Developed in response to the complex problems involved in providing equal educational opportunities for the intellectually alert orthopedically handicapped, the PLATO Programmable Terminal Keyset (PPTK) system makes the resources of PLATO compatible to the functional problems of a wide range of orthopedic conditions. This report describes the…

Noting that the use of all-capital print on microcomputer screens eliminates the configuration clues (ascending and descending letters that create the physical shape of the word) that help a reader recognize a word and read more quickly, a study was conducted to examine the effect of all-capital print versus standard mixed print on reading speed…

This paper describes the way in which a child is introduced to LOGO, which is both a programming language and an environment or a way of thinking about computers and about learning. After a brief description of the devices used by LOGO, the process of acquainting a student with the system is explained. The strong anthropomorphization of components…

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…
