This article examines the promotion and adoption of action research as an instrument of institutional change by academic staff in a Brazilian rural university. The results of the research are presented showing the mobilisation of a group of volunteers, the implementation of their action research projects and the sustainability of the process. Particular attention is drawn to the significance of an insider change agent/facilitator as the initiator of the action research process and how his role became superfluous as the networks evolved into true communities of practice. On reflection the original composite daisy model of Melrose and Reid has been discarded in favour of a simpler buttercup‐type flower model of analysis to describe the process. 相似文献

In this study we investigate students' learning during their interaction with two exhibits at a science center. Specifically, we analyze both students' procedures when interacting with exhibits and their understanding of the scientific concepts presented therein. Bernstein's theory of pedagogic discourse (1990, 2000) provided the sociological foundation to assess the exhibit–student interaction and allowed analysis of the influence of the characteristics of students, exhibits, and interactions on students' learning. Eight students (ages 12ndash;13 years of age) with distinct sociological characteristics participated in the study. Several findings emerged from the results. First, the characteristics of the students, exhibits, and interactions appeared to influence student learning. Second, to most students, what they did interactively (procedures) seems not to have had any direct consequence on what they learned (concept understanding). Third, the data analysis suggest an important role for designers and teachers in overcoming the limitations of exhibit–student interaction. © 2006 Wiley Periodicals, Inc.

Co-operative learning for students with difficulties in learning: a description of models and guidelines for implementation 总被引:1,自引:0,他引:1
As part of a larger study regarding the inclusion of children with disabilities in mainstream classroom settings, Ellen Murphy, of the D Clin Psych programme at NUI Galway, with Ian Grey and Rita Honan, from Trinity College, Dublin, reviewed existing literature on co-operative learning in the classroom. In this article, they identify four models of co-operative learning and specify the various components characteristic of each model. They review recent studies on co-operative learning with the aim of determining effectiveness. These studies generally indicate that co-operative learning appears to be more effective when assessed on measures of social engagement rather than academic performance. Finally, Ellen Murphy, Ian Grey and Rita Honan present their account of the factors that contribute to the successful implementation of co-operative learning for students with difficulties in learning. 相似文献

This essay considers Food Will Win the War, an animated short made early in World War II by Disney Studios for the United States Department of Agriculture. Through a fantastical catalogue of hyperbolic images, the film shows how the mass production of American agriculture becomes the first wave of a new American-style consumerism of plenty that will transform the social order. The analysis blends contemporary theories of affective politics to show Food Will Win the War as a threshold text, revealing the post-war economy at its formation. Using food as a symbolic field, this film ultimately links the endless expansion of consumer desire to national identity and global colonization. 相似文献
