ERIC数据库是教育领域中最大、最负盛名的国际级教育类资料库。ERIC数据库收录的远程教育类研究成果始于1972年,截至2010年,共12402篇文献。这些文献通过文献计量分析发现：国外远程教育研究已步入研究成果产出相对稳定的成熟期;文献来源渠道众多,以学术期刊为主;文献类型丰富,以期刊论文和研究报告为主;研究内容广泛,教育层次、教学设计、教学方法、相关技术的研究以及技术在远程教育中的应用研究一直是该领域的重点研究内容。当前国外远程教育的应用已经发展到大学以及研究生教育,研究逐渐向传统教育转变,开始关注教育政策、师生关系、互动、混合学习以及新技术在远程教育中的应用。 相似文献

Access to scholarly information in the disciplines of education and medicine occurred primarily through the simultaneous development of two bibliographic databases. The Education Resource Information Center (ERIC) originated as a resource designed to be comprehensive in its inclusion of peer-reviewed and unpublished literature for the entire education community. MEDLINE began as a resource of selective materials for physicians and researchers. Today, ERIC includes selected peer-reviewed literature directed primarily to researchers and practitioners, although others use the database, while MEDLINE is a vast information system serving all health professionals and consumers. This literature analysis of their policy history shows important differences in their evolution. Application of the Multiple Streams Framework can help in formulating possible explanations for the different developmental paths. These paths include: the degree of centralization or decentralization of the information system's organizational structure; the stability of the organizational mission; and the success of assessment strategies, federal budgetary support, and bias toward science in federal policy-making. These two government-supported databases served as models for a plethora of other databases. However, one was successful in acquiring funding from the outset, while the other continually suffered deficiencies in support. The importance of each to public welfare should have been obvious, but was not. 相似文献

Abstract The ERIC database is available in many free Internet versions, mainly from ERIC clearinghouses. Paying for access to ERIC through a commercial vendor is a decision that needs to be justified by all libraries with finite budgets. This case study attempts to determine the relative merits of the features and functionality of the various free versions of the ERIC database in comparison with one commercial version. Conclusions are shared about decisions reached at one academic library. The conclusion centers on whether libraries can forgo a commercial version of the ERIC database. 相似文献

When is ERIC Useful? A Background and Current Overview of the Education Resources Information Center
Kate Corby 《The Reference Librarian》2013,54(2):137-149
The Education Resources Information Center (ERIC) underwent substantial change during the 2004 contract cycle. Since it began in 1966, it has always been a highly respected and heavily used bibliographic resource, but some users are unaware of its current status due to the recent changes in its format and availability. This update highlights major developments and assesses the resulting ERIC product in light of the current education index marketplace. 相似文献
