Reviews the development of authoring systems from those present in mainframe computers to the newest versions in desktop training systems. Advances in microcomputers and the corresponding authoring systems are described, programing languages are discussed, and computer-based instructional development that includes graphical user interfaces and…

Describes the evolution of scientific visualization in technical and engineering graphics. Outlines a scientific-technical visualization curriculum illustrated with applications. Discusses the role of technology education in the new curriculum. (SK)

Discusses online help systems in application software design and describes two experiments in which adult computer novices learned to use experimental graphics software by task-based exploration. Topics include operative help; function-oriented help; effects on learning performance; schemata; mental models; and implications for the design of…

Describes the integration of these topics through a major team-based design and computer aided design (CAD) modeling project in freshman engineering graphics at the University of Western Ontario. Involves n=250 students working in teams of four to design and document an original Lego toy. Includes 12 references. (Author/YDS)

Presents a lesson developed for a Montessori Elementary Level II class using the Turtle Math program. Students used mathematics, geometry, and logical thinking to identify the basic formula for drawing stars with any desired number of points. (KB)

This brief article presents a story contributed by Tim Comolli, Imaging Lab teacher at South Burlington High School in Vermont, and 40 year teaching veteran. The story describes the tale of a youngster who changed Comolli's life and permitted him to succeed in helping countless other students in the past years. The young man in the story comes…

Digital photos and digital movies offer an excellent way of bringing real world situations into the mathematics classroom. The technologies surveyed here are feasible for everyday classroom use and inexpensive. Examples are drawn from the teaching of Cartesian coordinates, linear functions, ratio and Pythagoras' theorem using still images, and…

Boundary extension is a tendency to remember close-up scenes as if they extended beyond the occluding boundaries. The authors explored the contributing factors using brief retention intervals and computer-generated images. Boundary extension turns out to be more complex than previously thought and is not linked to the effects of image…

Following a pretest, 8 participants who were unfamiliar with algebraic and trigonometric functions received a brief presentation on the rectangular coordinate system. Next, they participated in a computer-interactive matching-to-sample procedure that trained formula-to-formula and formula-to-graph relations. Then, they were exposed to 40 novel…

This author relates how she came upon the idea of using an image-editing program to virtually install monumental sculptures into real-life landscapes in her desire to bring technology and sculpture together in her art class. In this article, she describes how she made her class create tabletop-sized sculptures and photographs of digital…

A small class of functions is described that easily lend themselves to two-dimensional and three-dimensional visualizations at the basic calculus level. The intended audience is those educators involved in the instruction of elementary calculus. This note is an educational piece that begins with the question: "What happens if a function defined on…

With the shift in numbers between Canadian-born students in the university classroom and the increased number of international students, it is a primary concern for instructors and instructional designers to know and understand learner characteristics in order to create effective instructional messages and materials. Recognizing how culture might…

Mathematical knowledge can be categorized in different ways. One commonly used way is to distinguish between procedural mathematical knowledge and conceptual mathematical knowledge. Procedural knowledge of mathematics refers to formal language, symbols, algorithms, and rules. Conceptual knowledge is essential for meaningful understanding of…

Many electronic portfolios become shining but superficial collections instead of environments for nurturing insight. Instructors must balance instructional time between perfecting the technical expertise of the student and fully developing the critical expertise needed for the student to become a thoughtful scholar. In a deliberate move, I have…

Complex computer and video games may provide a vehicle, based on appropriate theoretical concepts, to transform the educational landscape. Building on the original game object model (GOM) a new more detailed model is developed to support concepts that educational computer games should: be relevant, explorative, emotive, engaging, and include…
