A study of microcomputer courseware reviews was carried out in order to discover which criteria they discuss, whether reviewers agree in their assessments, how evaluative the reviews are, and whether the reviewing policy of the journal influences the review. The content analysis instrument was a composite of criteria developed by organizations…

This study focused on the cognitive conflicts experienced by young children in using software programs that provided them with tools to create and/or combine individual graphic elements into larger structures. Six 5-year-old children, none with prior computer experience, were observed using three programs--Kids at Work, Picture Perfect, and…

Experiences in the development of educational software in the Netherlands have included the use of individual and team approaches, the determination of software content and how it should be presented, and the organization of the entire development process, from experimental programs to prototype to final product. Because educational software is a…

This guide discusses three critical steps in selecting microcomputer software and hardware: setting the context, software evaluation, and managing microcomputer use. Specific topics addressed include: (1) conducting an informal task analysis to determine how the potential user's time is spent; (2) identifying tasks amenable to computerization and…

This paper describes the use of video to provide a screenplay depiction of a proposed artificial intelligence software system. Advantages of such use are identified: (1) the video can be used to provide a clear conceptualization of the proposed system; (2) it can illustrate abstract technical concepts; (3) it can simulate the functions of the…

This study examines the Wheatley Cube as a measure of spatial/visualization ability. The Wheatley Cube is a computer managed task which requires the subject to visualize a three-dimensional workspace and to find an invisible dot located within this space. Thirty-three undergraduate students were administered four tests of spatial/imaginal ability…

A state-wide microcomputer software program and support system for local education agency (LEA) reporting of Chapter 1 fiscal and evaluation information was developed. The microcomputer budget application for West Virginia was developed by the Technical Assistance Center at RMC Corporation. The program is intended for use by the Chapter 1 staff of…

This paper discusses a model of information storage and retrieval, the k-d tree (Bentley, 1975), a binary, hierarchical tree with multiple associate terms, which has been explored in computer research, and it is suggested that this model could be useful for describing human cognition. Included are two models of human long-term memory--networks and…

Describes the use of ALSCAL, a computer program for multidimensional scaling, to map enrollment in 49 electives at Drexel University's College of Information Studies during two time periods. The results for this department are presented, and the explanatory power of this evaluation technique for any curriculum is discussed. (6 references) (CLB)

For six weeks, pupils in grades two, three, and four used either flash cards or a microcomputer program to practice basic subtraction and division facts. Equivalent learning resulted. (MNS)

Suggests new method of external distribution called tree partitioning that involves use of binary tree to split incoming file into successively smaller partitions for internal sorting. Number of disc accesses during a tree-partitioning sort were calculated in simulation using files extracted from British National Bibliography catalog files. (19…

Presents a formal model for specification of logical requirements of computer-based information systems that incorporates structural and dynamic aspects based on two separate models: the Logical Information Processing Structure and the Logical Information Processing Network. The model's role in systems development is discussed. (MBR)

Discusses current use of psychological theory in software science and reviews recent developments in cognitive psychology relevant to programing (human information processing, expert-novice differences). Critique of Maurice Halstead's model of cognitive aspects of programing and a structured data flow perspective (control flow and data flow…

Using portable microcomputers, three applications programs were developed and implemented to collect, store, transmit, and analyze teacher/student observational data. The three applications involved: analyzing teaching behaviors of trainees in field-site placements, using microcomputers to educate mildly handicapped high-school students, and using…

Eight subjects participated in a comparison of the multipeak (MPEAK) and spectral peak (SPEAK) speech coding strategies of the Nucleus 22-channel cochlear implant system. Overall, speech recognition performance was significantly higher with the SPEAK strategy than with the MPEAK strategy on all speech tests. (Author)
