A unified theory of planning and debugging is explored by designing a problem solving program called PATN. PATN uses an augmented transition network (ATN) to represent a broad range of planning techniques, including identification, decomposition, and reformulation. (The ATN is a simple yet powerful formalism which has been effectively utilized in…

The Lister Hill National Center for Biomedical Communications has supported a program to develop a Plasma Terminal System for purposes of improving the effective delivery of computer based educational materials. This system, employing recent advances in microprocessing and storage technologies, will provide new alternatives for present users of…

This paper describes a system which operates on an independent basis as well as connected to communications network, e.g., PLATO and ASCII based communication systems. The system also has facilities for local production and use of PILOT lessons, for support of a generalized programming language (NSBASIC), and for development of graphic sequences.…

This description of the System for Automated Typesetting (SCAT), an automated system for typesetting text and inserting special graphic symbols in programmed instructional materials created by the computer aided authoring system AUTHOR, provides an outline of the design architecture of the system and an overview including the component…

The prospect of videotex services becoming available and widely used throughout Canada presents potential problems. It is important that the industry structure that evolves for videotex be one in which society-as-a-whole benefits as well as individuals. To insure that this happens, the Canadian government should formulate policies to (1) ensure…

The method of phase-plane presentation as an educational tool in the study of the dynamic behavior of systems is discussed. In the treatment of nonlinear or piecewise-linear systems, the phase-plane portrait is used to exhibit the nature of singular points, regions of stability, and switching lines to aid comprehension. A technique is described by…

The developmental background and rationale are given for an introductory course in computers. Using computer art as the vehicle for instruction, this course is designed for people in disciplines other than computer science. The 16-week course syllabus described contains a weekly lecture, laboratory activities, assignments, and final exams. Several…

A computer program has been developed that will accept as inputs the physical description of a portion of land, and the parking design standards to be followed. The program will then give as outputs the numerical and graphical descriptions of the maximum-density parking lot for that portion of land. The problem has been treated as a standard…

The recent developments in computer hardware and software are presented to inform architects of this design tool. Technical advancements in equipment include--(1) cathode ray tube displays, (2) light pens, (3) print-out and photo copying attachments, (4) controls for comparison and selection of images, (5) chording keyboards, (6) plotters, and (7)…

An electronics graphic symbol set for on-line construction of electrical and electronics schematic diagrams is described. Specific procedures involving off-line and on-line activities are presented for the development and entry of schematic diagrams utilizing a stored set of symbols. An example of the commands and coding required for the…

Four new Project Solo modules are presented. A module on computer graphing with an x-y plotter explains the format for input to the computer, demonstrates the effect of scaling, and gives several on-line exercises to produce graphs. Several student-written programs in elementary and advanced mathematics, French, and U.S. history show how peer…

A technique is described for the generation of perspective views of three-dimensional models using computer graphics. The technique is applied to models of familiar thermodynamic phase diagrams and the results are presented for the ideal gas and van der Waals equations of state as well as the properties of liquid water and steam from the Steam…

This informal report describes uses of single-user, personalized computer systems at the University of Michigan and discusses the implications of new technologies for improving access to higher education. (Author/MP)

Establishes the need for literacy in dance; and describes two dance notation systems: the Massine notation method, and the Labanotation method. The use of interactive computer graphics as a tool for both learning and interpreting dance notation is introduced. (Author/VT)

Describes the User Template Mode, a system in which a user, by means of a simple catechism, can initially select all the desired parameters and options from a set of generalized building blocks. Thereafter, he need only invoke the template to obtain his customized interactive display automatically. (Author/VT)
