Describes the preparation of preservice secondary mathematics teachers in the uses and implications of classroom technology. Presents four areas of technology: (1) programing; (2) utility programs; (3) calculators; and (4) implementation of instructional software and communication packages. (Author/YP)

Discusses the golden ratio and how to make golden triangles using recursive Logo programs. Presents some outputs of the Penrose tile patterns. (YP)

Describes a system that combines computer-assisted learning (CAL) with interactive video. It was designed in England for an undergraduate pathology course. Hardware, based on a BBC microcomputer, is described; the design of interactive graphics is explained; and the tutorial design, using an authoring system, is discussed. (26 references) (LRW)

Reports on a study of university students that evaluated presentation styles in computer-assisted learning (CAL) and computer-based training (CBT) programs. Monochrome and colored textual presentations are compared, differences between computer-naive and computer-literate users are explored, and implications for the design of CAL and CBT programs…

Description of academic computing services at Syracuse University focuses on surveys of students and faculty that have identified hardware and software use, problems encountered, prior computer experience, and attitudes toward computers. Advances in microcomputers, word processing, and graphics are described; resource allocation is discussed; and…

Describes experiences for engineering students to develop spatial awareness and reasoning capability. Describes geometric modeling, basic geometric concepts, operations, surface modeling, and conclusions. (YP)

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)

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.…

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…
