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…

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…

This report on options for developing the University of California (UC) MELVYL online library system discusses the system in relationship to the current environment, including national and network information resources, electronic publishing, campus libraries, and changing user expectations; and places the growth of the MELVYL system in the…

The experiences of novice users (freshman students at Ohio University) searching OCLC's FIRSTSEARCH set of databases were studied. The 13 subjects were asked to complete a search on the FIRSTSEARCH databases; and data were collected through observations, administration of a questionnaire, and a thinking-aloud protocol. Data were analyzed to…

Computerized systems have dramatically altered the way that information can be organized, published, searched and retrieved. This paper: (1) examines the components of subject access in online systems; (2) identifies the potential for subject access enhancements, such as enriching the contents of the database and improving user-system interaction,…
