ABSTRACT

How might teachers think about moving to challenge prejudice against persons with handicap? Drawing on Piaget's and Bateson's constructivist theories, prejudices are examined in terms of the processes by which they are formed within the individual, the role they play in identity, and the reasons they may be resistant to change. Consideration is then given to strategies which may be useful in inviting reconsideration of cognitive items of this type. Looking at the learner's experience these include certain types of questioning strategies and counterexamples. Looking at the teacher's experience a number of techniques are recommended including, neutrality, circular questioning, and parenthesising.  相似文献

This paper documents the initial process by which a San Diego middle school, located in a low-income and predominantly Hispanic neighborhood and repeatedly failing to meet No Child Left Behind provisions, restructured into an academically rigorous, detracked charter school. The discussion of the political experience and working relationships between the charter organizers, the school district, and its superintendent illustrate the often contentious process of community mobilization and deliberation. The involvement of faculty from the University of California San Diego and community groups as contributing partners enhances our understanding of the creation of educational reforms or the transformation of passion into practice.  相似文献

This study tested Feeley and Barnett's (1997) Erosion Model (EM) of employee turnover which predicts that individuals who are more central in their communication network will be more likely to remain at their position (or less likely to turnover). Seventy employees from three different organizations were surveyed about their attitudes toward their jobs and were also asked to indicate (by checklist) which employees they spoke to regularly at work. Turnover data were obtained at 3 and 6 months time after the surveys were completed. Results generally supported the Erosion Model of employee turnover. Those employees with high Degree or number of links in the network were less likely to turnover. Employees who required fewer links to communicate to all others in the network (i.e., Closeness) were also less likely to turnover but this relationship only approached statistical significance (p = .06). Betweenness, defined as the frequency with which a person falls between pairs of other positions in a network, was also significantly related to employee turnover. It was also predicted, based on Feeley and Bamett's EM, that the relationship between network position and turnover would be mediated by an employee's level of commitment to the organization and his or her intentions to leave work. Closeness significantly predicted commitment while Betweenness and Degree were unrelated to commitment levels. Organizational commitment was negatively related to intentions to leave work and, unexpectedly, commitment levels were positively related to employee turnover. The results were discussed and the applications of this research for management practitioners were considered.  相似文献

For any athlete competing at the highest level it is vital to understand the components that lead to successful performance. World cup cross-country mountain biking is a complex sport involving large numbers of athletes (100-200) competing for positional advantage over varied off-road terrain. The start has been deemed a major part of performance outcome in such races. The purpose of the present study was to establish the relationship between start and finish position in cross-country mountain bike World Cup events over a 10 year (1997-2007) period and to make comparisons with a model manipulating start position based on predicted athletic capabilities. Data collection and comparisons included results from World Cup events from 1997 to 2007 (males and females), and modelled race data based on potential performance capabilities over the same period. Analyses involved the association of annual plus pooled start and finish position (Kendall's tau) along with banded mean, standard deviation for number of changes in position, while non-constrained linear regression enabled comparison between seasons. Actual race data showed significant positive correlations between starting position and finishing position (P < 0.01) in all cases but less than the model. A mean 57.4% (s = 5.6) of males changed < 15 positions, while 62.9% (s = 9.1) of females changed < 10 positions compared with modelled data (83.6%, s = 0.8 and 91.6%, s = 1.5 for males and females respectively). Individual season comparisons show general patterns to be identical (P > 0.05) for both males and females. In conclusion, finishing position is highly dependent on start position and strategies need to be devised for competing athletes to progress in the sport.  相似文献
