As critical components of the aging continuum of care, senior centers promote older adult health and well-being by providing opportunities for recreation, socialization, nutrition, health education, and access to vital social services. Nationally, a vast network of 11,000 senior centers serves over four million older adults annually. As the United States population ages rapidly, public funding, which is the primary source of support for a majority of senior center services, has remained stagnant. If senior centers are to continue to effectively serve older adults and meet their comprehensive needs, they need to demonstrate their relevance to the community and advocate for increased funding support. This paper explores the policy concerns of senior center administrators, investigates their efforts to influence public policy, illustrates advocacy techniques currently utilized by them, and highlights the learning needs of administrators in this regard. Practice implications for senior centers, their constituents, and gerontological education are provided. 相似文献

Media education forms part of the National Minimum Curriculum of England, Malta and Germany. Teacher training courses differ greatly in how teachers are prepared to teach media education. In this paper we shall investigate the attitudes of a sample of teachers trained in England, Malta and in Germany towards their perceived importance of media education and the teachers' preparedness to teach the subject. This preliminary study had a sample of 132 participants, 33 teachers from England, 47 from Germany and 52 teachers from Malta. The tool used to collect data was an online questionnaire. The results show that teachers taking part in this study were not given enough training, or any training at all to be able to teach media education with the result that they do not feel sufficiently prepared to teach the subject. It is suggested by the authors that media education becomes a compulsory component of the initial teacher training courses as well as advanced training for teachers. 相似文献

Strategies student-teachers employ in classroom interaction with pupils during teaching practice periods are surprisingly understudied, considering that the teaching practicum provides a central arena for student-teachers learning to become teachers. This study investigates the primary strategies student-teachers utilised in classroom interaction and the multiple qualities of these strategies. The data were collected from 31 student-teachers during their teaching practicum through stimulated recall (STR) interviews focusing on challenging and empowering critical incidents that student-teachers chose from their video-recorded lessons. The results showed that in challenging classroom incidents, student-teachers applied predominantly reactive behavioural strategies, whereas in the empowering situations, student-teachers primarily employed proactive cognitive and behavioural strategies. Use of proactive cognitive strategies was typically associated with positive meaningful experiences; hence, they setting the stage for utilising a more diverse set of proactive strategies in the classroom. Implications for teacher education programmes providing student-teachers authentic learning opportunities that promote proactive strategies are discussed. 相似文献

This paper examines the exploitation of inertial measurements to analyze javelin throwing mechanics. The main objective was to demonstrate that consumer-grade inertial navigation systems, augmented with some position and attitude data obtained from a video sequence, yield detailed information of the mechanics of javelin throwing. Especially, such a system makes it possible to analyze the momentary force and power exerted on the javelin during the acceleration phase. Although the presented system is a pilot, leaving space for further improvements, it already reveals the potential of inertial navigation systems to sports. In practise, an inertial measurement unit was embedded inside the tip of the javelin to determine the javelin’s momentary attitude, position, and velocity. Graphs on the speed and angular velocity about the longitudinal axis of the javelin during the whole performance are presented. The maximum estimated release speed and release angular speed were 28.02 m/s and 215.9 rad/s, respectively. The acceleration phase trajectory of the javelin and its deviation from a straight line path are demonstrated. Additionally, the momentary forces and powers are shown and the effect of aerodynamic forces on the projectile is specified. The magnitude of the maximum tangential forces and accelerating powers were 364 N and 9.76 kW. The duration and length of the acceleration phase trajectory varied between 223 and 231 ms, and 2.48 and 2.75 m. To estimate the accuracy of the inertial measurements, the acceleration phase results were compared to measurements made with high-speed cameras. 相似文献

