The design of an Intelligent Tutoring System (ITS) in a knowledge domain where expertise is modeled as a set of uncertain and incomplete beliefs that are justifiable and expressible in the form of a critical argument is outlined. Issues concerning knowledge communication in a tutorial interaction are discussed with reference to a cognitive model…

This report summarizes the results of a nationwide survey of teachers in grades 4 through 12 who are experienced and accomplished at integrating computers into their teaching. Of 1200 teachers who were sent the 16-page questionnaire, 608 returned completed surveys. The purpose of studying these teachers was to discover the ways in which they use…

The Computer Education Program, funded by the Municipal Assistance Corporation/Vocational Improvement Program (MAC/VIP), assists New York City high schools in promoting computer education and integrating the use of computers in subject area instruction. Project goals include providing assistance in the evaluation, purchase, and installation of…

Divided into three sections, this book presents a selection of papers arising from a conference that focused on the impact of recent technological advancements on the development and teaching of reading. An introduction by J. M. Ewing provides general insight on this topic. Identifying major concerns, the first section includes: "Reading and…

This master plan focuses attention on the roles computers will play in improving the quality of education over the next 5 years in the Maricopa Community College District. Following an executive summary and introductory material, definitions of instructional computing, computer infusion, and levels of software are presented along with assumptions…

Designed to investigate whether or not science teachers can positively influence student achievement in, and attitude toward, science, this study focused on a specific teaching strategy and utilization of a computer-based simulation. The software package used in the study was the simulation, Volcanoes, by Earthware Computer Services. The sample…

Designed to provide descriptions of computing activities in Florida's school districts, postsecondary institutions, and the State Department of Education (DOE), this report is organized into activities at four levels--K-12, community college, university, and DOE. Information gathered from a majority of Florida's 67 school districts is divided into…

The 52 papers in this volume, which represent recent research and applications in the field of computer-based instruction, are grouped under 10 general topic areas: (1) computer-based training; (2) elementary, secondary, junior college, and math education; (3) health; (4) home economics; (5) implementation; (6) mini-microcomputers; (7) PILOT; (8)…

A training procedure was developed to improve (or to encourage) the construction of a meaningful problem representation by mentally retarded and learning disabled children. Children are taught to use an external visual representation for arithmetic word problems, in which the meaning of the problem is reflected. The construction of this visual…

This document is intended to describe several software learning environments in an order that parallels a reasonable sequence of use by students. It also describes a planned an designed, but not yet implemented, extension of these environments from the discrete to the continuous case. Each of the implemented environments was developed in…

This paper discusses the overall design of the PIXIE Intelligent Tutoring System, and more specifically a series of recent enhancements. The original system has been implemented to involve three separate phases: the offline, or model generation phase; the online, or tutoring, phase; and the analysis phase. The offline phase, which is completed…

The effect of mode of computer-assisted instruction (CAI) and individual learning differences on the learning of science concepts was investigated. University elementary education majors learned about home energy use from either a computer simulation or a computer tutorial. Learning of science concepts was measured using achievement and…

The Exceptional Children and New Technology project sought to meet the instructional needs of physically handicapped, emotionally disturbed, learning disabled, and mentally handicapped children through the use of computer technology. The goals of the project were to test the instructional value of adaptive/assistive devices with exceptional…

The mathematical experiences of elementary students often focus on memorizing facts and rules as opposed to making sense of the subject and developing problem solving skills. Students spend large amounts of time processing, memorizing and sorting collections of data which are tasks well performed by computer technology. To correct this situation,…

Twin aims--to advance theory and to improve practice in science, mathematics, and computing education--guided the Educational Technology Center's (ETC) research from its inception in 1983. These aims led ETC to establish collaborative research groups in which people whose primary interest was classroom teaching and learning, and researchers…
