Offers a method for interactive design of objects on a computer. Outlines a method which allows the designer to interact with orthogonal views to construct a three dimensional model of an arbitrary shape. Presents an algorithm based on the Bezier curves to efficiently create smooth curves and surfaces. (CW)

Reviews three softwre packages: "Molecular Graphics on the Apple Microcomputer, Enhanced Version 2.0"; "Molecular Graphics on the IBM PC Microcomputer"; and "Molecular Animator, IBM PC Version." Packages are rated based on ease of use, subject matter content, pedagogic value, and student reaction. (CW)

Presents the results of statistical analyses and interpretations of data obtained from students in two engineering fundamentals courses on an attitudinal survey. Indicates positive and significant improvement in student attitudes toward their own drawing abilities and the importance of drawing in their lives and careers. (CW)

Advanced Education Projects (AEPs) are a series of multidisciplinary, advanced experiments in educational computing supported by IBM and currently in progress at 19 leading universities. Each AEP has established a series of curricular experiments to explore the use of workstations and network technologies as part of the instructional process. The…

This agenda lists activities scheduled for the second IBM (International Business Machines) Academic Information Systems University AEP (Advanced Education Projects) Conference, which was designed to afford the universities participating in the IBM-sponsored AEPs an opportunity to demonstrate their AEP experiments in educational computing. In…

Explores several concepts in computer assisted design/computer assisted manufacturing (CAD/CAM). Defines, evaluates, reviews and compares advanced computer-aided geometric modeling and analysis techniques. Presents the results of a survey to establish the capabilities of minicomputer based-systems with the CAD/CAM packages evaluated. (CW)

Presents current trends in the development of expert systems within the Department of the Navy, particularly research into expert graphics systems intended to support the Authoring Instructional Methods (AIM) research project. Defines artificial intelligence and expert systems. Discusses the operations and functions of the Navy's intelligent…

Argues for a legitimate role of manually expressed engineering graphics within engineering education as a needed support for computer-assisted drafting work. Discusses what and how students should learn as well as trends in engineering graphics education. Compares and contrasts manual and computer drafting methods. (CW)

Suggests a method of integrating teaching microcomputer graphics in engineering curricula without encroaching on the fundamental engineering courses. Includes examples of engineering graphics produced by commercial programs and others produced by high-level language programing in a limited credit hour segment of an educational program. (CW)

Because density is unobservable and must be inferred from knowledge about weight and size, it is a difficult concept to teach and learn. Even after traditional instruction, many students still have an undifferentiated concept that mixes characteristics of both weight and density. In this study, researchers tested the effectiveness of a unit they…

Discusses the similarities, differences, advanced features, applications and number of users of five microcomputer computer-aided design (CAD) packages. Included are: "AutoCAD (V.2.17)"; "CADKEY (V.2.0)"; "CADVANCE (V.1.0)"; "Super MicroCAD"; and "VersaCAD Advanced (V.4.00)." Describes the…

Describes the various phases of software development and shows how it can be used in an engineering graphics course. Includes demonstration exercises, practice exercises, code development and software as they have been used at Clemson University. (CW)

Two classroom studies, one conducted in the spring of 1985 and the second in the spring of 1986, showed that many high school students do not differentiate between heat and temperature; instead, they have a single concept that contains some of the features of heat and some of the features of temperature. Because the distinction between these two…

Density is the first intensive physical quantity students encounter that can be understood in terms of an underlying model, the particulate theory of matter. Learning about density provides students with explanations for a range of phenomena such as sinking and floating, and changes of state. Teachers report, however, that density is a difficult…
