Discusses structural components of databases that require data-mining algorithms and describes the SUBDUE system that is designed to discover knowledge in structural databases. Analyses the ability of SUBDUE to scale to large databases and describes parallel and distributed implementations to investigate methods for improving the scalability of…

Based on a database of lesson extracts, this article attempts to characterize task-based interaction in the second-language classroom as a variety, discusses its pedagogical and interactional advantages and disadvantages, and considers what kinds of learning it might be promoting. (Author/VWL)

Discusses evidence-based medicine (EBM) and the need for systematic use of databases like MEDLINE with more sophisticated search strategies to optimize the retrieval of relevant papers. Describes an empirical study of hospital libraries that examined requests for information and search strategies using both structured and unstructured forms.…

This study examined the quality of medical students' confidence estimates in answering questions in bacteriology based on personal knowledge alone and what they retrieved from a factual database in microbiology, in order to determine whether medical students can recognize when an information need has been fulfilled and when it has not. (Author/LRW)

Discusses indexing in large text databases, approximate text searching, and space-time tradeoffs for indexed text searching. Studies the space overhead and retrieval times as functions of the text block size, concludes that an index can be sublinear in space overhead and query time, and applies the analysis to the Web. (Author/LRW)

Describes a database of information made available by the North Central Association Commission on Schools to assist schools with the tasks involved in the school improvement process. Discusses how to use this expert database. Provides suggestions for its use and an outline of 54 target areas. (VWC)

Indexing is the preprocessing of information to enable its retrieval, ranging from classification-based (precoordinate) to keyword searching (postcoordinate) approaches. This article describes a framework for modelling information retrieval systems in terms of sets of objects, relationships, and functions and discusses the application of indexing…

Review of research using data from five British national demographic surveys showed that secondary analyses occurred less often in education; such analyses focused on the effect of educational qualifications on employment; and some data remain relatively unexploited. (SK)

Sailor, Maryland's public information network, has become a national model for public libraries and states planning telecommunications networks and library systems integration. This article summarizes the design and implementation of the network's Internet resource collection development, highlighting the database committee, editorial board,…

Studied the reliability and accuracy of data from Statistics Sweden's Level of Living Surveys (register data) on the return on schooling using a sample of 2,914 adults. Findings show that this register data does not show some partial secondary and postsecondary studies that did not lead to degrees, and that there are difference in annual and…

Gives examples of how research can inform practice in correctional education by building theory and providing evidence of impact. Describes information sources: National Center for the Study of Adult Learning and Literacy, National Institute for Literacy, ERIC Clearinghouse on Adult, Career, and Vocational Education, and National Center for…

Explores the use of language corpora, focusing on the use of corpora in the classroom by students rather than as a background resource for teachers and materials designers. (Author/VWL)

Presents a strategic evaluation of the global multimedia scenario, considering both stand-alone workstations and distributed multimedia in the worldwide interactive network, including educational databases on the Internet. Discusses 50 technological, market, environmental, and regulatory factors and estimates their impacts on each other using WISE…

Describes how an introductory course in database management is enriched using the Internet and how students encounter problems with sociotechnical systems. Concludes with observations concerning conditions that must be in place for Internet-augmented systems. (DDR)

Outlines the basic database structure that should be in place in library automation systems. Suggests that any library automation system that includes a catalog should be using a database engine that uses the MARC record structure at its basic structure for record storage. Describes the elements of MARC 21 formats--the new standards for the…
