This article explores how race-conscious education policy is interpreted in the political landscape of a “postracial” America. Based on a qualitative media analysis of the press coverage surrounding Amendment 46, an antiaffirmative action initiative, we examine language, statistics, and messages leveraged by advocates and critics of the ballot measure. We argue that despite using some of the same data sources, terms, and concepts, proponents and opponents of Amendment 46 proposed divergent policies. We analyzed this phenomenon vis-à-vis the framework of conflicting racial projects (Omi &; Winant, 1994 Omi, M. and Winant, H. 1994. Racial formation in the United States: From the 1960s to the 1990s, New York, NY: Routledge.  [Google Scholar]), moral paradigms of race (Loury, 2002 Loury, G. 2002. The anatomy of racial inequality, Cambridge, MA: Harvard University Press.  [Google Scholar]), and interpretations of equality of educational opportunity (Howe, 1997 Howe, K. 1997. Understanding equal educational opportunity: Social justice, democracy and schooling, New York, NY: Teachers College Press.  [Google Scholar]). Arguably, the public's understanding of race-conscious education policies relies in part on opportunities for researchers, journalists, and the public to deliberate about issues related to race. We conclude with some recommendations for fostering more communication and understanding based in deliberative democratic theory (Gutmann &; Thompson, 1996 Gutmann, A. and Thompson, D. 1996. Democracy and disagreement, Cambridge, MA: Belknap.  [Google Scholar], 2004).  相似文献

Abstract

Distance education planners make complex decisions that result in substantial investments and have long‐term implications. This article provides a framework to categorize planning issues into four distinct program stages and three decision areas. The framework brings to the surface and highlights numerous areas of uncertainty and potential disagreement among decision makers and provides an organizing backdrop to improve the distance education planning process.  相似文献

The "information era" has brought up new literacies, although most of them are still not part of the K–12 curriculum or the teacher education curriculum. One of these new literacies is critical media literacy. The purpose of this article is to document the urgency for including this new literacy in school and teacher education curricula given the crucial role of media as they touch every issue impacting human life in society. Critical media literacy as understood here includes three dimensions: (1) develop a critical understanding of how corporate for-profit media work, driven by their political and economic vested interests; (2) search for and support alternative, nonprofit media; and (3) characterize the role of teachers in helping students and their parents to become media-literate users and supporters of alternative media. Critical media literacy is founded on the legitimate role of media to serve the public's right to be truly informed, and thereby serve democracy. However, currently we are witnessing an unprecedented concentration of for-profit media into conglomerates, in alliance with the government and especially with the federal regulating agency—Federal Communications Commission—and other powerful institutions and corporations. Starting with this big picture, we examine and document specific cases that illustrate how these conglomerates and their allies work to keep and to expand their power, by means of filtering information, manufacturing consent, and controlling what the public watch, listen to, read, think, believe, taste, dress, look like, speak, and how they perceive themselves. The propaganda behind the banning of bilingual education in California is a clear example in the educational arena of the role of media in helping powerful people to manufacture voters' consent through fabricated stories, misleading ballot question, biased polls, etc. The second dimension of critical media literacy refers to the active involvement of every person, including school children, to support and advocate for alternative, nonprofit, public service-driven media. Given the reasons and the evidence presented, the authors consider that there is an urgency for including critical media literacy in the K–12 school curricula, and therefore in the teacher education core curriculum.  相似文献

The notion of Child Friendly Cities (CFCs) was first developed during the Second United Nations Conference on Human Settlements (HABITAT II), held in Istanbul in 1996. The concept is based on four general principles of the United Nations Convention on the rights of the child: (1) fair treatment of every child, regardless of ethnicity, gender, religion, socioeconomic background etc.; (2) top priority of the best interests of the child; (3) the child’s right to a better life and development; and (4) respect of children’s views. In a CFC, children are encouraged to take part in the decision making processes that affect their lives. Instead of starting yet another programme for children, the development of a CFC mobilises and connects existing agencies and actors. Giving examples of some cities in the Middle East and North Africa (MENA) region, this paper demonstrates that building CFCs has induced the development of mechanisms and structures which have enabled cities to address children’s issues in a systematic manner. These mechanisms and structures include: a municipal child-friendly legal framework, local development councils and NGO networks and local municipal development offices. The author argues that in building CFCs, the role of municipal authorities is indispensable in responding to the needs of children and young people within the municipalities’ mandates.  相似文献

