The potentialities of specialized languages, in comparison to those of other types of specialized systems, are discussed. The point is made that these languages have been invented by information processing professionals in order to assist the problem-solving activities of computer users by providing them with appropriate interfaces to the…

The Teacher-Interactive Computer System (TICS) is an on-line and interactive programing system for authoring interactive programs, particularly instructional programs. The system provides a fairly natural language, in which the author's statements for creating items in a program, for examining the structure and flow, for simulating its use by…

The design and operation of a time-sharing monitor are described. It runs under OS/360 MVT that supports multiple application program interaction with operators of CRT (cathode ray tube) display stations and of a teletype. Key design features discussed include: 1) an interface allowing application programs to be coded in either PL/I or assembler…

To improve the instructional process, time shared computer-assisted instructional methods were developed to teach upper division undergraduate chemical engineering students the concepts of process simulation and analysis. The interactive computer simulation aimed at enabling the student to learn the difficult concepts of process dynamics by…

A description of the Program Assembly and Monitored Execution for Learning Applications (PAMELA) is presented. It is intended for instructors who propose to use the system and for programers who wish to modify it. PAMELA is an interactive system designed to teach the operating principles of the IBM System/360 digital computer at the machine…

A series of graphically-oriented computer-assisted instructional (CAI) lessons in elementary beam theory has been developed for an undergraduate course in solid mechanics. The lessons were implemented on the PLATO CAI system at the University of Illinois; the system included a graphical display unit (CRT) and a CDC 1604 computer. The first phase…

Engineering is coming to rely more and more heavily upon the computer for computations, analyses, and graphic displays which aid the design process. A general purpose simulation system, the Time-shared Automatic Control Laboratory (TACL), and a set of computer-aided design programs, Control Oriented Interactive Graphic Analysis and Design…

The computer is currently a vital tool in engineering analysis and design. With the introduction of moderately priced graphics terminals, it will become even more important in the future as rapid graphic interaction between the engineer and the computer becomes more feasible in computer-aided design (CAD). To provide a vehicle for introducing…

A two-stage project is investigating the educational potential of a low-cost time-sharing system used as a simulation tool in Electrical Engineering (EE) education. Phase I involves a pilot study and Phase II a full integration. The system employs interactive computer simulation to teach engineering concepts which are not well handled by…

An interactive computer-assisted instructional (CAI) system, called CODE, is used to teach transactional analysis, or coding, in elementary accounting. The first major component of CODE is TEACH, a program which controls student input and output. Following the statement of a financial position on a cathode ray tube, TEACH describes an event to…

Computer-assisted instruction supplements traditional methods in a non-calculus physics course offered at Seattle Pacific College. Thirty-five science majors enrolled in the first quarter and 32 continued in the second term. The hardware for the course consists of a PDP-11/20 computer and eight teletype terminals; additional peripheral equipment…

A ten-year research study designed a mechanized information system in the information processing field. Special attention was paid to implementation criteria entering into on-line retrieval through man-machine dialog from a remote typewriter or video terminal and four major areas were investigated: search strategies, machine stored indexer aids,…

A new technique called computer augmented lectures (CAL) now in use at the University of Texas at Austin is discussed in this report. The technique is described as involving the integration of on-line interactive time-sharing computer terminals and theater-size video projectors for large screen display, the goal being to promote student learning…
