This is an account of a teacher education program's attempt to connect with a neighboring community in order to better prepare faculty to teach about the urban context in which their preservice teacher education students practice. Taking a feminist perspective, the two authors discuss their goals—the processes of using a community organization to lead the discussion and obstacles inherent to university settings. Knowledge about urban communities is an area that is often neglected in teacher preparation and one that needs to be more fully considered.  相似文献

Modern liberal rationales continue to inform a majority of teaching and learning in English art classrooms. In a postmodern Western society increasingly informed by neoliberal globalisation this approach begins to look either like an anachronism or an act of outmoded pedagogic resistance. What is certain is that the modern liberal tradition is increasingly irrelevant to a young generation of learners, but while alternative paradigms have subsequently been suggested none have come to replace the stubbornly established rationales of modernism and liberalism. This article suggests novel futures for the justification and relevance of art education that move beyond those currently prevalent. Preferable futures are suggested that synthesise postmodern practice with liberal ideals in a paradox requiring creative consideration. While the difficulties of drawing upon such contradictory rationales are noted, a case is made that if such a purpose might be accepted and imbedded in art educational futures, then there may result a more relevant and sustainable future for art education in England.  相似文献

Differential linear drift of item location parameters over a 10 -year period is demonstrated in data from the College Board Physics Achievement Test. The relative direction of drift is associated with the content of the items and reflects changing emphasis in the physics curricula of American secondary schools. No evidence of drift of discriminating power parameters was found. Statistical procedures for detecting, estimating, and accounting for item parameter drift in item pools for long-term testing programs are proposed  相似文献

This paper argues that Knowledge Management Technology (KMT) is socially constructed in use based on the affordances and constraints of the technology artefact. Since many Knowledge Management (KM) systems are introduced with vague purposes (such as to improve knowledge sharing) it is therefore their affordances and constraints which strongly shape the socially constructed ‘KMT-in-practice’. The paper argues that knowledge is also socially constructed and that knowledge creation requires an element of surprise and challenge to routine. Using a case study of the British Council's KM programme between 1998 and 2003, the paper explores the social construction of a KMT as it is developed and used; describing how various features afforded by the technology influence its adoption and institutionalisation. The paper concludes by arguing that KMTs-in-practice, which are successful in supporting knowledge creation, must paradoxically remain in a state of neither stabilisation and acceptance, nor abandonment and disuse. Practical implications of how this might be achieved are provided.  相似文献

Abstract

To evaluate the effectiveness of recovery strategies on physical performance during a 3-day tournament style basketball competition, 29 male players (mean age 19.1 years, s = 2.1; height 1.84 m, s = 0.34; body mass 88.5 kg, s = 14.7) were assigned to one of three treatment groups: carbohydrate + stretching (7.7 g · kg ?1 · day ?1, s = 1.7; ‘n = 9), cold water immersion (11°C, 5 × 1; n = 10) or full leg compression garments (18 mmHg, ~18 h; n = 10). Effects of the recovery strategies on pre–post tournament performance tests were expressed as the mean change (% ± standard deviation of the change score). Changes and differences were standardized for accumulated game time, assessed against the smallest worthwhile change for each test, and reported qualitatively. Accumulated fatigue was evident over the tournament with small to moderate impairments in performance tests. Sprint and agility performance decreased by 0.7% (s = 1.3) and 2.0% (s = 1.9) respectively. Vertical jump decreased substantially after the first day for all treatments, and remained suppressed post-tournament. Cold water immersion was substantially better in maintaining 20-m acceleration with only a 0.5% (s = 1.4) reduction in 20-m time after 3 days compared with a 3.2% (s = 1.6) reduction for compression. Cold water immersion (?1.4%, s = 1.7) and compression (?1.5%, s = 1.7) showed similar substantial benefits in maintaining line-drill performance over the tournament, whereas carbohydrate + stretching elicited a 0.4% (s = 1.8) reduction. Sit-and-reach flexibility decreased for all groups, although cold water immersion resulted in the smallest reduction in flexibility. Basketball tournament play elicited small to moderate impairments in physical test performance. In conclusion, cold water immersion appears to promote better restoration of physical performance measures than carbohydrate + stretching routines and compression garments.  相似文献

We take Mattias Lundin’s Inviting queer ideas into the science classroom: studying sexual education from a queer perspective as a point of departure to explore some enduring issues related to the use of queer theories to interrogate science education and its practices. We consider the uneasy, polygamous relationship between gay and lesbian studies and queer theories; the border surveillance that characterizes so much of science [education]; the alluring call of binaries and binary thinking; the ‘all’ within the catchcry ‘science for all’; and the need to better engage the fullness of science and the curriculum, in addition to noting silences around diverse sexes, sexualities, and desires. We catalogue some of the challenges that persist in this work, and offer thoughts about how to work with and against them to enact a more just and compelling science education.  相似文献

ABSTRACT

Ecologically minded leaders and early childhood teacher educators offer a culturally significant shiny fish project in their community as a way to launch an environmental-material reuse project. Questioning if environmental collapse is imminent, their project investigation of developing a locally relevant Remida Reggio-inspired center serves as hope for reconceptualizing early childhood practices, offering innovations, and fostering intelligent moderation of earthly resources. Finding widening circles of influence and engaging participants are key to nurturing hope, and these educators draw implications to manifest a large and impactful vision and call to action.  相似文献
