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.

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…

Research in human computer interaction and instructional design can provide insights into effective methods for training microcomputer users. Suggestions include utilizing error recognition and recovery, development of mental models, simplification of documentation, and using cognitive approaches that allow transfer of knowledge to new situations.…

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.

Provides an overview of the American Library Association (ALA) 1991 midwinter conference. Highlights include federal legislation, the organization of library support staff, fees for library services, library collection preservation policies, electronic access, access policy guidelines for academic libraries, reference staffing for electronic…

Discusses distance learning, describes the Open University in the United Kingdom, and describes the incorporation of home computing into computer courses at the Open University. Industrial training is discussed, a course using televised classes and one using video and printed materials are described, and future possibilities are suggested. (Three…

Discussion of navigation through virtual information environments focuses on the need for robust user models that take into account individual differences. Considers Pask's information processing styles and strategies; deep (transformational) and surface (reproductive) learning; field dependence/independence; divergent/convergent thinking;…

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.…

Researchers have suggested that up to 50 % of the effort in development of information systems is devoted to user interface development (Douglas, Tremaine, Leventhal, Wills, & Manaris, 2002; Myers & Rosson, 1992). Yet little study has been performed on the inclusion of important interface and human-computer interaction topics into a current…

Presents a classification scheme for generations of online catalogs; discusses current online technologies and identifies deficiencies; and discusses enhancements that will take online catalogs into the next generation. Such enhancements will include increased access to information through user-system dialogue, automatic search aids, subject…

Six papers dealing with decision support and knowledge based systems are presented. Five of the papers are concerned in some way with the use of artificial intelligence techniques in individual or group decision support. The sixth paper presents empirical results from the use of a group decision support system. (CLB)

This study examined an application of a human machine interface which relies on the use of optical bar codes incorporated in a computer-based module to teach radio production. The sequencing procedure used establishes the user rather than the computer as the locus of control for the mediated instruction. (Author/MBR)

In an experiment designed to dissociate the effects of instructional approach and system interface on learning in computer-based instruction, 18- to 30-year-old high school graduates with low mathematics ability were tested before and after completing three mathematics practice modules. Found that low ability students may not learn from computers…
