Looking at the conflictual constitution of educational systems by equality and excellence, this paper examines the discursive formation of two political rationalities in the contemporary German educational system that are directly opposed. While early childhood and primary education discourses are dominated by a terminology of equity, tertiary education institutions such as universities are described with a terminology of excellence that has become a reference point for political interventions and institutional reform processes.Taking up the theoretical position of hegemony-theory, governmentality studies and system theory, the paper analyzes the rules of justification these hegemonic discourses refer to by employing a discourse analysis of strategic, conceptional, and institutional texts of the German education policy discourse between 2003 and 2010. The paper puts forth the thesis that mobilizing and optimizing represent the common principles of equality and excellence as rationalities of the maximal mobilization of educational ressources. 相似文献

In countries such as the UK, schools have a responsibility to prevent all forms of bullying, including those related to sexual orientation. However, relatively little is known about how schools go about this work successfully. This study aimed to identify how three secondary schools in south London, England, were addressing homophobia. Three different kinds of schools – a co-educational, boys' and girls' school – were selected, each known to have conducted work to counter homophobic bullying. In each school, interviews were conducted with staff and pupils. Work on homophobia and homophobic bullying was said by most staff respondents to be part of a general commitment to countering bullying. Pupils stated that they were keen that homophobic bullying should be tackled – and distinguished bullying from ‘cussing’, ‘taking the mick’ and ‘mucking about’. Work carried out in schools had influenced pupils to consider homophobia and its effects – although the media as well as personal and family relationships were also important in this respect. Findings are discussed with regard to ways in which schools might better align what they do with regard to pupils' own values and understandings about how best to address homophobia and bullying. 相似文献

With children using digital media at ever younger ages, media-education becomes a pressing issue for parents. As there is hardly any research on how parents guide the online activities of toddlers and young children an internet-survey was held among 792 Dutch parents of children aged between 2 and 12 years. Factor analysis revealed that for the internet, parents partly use the same strategies they also apply for television and video games: ‘co-use’, ‘active mediation’, and ‘restrictive mediation’. In addition, they also utilise new strategies: ‘supervision’ and ‘technical safety guidance’. Mediation was mainly predicted by the child's age and online behaviour (e.g., gaming, social networking), as well as by the number of computers in the home and the parents' gender, education and computer/internet skills. Finally, parents also use more mediation when they expect that the internet has a positive effect and particularly when they believe that it has a negative impact. 相似文献

In this article, we explore how youth audiences evaluate the quality of youth-produced films. Our interest stems from a dearth of ways to measure the quality of what youth produce in artistic production processes. As a result, making art in formal learning settings devolves into either romanticized creativity or instrumental work to improve skills in core content areas. We conducted focus groups with 38 youth participants where they viewed four different films produced by the same youth media arts organization that works with young people to produce short-form, autobiographical documentaries. We found that youth focused their evaluations on identifying the films' genre and content and on assessing how well the filmmakers' creative decisions fit with identifications of genre and content. Evaluations were mediated by audiences' expectations and seemed to inform judgments of quality and creativity. We hope that our work can inform the design of formal learning spaces where young people are producing narrative art. 相似文献

The Vanderbilt Assessment of Leadership in Education (VAL-ED) provides educators with a tool for principal evaluation based on principal, teacher, and supervisor reports of principals’ learning-centered leadership. In this study, we conduct a known group analysis as part of a larger argument for the validity of the VAL-ED in US elementary and secondary schools. We asked superintendents to select the principals in their district who they believe in performance of their duties are in the top 20 % and the bottom 20 %. We ask how accurately VAL-ED scores can identify membership of the two known groups. Using a discriminant analysis, the VAL-ED places principals in the superintendent groups, on average, 70 % of the time for both elementary and secondary schools. Placement accuracy is greater for the top group than the bottom group. 相似文献

The increase in smartphone adoption has been no less than astounding. Unfortunately, the explosive growth has been accompanied by a rash of security problems. A contributing factor to the growing security problem is a lack of education, training, and awareness. In addition, “bring your own device” (BYOD) policies often leave security responsibilities to the competencies of device owners, which compromises security. Today’s students are tomorrow’s employees with responsibilities for protecting their work environment. They need to understand and practice a full-range of mobile security practices so that they can safely access the information assets of their organizations. If students are not engaging in such practices, educational institutions have a responsibility to ensure that students understand how to keep information assets secure. This paper investigates the smartphone security practices of undergraduate college students. Five hundred students in business classes at a regional public university were surveyed to determine their use of recommended smartphone security practices. The study found that many smartphone users did employ some security measures, but a high percentage of them were ignoring potential risks. This suggests a need for increased education, training, and awareness. 相似文献
