The results are presented of a policy-focused review of career guidance services in 10 Middle East and North African countries. A range of economic, political, socio-cultural and educational factors which seem likely to have constrained the development of such services, and to have influenced the forms they have taken, are discussed. A number of drivers for change are outlined, the nature of the main current services is described, and a number of common issues are explored. Six broad themes are identified for the future development of career guidance services within the region. 相似文献

Given the prevailing spirit of teacher frustration regarding current educational policy, the authors perused frequently visited teacher blogs and discussion boards in the summer of 2009 to determine whether teachers are effectively using them to express professionally informed political dissent regarding educational policy. While many teachers are frustrated with educational policies, they are not particularly adept at voicing their dissent against such policies. Many downplay their professional knowledge, avoid overtly political postings, and feel isolated from others who share their views. 相似文献

Background The use of research evidence produced by others is seen as central to the reflective practice of school teachers. There have been many recent UK initiatives aimed at improving access to research evidence, but there are still concerns about the lack of engagement by teachers. Previous research has looked at this issue from different perspectives, including the content and relevance of educational research, the relationships between researchers and teachers, accessibility and presentation of research and the culture of the school. The research presented here seeks to make a contribution to understanding the diffusion of research in the teaching profession by examining the issues from an information literacy perspective. Purpose This paper examines the use of research information by UK school teachers, placing an emphasis on their information literacy—i.e. teachers' strategies and confidence in their abilities to find, evaluate and use research information, which is defined as the published output of a planned piece of research. Sample Survey data were collected from 312 teachers and 78 head teachers from nursery, primary and secondary schools in Scotland, England and Wales. The sample included a wide range of teaching experience, ages, subject responsibilities, school locations and sizes, although there was a bias towards teachers who were motivated to use research evidence. Interviews were conducted with 28 teachers from primary, secondary, nursery and special education schools, and a further 15 teachers took part in group exercises. Interview and group exercise samples were more varied in their levels of research involvement. Design and methods A mixed methodology was used. The questionnaire survey sought background data on more general attitudes towards research, as well as data on information access and confidence in finding and using general and research information. This was supplemented by qualitative evidence on information strategies and experiences from scenario or vignette interviews. Group exercises in which teachers discussed their responses to specific examples of research information were useful in focusing on strategies for evaluating information. Results While survey respondents were, on balance, positively motivated towards the use of research evidence, their actual use of information from research was limited. They considered the most prominent barriers to their use of research information were associated with lack of time and lack of ready access to sources. This is likely to be a limiting factor in terms of the development of teacher confidence in finding, evaluating and using the kinds of information sources which are increasingly available to support their professional development. In fact survey evidence from the more research-motivated sample indicated that teachers were considerably less confident in finding and using research information than general information. Their confidence was slightly higher in finding research information (e.g. 67.1% and 60.9% were either confident or very confident in defining information needs and locating information respectively) compared to using research information (for example, 56.5% were either confident or very confident in organizing and synthesizing information). However, evidence from the more mixed interview and group exercise samples also revealed a range of concerns about lack of skills and knowledge needed to search and evaluate information effectively. Conclusions The findings suggest that information literacy may be a factor in limiting the use of research information, exacerbating the perceived challenges of lack of time and lack of ready access to information sources. From an information perspective, teachers' use of research evidence is likely to be enhanced by greater development of information literacy; more attention to local information dissemination strategies; and the development of an information culture and ethos within schools. 相似文献

This concluding paper examines the contributions in this Guest Issue by locating them within the ongoing debates about the role and contribution of social science research, particularly through the production of journals. Set in the context of on-going attacks on the relevance of social science research and the failure to respond to major crises that affect us all, I argue that the field of educational leadership is an important site for showing the dangers of becoming relevant and accepting that a constructed crisis is a crisis. I argue for intellectual work within the field of educational leadership, and use the critical and socially critical traditions to illuminate this. The papers in this Guest Issue are located in these traditions, and so I examine the contribution made through problematising educational leadership, examining the realities of working lives in schools and conceptualising alternative ways of thinking about professional practice. 相似文献

Long-term ethnographic data on the daily lives of undocumented students, their teachers, and administrators reveal the effects of fear of deportation (De Genova,?2002) on the routine of a high school. Thirty years after Plyler v. Doe guaranteed the educational rights of undocumented students, this study finds many factors contributing to the creation of a Circle of Silence around these students’ rights and access to schooling that threatens the educational opportunities of a significant population of immigrant students. The implications of this study reveal how schools can become a space to interrupt this vicious cycle through awareness, counseling, and advocacy. 相似文献

The United States Court of Appeals for the District of Columbia Circuit recently heard a suit brought against the Federal Communications Commission by Verizon concerning the 2010 Open Internet Rules. These rules were meant to protect consumers and ensure net neutrality by Internet service providers (ISPs). The Court struck down these rules, and now ISPs will have more power about how content is delivered to users. Librarians should be knowledgeable of net neutrality and this ruling, as it potentially affects abilities of users to exercise intellectual freedoms and could impact the library’s ability to provide services to its users. 相似文献

AbstractLibraries are bridges between information and the library user in the context of information retrieval. Library users want to access information resources according to their topic. Therefore, it is important to create subject entries in bibliographic records. If subject added entries and their redirects are done correctly, it will make it easier for users to access the information they are looking for. In this article the collaborative studies and projects made in Turkey are being discussed. 相似文献

The article discusses the Jagiellonian Library's scanned version of its catalog of books published up to 1949. This case study analyzes the issue of information management in light of the history of the catalog from 1802 onwards and the process of making the catalog accessible via the Internet. It examines the consequences of the decision to scan the catalog on the various library departments' current procedures, as well as on library users. 相似文献
