Many a great idea has first taken shape as a simple drawing sketched by hand on a piece of paper, but in an increasingly high-tech world, such drawings are more often being created--or at the very least perfected--with the aid of a computer. And in today's highly automated workplace, manufacturing a finished product from that great idea will…

One of the objectives of the process technology curriculum at Wageningen University is that students learn how to design mathematical models in the context of process engineering, using a systematic problem analysis approach. Students find it difficult to learn to design a model and little material exists to meet this learning objective. For these…

Each school year, the author's intermediate art students look forward to this unique self-portrait assignment. Chuck Close's photorealistic portraits are the inspiration for this assignment. The lesson incorporates technology using digital cameras and an image-manipulation computer program. The lesson is introduced with a brief overview of Chuck…

Over the past decade the software products available for solid modeling, dynamic, stress, thermal, and flow analysis, and computer-aiding manufacturing (CAM) have become more powerful, affordable, and easier to use. At the same time it has become increasingly important for students to gain concurrent engineering design and systems integration…

Cubic symmetry is used to build the other four Platonic solids and some formalism from classical geometry is introduced. Initially, the approach is via geometric construction, e.g., the "golden ratio" is necessary to construct an icosahedron with pentagonal faces. Then conventional elementary vector algebra is used to extract quantitative…

Reports on a project that extended the Engineering Design Graphics curriculum to include instruction and laboratory experience in computer-aided design, analysis, and manufacturing (CAD/CAM). Discusses issues in project implementation, including introduction of finite element analysis to lower-division students, feasibility of classroom prototype…

Most, if not all, systems have a mechanism that collects information to facilitate monitoring performance. This information is primarily used to modify the system to make it more efficient in performing desired tasks and, thus, attaining desired results. Similar to electrical, mechanical, or hydraulic systems, the feedback mechanism in an…

With new and inexpensive computer-based methods, measuring the speed of light and the Earth's radius--historically difficult endeavors--can be simple enough to be tackled by high school and college students working in labs that have limited budgets. In this article, the author describes two methods of estimating the Earth's radius using two…

If we intend to teach through educational media, we also have to teach about those media. This article explores the implications of this perspective for the use of computer games in the classroom. It seeks to explain why and how teachers might teach about computer games as a medium in their own right, just as they teach about film or television or…

Experimental learning environments based on simulation usually require monitoring and adaptation to the actions the users carry out. Some systems provide this functionality, but they do so in a way which is static or cannot be applied to problem solving tasks. In response to this problem, we propose a method based on the use of intermediate…

Describes an image database system assembled using separate computer components that was developed to overcome text-only computer hardware storage and retrieval limitations for a pavement design class. (JJK)

A project developed and evaluated an intermediate form of presentation that provides a virtual dynamic tactile display for use with computers that could complement static tactile displays of graphical material. The device is a two-dimensional extension of the tactile mouse and provides contour and slope information to the user. (Contains nine…

Design plays a central role in a range of subjects at different educational levels. Students have to acquire the knowledge necessary for the execution of tasks that enable them to construct an artefact or model that can be tested by simulation and that satisfies some requirements and verifies some constraints. They achieve this by means of a…

Teachers find themselves continually challenged to develop curricula, activities and strategies that satisfy evolving federal, state and district standards. The introduction of high-stakes testing and constantly changing reforms have brought about a significant shift in their responsibilities. With so much governmental focus on standards, teachers…
