There are many assumptions about the ways in which textbooks and other learning and teaching support materials (LTSM) can contribute to improved learning outcomes in many international contexts. These can focus on ways that they can implement the school curriculum, often in lieu of good pedagogical practice. Drawing on case studies from Rwanda and South Africa, the complexity of the role of LTSM as part of classroom enactment is shown. The discussion suggests that there are enabling factors to this including support for teachers’ use of LTSM and the availability of materials to all learners. A framework is presented in which LTSM, teachers and learners can become equal partners in teaching and learning, but only when adequate language and other pedagogical support structures are provided. Conclusions consider the potential impact for LTSM use when it is elevated to a medium that is accessible and useful to both teachers and learners. 相似文献

In this article, a group of nontraditional and/or doctoral students of color and our advisor discuss how the advisor-advisee mentoring relationship has positively affected our experiences within academia. The mentoring relationship, cultivated within a group mentoring model, was integral to our acclimation of the hidden culture of our doctoral programs. We elaborate on the history and mentoring model of the group of which we are a part, and follow with a review of the literature on mentoring practices and a discussion of methodology. Finally, through autoethnographic vignettes, each author discusses his/her experience as a non-traditional and/or student of color and how our relationship with the group has provided us with the logistical, emotional, and psychological support needed to progress in and complete our programs. 相似文献

It is shown that in the case of charged beams of finite dimensions and/or finite electromagnetic wave-guiding structures, the condition v&c/n is a necessary but not a sufficient condition for generation of Cerenkov radiation. Depending upon the modulation, size and geometry of the beams, and dimensions of the wave-guiding structures, selected lines can be eliminated from the radiation spectrum. Since the lines in the spectrum are size and geometry dependent it is suggested that the analysis of the Cerenkov radiation spectrum may be utilized in the determination of sizes and shapes of charged particles. 相似文献

OBJECTIVE: This study examined how childhood history of discipline (1) related to ratings of how severe and typical punishments were; and (2) predicted parents' use of discipline techniques. The influence of child culpability on these ratings was also investigated. METHOD: Ninety-nine New Zealand parents rated 12 physical discipline scenarios varying in discipline severity and perceived child culpability. Parents judged how severe and typical they considered the disciplines depicted in the scenarios and reported on how often they had experienced such discipline as children and how often they had used them with their own children. RESULTS: When the child was perceived to be at fault, parents rated the discipline depicted as less severe, considered the technique more typical, reported they had been similarly disciplined more frequently, and applied such discipline to their child more frequently. Childhood history of a discipline was related to the parent's use of that method, and the parents judged techniques they used with their own children as less severe and more typical of methods of discipline. History of discipline and severity judgments were the best predictors of parents' disciplinary practices. CONCLUSIONS: Although the findings support the cycle of violence theory, more complex potential pathways to abusive parenting, including the variables in this study, are proposed. 相似文献

Increasing diverse author representation within medical librarianship scholarship among BIPOC information professionals is an important endeavor that requires closer examination. This commentary looks to examine the ways in which the profession can support Latinx librarians and library workers in fully participating within the scholarly pipeline by exploring our unique and authentic voices, structural barriers, hesitation and fears, Whiteness in the profession and knowledge production, bias in the peer review process, lack of resources and support, and finally, a call to action. 相似文献

Clean air policies in China have substantially reduced particulate matter (PM2.5) air pollution in recent years, primarily by curbing end-of-pipe emissions. However, reaching the level of the World Health Organization (WHO) guidelines may instead depend upon the air quality co-benefits of ambitious climate action. Here, we assess pathways of Chinese PM2.5 air quality from 2015 to 2060 under a combination of scenarios that link global and Chinese climate mitigation pathways (i.e. global 2°C- and 1.5°C-pathways, National Determined Contributions (NDC) pledges and carbon neutrality goals) to local clean air policies. We find that China can achieve both its near-term climate goals (peak emissions) and PM2.5 air quality annual standard (35 μg/m3) by 2030 by fulfilling its NDC pledges and continuing air pollution control policies. However, the benefits of end-of-pipe control reductions are mostly exhausted by 2030, and reducing PM2.5 exposure of the majority of the Chinese population to below 10 μg/m3 by 2060 will likely require more ambitious climate mitigation efforts such as China''s carbon neutrality goals and global 1.5°C-pathways. Our results thus highlight that China''s carbon neutrality goals will play a critical role in reducing air pollution exposure to the level of the WHO guidelines and protecting public health. 相似文献
