Because of the lack of error-free, on-task performance by young children, cognitive modeling has not generally been considered an appropriate technique for characterizing computer use by young children. It is argued that cognitive modeling can be a useful strategy for organizing data on children's performance when the domain being studied is…

This paper follows the evaluation of a system of student performance analyses programs which has advanced from a crude manual system to an easy to use, on-line, interactive system. Recently, emphasis has focused upon the development of a system which requires little computer expertise on the part of the author to obtain a concise, easy to read…

This study explored the effectiveness of "high" user-friendly instructional text editors versus "low" user-friendly editors in teaching word processing to adult females. Whether subjects having higher positive attitudinal scores toward technology would perform better with computerized instructional materials as facilitators for…

The work of a three-year series of experimental studies of human cognition is summarized in this report. Proglem solving and learning in man-machine interaction was investigated, as well as relevant variables and processes. The work included four separate projects: (1) computer-aided problem solving, (2) computer-aided instruction techniques, (3)…
