This report describes an experimental system for drawing simple pictures on a computer graphics terminal using natural language input. The system is capable of drawing lines, points, and circles on command from the user, as well as answering questions about system capabilities and objects on the screen. Erasures are permitted and language input…

This report provides a detailed description of Chips, an interactive tool for developing software employing graphical/computer interfaces on Xerox Lisp machines. It is noted that Chips, which is implemented as a collection of customizable classes, provides the programmer with a rich graphical interface for the creation of rich graphical…

Describes the use of programs written in BASIC and graphics facilities of microcomputers to make students aware of the assumptions of statistical models in linear regression and the design of experiments. Two references are cited. (CHC)

Discusses ways of providing graphic support in computer-based learning environments, outlines a simple case study involving a situation requiring graphic support, and describes several author language/systems that contain facilities to support the use of graphics. (MBR)

A 10-week project conducted with 12 gifted 4th and 5th grade students (10 boys and 2 girls) examined the effectiveness of the Logo computer programming language as a tool for helping students understand some basic principles of physics. Three assumptions were tested: (1) motivated elementary school students can learn both turtle graphics and word…

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…

This article examines naive conceptions of spatial reference that children bring to Logo programing language learning. Students from Grades 4, 5, 6, and 8 were introduced to six Logo commands, and then were tested on predicting the output for instances of each of the commands. (Author/LMO)

Described is an investigation into how the use of LOGO programing language affects children's basic knowledge of an angle. Findings indicate that children make erroneous adjustments to their conceptual knowledge of angle to accommodate the results of acquired procedural interaction with the computer. (Author/CW)

Summaries of research performed by the Information Sciences Institute at the University of Southern California for the U.S. Department of Defense Advanced Research Projects Agency in 17 areas are provided in this report: (1) Common LISP framework, an exportable version of the Formalized Software Development (FSD) testbed; (2) Explainable Expert…

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+…

Describes a study conducted with six pupils using Apple II Plus microcomputers and LOGO to determine whether five year olds can perform simple computer programing. This report describes the introductory educational games and activities, the pre- and posttests, some general findings, and possible implications for the teaching of problem-solving…

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)

This manual provides documentation for the design, construction, and operation of an interactive electronics training panel developed for a computer assisted performance training carrel. The panel is a plug-in module designed to simulate electronic circuitry and a PMS-6 multimeter as required for a troubleshooting fundamentals lesson in an Air…

Described is a short program for teaching and learning about geometric transformations. The integration of geometry problem solving and BASIC programing is discussed. Applications of computer graphics are illustrated. (CW)

This investigation of the potential of a Logo environment to develop visual literacy skills in elementary school students focused on the recognition of Escher-type geometric constructions by second and sixth grade students. Four research questions were addressed: (1) whether students can use higher-order and creative thinking skills in using…
