Presents a detailed analysis of courseware design activities based upon the use of conceptual data models for content elaboration. Highlights include discussions of computerized training systems, authoring languages and authoring systems, and the distinction between processing and data. (Author/LRW)

This project was designed to develop techniques for adding low-cost speech synthesis to educational software. Four tasks were identified for the study: (1) select a microcomputer with a built-in analog-to-digital converter that is currently being used in educational environments; (2) determine the feasibility of implementing expansion and playback…

This project report details the design of an interactive authoring system for the development of computer assisted instructional (CAI) software. This system is possible because the development of more powerful computing and software systems has facilitated authoring systems which allow the development of courseware in an interactive mode and…

Designed to test the premise that the production system for courseware has a strong impact on the quality of the courseware developed, a survey of 14 U.S. institutions of higher education was conducted in 1986 to investigate the production systems used by these schools. Many of the questions used and the list of institutions surveyed were…

This study investigated the effectiveness of LOGO's turtle graphics in both providing a model of systematic thought and in teaching simple geometry to young children in the second grade. The treatment given to 25 second grade students in the experimental group consisted of programming with LOGO's turtle graphics using four Apple II+…

Examines the impact of computers on Chilean education. Topics discussed include the Chilean educational system; the integration of computers in private schools; leadership; and results of a survey that characterized the use of computers in 1,604 schools, including socioeconomic levels of students, types of computers and software, and computer…

Introduces some general concepts and techniques of artificial intelligence (natural language interfaces, expert systems, knowledge bases and knowledge representation, heuristics, user-interface metaphors, and object-based environments) and investigates ways these techniques might be applied to analysis, design, development, implementation, and…

This survey of authoring languages that are used in computer-assisted instruction (CAI) highlights recent developments in Macintosh authoring languages and discusses their use in courseware development. CAI effectiveness is defined, advantages and disadvantages of CAI are described, and future research needs are suggested. (27 references) (LRW)

The first study investigates the validity of the Preschool Language Assessment Instrument as a diagnostic tool for differenciating the ability of language impaired preschoolers to use language to communicate complex ideas. The second study evaluates the relative effectiveness of two software environments that were expected to enhance children's…

Describes 12 constraints imposed by culture on educational software portability. Nielsen's seven-level virtual protocol model of human-computer interaction is discussed as a framework for considering the constraints, a hypothetical example of adapting software for Mexico is included, and suggestions for overcoming constraints and making software…

Presents results of a 1991 national survey conducted in The Netherlands that investigated the use of computer-assisted learning (CAL) in higher education. Topics addressed include academic disciplines using CAL; types of CAL, including drills, tutorials, and simulations; level of learner control; authoring languages and programing languages; and…

Describes a study that examined problem-solving strategies selected by African-American preschool students with differing cognitive styles using LOGO computer software. Highlights include spatial development, minority performance and cross-cultural differences in cognitive style, and differences in field-dependent/field-independent children in…

This study of 24 third-grade students learning Logo had 3 major research goals: (1) to compare the effects of learner control with those of program control on students' metacognition, knowledge acquisition, and knowledge application, with total subjects; (2) to extend the comparison between learner control and program control by classifying the…
