Investigated the effects of group size and exposure time in the use of a commercially prepared tutorial program or drill-and-practice software by 168 fifth and sixth graders. Found that exposure time was related to students' scores on posttests. Results suggested a need to examine allocated time in microcomputer learning situations. (LB)

Discusses the changing role of libraries as advances in information technology are made and describes projects that involve Digital Equipment Corporation. Highlights include changes in vendor products, services, and alliances; meeting user needs; statewide networks; Sonoma Internet Library Access Software; electronic libraries; open computing;…

The third in a series of 3 articles, a study of 30 students was conducted to test the effect of restructuring a unit on trigonometric identities around microcomputer activities based on the themes of educational undercurrents identified in Part II. Experimental-group students scored significantly higher relating trigonometric functions to their…

Describes an experiment that was conducted using a digital video course to determine the effects of multimedia interface capabilities on computer-assisted instruction, particularly on recall performance and attitude. Results are reported that indicate motion video is more effective than slides, and design guidelines are suggested. (34 references)…

Discusses reasons why libraries are being forced to seek new forms of information storage. A hypothetical scenario of user-initiated document delivery alternatives integrated with a search process used by a professor using the Harvard OnLine Library Information System is presented. Extensive notes elaborate on the process and the technology…

Investigates effect of computer-aided instruction (CAI) on acquisition of communication skills. Sketches a tutorial of the basic communication structure. Recommends confining CAI to cognitive learning because CAI cannot advance communication skills. Maintains that integrating CAI in social arrangements will allow the computer to remain an…

The purpose of this study was to train and empower computer teacher facilitators through enabling them to introduce technology to children, instruct peers in use of computers for early childhood education, and improve family literacy and computer literacy through parent education. Found significant differences and implications for empowered roles…

Data collected for the International Association for the Evaluation of Educational Achievement (1989) within U.S. secondary schools revealed that computer usage more than doubled from 1985. Discussed are the regular and systematic uses of computers in the classroom and laboratories, the types of software used, and the goals for teachers using…

Described is a weekly computer algebra laboratory course for Calculus I students during the 10-week spring semester, 1990, at Trinity University. Advice on the establishment and management of this type of laboratory including descriptions of student participation trends and student reactions is presented. (JJK)

N:4$2 N:4$N Reported are results of a Technical Education Research Centers (TERC) project describing telecommunication interactions between groups of students using the computer software unit "Connectany." Polygons are formed through repetitive "jumps" between points on a circle. Investigation questions and results are shared…

This study found that training teachers (n=5) to use prediscussion questioning techniques to integrate computer software into the reading instruction of high school students with mild disabilities did not result in significant differences in students' comprehension scores. Homogeneously grouped students (n=29) demonstrated greater achievement than…

Reviews new educational technology products, including a microcomputer-based tutoring system, laser barcode reader, video/data projectors, CD-ROM for notebook computers, a system to increase a printer's power, data cartridge storage shell, knowledge-based decision tool, video illustrator, interactive videodiscs, surge protectors, scanner system,…

This special section on local area networks includes three articles: (1) a description of migration at Joyner Library, East Carolina University (North Carolina) to a new network server; (2) a discussion of factors to consider for network planning in school libraries; and (3) a directory of companies supplying cable, hardware, software, and…

Describes four studies that explored how search experts and domain experts conducted searches in full-text, end-user search systems. Problem definition/expectation; query formulation; examination and extraction; reflection, stopping, and search monitoring; and system effects are examined for each study. (26 references) (EA)

Three commercial products for data acquisition with the Macintosh computer, known by the trade names of LabVIEW, Analog Connection WorkBench, and MacLab were reviewed and compared, on the basis of actual trials, for their suitability in physiological and biological teaching laboratories. Suggestions for using these software packages are provided.…
