本文考察了英国教育技术互用性标准中心(CETIS)通过支持国家项目(即英国联合信息系统委员会(JISC)和高等教育委员会的英国开放教育资源试点项目,详见http://www.jisc.ae.uk/oer),以促进发布开放教育资源方面的经验,并探索了如何让我们的支持模式对其他相关项目有所启发,并能改编用于鼓励开放课件运动的可持续性技术支持网络。作为一个涵盖英国众多大学的国家层面的创新举措,众多开放教育资源提供者参与了英国开放教育资源(UKOER),这包括个别教育者、学科联合体和机构。考虑到这种多样性,从一开始我们就意识到没有任何一种技术解决方案能适合所有的项目。因此,也没有委托专门的工具、描述性标准、交流或分发机制(除要求所有制作的资源应该放在国家学习资源库中外,详见http://jorum.ae.uk)。为了支持这一项目,我们引导采取不同的方法和形成不同的社群,也许在支持发布开放教育资源方面,任何类似的跨机构创新都将会面临相似的问题。我们的项目支持方法已从具体的细节问题发展到提供基本的支持原则,从而预测其他问题,并推动最佳实践。我们的做法是:通过会议上的技术汇报和讨论机会,以及在博客上发帖,激发讨论;通过技术评论讨论,并记录针对这些公布在网上的讨论的总结性内容,从而调查个别项目的技术选择;针对通过以上方式所发现的问题,以及项目博客上凸显的问题,做出相应的反馈。考虑到如何使这一方法在更广泛的范围内应用,我们也反思了这种公开的工作模式所面临的挑战、这一方法的开支、适应性,以及我们所认为的其在支持开放教育资源管理和传播方面所扮演的角色。  相似文献

Selective attention in processing of visual information by pigeons, trained on alternating sessions with two colors (red and green) and two forms (a diamond and an X shape) differentially associated with a left—right key choice task, was examined. A color and a form were presented together on probe trials during sessions in which, on other trials, only one of the dimensions, color or form, was shown. The dimension in effect on the surrounding trials had no influence on choice when the information provided by the two dimensions on probe trials was in conflict—color correct for one choice and form for the other. When both color and form redundantly cued the correct choice, there was no increase in accuracy in comparison with that associated with one dimension. Following separate training on the color and form discriminations, pigeons appeared to base their choices on color on some trials, on form on other trials, but not on both simultaneously. These findings are discussed in terms of an exemplar model of information processing.  相似文献

In 2001, the (then) Scottish Executive embarked on a process of reform of the SEN framework in Scotland. This paper analyses negotiations between different social actors, principally local authority staff and parents, in the formation of the legislation and its subsequent enactment. Data are drawn from an analysis of responses to consultations, official statistics and parent and local authority staff perceptions of the reforms as revealed in questionnaire surveys. It is argued that policy frameworks based on professionalism and bureaucracy have tended to dominate in Scotland, with a rights framework emerging much more recently. The legislation attempts to strike a balance between the different actors, although, in implementing the legislation, local authorities have sought to neutralise aspects which they felt tipped the balance of power too far in favour of parents. Parents have responded by campaigning as citizen‐consumers, and appear to be having a growing influence on Government.  相似文献

This study investigated factors related to the quality of early‐childhood practitioners’ interactions with infants in play and routine contexts. Participants were 24 practitioners working with 9–20‐month‐old infants in long day‐care infant programmes. Video‐recordings of their interactions with a nominated infant during play and in routine contexts were rated for levels of sensitivity and stimulation. Practitioners were asked to interpret extracts of this video footage and these interpretations were rated according to the complexity of the interpretive narrative. Results indicated relationships between practitioner qualification, their levels of interpretive complexity and the quality of their interactions. The quality of play interactions was significantly higher than that of routine interaction. The implications of these findings in relation to the provision of high‐quality infant day‐care programmes are discussed.  相似文献

We address the question of the quality of movies produced between 1950 and 1970. A first outcome of our analysis is that the quality assessments made during the Cannes Festival, and to a lesser degree, by the U.S. Academy are short-lasting. In contrast to this, consumers seem consistent over time. There is, however, one issue on which experts agree as well as consumers: American movies dominate both in terms of commercial success and in terms of quality. There is less agreement, and sometimes there is even dissent concerning other dimensions. This does not come as a surprise and merely indicates that there is hardly a common yardstick along which the quality of a movie can be measured. Therefore, decomposing a work of art into quantifiable characteristics – even in a subjective but possibly unanimous way – would make it possible to explain the divergences between audiences and changes of appreciation over time.  相似文献

Attendant to the changing profile of the labor pool are shifts in norms and expectations that complicate worker recruitment, hiring, and retention. As labor pool, economic, and organizational characteristics change, two issues emerge: first, the growing need to efficiently coordinate available workers with the work that needs to be done, and second, strategies for organizations to use need to be developed. Leontiefs Input/Output Theory has been used to illustrate issues related to coordination of labor, and two pre-employment tests have been studied to determine the effectiveness of pre-employment testing strategies. Pre-employment test scores obtained in an expanding contract electronics manufacturing firm have been analyzed to determine the relationships that may exist between test scores and employee success. Success has been defined as performance and retention. Multiple regression and discriminant analyses revealed several statistically significant results, including a relationship between Working Safety-test scores and performance, and Job Candidate Profile scores and retention. While interesting in and of themselves, the results further suggest that variables exist, other than those studied, that arc important to the selection of successful employees.  相似文献

Teacher preparation in science and mathematics will be best served, says the author of this roundup, by improvements both in the pedagogy and content of the undergraduate science and mathematics courses required of future teachers and in the reform of required science and mathematics methods courses. In a review of the history and politics of teacher education, the author underscores the twin goals of achieving program coherence and higher standards. She compares the place of mathematics education in mathematics departments with that of science education in science departments and recommends the replacement of bare bones methods courses with those combining pedagogy and content. Included is a selective bibliography.  相似文献

Organizational performance is highly influenced by how employees envision the future. To date, many scholars have emphasized the importance of an overarching future vision that unites all stakeholders, while acknowledging the presence of divergent perspectives among members. This variety in perspectives may be further complicated in organizations undergoing great stress and where the leadership has not defined and promoted a future vision to guide the content of the images of its members. Little study has explored the various types of future organizational images that exist or the nature of those images. We explore these concerns via a case study of an airline in the midst of a dramatic fight for survival. The findings both confirm the existence of multiple views for the company's future and delineate their general characteristics through a typology of imagery. We conclude with a language to use to differentiate those images for future research and offer practical implications for managing multiple future organizational images to mobilize energy and enhance performance in a more unified direction.  相似文献