Abstract

Road cycling ranks among the most intense endurance exercises. Previous studies and mathematical models describing road cycling have not analysed performances per se. We describe the evolution of road cycling performance over the past 116 years. We studied the top ten cyclists' mean speeds in eight famous classic races and three European Grand Tours, using a previously published multi-exponential model that highlights the different progression periods of an event during the century. In addition, we measured an indicator of difficulty for the Tour de France by calculating the climbing index (i.e. the total altitude climbed over total distance). The eleven races' mean speed increased progressively from 23.13 km · h?1 in 1892 to 41.19 ± 2.03 km · h?1 in 2008. Road cycling development, like other quantifiable disciplines, fits a piecewise progression pattern that follows three periods: before, between, and after the two World Wars. However, a fourth period begins after 1993, providing a speed progression of 6.38% from the third one. The Tour de France's climbing index also provided insight into a recent paradoxical relationship with speeds: when the climbing index increased, the winner's speed also increased. Our results show a major improvement (6.38%) in road cycling performance in the last 20 years and question the role of extra-physiological parameters in this recent progression.  相似文献

Abstract

The aim of this study was to examine the effect of playing formation on high-intensity running and technical performance during elite soccer matches. Twenty English FA Premier League games were analysed using a multiple-camera computerized tracking system (n = 153 players). Overall ball possession did not differ (P > 0.05) between 4–4–2, 4–3–3 and 4–5–1 formations (50%, s = 7 vs. 49%, s = 8 vs. 44%, s = 6). No differences were observed in high-intensity running between 4–4–2, 4–3–3 and 4–5–1 formations. Compared with 4–4–2 and 4–3–3 formations, players in a 4–5–1 formation performed less very high-intensity running when their team was in possession (312 m, s = 196 vs. 433 m, s = 261 vs. 410 m, s = 270; P < 0.05) but more when their team was not in possession (547 m, s = 217 vs. 461 m, s = 156 vs. 459 m, s = 169; P < 0.05). Attackers in a 4–3–3 performed ~30% more (P < 0.05) high-intensity running than attackers in 4–4–2 and 4–5–1 formations. However, the fraction of successful passes was highest in a 4–4–2 (P < 0.05) compared with 4–3–3 and 4–5–1 formations. The results suggest that playing formation does not influence the overall activity profiles of players, except for attackers, but impacts on very high-intensity running activity with and without ball possession and some technical elements of performance.  相似文献

In this qualitative case study, the researchers explored 3 8th grade teachers?? formative assessment practices as it occurred during their mathematics instruction at socioeconomic status (SES)-different schools in Taiwan. Instructionally embedded formative assessment we refer to as discourse-based assessment practice (DAP). In Taiwan, there is a large mathematics achievement gap among high SES and low SES and minority students in 8th grade. Addressing this issue at the level of classroom practice, we attempt to document teachers?? DAP using a parsimonious, but practical framework for analyzing classroom discourse in 23 lessons. For the purpose of this study, 3 lessons for each teacher are represented. The extended sequence (Mehan, 1979) was the primary unit of analysis, to which we applied our framework for illuminating and differentiating the teachers?? press for student understanding through questions and feedback. The analysis of the teacher??s instruction at the high SES indicated that it was more formative than the others, pressing for mathematical understanding. The 2 teachers at the low SES schools pressed for rote understanding, though there were qualitative differences between them. The findings raise more questions and implications for research and education policy. In Taiwan where there is scant research on classroom practices, DAP as an instructional improvement may be a starting point for educational improvement for all its students.  相似文献

This article describes how the reference department at a large academic health sciences library evolved to address the clinical and research information needs of the parent organization without losing its close connections to the classroom and curriculum. Closing the reference desk, moving to on-call and house call models, designing positions such as clinical research librarian and basic biomedical sciences librarian, finding alternative funding to grow the department, providing technology and training to facilitate librarians' work, and developing programming for and taking advice from library clients facilitated efforts to create a relevant presence and solidify the library's place in the university community.  相似文献

Social networks such as Facebook allow libraries to be proactive in reaching their users. While some libraries have popular Facebook pages, it remains unclear what attracts users to these pages. This study evaluates relationships between libraries' Facebook page content and popularity. An analysis of 72 academic health sciences libraries' Facebook pages showed positive correlations between number of library fans and number of tabs, photos, events, and wall posts on Facebook. Libraries posting videos had significantly more fans than libraries without them. This study contributes to an understanding of correlations between content and popularity on Facebook, with implications for library outreach.  相似文献
