The National Science Foundation (NSF) has awarded support for supercomputer centers at Cornell University, Princeton University, University of California (San Diego), and University of Illinois. These centers are to be the nucleus of a national academic network for use by scientists and engineers throughout the United States. (DH)

Illustrates use of analog/logic computer to produce realistic display of the actual motion of computer simulations in addition to the usual variable-versus-time solution. An arbitrary vector-generating circuit is postulated and utilized in several examples, the most general of which shows vector length, angle, and position all changing with time.…

Discusses the nature and development of computer software. Programing, programing languages, types of software (including dynamic spreadsheets), and software of the future are among the topics considered. (JN)

Mathematical modeling problems encountered in many disciplines are discussed in terms of the modeling process and applications of models. The models are classified according to three types of abstraction: continuous-space-continuous-time, discrete-space-continuous-time, and discrete-space-discrete-time. Limitations in different kinds of modeling…

Discusses producing effective instructional software using a balance of course content and technological capabilities. Describes six phases of an instructional development model: discovery, design, development, coding, documentation, and delivery. Notes that good instructional design should have learner/computer interaction, sequencing of…
