The most remarkable aspect of Einstein's 1946 address at Lincoln University is that it has vanished from Einstein's recorded history. Its disappearance into a historical black hole symbolizes what seems to happen in the creation of a cultural icon. It is but one of many political statements by Einstein to have met such a fate, though his civil rights activism is most glaringly missing. One explanation for this historical amnesia is that those who shape our official memories felt that Einstein's \"controversial\" friends like Paul Robeson and activities like co-chairing the anti-lynching crusade might tarnish Einstein as an icon. That icon, sanctified by Time magazine when it dubbed Einstein \"Person of the Century\" at the end of 1999, is a myth, albeit a marvelous one. Yet it is not so much the motive for the omission but the consequence of it that should concern us. Americans and the millions of Einstein fans around the world are left unaware that he was an outspoken, passionate, committed antiracist.  相似文献

Uganda is recognised as an early success story in the HIV epidemic at least in part due to an open and vigorous national dialogue about HIV prevention. This study examined the national discourse about HIV, AIDS, and young people in New Vision, Uganda's leading national newspaper between 1996 and 2011, building from a previous archival analysis of New Vision reporting by Kirby (1986–1995). We examined the continuing evolution in the public discourse in Uganda, focusing on reporting about young people. An increase in reporting on HIV and AIDS occurred after 2003, as antiretroviral treatment was becoming available. While the emphasis in newspaper reporting about adults and the population at large evolved to reflect the development of new HIV treatment and prevention methods, the majority of the articles focused on young people did not change. Articles about young people continued to emphasise HIV acquisition due to early and premarital sexual activity and the need for social support services for children affected by HIV and AIDS. Articles often did not report on the complex social conditions that shape HIV-related risk among young people, or address young people who are sexually active, married, and/or HIV-infected. With HIV prevalence now increasing among young people and adults in Uganda, greater attention to HIV prevention is needed.  相似文献

This paper starts out from an account of deep changes in the formation of what has been called turbo-capitalism and attaches these to the emergence of wholesale auditing of all state institutions. It criticizes these hastily contrived procedures for irrelevance, narrowly financial criteria and a view of accountability indistinguishable from the politics of blame. It concludes by tracing the incommensurability of these methods with more traditional and canonical values in the polity now at risk under the impress of consumer totalitarianism.  相似文献

The concept of ‘cycles’ could be an integrative one for learning about environmental issues within several school subject areas. This concept is the subject of this study with the following question: what are the ideas secondary school students associate with the word ‘cycles’ before instruction? Students formulate their associations on the stimulus word ‘cycles’ in terms of the school subject areas ‘biology’ and ‘environment’ more than in terms of the subject areas geography or other sciences. In their formulations a restricted number of cycle ideas, relevant for the use of cycles as an integrative concept in environmental education, occurs. Possibilities for making use of the concept of cycles in lower and higher secondary environmental education are discussed.  相似文献

This Youth Participatory Action Research (YPAR) study represents a collaboration with six students from alternative education to inquire about the experiences of vulnerable youth – students in alternative education and youth who have dropped out of school. Utilizing the Enhanced Critical Incident Technique, youth researchers asked their peers what helped and hindered their retention and success in mainstream and alternative education. Youth researchers engaged in authentic participation and took part in the iterative phases of YPAR – critical reflection and social action. Their involvement empowered them to advocate for their peers by disseminating the results and recommendations to key stakeholders within the community. Youth researchers conducted semi-structured interviews with 18 participants. Overall, the findings show that relationships with staff and peers, flexibility, psychosocial and academic supports, and personal circumstances are vital in helping vulnerable students succeed in school. Engagement in YPAR provided insight into working with vulnerable youth in a manner that promotes agency and social change within educational institutions.  相似文献

In science education in the Netherlands new, context‐based, curricula are being developed. As in any innovation, the outcome will largely depend on the teachers who design and implement lessons. Central to the study presented here is the idea that teachers, when designing lessons, use rules‐of‐thumb: notions of what a lesson should look like if certain classroom outcomes are to be reached. Our study aimed at (1) identifying the rules‐of‐thumb biology teachers use when designing context‐based lessons for their own classroom practice, and (2) assessing how these personal rules‐of‐thumb relate to formal innovative goals and lesson characteristics. Six biology teachers with varying backgrounds designed and implemented a lesson or series of lessons for their own practice, while thinking aloud. We interviewed the teachers and observed their lessons. Our results suggest that rules‐of‐thumb, which differed substantially among the teachers, indeed to a great extent guide the decisions teachers make when designing (innovative) lessons. These rules‐of‐thumb were often strongly associated with intended lesson outcomes. Also, teachers’ personal rules‐of‐thumb were more powerful in determining the lesson design than formal innovative goals and lesson characteristics. The results of this study encourage more research into how rules‐of‐thumb reflect teachers’ practical knowledge, for which suggestions are made.  相似文献
