A 90-minute computer-assisted instruction (CAI) unit course supplemented by a 1-hour lecture on the dynamic nature of three-dimensional rotations and Euler angles was given to 29 undergraduate engineering students. The area of Euler angles was selected because it is essential to problem-working in three-dimensional rotations of a rigid body, yet…

A general description is provided of the "geometric dictionary," a graphic display aid, used by the Computer-Assisted Instruction Laboratory at the Pennsylvania State University. The purpose of the description is to enable the reader to duplicate and use the dictionary on any cathode ray tube terminal of the IBM 1500 system. The major…

An On-Line Modeling System (OLMS) which should be particularly useful to the biomedical community is described which utilizes a process called "overlaying" to simplify loading and executing programs. OLMS has been constructed and implemented as an interpreter; that is, a program that translates and then executes each source statement in…

A manual describes the use of graphic commands in student-computer dialogues. How to construct axes, windows, boxes and various other computer displays is explained, in particular reference to the ARDS 100 and TEKTRONIX 4002 and 4010 computer terminals. Concrete examples of displays are included. The appendix contains an explanation of the use of…

An existing computer program for computing multiple regression analyses is made interactive in order to alleviate core storage requirements. Also, some improvements in the graphics aspects of the program are included. (JKS)

Guidelines are presented for evaluating the desirability of interactive computer graphic systems in various engineering disciplines. (BB)

Describes significant attributes of expert systems, contrasts them to conventional computer systems, and provides an overview of the R1 expert system used by Digital Equipment Corporation (DEC) to put together operational systems that meet customers' requirements. Document handling, particularly pictures and images in documents, is also briefly…

This article describes a high school art teacher's experience in developing a computer art course for her students. Included are six examples of computer art created by her students. (JDH)

To many students the complex technical problems of computer graphics seem to put them beyond reach. Computer technology can be reduced to the bare basics, however. In this activity elementary art students add an intriguing dimension to a crayon drawing by completing a computer image counterpart of a previously drawn image. (RM)

A computer-based method for producing 35mm color slides has been used in Ohio State University's College of Dentistry. The method can produce both text and slides in less than two hours, providing substantial flexibility in planning and revising visual presentations. (Author/MLW)

Interactive computer graphics is fast becoming the standard medium of communication between computers and all kinds of users. Reasons for this trend, the technology of interactive graphics displays, software considerations, applications (including classroom and laboratory applications), and future developments are discussed. (JN)

Relates experiences of an elementary school reading teacher and a group of fifth- and sixth-grade students in exploring the computer programing language Logo. Use of a tree-like figure as an illustration for the concept of recursion is described. Programing commands and graphic illustrations are included. (EJS)

Presents a programing subroutine which will create a graphical plot that occupies any number of columns specified by user and will run with versions of BASIC programming language. Illustrations of the subroutine's ability to operate successfully for three possibilities (negative values, positive values, and both positive and negative values) are…

This study assesses the relationship of student performance using two microcomputer instructional application software designs, one with graphics and the other without graphics, as a teaching aid in comma usage. Results indicated that there was no significant difference in performance between the graphic and nongraphic treatment groups. (CT)

Presents the listing (and documentation) for an arithmetic drill program with color graphics and sound. The program offers simple arithmetic problems illustrated by colorful dinosaurs. A buzzer sounds if an answer is incorrect while a short piece of dinosaur music is heard if an answer is correct. (JN)
