A proposition that 3-D CAD provides an array of unambiguous solutions to engineering problems is illustrated. This proposition assumes that engineering problems are conceived in parallel processing mode while they are solved in sequential processing mode. Circle construction analysis, parallel equidistant planes, and solid modeling are discussed.…

An approach to reduce the barrier between two-dimensional computer-aided drafting and three-dimensional constructive solids modeling is graphically illustrated. This process, or some derivative, encompasses a significant portion of the future direction for engineering graphics education. (KR)

Described is a pilot course which includes a designed set of exercises to instruct students in procedures for creating solid models. A detailed description and analysis of students' various approaches used in completing a final design project are included. (KR)

Describes an introductory graphics course developed to expose undergraduates in the use of computer-based graphics as both a problem-solving and communication tool within engineering, the sciences, and other technical areas. Discusses course strategy, classroom setup, course content, and various software packages utilized in the course. (Author/KR)

Examines mathematics problem solving in a computer software environment using graphical representations of the results of simulations with adolescent students. Discusses the strengths and limitations of inferring goals and plans, the use of verbal protocols, and ways for computer-based learning environments to scaffold acquisition of domain…

Graphical plans for construction of machinery and architecture have evolved over the last 6,000 years beginning from hieroglyphics to drawings on printable media, from the "Golden Age" of engineering graphics to the innovation of computer graphics and prototyping. The evolution of engineering design graphics as a profession has also evolved. Years…

A multidimensional item response theory (IRT) model for polytomously scored items, based on the graded response model and using the normal ogive, is developed; and an EM algorithm that may be used to estimate the parameters of the model is also discussed. The model is illustrated through a simulation study in which the polytomous item responses of…

Intended for journalism school instructors and administrators as they make decisions about purchasing computers to help teach graphics and typology, this guide discusses seven areas of weakness in journalism curricula and ways in which schools should prepare themselves for new technologies. The introduction first discusses WYSIWYG--"what you see…

Discusses the use of computer assisted instruction in the medical education program of the Kirksville College of Osteopathic Medicine (Missouri). Describes the animation techniques used in a series of simulations for microbiology. (TW)

Discusses contributions that computers and computer networks are making to the field of medicine. Emphasizes the computer's speed in storing and retrieving data. Suggests that doctors may soon be able to use computers to advise on diagnosis and treatment. (TW)

Describes experiences with turtle graphics to demonstrate motion in a constant gravitational field. Provides the computer program and typical diagrams. (YP)

Presents practical teaching suggestions selected from commercially available materials and also submitted by readers that can easily be adapted to different grade levels. Contains eight computer based activities which provide experience with spreadsheets, random number functioning, word puzzles, survey plotting, graphics, and Logo programming. (ML)

Virtual reality (VR) is a new computational paradigm that redefines the interface between human and computer. VR may result in a significant improvement over traditional instruction because it is not only a multimedia interactive tool but also a learning environment extremely close to reality. Few empirical studies have been done on the use of VR…

Discusses the use of microcomputers in the construction and operation of business and management games and proposes changes in the conceptual framework within which games are designed. Topics discussed include the dynamics of business games; the use of graphical displays; simulation of competitor strategies; networking; and software integration.…

Presents a theoretical rationale for the idea that computer programs simulating written conversation, and using natural language, could be effective in language teaching and remediation, and reports empirical studies of its potential. Studies with 10- to 14-year-old language-impaired children are described, software is explained, and future…
