The Unified Network of Informatics in Teacher Education (UNITE) is intended to establish a cooperative environment for exchanging ideas and computing resources among school administrators, teachers, interns (student teachers), and teacher educators who are separated by physical distances. A primary objective of the initial phase was to investigate…

This paper provides an overview of past research on training employees for computer-mediated work. Recent literature is reviewed and critically analyzed using a four-part framework of individual differences and skill acquisition: sociodemographic factors, abilities and motivation, task constraints, and the man-technology interface. Furthermore, a…

In order to build robust natural language processing systems that can detect and recover from miscommunication, the investigation of how people communicate and how they recover from problems in communication described in this artificial intelligence report focused on reference problems which a listener may have in determining what or whom a…

Formal educational environments often provide less support for learning than do the everyday environments available to young children. This paper considers the concept of idealized learning environments, defined as "Havens." Various components of Havens are discussed that may facilitate comprehension, especially in science instruction.…

This report for the period January 1, 1972 to June 30, l976 describes a program conducted to reach the following major objectives: (1) to develop, test, and operate a large geographically dispersed PLATO IV network; (2) to implement an educational program involving educational liaison, teacher/author training, curriculum planning, and materials…

The 45 papers in this collection are contributed, refereed papers submitted for publication in the proceedings of the 18th Annual Association for Educational Data Systems Convention. They cover educational applications of computers in the following areas: computer assisted instruction, computer managed instruction, instructional and learning…

The report summarizes the results of a number of studies which have been performed in an attempt to develop a technology for using human resources data as criteria in engineering design studies. Eight investigations conducted during the period 1966-1975 are briefly described. The results of the eight studies are integrated around six topics of:…

The potential use of computers to enhance individualized instruction in schools is too often neglected in both preservice and inservice teacher education. This report describes some materials developed and used to introduce teachers to computer applications in support of classroom teaching. The materials include some interactive computer-based…

Describes the development and evaluation of an interactive videodisc designed for Open University students in a physics course that explores the physical properties of water. The user interface is discussed; software is described; videodisc production is explained; and results of an evaluation of student attitudes from questionnaire responses is…

Summarizes three research studies on text and screen density variables in a computer based instruction (CBI) lesson. The first two studies investigated the effectiveness of low density text on lessons taught in print and CBI modes; the third study examined learner preferences for different screen densities. (43 references) (Author/LRW)

Describes a study of students at Purdue University that examined the roles of gender, right- versus left-handedness, and mouse experience in preferences concerning the placement of icon buttons within hypermedia user-interface designs. Response rate is examined, order of presentation is discussed, and further research is suggested. (11 references)…

Identifies problems that undergraduate searchers encountered in a search of the ERIC database on CD-ROM. Results of participant observation, questionnaires, and interviews are reported; a taxonomy of user problems is proposed that includes syntactic errors and semantic errors; and recommendations for menu selection systems, online help, and…

An interactive, computerized sound machine was designed, incorporating bar-code technology in the user interface. The system was used in a classroom of nine blind elementary level children to teach sound awareness, logic, metalinguistics, and technological literacy and was found to have pedagogical relevance. (Author/JDD)

This exploratory study of graduate students attempts to quantify some of the interactions that take place between learners and a computer-based instructional lesson teaching basic memory skills. Variables studied include age, undergraduate grade point average, sex, and standardized test scores. (Author/LRW)

Describes an interactive, cooperative-learning environment, "The Biology Sleuth." Characterizes students' interactions with this system, relates the underlying design concepts and principles, and presents a rationale for the system design. Describes a series of three formative evaluations, that were critical in the maturation of the system.…
