This report presents the results of RAND research conducted at the U.S. Army Signal Center, Fort Gordon, Georgia, to evaluate the effectiveness of an interactive videodisc (IVD) system used to facilitate training in a variety of military occupational specialities. The objectives of the study were to: (1) develop a methodology for assessing the…

This issue of the journal contains abstracts and critical comments for 13 published reports of research in mathematics education. Topics include: (1) effects of mathematics anxiety on preservice elementary teachers; (2) visualizing rectangular solids; (3) computer simulations and abstract thinking; (4) the association of foldout shapes with…

Two classroom studies, one conducted in the spring of 1985 and the second in the spring of 1986, showed that many high school students do not differentiate between heat and temperature; instead, they have a single concept that contains some of the features of heat and some of the features of temperature. Because the distinction between these two…

This article is a review of the impact upon science learning of classroom and laboratory uses of computers in grades K-16 as revealed by published, peer-reviewed research from 1988-95. Highlights include problems with media-comparison studies, computer-assisted instruction, computer simulations, microcomputer-based laboratories, interactive video,…

Describes a computer simulation called ICCARUS (Intelligent Command and Control, Acquisition and Review Using Simulation) that was developed for training fire officers in the United Kingdom. The integration of microcomputer-based software, videodisks, and audio material on compact disks into the simulation is described; and results of an…

This study examines the effect of the "Technical Troubleshooting Tutor," a computer-coached training program, on aircraft electrical system troubleshooting. Performance ability differences between control groups are noted, and troubleshooting models and flow diagram examples are included. The study demonstrates the possibilities for…

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)…

Describes study that investigated teachers' criteria for the use of courseware packages in Dutch junior high school physics classes. The development of a courseware evaluation instrument is described; drill and practice, simulation, and tutorial courseware packages are evaluated; motivating elements are considered; and implications for the design…

Information and Communications Technology (ICT) plays a dominant role in enhancing teaching and learning. Similar advances have been made in the use of multimedia in the classroom. These advances are coupled with newer developmental tools and techniques. This paper examines the design and development of a simulation on water conservation. Science…

In this paper we argue that the use of audit trail data for research and evaluation purposes has attracted scepticism due to real and perceived difficulties associated with the data's interpretation. We suggest that educational technology researchers and evaluators need to better understand how audit trail data can be processed and analysed…

The goal of the research reported here was to examine how teachers perceived their role as coach, as well as how they actually interacted with students in a computer simulation environment. Simulations like "The Chelsea Bank" significantly impact the role of the teacher in the learning environment. The learner is placed in the role of…

Instructional feedback given to the learners during computer simulation sessions may be greatly improved by integrating educational computer simulation programs with hypermedia-based computer-assisted learning (CAL) materials. A prototype of a learning environment of this type called BRINE PURIFICATION was developed for use in corporate training…

From 1960 to 1980, school enrollment and educational expenditures in developing countries experienced significant expansion. By the late 1980s, however, this trend had slowed. This report examines the impact of education upon welfare and productivity. A unified global data set is used to address the question from a macroeconomic, gender-specific,…

The purpose of the study was to determine the effectiveness of a HyperCard simulation upon student's concepts, opinions, and option-rankings on solid waste management, and to investigate what cognitive activities of the students were involved in the decision-making processes. One hundred eighth-grade students in Taiwan participated in this…

Chapter One of the Education Consolidation and Improvement Act (ECIA) distributes compensatory education grants on the basis of a formula that considers population and cost factors for each of the nation's 3,128 counties. The focus of this report is the effectiveness of that formula in meeting the stated purpose of the legislation to provide aid…
