Google's initiative to scan and add book content into its search engine has resulted in much praise and protest. Changing its digitization project's name from Google Print to Google Book Search and adding information to its site did not keep Google out of copyright court. However, publicity surrounding this project has spawned renewed interest in book digitization projects, with collaborative efforts quickly growing. This article will look at Book Search's history, highlight how it has been altered along with its name, and point out other interesting book digitization projects that Book Search has spawned or recently brought into the limelight, such as those associated with the Internet Archive. 相似文献

国外Web Archive研究与实践进展 总被引:2,自引:2,他引:0
Web Archive采集并保存Web内容,满足当前和未来的访问和使用,其重要性已得到图书馆、档案馆、政府、企业等机构的广泛认可.本文在文献与网络资源调研的基础上,以Web采集、Web Archive的保存、访问和使用为主线,构建了一个系统化的研究框架,并在此框架下梳理国外的相关研究与实践进展.国外的研究与实践值得国内借鉴,如:多主体参与、广泛的交流与合作、注重标准和规范的建设、构建类型多样的Web Archives、对访问与使用的优化等方面,但该领域仍面临法律与伦理、新Web应用内容的归档、存档内容的长期保存、存档内容的多元化应用等问题和挑战. 相似文献

Scientific literacy is an important goal for science education, especially within controversial socioscientific issues. In this study, we analysed 143 students' research reports about stem cell research (SCR) for how they addressed specific source evaluation criteria provided within the assignment. We investigated students' opinions about SCR, how they used the evaluation criteria to evaluate online sources and whether the evaluation criteria and/or the specific sources influenced their opinion and/or understanding of SCR. We found that most of the students supported some form of SCR and reported that their sources were credible and contained more factual information than opinions. Students critiqued the language of the authors, as well as status in their respective fields, along with the content within each source. Additionally, students reported that their sources influenced their content knowledge, but had little influence regarding their SCR opinions. Through this work, we present a new working model and suggest the need for additional research about the understudied interface of opinion, understanding and evaluation within the context of important socioscientific issues. Students' opinions and content knowledge, located at the model's centre, influence and are influenced by the research topic, the sources used, the evaluation criteria and the evaluation of the sources that students use to provide evidence for claims. 相似文献

网络的出现和发展及由此带来的网络环境,既给思想政治教育带来新的挑战,又为其发展提供新的条件。网络环境下思想政治教育是根据网络环境的特征以及关系而确定的,其内容由思想观念、政治观点和道德规范三方面的体系所构成;应遵循科学性与价值性相结合、渗透性和主体性相结合以及隐性教育和显性教育相结合的原则。 相似文献

The intent of this investigation was to learn what factors may have contributed to low usage of a small set of reputable open access scholarly journals, as evidenced in graduate student reference lists. Inquiry into differences among open access sources referenced between 2005 and 2014 revealed that non-indexed journals were being used notably fewer times than their commercially indexed counterparts. A comparison of HTML source code between indexed and non-indexed journals illustrated that certain metadata and other coding features may have affected the visibility of non-indexed journal content. The study suggests to librarians the presence of less visible empirical literature on the web and to smaller, independent academic publishers, the need to apply better quality metadata and optimization strategies to their open access journal content. 相似文献

Response rates, response time, and costs of mail and electronic surveys were compared. The survey sample consisted of college faculty in the southeastern United States. Mail surveys yielded a higher response rate and a lower rate of unde-liverable surveys. However, receipt of responses was significantly quicker for those delivered electronically, with over 80% of initial responses arriving before receipt of the 1st returned mail survey. The costs associated with distribution of surveys and preparation of data for analysis were much lower with the electronically delivered surveys. 相似文献

For many reasons, students with disabilities are not as thoroughly represented in science careers as are their nondisabled peers. In this case study, the authors explore the effects an informal education program focused on environmental science and delivered to college-bound students with disabilities had on comfort level with science and interest in science careers. Results indicate that the informal nature of the program was well-received and increased individuals' confidence in their science ability. The authors present suggestions for translating this experience into a traditional classroom setting. 相似文献

Although the Internet has been touted as a boon to social studies education, little research exists that documents the impact of using it as a contextualizing tool for analyzing primary sources and developing Web sites on high school students' achievement. In this article, the authors address both issues by using a quasi-experimental design to measure impact on student achievement. However, there was no appreciable difference in student achievement, and the provided assignment and amount of content that students were expected to learn in the unit of study may have hindered higher-order thinking. The authors discuss the implications of these findings. 相似文献
