immediate learning outcomes, and be grounded in the changing lives of learners in a changing world. Life histories provide a rich source of data to assess the significance of education but are difficult to analyse. New approaches based on life course analysis show at what stage in students’ various ‘careers’ they participate, what else is going on at the time, and how education affects areas of their lives. The paper begins with a brief review of the literature on collecting life histories and a justification for the method adopted which provides the starting point for life course analysis. A case study of a student living in an area of multiple deprivation who took an Open University community education course is presented to show how life course analysis can be carried out and the place and influence of education evaluated. 相似文献

This article analyses how a Total Quality Management process with an embedded workplace literacy programme was implemented in an industrial manufacturing plant. Designed as an insider/outsider team research project, data were collected through interviews with management personnel, education and training providers, and hourly workers. Findings reveal that the Total Quality Management process and the literacy programme were implemented under the guise of providing education and training for workers, but were driven by corporate policy to reduce labour costs. The study also examines the way in which adult education was complicit in controlling workplace knowledge. 相似文献

This paper explores constructions of the ‘new’ university student in the context of UK government policy to widen participation in higher education. New Labour discourse stresses the benefits of widening participation for both individuals and society, although increasing the levels of participation of students from groups who have not traditionally entered university has been accompanied by a discourse of ‘dumbing down’ and lowering standards. The paper draws on an ongoing longitudinal study of undergraduate students in a post–1992 inner‐city university in the UK to examine students' constructions of their experiences and identities in the context of public discourses of the ‘new’ higher education student. Many of the participants in this study would be regarded as ‘non‐traditional’ students, i.e. those students who are the focus of widening participation policy initiatives. As Reay et al. (2002) discovered, for many ‘non‐traditional’ students studying in higher education is characterized by ‘struggle’, something that also emerged as an important theme in this research. The paper examines the ways in which these new student identities both echo the New Labour dream of widening participation and yet continue to reflect and re‐construct classed and other identities and inequalities. 相似文献
