This paper lists the commands for three programs in Logo: Peppy and the Maze, Caterpillars and Butterflies, and the Robot Arm. (EW)

A new system of computer-assisted instruction (CAI), developed at Whitworth College, is proposed called PIRATS. It is said to have the following advantages: (1) it uses an author language; (2) it provides facility for branching and responses to unpredicted answers; (3) lesson text is prepared off-line; (4) pictures can be used to accompany the…

The Lister Hill National Center for Biomedical Communications has supported a program to develop a Plasma Terminal System for purposes of improving the effective delivery of computer based educational materials. This system, employing recent advances in microprocessing and storage technologies, will provide new alternatives for present users of…

This paper describes a system which operates on an independent basis as well as connected to communications network, e.g., PLATO and ASCII based communication systems. The system also has facilities for local production and use of PILOT lessons, for support of a generalized programming language (NSBASIC), and for development of graphic sequences.…

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)

Describes an experiment which linked the Canadian Videotex development, TELIDON, with the Canadian CAL system based on the course author/programming language NATAL. A bibliography of 14 references is provided. (CHC)

This discussion of the advantages and limitations of raster graphics systems points out that until recently, most computer graphics systems have been oriented toward the display of line drawings, continually refreshing the screen from a display list of vectors. Developments such as plasma panel displays and rapidly declining memory prices have now…

The fundamental problem for control languages is that they must be able to deal with the simultaneous actions of multiple objects. Accordingly, it is the basic premise of the HyperTechnic system that it is easier for children to view control problems in terms of relationships between multiple agents, rather than as one agent responding to a…

This paper, presented at a symposium on computer-based instructional systems, discusses innovations in the TICCIT computer-based instructional system. Specific issues addressed include innovations in the system's authoring languages, integration of videodisc technology, instructional management systems, creation of color computer graphics using a…

The scenario of instructional development presented makes a case for relying on recent refinements of the computer as a tool for giving form to human knowledge. The computer is described as having a high capability to form ideas into a variety of shapes, and vary those shapes to appeal to people's sense of abstraction. The history of the…

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…

This study was conducted to determine whether young children, given the experience of Logo programming, would acquire problem-solving skills and be able to transfer those skills to other areas. The study also investigated Logo's effectiveness in teaching certain fundamental geometric concepts to children who were supposedly not developmentally…

Turtle graphics is a popular vehicle for introducing children to computer programming. Children combine simple graphic commands to get a display screen cursor (called a turtle) to draw designs on the screen. The purpose of this study was to examine young children's abilities to function in a simple computer programming environment. Four- and…
