Describes the general methodology of time and motion studies and reports the results of a study which used this methodology to compare digitization of images in a microcomputer environment with storage of images on microforms. (CLB)

Reviews the current status of satellite remote sensing data, including problems with efficient storage and rapid retrieval of the data, and appropriate computer graphics to process images. Areas of research concerned with overcoming these problems are described. (16 references) (CLB)

Presents a system model for transmission of input data that is coming from terminals of users in a limited user resource-sharing environment. Performance of a mini/microcomputer receiving mixture of picture-phone terminal data is analyzed with constant service times, synchronous transmission, and single-server interruptions through first-order…

Description of new applications of digital optical disc storage technologies focuses on CD-ROM (Compact Disc--Read Only Memory); CD-I (Compact Disc--Interactive); and DV-I (Digital Video--Interactive). Features of each technology are described in the context of instructional design and educational technology, and the role of educational research…

Part 1 presents the chemistry, physics, and engineering technology associated with magnetic and optical disks. This part explores the subjects of archiving, security, validation and certification, and protection. Questions and issues are raised in each of the areas that both users and vendors should be aware. (JN)

Examines the vocabulary and chemistry of magnetic- and optical-disk storage technologies as well as their applications to the analytical laboratory. This information will allow chemists to select the proper disk systems for their laboratories and to evaluate vendors' claims. (JN)

A brief, non-technical synopsis of computerized data tape files available from the library of survey data collected over the last 20 years by the U.S. Department of Education Office of Educational Research and Improvement's Center for Education Statistics is provided in this directory. The available data files are listed in the following broad…

Presents a four-stage hypothesis of information systems development based on computational capability, storage capability, communications capability, and effective voice input. Moore's Law and Mooers' Law are explained, the interface between the system and the user is discussed, and projections for the future are suggested. (21 references)…

This article describes a number of problems every educational measurement specialist should be prepared to confront before using microcomputers to support test-related activities, including problems with hardware, with software, and with implementing a system. It concludes with a checklist for planning a microcomputer application. (BW)

Describes software for displaying documents on computer graphics screens which provide the opportunity for interactive user interfaces. Based on a software system called Guide, this new approach relies on advances in hardware, such as the CD ROM, and can be used in the front end of a document retrieval system. (Author/LRW)

This paper synthesizes some of the many ideas and issues pertaining to research on the development of writing skills, and on creating new technologies for writing. Such technologies include computer-based production tools, videodiscs, and other mass storage technologies with potential for knowledge storing and structuring. The discussion also…

This document contains the codebooks and data record layouts for the 1985-86 Public-Use Data Tapes, Version 1.0. The Public-Use data tapes are created by the National Assessment of Educational Progress (NAEP) to provide outside researchers access to NAEP data. This book provides coded data collected on and from third graders and 9-year-olds via…

This discussion of the use of images in learning processes focuses on recent developments in optical storage disc technology, particularly compact disc read-only (CD-ROM) and optical video discs. Interactive video systems and user interfaces are described, and applications in education and industry in the United Kingdom are reviewed. (Author/LRW)

This document is the users' guide for Version 3.1 of the Public-Use data tapes compiled by the National Assessment of Educational Progress (NAEP), 1983-84. The Public-Use tapes are produced to allow outside researchers access to the NAEP data. The tapes accompanying this guide contain data assessing student achievement in reading and writing at…
