Blended learning has become increasingly common in higher education. Recent findings suggest that blended learning achieves better student outcomes than traditional face‐to‐face teaching in gross anatomy courses. While face‐to‐face content is perceived as important to learning there is less evidence for the significance of online content in improving student outcomes. Students enrolled in a second‐year anatomy course from the physiotherapy (PT), exercise physiology (EP), and exercise science (ES) programs across two campuses were included (n = 500). A structural equation model was used to evaluate the relationship of prior student ability (represented by grade in prerequisite anatomy course) and final course grade and whether the relationship was mediated by program, campus or engagement with the online elements of the learning management system (LMS; proportion of documents and video segments viewed and number of interactions with discussion forums). PT students obtained higher grades and were more likely to engage with online course materials than EP and ES students. Prerequisite grade made a direct contribution to course final grade (P < 0.001) but was also mediated by engagement with LMS videos and discussion forums (P < 0.001). Student learning outcomes in a blended anatomy course can be predicted the by level of engagement with online content. Anat Sci Educ 11: 471–477. © 2017 American Association of Anatomists.  相似文献

The current explosion in mobile computing and telecommunications technologies holds the potential to transform \"everyday\" time and space, as well as changes to the rhythms of social institutions. Sociologists are only just beginning to explore what the notion of \"mobility\" might mean when mediated through computing and communications technologies, and so far, the sociological treatment has been largely theoretical. This article seeks instead to explore how a number of dimensions of time and space are being newly reconstructed through the use of mobile communications technologies in everyday life. The article draws on long-term ethnographic research entitled \"The Socio-Technical Shaping of Mobile Multimedia Personal Communications,\" conducted at the University of Surrey. This research has involved ethnographic fieldwork conducted in a variety of locales and with a number of groups. This research is used here as a resource to explore how mobile communications technologies mediate time in relation to mobile spaces. First the paper offers a review and critique of some of the major sociological approaches to understanding time and space. This review entails a discussion of how social practices and institutions are maintained and/or transformed via mobile technologies. Ethnographic data is used to explore emerging mobile temporalities. Three interconnected domains in mobile time are proposed: rhythms of mobile use, rhythms of mobile use in everyday life, and rhythms of mobility and institutional change. The article argues that while these mobile temporalities are emerging, and offer new ways of acting in and perceiving time and space, the practical construction of mobile time in everyday life remains firmly connected to well-established time-based social practices, whether these be institutional (such as clock time, \"work time\") or subjective (such as \"family time\").  相似文献

The discovery of small RNAs that can turn off genes has given us a new way to think about how genes are regulated. These molecules are present in all complex organisms and are thought to regulate upwards of 30% of human genes. Due to their small size, their discovery was surprisingly recent and was underappreciated initially. Beginning with two back-to-back papers published in 1993, the labs of Victor Ambros and Gary Ruvkun reported the first small RNA (now known as a microRNA or miRNA) and how it regulated a target mRNA in the roundworm Caenorhabditis elegans through base-pairing interactions. It took until 1999 for another report to document novel small RNAs in complex systems, when David Balcoumbe discovered similarly sized molecules, now known as small interfering RNAs or siRNAs, that were associated with shutting off or “silencing” genes in plants. A frenzy of reports on small RNAs and their roles in turning off genes ensued with many researchers including Ambros, Ruvkun, and Baulcombe prominently participating. Almost instantly it became clear that small RNAs were not a quaint oddity exclusive to the worm, and molecular biology was never the same. Now we know that these molecules are critical for normal growth and development, are associated with cancer and other diseases, and have tremendous applied potential to improve agriculture and human health.  相似文献

This study examined associations between maltreatment and early developmental vulnerabilities in a population sample of 68,459 children (Mage = 5.62 years, SD = .37) drawn from the Australian state of New South Wales, using linked administrative data for the children and their parents (collected 2001–2009). Associations were estimated between (a) any maltreatment, (b) the number of maltreatment types, and (c) the timing of first reported maltreatment and vulnerability and risk status on multiple developmental domains (i.e., physical, social, emotional, cognitive, and communication). Pervasive associations were revealed between maltreatment and all developmental domains; children exposed to two or more maltreatment types, and with first maltreatment reported after 3 years of age, showed greater likelihood of vulnerability on multiple domains, relative to nonmaltreated children.  相似文献

Rural schooling has remained a concern for policy‐makers, employers, teacher education providers and schools throughout our recent history. In particular, the allegedly variable quality of teaching and learning in rural Australia is a major concern for teacher educators and educational leaders alike, with the provision of quality services for rural Australians a major equity issue in social as well as political terms. Working from an explicitly situated perspective, this paper explores these issues in relation to a set of current and recent research projects and government reports, with particular reference to a study currently exploring the articulation of teacher education and rural schooling in New South Wales. This is contextualized within a larger agenda of national and environmental sustainability which raises the key issue of social policy and educational priorities as we look forward into a radically uncertain future for teacher education, rural schooling and rural‐regional sustainability.  相似文献

“FRIENDS for life” is a manualised, 10 week, Cognitive Behavioural Therapy (CBT) based programme designed to be run in school and community settings. The aim of this study was to evaluate the impact of “FRIENDS for life” when implemented in a mainstream secondary school by school staff. Data regarding implementation of the programme were collected and analysed using activity theory. A Single Case Experimental Design was used to monitor the impact of the intervention on the emotional distress and coping strategies of five secondary school participants. The findings suggest that participation in FRIENDS did not result in the hypothesised reductions in emotional distress, or improvement in coping skills. However programme implementation was incomplete. Analysis using activity theory suggested that factors such as lack of time, space for delivery, and experience and training impacted upon implementation and could be further supported by educational psychologists when developing these interventions.  相似文献
