The computer packages of PLOTALL, SYMAP, SURFACE II, QUSMO, QUSMO2, QUCRS, and QUTAB are commercially available plotting programs that provide aids for visualizing spatial distributed data and concepts. The incremental drum and line printer plots communicate often vast and difficult-to-interpret tabular data with or without geographic coordinates.…

This presentation outlines guidelines for developing and implementing an introductory course in computer-aided drafting (CAD) that is geared toward secondary-level students. The first section of the paper, which deals with content identification and selection, includes lists of mechanical drawing and CAD competencies and a list of rationales for…

Describes the design of a microcomputer-based system at the University of Ottawa which provides teachers with the capabilities of computerized slides and transparencies. The slides are texts created with word processors which are presented to the class via a large screen video projector, and software provides regular overhead projector functions.…

Discusses the need to take into account the effects of arrested fractional crystallization in the petrographic classification of volcanic rocks containing plagioclase phenocrysts. Describes the development and use of a computer program to accomplish this task graphically. (TW)

Supporting evidence from both neurological research in brain hemisphere functions and comparisons of the use of symbols in Eastern and Western cultures are used to advance the position that the capability of graphics software for microcomputers to combine textual and visual elements makes them a powerful and revolutionary communications tool. (CLB)

Description of the field of robotics and its possible use in high school computational geometry classes emphasizes motion planning exercises and computer graphics displays. Eleven geometrical problems based on robotics are presented along with the correct solutions and explanations. (LRW)

Discusses the importance of the computer in the history of literacy and proposes that electronic technology will foster change in both the structure and symbolic character of writing. Writing as technology, the structure of electronic text, computer symbols, the spatial character of writing, and writing and speaking are considered. (EM)

During the first 12 weeks of an applied calculus course, two classes of college students studied calculus concepts using graphical and symbol-manipulation computer programs to perform routine manipulations. Three weeks were spent on skill development. Students showed better understanding of concepts and performed almost as well on routine skills.…

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)

Cites advances in x-ray diffraction, nuclear magnetic resonance, computer modeling, and display to guide the design and analysis of protein structures. Reviews recent advances in knowledge, synthesis techniques, and theory of proteins. (JM)

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)

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…

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)
