Two kinds of secret writing, codes and ciphers, are discussed. The weakness of a ciphering system mentioned in the March 1981 issue is pointed out, and an alternate method is presented. Programs written in BASIC are presented which can be used to encipher messages and help break ciphers. (MP)

Described and critiqued are two ideas which have proven valuable in teaching programming at the introductory level, the mental model and the programming plan. (PK)

In describing two examples of students asked to write programs to solve problems, a serious defect in training is illustrated with potentially important consequences for students and employers. (Author)

It is noted that there are some integrals which cannot be evaluated by determining an antiderivative, and these integrals must be subjected to other techniques. Numerical integration is one such method; it provides a sum that is an approximate value for some integral types. This module's purpose is to introduce methods of numerical integration and…

Computer-assisted instruction (CAI) during the decade of the 60's was characterized by a number of limiting factors: insufficiently powerful computers and terminals, restriction to a few rigid "teaching strategies," and the splitting of resources among too many projects below critical size. During the present decade, CAI has undergone a…

A method for improving the induction of computer programs from human problem solving protocols begins with four steps. The first step requires dividing the protocol into phrases that represent the performer's single assertions about the task or a single act of task oriented behavior. Second, the operators and information constituting single states…

Provided are names and school districts of elementary and senior division winners of the third annual international problem-solving contest. Feedback from participants, contest recommendations, and information on the 1984 contest are included. (JN)

Provides background material on logic programing and presents PROLOG as a high-level artificial intelligence programing language that borrows its basic constructs from logic. Suggests the language is one which will help the educator to achieve various goals, particularly the promotion of problem solving ability. (MVL)

A description is provided of a computer system designed to aid in the analysis of student programing work. The first section of the report consists of an overview and user's guide. In it, the system input is described in terms of a "dribble file" which records all student inputs generated; also an introduction is given to the aids…

Describes a course that emphasizes methods of problem-solving rather than learning a particular programing language. (MLH)

The development of symbolic computer algebra designed to manipulate abstract mathematical expressions is discussed. The ability of this software to mimic the standard patterns of human problem solving represents a major advance toward "true" artificial intelligence. (MP)

Answers to problems (in Applesoft Basic) in the Second Annual Computer Problem Solving Contest are presented, corresponding to elementary/junior/senior levels. Problems require good control of programing language, ability to solve problems, and implementing a problem-solving strategy within a computer language. Problem types include words,…

These student materials--study guides, handouts (some are manuals), a workbook, and programmed texts--for a secondary-postsecondary-level course for communications computer programmer are one of a number of military-developed curriculum packages selected for adaptation to vocational instruction and curriculum development in a civilian setting. A…

Discusses a study which investigated whether a computer simulation model could suggest subroutines that were instructable and whether instruction on these subroutines could facilitate subjects' solutions to the problem task. (JM)

Suggestions for five activities are presented. They include: ideas for several student problem-solving projects; preparing a flowsheet and program for 10 coin and dice games; using word processor formatting commands to create word designs; creating sounds; and writing a program to print out sums indefinitely.
