Educational institutions and governing practices are increasingly augmented with digital database technologies that function as new kinds of policy instruments. This article surveys and maps the landscape of digital policy instrumentation in education and provides two detailed case studies of new digital data systems. The Learning Curve is a…

Because the relationship between computer use and achievement is still puzzling, there is a need to prepare and analyze good quality datasets on computer use and achievement. Such a dataset can be derived from TIMSS data. This paper describes how this dataset can be prepared. It also gives an example of how the dataset may be analyzed. The…

Models in Software Engineering are considered as abstract representations of software systems. Models highlight relevant details for a certain purpose, whereas irrelevant ones are hidden. Models are supposed to make system comprehension easier by reducing complexity. Therefore, models should play a key role in education, since they would ease the…

Summarizes the best known methods of using the signature file access method as a storage structure in information retrieval in nonbusiness applications of multimedia data. The relationships between application area, type of data, and signature file organization are emphasized. Results are summarized in a selection guide. (Contains 26 references.)…

This book provides guidelines for evaluating a variety of database types, including abstracting and indexing, directory, full-text, and page-image databases available in online and/or CD-ROM formats. The book discusses the purpose and techniques of comparing and evaluating the most important characteristics of textual databases, such as their…

The Comparative Database System (CDS) provides a means for coding and using data on U.S. and international postsecondary educational activity and behavior. CDS permits education-data users to obtain accurate and reliable comparative data on postsecondary education questions. This document contains a discussion of the development of CDS, a detailed…

Examines the use of various statistical techniques for generating domain-oriented multiword vocabulary terms for natural language database systems. Conclusions show the vocabulary clustering effect should be considered when making significance calculations and that a simple ratio of subject matter relative frequency to total sample relative…

This second report on a two-part study on the application of informetrics to information retrieval (IR) system design used models of database contents in a factorial simulation study at the University of Western Ontario. The study explored whether different file structures were better suited for different informetric environments. (32 references)…

This study evaluates two databases, "Historical Abstracts" and REESWeb, to determine their effectiveness in supporting academic social science research. While many performance evaluations gather quantitative data from isolated query and response transactions, this study is a qualitative evaluation of the databases in the context of…

A project studied use of state unemployment insurance (UI) wage-record data for Program Year 1986 to assess the effectiveness of Job Training Partnership Act (JTPA) programs. Eleven of 27 interested states were selected by ability to meet data requirements. These issues associated with the use of UI data as an assessment tool were explored:…
