Learning to program involves developing an understanding of two hierarchies of concepts. One hierarchy consists of data and extends from very literal data (which represents only itself) to very abstract data incorporating variable values in complex interrelationships. The other hierarchy consists of the operations performed on the data and extends…

Data from a brief survey of current and potential uses of minicomputers in small educational institutions suggests that the principal role of minicomputers in such institutions will be for school administration and for teaching the use of computers. In the instructional area, emphasis should be placed on teaching (1) the potentials and…

The first section of this course on programming introduces LISP as a programming language designed to do symbol manipulation, with consequent prevalence in auto-instructional (AI) work. A programming language specifies in its description a number of primitive operations which the computer knows how to perform. An algorithm is the set of…

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…

This paper discusses some of the ways one can study graphics on the Apple II microcomputer. Much attention is given to specialized use of software packages used in dumping graphics, and the saving or storing of binary files of graphic images. Knowledge of BASIC at more than a cursory level is required, but a step-by-step procedural outline is…

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…

The computer programing language APL is used to describe a "learning" game, and the functions developed are generalized to extend to a class of rules. (Author/WH)

Computers are changing the lives of millions of people, but schools are still not producing many computer literate students. Rapid improvements in hardware technology and major progress in the development of software have put computers within reach of everyone. Computer literacy must now be treated as a functional tool similar to reading, writing,…

This paper discusses five points related to developmental research on children learning to do Logo programming: (1) systematic developmental research documenting what children are learning as they learn to program is necessary; (2) Logo is cognitively complex beyond its early steps and difficult to learn without instructional guidance; (3) the…

This pilot study tested the hypothesis that the logical thinking skills of middle-grades students are enhanced by teaching them computer programming using the BASIC programming language. A quasi-experimental design was used with 36 students randomly selected and assigned to one of two treatment groups: 18 students received no instruction in…

This paper is concerned with providing automatically generated online explanations to the user of a user interface or "tool" about what the interface can and cannot do, and what parameters or options are available or required with a given command. The COUSIN interface system, developed at Carnegie-Mellon, supplies a cooperative…

NATAL is a high-level programming language designed to meet the requirements of the course author in the preparation of Computer Assisted Learning (CAL) materials. The basis for its design is found in the functional specification published by the National Research Council's Associate Committee on Instructional Technology; developers of the…

Because previous research by Bayman and Mayer (1983) suggests that individuals who attempt to learn their first computer language develop a variety of misconceptions of the meanings of individual programming statements, this study investigated whether it is possible to enhance beginning programmers' understanding of the programming statements…

APL (A Programing Language), a computer language used thus far largely for mathematical and scientific applications, can be used to tabulate a survey. Since this computer application can be appreciated by social scientists as well as mathematicians, it serves as an invaluable pedagogical tool for presenting APL to nonscientific users. An…

These papers describe efforts toward the systematic improvement of a software environment called SOLO (Eisenstadt, 1978), which has been used with cognitive psychology students at the Open University in Great Britain and is geared towards the manipulation of assertional databases. The first paper, by Eisenstadt, Laubsch, and Kahney, provides an…
