This paper explains the design of a graphics-based virtual environment for instructing computer hardware concepts to students, especially those at the beginner level. Photorealistic visualizations and simulations are designed and programmed with interactive features allowing students to practice, explore, and test themselves on computer hardware…

Three Dimensional or 3D virtual reality has become increasingly popular in many areas, especially in building a digital campus. This paper introduces a virtual campus, which is based on a 3D model of The Tourism and Culture College of Yunnan University (TCYU). Production of the virtual campus was aided by Human Factor and Ergonomics (HF&E), an…

(Purpose) The purpose of this paper was to examine the issues associated with bringing new technology into the classroom, in particular, the vocational/technical classroom. (Methodology) A new Haas 5 axis vertical Computer Numerical Control machining center was purchased to update the CNC machining curriculum at a community college and the process…

Ray tracing is a method that allows the creation of photo-realistic images on a computer. This article describes a shareware ray tracing program called PovRay and includes some ideas on how PovRay can be used in teaching and in 3-D geometry, physics, and other high school and university subjects.

Argues that current approaches to computer graphing practices are ill suited to meet the complex needs of real users. Offers an overview of work in two major areas of graphing theory and research: the sociology of science and the educational research of mathematics and scientific students. Suggests what technical communicators can do to improve…

There is a lot of educational software on the market, but little of it can be said to be revolutionary. Despite all the talk about education and computers, the educational software revolution has yet to begin. All educational software can be placed in categories of games (edutainment), simulations, reference software, and tutorials. Choosing…

A procedure for using MEL2 (Version 2.0 of Microcomputer Experimental Laboratory) and FontWINDOW to present special characters and symbols in computer-controlled reaction time experiments is described. The procedure permits more convenience and flexibility than in tachistocopic and projection techniques. FontWINDOW allows researchers to design…

Argues that technical communicators should have a working definition of icons, know when to use them, and understand some of the problems inherent in icon design. Recommends using a workable icon classification system and adhering to some practical design guidelines. (SR)

This study investigated the usefulness of the many-facet Rasch model (MFRM) in evaluating the quality of performance related to PowerPoint presentations in higher education. The Rasch Model utilizes item response theory stating that the probability of a correct response to a test item/task depends largely on a single parameter, the ability of the…

Reviews for three software packages are given. Those packages are: Linear Algebra Computer Companion; Probability and Statistics Demonstrations and Tutorials; and Math Utilities: CURVES, SURFS, AND DIFFS. (PK)

A brief package of subroutines (which can be typed in 15 minutes) enables a standard Apple II Plus, IIc, or IIe microcomputer to simulate a pen-plotter. Techniques for using this package in introductory engineering graphics courses are described. A sample program (which draws an oblique line) containing the subroutines is included. (Author/JN)

Suggested are features which should be considered before selecting a specific interactive graphics package. Features that allow for accurate estimates of roots of functions and solutions to systems of equations are illustrated. Six graphics packages are compared including display, tabular options, misleading graphics, printing options, functions…

Previous work focused on use of computer graphics in teaching thermodynamic phase equilibria for classes I and II. Extends this work to include the considerably more non-ideal phase behavior shown by classes III, IV, and V. Student and instructor response has been overwhelmingly positive about the approach. (JN)

Reviews three computer software programs: (1) "Discovery! Experiences with Scientific Reasoning"--problem solving for grades 4-12 (Apple II); (2) "Organic Stereochemistry"--a tutorial for organic chemistry for advanced secondary/college level (Apple II); and (3) "SHOW PARTNER (2.01)"--a graphics utility tool for…

Advances in World Wide Web design software, photo compact disk images, print-screening processes, and four- and six-color printing can make the work of campus publications easier, cheaper, and more attractive, but also have potential pitfalls. A preview of the latest innovations, with advantages and disadvantages noted, is offered here. (MSE)
