The effect of different communicating modes to computers on students' attitudes toward programing was studied. In a computer-related course, 13 students used batch processing mode to solve problems on the computer, while 12 other students used conversational mode to solve the same problems. It was found that those students accessing the computer…

This learning module for a secondary electronics course contains two lessons that teachers can use to help students do the following: (1) access an Apple II computer with a PZ-90 interface to read input ports and send information to output ports with the aid of a computer program; and (2) demonstrate the use and relationship of binary numbers in…

A series of three booklets provides elementary and secondary students who are participating in the Southeast Alternatives Program run by Special School District Number 1 in Minneapolis with some fundamental information about computers and their use. The first volume offers some general background on computers and describes the use of the teletype…

Intended for use by educators, educational administrators, and directors of training within industry, this guide lists commercially available products and services in the field of computers and education. It contains descriptive information wherever possible and comparison charts designed to enable the prospective user to make a preliminary…

Describes the nature of modern general-purpose computer systems, including hardware, semiconductor electronics, microprocessors, computer architecture, input output technology, and system control programs. Seven suggested readings are cited. (FM)

Supplying data from mainframe computers to microcomputers is tedious because IBM mainframe computers use Extended Binary-Coded Decimal Interchange Code (EBCDIC) to represent data and microcomputers use an American National Standard Code for Information Interchange (ASCII) code set. (MLF)

If computers are to be used creatively in education, they should be made available to administrators, teachers, and students. Educational Data Processing (EDP) is a means to this end. Small and poor systems can join in cooperative county, state or regional computer systems efforts such as the New England Educational Data Systems (NEEDS) in whose…

The bewildering number of available terminals which are offered to CAI users presents a rather formidable problem of which one to choose. This article surveys what appear to be evolving standards for terminals. The usefulness of these terminals for CAI purposes is discussed, together with the best known prototype exhibiting the particular feature.…

More and more secondary schools are becoming interested in introducing their students to computers and computer concepts. A central problem for such schools, however, is obtaining reliable computer service with capacity for all the students who are interested, but at a cost the school can afford. Although many schools use commercial or small-scale…

The equipment and procedures used in computer word processing (CWP), the merging of word processing with an electronic data processing computer system, are described. Training of personnel to operate the system is briefly discussed. (MS)

Computer software for process control has the primary function of communicating with and governing physical devices. The structure of such software, process-control systems, multitask systems, message passing, problems of deadlock, distributed computer systems, and protection against failure in process-control systems are among the areas examined.…

More than 90 computer terminals are used at Lamar University (Texas) for a number of functions, including classes, admission, registration, fee payment, catalog editing, and the handling of the university's investments. (MLF)

In context of an instrumentation course, four ocean engineering students set out to design and construct a micro-computer based data acquisition system that would be compatible with the University's CYBER host computer. The project included hardware design in the area of sampling, analog-to-digital conversion and timing coordination. It also…

Although the indispensibility of access control mechanisms in data secure systems has been recognized, there is a need for more subtle protection and refined control mechanisms. This report describes context protection mechanisms which enable the same data unit to be protected differently in different contexts, the differences being determined by…

An important development in the computerization of society is the development of the ability to communicate with a computer through human speech. Speech recognition machines with limited capabilities are available today. (BB)
