We introduce an effective computer aided learning visual tool (CALVT) to teach graph-based applications. We present the robot motion planning problem as an example of such applications. The proposed tool can be used to simulate and/or further to implement practical systems in different areas of computer science such as graphics, computational…

Describes a program in vegetable gardening developed by Purdue University specialists in horticulture and computer technology. This computer program offers residents of Indiana individual garden plans based on their own specifications. (CT)

This discussion of a new computer-based medium describes microcomputer (MC) painting and its principal tool, the MC paintbrush, and explores their potential roles in mathematics, computer science, and art education in secondary schools. This paper describes the school computer, discusses capabilities of MC painting, explains how MC painting is…

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…

The efficacy of using graphic representations of concepts, which are more readily generated on a computer than in traditional texts, was studied. The study, which involved teaching computer programming, is described. The necessity of further research is discussed. (JL)

Instructors teaching beginning programming classes are often interested in exercises that involve processing photographs (i.e., files stored as .jpeg). They may wish to offer activities such as color inversion, the color manipulation effects archived with pixel thresholding, or steganography, all of which Stevenson et al. [4] assert are sought by…

This paper describes a National Science Foundation-sponsored project at Louisiana Technological University to develop computer-based laboratories for "hands-on" introductions to major topics of computer science. The underlying strategy is to develop structured laboratory environments that present abstract concepts through the use of…

A pioneer program in computer graphics was implemented at Parkland College (Illinois) to meet the demand for specialized technicians to visualize data generated on high performance computers. In summer 1989, 23 students were accepted into the pilot program. Courses included C programming, calculus and analytic geometry, computer graphics, and…

Proposes to modify the procedure proposed by Abelson and diSessa to produce a polygonal path with vertices that lie exactly on an ellipse. Provides a detailed proof. Implements a limiting process to produce the best possible approximation to any ellipse for any given screen resolution. (CW)

The PLATO IV computer-based educational system contains its own communications hardware and software for operating plasma-panel graphics terminals. Key echoing is performed by the central processing unit: every key pressed at a terminal passes through the entire system before anything appears on the terminal's screen. Each terminal is guaranteed…

With support from the National Science Foundation and the University of California, the Physics Computer Development Project have produced in the last six years computer based material in a wide variety of modes. Among the major products are science learning dialogs, graphic additions to APL (A Programming Language), the underlying software, and…
