Utilizes LOGO to teach the concept of inequalities by programing the turtle to take random walks in the coordinate plane restricted to predetermined regions defined by inequalities. The students task is to discover the inequalities that define the illegal areas into which the turtle must not move. Provides examples and corresponding computer…

Trends in the use of visualization (computer graphics) for instructional purposes are analyzed in three segments: (1) current classroom activities; (2) technically possible but not prevalent classroom activities; and (3) the future classroom. The discussion draws on University of Iowa efforts, national curricular innovations, and presentations and…

The results of an experiment in teaching engineering graphics using the traditional lecture-homework-laboratory technique are compared to a newer lecture homework proposal. Although the newer method reduces professor-student contact, it may prove to be as effective as the older method requiring laboratory instruction. (KR)

Presented is a proposed formula for determining the bearing angle and the slope angle for the line of intersection using the strike and dip angles of two given plane segments. Included is the development of the formula and three example problems. (KR)

Two graphics interface packages, PHIGS and HOOPS, are examined. A comparison of the two packages is made in light of the Iowa State University College of Engineering's need for educational software. Conclusions based on programing experience using both PHIGS and HOOPS are presented. (KR)

Discussion of graphing software for educational purposes focuses on a study in which three versions of an original computer graphing program were used by inner-city high school students to solve scientific data analysis problems. Variations in degrees of flexibility and feedback in the software are explored. (Contains 37 references.) (LRW)

Discusses the origins of an exemplary model to serve as a guide for the implementation of computer graphics in the art classroom. Describes how the "Indiana Computer Graphics Cadre" developed a curriculum guide and organized workshops to instruct other art teachers in this area. (KM)

Describes the architecture of the prototype of an image management system that has been used to develop an application concerning images of frescoes in the Sistina Chapel in the Vatican. Hardware and software design are described, the use of local area networks (LANs) is discussed, and data organization is explained. (15 references) (LRW)

Describes a development project for the use of computer graphics and video in connection with an inservice training course for primary education teachers in Denmark. Topics addressed include research approaches to computers; computer graphics in learning processes; activities relating to computer graphics; the role of the teacher; and student…

Investigates the effects of audio and text density on the achievement, time-in-program, and attitudes of 134 undergraduate students. Data concerning pre-existing computer skills/experience and demographic information were also collected. Findings have implications for the use of audio, text and graphics in the design of computer-based instruction.…

Provides basic guidelines for designing and creating a faculty Web site using a systems approach. Describes instructional design principles used in Web site design, including considering the target audience, clear objectives, home page and contents, site navigation structure, page design, text and graphics, and selecting a Web authoring program.…

Hypermedia-based courseware used at the University of Alabama for optometric education is described, focusing on these key features: uses of graphics; interactivity and navigation options; and capacity for printing course material, including both text and graphics, for handouts. The system has been found effective in both a multiinstructor…

Examines the nature and future of computer graphics as an art form. Characterizes four basic beliefs about art and considers their relevance to computer graphics. Discusses the special qualities of computer graphics and how they can enrich art instruction. (MJP)

"Bohr's Atomic Model" is a small interactive multimedia program that introduces the viewer to a simplified model of the atom. This interactive simulation lets students build an atom using an atomic construction set. The underlying design methodology for "Bohr's Atomic Model" is model-centered instruction, which means the central model of the…

Describes projects in a fifth grade classroom that used data collection and graph making activities as part of a collaborative project between the teacher and the library media specialist. Discusses the use of Excel spreadsheets, comparing the effectiveness of different types of graphs, and project planning. (LRW)
