The purpose of this research was to explore the long-term outcomes of either participating or not participating in early childhood science education on grade 6 students?? conceptual understanding of science. The research is situated in a conceptual framework that evokes Piagetian developmental levels as both potential curriculum constraints and potential models of efficacy. The research design was a multiple case study of grade 6 children from 3 schools in China (n?=?140) who started formal science education in the third grade and grade 6 children from 3 matched schools in Australia (n?=?105) who started learning science in kindergarten. The students?? understanding was assessed by a science quiz and an in-depth interview. The data showed that participating children from the high socioeconomic schools in China and Australia had similar understandings of science. Divergence between the medium and low socioeconomic schools, however, indicated that the grounding in early childhood science education in Australia may have placed these children at an advantage. Alternative explanations for the divergence, including the nature of classroom instruction in the two countries, are discussed.  相似文献

ABSTRACT

Libraries in the Digital Age (LIDA) 2016 takes place every 2 years, and was held this year at the University of Zadar, in Zadar, Croatia, from June 13–17, 2016. Each LIDA, two themes are chosen in advance. This year, the themes were “Digital Curation and Preservation: Current Trends and Research” and “Use Studies, Education, and Training for Digital Library Collections.” A presentation of each theme by university professors and subsequent keynotes relevant to each theme by two world-renowned experts provided context and ensured a shared perspective among LIDA attendees. Conference-goers were presented a balanced approach to theoretical and practical questions in a number of areas of digital libraries, including the presentation of research on information seeking practices among special communities, data mining projects, the exploration of platforms and experiences, and digitization. Additionally, a number of the contributed papers, panels, demonstrations, and workshops spanned the two themes, making for not only an informative conference, but also a particularly rich and coherent experience for attendees. Opportunities for junior researchers were numerous, with the conference priding itself on the mentorship opportunities available. In 2018, you might find yourself tempted to see what LIDA is all about; if you do, you will no doubt find yourself in a breath-taking venue along the Croatian coast surrounded by engaged, supportive, and collaborative researchers and professionals from around the world – in my opinion, you won't regret it.  相似文献

American television programs have been criticized for being filled with images endorsing capitalist consumerism and for being weighted toward the upper middle classes. This study proposed that heavy viewing of these distorted representations may culminate in decreases in viewers' life satisfaction. A path model investigated this supposition, based on material value and social comparison perspectives. Surveys were administered to 225 adults in a northeastern town in the United States, and the data were subjected to path analysis. The findings of this study suggest that heavy television viewing may be associated with material value, estimates of other people's affluence, and perceived gaps between the self and others in material affluence. Of importance, the findings also suggest that the perceived gaps between the self and others may be associated both with dissatisfaction with personal life and dissatisfaction with current social equality, whereas material value may be associated only with dissatisfaction with personal life.  相似文献

Since its inception in 2002, COUNTER has given hope to many librarians charged with collecting usage data for their online collections. This hope turned to optimism in 2007 with the release of SUSHI (Standardized Usage Harvesting Initiative) as a NISO standard (Z39.93). In 2009 release 3 of the COUNTER Code of Practice for Journals and Databases takes effect and with it are some significant advances that will turn hopes and optimism into realities. This article describes the changes and their implications.  相似文献

Ever since OpenURL linking was introduced in 2000 by Herbert van de Sompel the link resolver has played an important role in providing users with access to the online resources they have rights to. From the start, one of the criticisms of OpenURL linking has been that it is not 100% successful—sometimes the user is presented with a link to full text, but that link fails. In 2010 a new National Information Standards Organization (NISO) workgroup was created to tackle the issue of OpenURL quality. This column will discuss this NISO initiative and look in detail at the proposed “Completeness Index” that promises a means of measuring the quality of OpenURLs being submitted by various content providers. The article will also discuss how some OpenURL quality issues may be more perception than reality and how librarians can configure their links and link resolvers to overcome these negative perceptions.  相似文献

ONIX for Publication License (ONIX-PL) was introduced in 2006 with great hope that it would simplify the licensing and license management aspects of e-resource management. However, after several years this standard has not seen significant commercial adoption. Believing this standard still holds promise, the National Information Standards Organization, with funding from the Andrew W. Mellon Foundation and support from Jisc and EDItEUR, has launched the ONIX-PL License Encoding Project. The goal of the project is to accelerate adoption by creating and making publicly available a set of publisher licenses encoded to the ONIX-PL standard. In this column we provide more details on the project, its goals, challenges, and prospects.  相似文献

The Counting Online Usage of Networked Electronic Resources (COUNTER) Code of Practice and Standardized Usage Statistics Harvesting Initiative (SUSHI) are two standards whose successful adoption will greatly assist librarians in performing accurate and timely usage analysis of their online collections and thus make more informed collection management decisions. Variations in how these standards have been applied by content providers to their SUSHI and COUNTER implementation are currently impacting their widespread adoption. The standards themselves are not broken—what is needed is concise guidelines on their implementation. This column reviews some of the roadblocks that impede consistent implementation of these standards as well as proposes recommendations that could form the basis of a community profile for these standards.  相似文献
