科技信息的开放获取已成为影响学术信息交流与科学发展的重大问题,深刻地影响到科技政策、科技支撑环境发展战略和科技信息服务模式。一大批科学家、科研机构和许多国家的科学管理与科研资助机构,都积极地推动科技信息的开放获取。他们或者制定开放获取政策、要求或鼓励科研人员提供科研成果的开放获取,或者支持开放出版期刊,或者建立机构开放存储库、支持本机构科研成果开放获取。通过这一系列的措施,科学界希望能够促进科研成果不受限制地广泛传播和自由获取、以及促进科研成果通过公共机制长期可靠保存和利用,以保障科技知识资产的国家保护和科研机构的知识资产管理。 相似文献

This article reviews the Invisible Farmer project – the largest study of Australian women on the land – a third of the way through its three year funding period. It introduces the aims of this collaborative and multidisciplinary project, focusing on the role of records and oral histories in the creation of new narratives, and the task of raising public awareness of the important historical and contemporary contributions made by Australian women farmers. We examine the way digital platforms work to curate records and promote research, and outline the important role that the Australian Women’s Register, a core project of the Australian Women’s Archives Project, will play in achieving outcomes. 相似文献

Virtual and Augmented Realities are advancing technologies that are becoming more popular in gaming and programming communities. However, virtual reality has been in development for decades. As libraries are often at the forefront of offering new and advancing technologies to their communities, virtual and augmented reality programs have become new additions to library services. While gaming is the prominent use of these technologies, virtual and augmented reality affords many educational opportunities. Mississippi State University Libraries have recently added a virtual/augmented reality lab as part of its library program. 相似文献

Abstract Students develop robust mental models of teaching and learning during their school years, and as such, often teach as they were taught—possibly perpetuating practices that limit intellectual inquiry in classrooms. This paper reports on an analysis, using a conceptual framework and NUD?1ST software, of a cohort of 3rd‐year teacher education students' reflections on changes in their mental models following their experiences in a problem‐based learning (PBL) topic. Results provide evidence that students do report changing mental models in areas such as (a) the value of case studies for engaging with subject content, motivating learning, and connecting theory with practice; (b) self‐reflection and peer collaboration for cognitive and professional growth; and (c) processes of inquiry for developing self‐regulated learning practices. 相似文献

This study presents a worked example of a stepped process to reliably estimate the habitual physical activity and sedentary time of a sample of young children. A total of 299 children (2.9 ± 0.6 years) were recruited. Outcome variables were daily minutes of total physical activity, sedentary time, moderate to vigorous physical activity and proportional values of each variable. In total, 282 (94%) provided 3 h of accelerometer data on ≥1 day and were included in a 6-step process: Step-1: determine minimum wear-time; Step-2: process 7-day-data; Step-3: determine the inclusion of a weekend day; Step-4: examine day-to-day variability; Step-5: calculate single day intraclass correlation (ICC) (2,1); Step-6: calculate number of days required to reach reliability. Following the process the results were, Step-1: 6 h was estimated as minimum wear-time of a standard day. Step-2: 98 (32%) children had ≥6 h wear on 7 days. Step-3: no differences were found between weekdays and weekend days (P ≥ 0.05). Step-4: no differences were found between day-to-day variability (P ≥ 0.05). Step-5: single day ICC’s (2,1) ranged from 0.48 (total physical activity and sedentary time) to 0.53 (proportion of moderate to vigorous physical activity). Step-6: to reach reliability (ICC = 0.7), 3 days were required for all outcomes. In conclusion following a 7 day wear protocol, ≥6 h on any 3 days was found to have acceptable reliability. The stepped-process offers researchers a method to derive sample-specific wear-time criterion. 相似文献

This paper explores the perceived parental influence (PPI) on mathematics learning among over 700 students across three year levels (Years 5, 7, 9) in China and Australia. It was found that the PPI of students was less strong as year levels increased in both countries. Students in China had stronger perceived parental encouragement and higher perceived parental educational expectation than students in Australia. The PPI of students from different home language backgrounds was also investigated. Students in China demonstrated stronger perceived parental encouragement and parental expectation than English speaking students and other language speaking students in Australia, and they also demonstrated stronger perceived parental expectation than Chinese speaking students in Australia, and similar perceived parental encouragement. Within the three groups of students in Australia, Chinese speaking students and other language speaking students demonstrated similar levels of perceived parental encouragement and expectation, but they both demonstrated a higher level of perceived parental encouragement and expectation than English speaking students. Possible reasons for the similarities and differences between the different groups of students were discussed. 相似文献

This paper argues that teachers' recognition of children's cultural practices is an important positive step in helping socio‐economically disadvantaged children engage with school literacies. Based on 21 longitudinal case studies of children's literacy development over a 3‐year period, the authors demonstrate that when children's knowledges and practices assembled in home and community spheres are treated as valuable material for school learning, children are more likely to invest in the work of acquiring school literacies. However, they also show that while some children benefit greatly from being allowed to draw on their knowledge of popular culture, sports and the outdoors, other children's interests may be ignored or excluded. Some differences in teachers' valuing of home and community cultures appeared to relate to gender dimensions. 相似文献
