An inexpensive device to assist in teaching the main ideas of Public Key encryption and its use in class to illustrate the operation of public key encryption is described. It illustrates that there are two keys, and is particularly useful for illustrating that privacy is achieved by using the public key. Initial data from in class use seem to…

Information systems educators must balance the need to protect the stability, availability, and security of computer laboratories with the learning objectives of various courses. In advanced courses where students need to install, configure, and otherwise manipulate application and operating system settings, this is especially problematic as these…

Functions are all around us, disguised as actions on concrete objects. Composition of functions, too, is all around us, because these actions can be performed in succession, the output of one serving as the input for the next. In terms of Gray and Tall's (2001) "embodied objects" or Lakoff and Nunez's (2000) "mathematical idea…

In addition to the input/output record format, the program flowchart, the program listing, and the program test output, eight documentation items are suggested in order that they may serve as a base from which to start teaching program documentation. (Author/AG)

SLIP (Symmetric List Processing) is a list processing system designed to be added to a higher order language (PL-1 in this version) so that the user has available to him list processing powers. The primary value of such a system is its data handling power. Through SLIP, one can set up lists of data, scan those lists, alter them, and read or write…

An Interactive Decision System (AIDS) is described as a computer-based technique to rationalize the judgment process. This technique is intended to allow a typical manager to make decisions with more complete use of information available and fewer loose ends than is usually the case. (Author)

Recently a number of experiments have been performed whose aim was to compare programming language features to determine which programming language features programmers found difficult to use. This paper examines these experiments in light of the evidence that programming language designers would find most useful. (Author)

Describes an instrument created to measure the general level of computer literacy of high school students and to obtain baseline data on student awareness of computer concepts. (Author/IRT)

The use of overhead transparencies can enhance the whole-to-parts method of teaching computer concepts.

Computer applications in music, especially with regard to research in music folklore, are discussed. (CK)

Working definitions of words related to the theory and use of computers are presented to introduce the novice to terminology. The glossary is not designed to be exhaustive. (Author/CM)

Ada is a programing language developed for the Department of Defense, with a registered trademark. It was named for Ada Augusta, coworker of Charles Babbage and the world's first programer. The Department of Defense hopes to prevent variations and to establish Ada as a consistent, standardized language. (MNS)
