Higher education institutions are trying to provide more flexibility and individualization, which is mainly realized through the use of new technologies and implemented in online or blended learning designs. This systematic review aims to investigate the impact of replacing classroom time with an online learning environment. The meta-analysis (k = 21 effect sizes) applied strict inclusion criteria concerning research design, measurement of learning outcomes and implementation of blended learning. The estimated effect size (Hedge's g) was positive, although not significantly different from zero and the confidence interval [-0.13, 0.25], suggesting that overall differences between blended and conventional classroom learning are small, and, at best, very small negative or moderate positive effects are plausible. This means that despite a reduction in classroom time between 30 and 79 per cent, equivalent learning outcomes were found. Consequently, blended learning with reduced classroom time is not systematically more or less effective than conventional classroom learning. 相似文献

In an increasingly globalized and culturally diverse world, extended stays abroad during high school are considered important opportunities for acquiring and improving a variety of skills, most importantly, language achievement. This study examines both predictors and effects of studying abroad in an English-speaking country during high school, using population data from the second largest city in Germany (N = 5361; 13% went abroad). In order to determine the most central predictors of studying abroad, we employed logistic regression models in which students’ socioeconomic background emerged as the strongest predictor of studying abroad. To test the effects of studying abroad, we applied propensity score matching. Studying abroad had positive effects on standardized achievement, grades, and course choice in English, whereas it had hardly any effects on outcomes in math. Implications for studying abroad during high school and future research directions are discussed. 相似文献

The article documents findings from a pilot study undertaken in 2012–2013 in a special needs secondary school in the England, that trialled the use of a multimedia advocacy tool, “The RIX Wiki”. The trial was part of the pathfinder programme, which aimed to reform existing Special Education Needs provision, from the system of statementing to one of developing education health care plans. The reforms became enshrined in the Children and Families Act (2014). The findings were overall positive and helped with person-centred planning processes. The discussion is framed within current and future policy directives. We argue that multimedia advocacy approaches and software tools, like the “RIX Wiki” will have a continued role to play in ensuring the needs, aspirations and choices of children and young people with learning disabilities remain central. 相似文献

The notion that the stories of our lives shape dispositions towards imagined futures is another lens through which university underrepresentation should be viewed. A storied lens attends to how futures, like university attendance, are storied during childhood to the extent that some youth imagine, and therefore plan, these futures as natural progression. Such was the case for study participants, indicating that childhood stories contain answers for mitigating social reproduction connected to parental education and cultural forces within the home. Examining social mobility through the underexplored storied-futures grand narrative presents unique solutions that lay hidden within the dominant meritocratic grand narrative. 相似文献

体医融合和非医疗健康干预可以有效促进疾病管理与健康服务模式的形成,但体医融合项目治理初期仍然受到理念融合、体医融资、部门协同等因素的影响。该文以病毒、人体免疫与体育运动的体医融合关系视角,依据共生理论对体医融合项目的风险治理逻辑进行了阐述。采用文献资料法、数理统计法等对体医融合项目风险治理的相关个案进行了整理,并基于NVIVO11.0质性分析软件对体医融合个案进行识别分析,构建了体医融合项目风险治理的影响因素评价指标体系,包括13个一级指标30个二级指标。最后提出了体医融合项目风险治理的路径选择(1)将体医融合理念提升至构建公共卫生保障体系战略的高度;(2)落地变现体医融合项目购买方案;(3)打造政府精准购买体医融合项目区块链。 相似文献

ABSTRACT
Purpose
The 24-Hour Movement Guidelines (24 hMG) provide specific recommendations, including physical activity (PA), screen-time and sleep-duration, which preschoolers should achieve for a healthy day (24 h).

AbstractIn 2016, J. Murrey Atkins Library at the University of North Carolina at Charlotte opened a reservable study room where student parents and caregivers can study with their children on campus. In 2018, the library opened a second family-friendly study room to meet the needs of our growing campus community. To inform the room design, the library conducted a mixed methods research study that included a user survey, an examination of room reservation and usage data, and one-on-one user interviews. This paper focuses on the user-centered design process used to inform the development of the second, family-friendly, library study room. 相似文献

Abstract Supporting global health priorities through the development of robust health science librarianship partnerships is of significant importance. Increased demand for synthesizing evidence-based information, collating quality resources, and increasing research productivity to improve human health requires integration of library and information science skills and expertise. The Health Sciences Library (HSL) at the University of North Carolina at Chapel Hill (UNC), exists to be an indispensable partner in health information and knowledge, teaching and learning, and research. As global efforts at UNC expanded, the HSL sought to ensure that our global engagement strategy and integration were aligned with campus priorities and partner needs. The HSL created a global research partnership plan: identify resources that improve efficiency, increase access to information, build in-country capacity and expertise—all while strengthening collaborations across multiple countries. Creating a meaningful and sustainable engagement strategy was central to envisioning our path forward and can be used as a framework for consideration by librarians in similar settings. 相似文献
