Many western countries are paying increasing attention to the organization and administration of graduate studies. Such attention has developed from primary concerns about completion times, completion percentages, programme quality, and student quality, as well as secondary concerns about supervisors, funding, coursework, inter-organizational co-operation, and policies and practices of both universities and research councils. Using information about British graduate programmes as a basis, the article presents policy issues related to research councils, funding councils, and control, followed by discussion of the themes of the nature of programmes, supervision and evaluation, completion time, quality, and innovation. The final sections address several concerns and offer some suggestions. 相似文献

We trace the development and analyze the generalizability of the Classroom Assessment of Sociocultural Interactions (CASI), an observation system designed to measure cultural dimensions of classroom interactions. We establish CASI measurement properties by analyzing panoramic videos of 4th and 5th grade classrooms from the Measures of Effective Teaching project, and argue for its significance in terms of achievement opportunity for minoritized students and needed evidence regarding equitable teaching. We frame ten dimensions of sociocultural interactions within three domains: Life Applications (i.e., connections with what students know and do outside of school); Self in Group (i.e., interdependence to motivate learning and foster social identities); and Agency (i.e., how freedom and choice are managed).
We demonstrate how measurement error is associated with raters, lessons, and lesson segments, and discuss implications for CASI refinement, as well as appropriate instrument uses to enrich learning opportunities for minoritized students across a variety of classroom settings. 相似文献

Nullis in verba was chosen as the motto of the Royal Society, as it embodied the culture of transparency and collaboration that were the hallmarks of the Royal Society and of the scientific method it promoted. Communication, using the tools of the day, was essential to this community of scientists as they created and shared new knowledge. Almost three hundred years later, libraries continue to advance principles relating to the importance of collaboration and transparency. This two-part article series, published jointly in International Information and Library Review and Technical Services Quarterly explores notions of transparency and collaboration in research and how these ideas are impacting the world of librarianship – from information creation, organization and access perspectives. 相似文献

A number of voices have emerged in U.S. political discourse questioning the legitimacy of American exceptionalism, suggesting we are in a “post-American world.” Our research examines the effects that political messages that explicitly challenge American exceptionalism can have on U.S. public opinion. Drawing upon social identity theory, we find that explicit challenges to American exceptionalism significantly impact Americans’ views toward their own nation, their willingness to denigrate foreign publics, and their broader foreign policy preferences. 相似文献

The mere perception that news has given certain problems more coverage can lead the audience to assume that those problems are more important. Given that the news media, at times, obsesses over relatively trivial matters, and given that the audience is increasingly able to filter media exposure, it is worth asking what happens when audience members perceive that recent media coverage has not emphasized any very important problems. In such cases, audience members might assume that any problems facing the nation must not be particularly important. We explicate this attitude of political complacency, test whether perceived media agendas lacking important problems can influence it, and explore whether complacency helps explain political disengagement. We also explore whether these effects generalize beyond news, to new media gatekeepers such as Twitter. Two experiments tested effects of a perceived absence of important problems in recent news or Twitter content. In the case of news, but not Twitter, this increased complacency in both studies. Study 2 added a no-exposure control and found that effects on complacency were driven by the cueing of nonproblem stories, not by the absence of problem story cues. Both studies validated complacency as a predictor of political disengagement. 相似文献

Serious games are becoming increasingly popular due to their association with increased learning outcomes when compared to traditional self-regulated learning activities. However, the majority of research examining the outcomes of serious games has focused almost exclusively on learning outcomes. This has resulted in a lack of research examining why these types of games result in increased positive outcomes, such as engagement or performance. This study seeks to address this gap in existing research by examining the relationship between game difficulty and participants’ engagement, performance and self-efficacy in a Pacman style maze navigation game. This required the use of hidden difficulty variations which participants were randomly assigned. Participants engaged with the game over a 5-days practice period. Results from this study suggest that difficulty plays a considerable role in influencing participants’ self-efficacy for the task. Self-efficacy has been consistently linked to positive outcomes such as increased engagement and performance. This highlights the importance of difficulty as a game design factor as well as providing an insight into the manner in which serious games could be further refined in order to increase user’s self-efficacy and associated positive outcomes. Implications for future serious games and self-efficacy research are discussed. 相似文献
