Argues that students should have dynamic perceptual experience with the concepts central to circular functions. Includes a computer program, designed for Apple II, to provide such experience. (PK)

Logo creator Seymour Papert discusses ways Logo can be improved to accommodate different learning styles and strengthen word processing and list processing capabilities. In an interview, Papert discusses computers' influences on learning, Logo's underlying concepts, teacher use of Logo, Logo's discovery learning approach, and development of Logo…

Describes the design of a database interface for infrequent users of computers which consists of a graphical display of a model of a database and a natural language query language. This interface was designed for and tested with physicians at the University of Texas Health Science Center in Dallas. (LRW)

Discusses evaluation criteria for selecting authoring tools, including system complexity and language, cost, copy protection, ease of learning and use, graphics, sound, and peripheral interfacing capabilities, support documentation, overall performance, tutorials, instructional design and management features, and product support. A…

Recounts experiences of the Carbon Dioxide Information Center, a technical information analysis center at the Oak Ridge National Laboratory, which has utilized a microcomputer for exchange of automated bibliographic references. Procedures and problems in adding microcomputer information to mainframe databases are noted and other microcomputer…

Discusses three trends in computer-oriented chemistry instruction: (1) availability of interfaces to integrate computers with experiments; (2) impact of the development of higher resolution graphics and greater memory capacity; and (3) role of videodisc technology on computer assisted instruction. Includes program listings for auto-titration and…

Describes how color graphics are built up on microcomputer displays and how a range of colors can be produced. Discusses the logic of color formation, noting that adding/subtracting color can be conveniently demonstrated. Color generating techniques in physics (resistor color coding and continuous spectrum production) are given with program…

Described is a project that involved undergraduate geography students in developing a model of the accessibility of the pre-school population in Cardiff (England) to child care clinics. Programing skills were acquired through spatial modelling. Networks of mini- and micro-computers were used. (Author/RM)

Focuses on the multiple design issues involved in creating successful menu selection systems: semantic organization, response time, display rates, shortcuts for frequent users, titles, phrasing of menu items, graphic layout, and selection mechanisms. Pop-up and embedded menus, experimental results, and design guidelines are also covered.…

Provides instructor's guide and participant materials for a workshop introducing LOGO. It includes background information on LOGO, introduction to graphics and commands, its utilization to teach geometry, defining and editing procedures, subprocedures, differences between linear chaining and block style programing, and using LOGO to print and…

Discusses computer graphics and computer-aided design in the freshman engineering program at the University of Texas at Austin. Procedure uses interactive modules that do not require any programing skills. An annotated test of modules used and suggested approaches that might be useful at other schools are included. (BC)

Outlines basic choices available in on-screen windowing systems which create separate areas or boxes on microcomputer display screens to simplify control of traditional computer applications. Systems described include Visicorp's Visi On, Microsoft Windows, Digital Research's Concurrent DOS, Quarterdeck's DesQ, Structured Systems' Window Master,…

Five computer-oriented classroom activities are suggested. They include: Logo programming to help students develop estimation, logic and spatial skills; creating flow charts; inputting data; making snowflakes using Logo; and developing and using a database management program. (JN)

Describes the programs and modifications needed to do word processing using foreign language characters. One such program, Screenwriter, uses soft character sets -- character sets which can be designed by the program user. This program has a word processing power combined with a foreign language capability that would allow any person to work with…
