Online learning has attracted a large number of participants and is increasingly becoming very popular. However, the completion rates for online learning are notoriously low. Further, unlike traditional education systems, teachers, if any, are unable to comprehensively evaluate the learning gain of each student through the online learning…

In online educational systems we can easily collect and analyze extensive data about student learning. Current practice, however, focuses only on some aspects of these data, particularly on correctness of students answers. When a student answers incorrectly, the submitted wrong answer can give us valuable information. We provide an overview of…

Today many data warehousing systems are data rich, but information poor. Extracting useful information from an ocean of data to support administrative, policy, and instructional decisions becomes a major challenge to both database designers and measurement specialists. This paper focuses on the development of a data processing system that…

Describes a novel design of a Table Browser for casual users of statistical data. Focuses on the overall system architecture and the user interface. Describes the prototype interface and presents results of experiments testing the efficacy of the multi-threaded data flow. (AEF)

Fifteen papers on computer centers and data processing management presented at the Association for Educational Data Systems (AEDS) 1976 convention are included in this document. The first two papers review the recent controversy for proposed licensing of data processors, and they are followed by a description of the Institute for Certification of…

The Vocational Education Data System (VEDS) data base was created as a result of the Vocational Education Amendments of 1976. VEDS statistics were to be collected in the form of state-aggregate data (that is, state-level data is submitted by each state, based upon records and data collected by the state for this and other purposes); and VEDS data,…

A syntax methodology provides a descriptive mechanism to enable machine readable storage and retrieval of numeric data contained in bibliographic documents. The body of this paper treats the nature of "the syntax,""the data element," and the language by which this syntax is expressed. A discussion of the methodology illustrates…

Examines the relationships between purchases of optical data disk products, publishers, and software suppliers. The discussion covers current pricing strategies for optical data disk software and information products, and possible future developments in marketing and pricing. (CLB)

Computer-mediated communication (CMC) is used in different contexts and uses different tools, such as those of computer conferencing, e-mail, and groupware. This article introduces the use of Formal Concept Analysis (FCA) as a methodology to visualize the data in CMC. FCA, which is based on a mathematical lattice theory, offers visual maps…

This report describes the composition and operation of the library of the Gray Freshwater Biological Institute at the University of Minnesota, a non-traditional information service which provides information to the institute by combining the use of three bibliographic databases with current awareness services, OCLC, MINITEX, and author reprint…

Discusses reasons for selecting ERIC with the Dialog OnDisc software for training information professionals in online searching at the University of California, Berkeley, and analyzes some of the features of the CD-ROM software. Pros and cons of online and OnDisc access are summarized, and three references are listed. (Author/MES)

This study examines (1) subject content, (2) file size, (3) types of documents indexed, (4) range of years spanned, and (5) level of indexing and abstracting in five databases which collectively provide extensive coverage of the forestry and forest products industries: AGRICOLA, CAB ABSTRACTS, FOREST PRODUCTS (AIDS), PAPERCHEM, and PIRA. The…

Summarizing the methods currently being employed at the Ohio College Library Center (OCLC) for user interaction analysis, this study presents suggestions and provides examples for the use of audit trail data available from most online interactive systems. The sample data used in the analysis are from the OCLC online system used for cataloging,…

This paper describes the IBM 1500 Instructional System which is used for computer assisted instruction (CAI), research, and demonstration at the University of Alberta. The system automatically stores a performance record of each student's responses to instructional programs, and a number of CAI support programs are accessible to perform various…

Aspects of Data Fusion (DF) for information retrieval are explored. Based on a geometrical model of DF, it is shown that in the ideal case, performance of DF for a pair of information retrieval schemes may be approximated by a quadratic polynomial. Compares counter-intuitive cases of DF with cases that behave according to the geometric model. (AEF)