Computing education has been an important and sometimes contentious issue ever since the advent of modern computing. Debates about computing education have closely followed job markets, technological development, academic interests, societal concerns, and changes in the perception of computing. The themes in computing education debates can be characterized by emergence and formation, standardization and organization, accommodation to change, and divergence. The focus of computing education has expanded outward from the computer to programming, algorithms, and information, as well as to the organizational, social, and cultural environment of computer systems.
This survey gives computing education researchers an overview of some of the central issues and disputes in computing education over the brief history of modern computing. The survey highlights the emergence of educational initiatives, concepts, joint efforts, and institutions of computing education, and outlines the relatively short history of computing education research. The survey is structured around four overlapping themes: computing education as technological training, as training for software development, as a central element for the field’s academic recognition, and as training for computational problem-solving in any domain of knowledge. Each theme has played a role throughout the history of modern computing, but their relative emphases have changed over the years. 相似文献

This paper explores a particular aspect of journalistic quoting, monologisation. During monologisation, the interactive turn exchange between the journalist and the interviewee is simplified in the resulting article. This simplification process mainly takes the form of obscuring the role of the journalist in the original spoken discourse. As a result, the quotations appear to be unprompted, continuous utterances by the interviewee, and this in turn has seminal consequences for the interpretation of the quotation. This paper will demonstrate that monologisation is an effective means for journalists to steer the reading of the article and to include their own points of view without breaking the professional rule that journalism must separate facts from opinions. The results of this study are based on a comparison between two types of empirical data; recordings of journalistic interviews, on the one hand, and published articles, on the other. This study will focus on one particular type of journalistic interview that has been largely neglected in prior research along with its specific quoting practices, namely the interviews were conducted by the journalists in order to collect raw material for written journalistic items, published either in print or electronic form. This paper will show that interviews of this type involve highly diverse and mutually adaptive interaction, contrary to the clearly structured question–answer interviews that are used as sound bites in television news items and have thus far remained the primary focus of research on both journalistic interviews and quoting processes. The notion of monologisation could be applied in various domains where an interview is converted into a written account, such as research interviewing and police interrogations. 相似文献

This article provides a cross‐national perspective on successful school principalship in three countries derived from an analysis of case studies in the International Successful School Principalship Project (ISSPP). The ISSPP aims to investigate the characteristics, processes and effects of successful school leadership across eight countries (i.e. Australia, Canada, England, the United States, China, Denmark, Sweden and Norway). Examples from the USA, Norway and China (Shanghai) were selected to illustrate cross‐national differences related to the societal purposes of education, the structure and funding of different national educational systems and the influence of particular governmental educational policies (i.e. accountability‐oriented policies) on the leadership practices of individual school principals. Variations in selection criteria and research procedures were also noted. Recommendations for further research using a cultural framework include analysing multiethnic schools to identify culturally specific leadership practices as well as developing further ISSPP case studies in non‐Western contexts. 相似文献

We indicate the size of family background effects in Sweden, Finland, and Estonia – countries that differ in both the rhetoric and extensiveness of the system-level school choice policies. Family background effect is defined as the dependence of student achievement on family background characteristics, such as parental education, income, and social status. The number of books at home is used as a proxy when operationalising family background, and its effect is measured as a percentage of individual-level PISA scores. Fixed-effect regression results reveal that family background remains a powerful determinant in the educational results of 15-year-old students in all three cases, being largest in Sweden. Furthermore, we show how the family background effect is moderated by school-level choice policy, that is, how students and schools are matched. The analysis reveals that zoning policies have statistically significant negative effects on the impact of the family background effect, independent of country-level policies. 相似文献

The University of Oulu in northern Finland is a regional university that is not only surviving but developing during an era of economic turmoil. Its secret of success has been, first of all, to fulfil its regional mission, developing specialities, like northern studies, for which its geographical position gives it an advantage. But it has also developed co‐operation links with nearby Finnish and Russian universities as well as with one Swedish and one Norwegian university. Finally, it has been able to establish good working relations with certain specialized Finnish government research and development centres in northern Finland. Having both mission and vision statements and being guided by them are important to the University of Oulu in generating management/staff/community/region synergy. 相似文献
