Discussion of speech recognition technology and its use in computer-assisted instruction focuses on prototype systems designed for medical education. Commercial speech recognition systems are described, hardware and software requirements are examined, and the use of a speech recognition system to streamline an existing user interface is discussed.…

This framework sets forth detailed proposals that are crucial to eliminating the epidemic of childhood lead poisoning in the United States. Private housing units can and must be made lead-safe, and this framework is designed to achieve that goal through specific requirements for property owners, a workable schedule, and mechanisms that reinforce…

This discussion of the design of user-initiated help systems in computers focuses on the information that users actively seek to help them with their tasks, with emphasis on how to help users ask the questions that will bridge the gap between the initial internal (mental) form of the query and their information need as expressed by the system.…

This four-section paper begins with a brief description of videotex and the paths its development has followed during its short lifespan. The second section examines how videotex systems should present and display information, and how such information should be internally organized so that it is maximally useful for the reader/user. The analysis,…

A group of American and Japanese psychologists, anthropologists, linguists, and computer scientists gathered at the University of California, San Diego, to exchange ideas on models of joint problem solving and their special relevance to the design and implementation of computer-based systems of instruction. Much of the discussion focused on…

Three discussion papers about the Open University's correspondence texts consider (1) the role of a transformer, i.e., any person working in communication media who is responsible for the effectiveness of his/her decisions; (2) factors involved in the design of Open University texts, including their use as a resource for a range of different…

Designed to address the management and use of computer software in education and training, this paper explores both good and poor software design, calling for improvements in the quality of educational software by attending to design considerations that are based on general principles of learning rather than specific educational objectives. This…

This working paper, which reviews the experimental literature on learning skills to provide background information to the staff of the Skills Essential to Learning Television Project (a multi-level series of video and print resources for classroom use), covers four areas: study skills, instructional development and design, cognitive psychology,…

This essay focuses on use of the Library of Congress Subject Headings system in online catalogs for the retrieval of information by subject. Among the topics addressed are differences among catalog forms (card, microform, and computer); user interface with different forms of catalog; the types of subject indexes employed in present online…

Hypotheses about the potential educational benefits of interactive video systems (IVS) are described. IVS, if properly designed and applied, has the potential to increase learning, encourage student-initiated learning, and provide a context for what has been learned. A call for research is made. (JL)

Defines the term "simulation"; discusses role of instructional simulations, particularly computer-based; describes what constitutes an effective simulation and its appropriate use; and reviews several specific examples of computer simulations, emphasizing nature and quality of student interaction with the model. (MBR)

Discussion of problems and mistakes made in library facility planning highlights overemphasis of dramatic architectural elements; communications between architects and librarians; who is in charge of planning process; lighting (effect of library shelving, appropriate location of light switches); setting a schedule; furniture and equipment; and the…

Defines the functions of windows that are used as visual display techniques in computer software systems, reviews research on the effectiveness of window environments, discusses knowledge structures, and presents principles for designing windowed environments based on research findings and individual differences and screen design research. (10…

In 1990, Americans with Disabilities Act (ADA) was passed, and schools must now comply with requirements to remove any physical barriers inhibiting public access to educational facilities. Includes what the "disabled" category covers; other groups and programs that should be accessed for help in implementing ADA goals; and a four-step…

Addresses research results and controversies concerning the ergonomic design of computer work stations ranging from the traditional concerns with anthropometric fashions, work posture, and visual performance to the recent considerations about human information processing capacities and awareness of problem-solving strategies. (eight references)…
