A light box is an apparatus designed to show the logical states of the User Port Pins of a PET microcomputer. Details of this aspect of computer studies are provided to introduce students to the possibilities of microprocessor control. Details of PET User Port interface and sample programs are included. (Author/JN)

Some aspects of animation that are on the Apple-microcomputer are presented. Shape tables are described and several programs that illustrate important concepts are included. The concept of animation is viewed as being very simple and the process is clearly detailed. (MP)

Ten computer languages are compared and contrasted. A series of programs focusing on the average of two numbers are designed to point out differences in console input, console output, and common arithmetic. (MP)

The internal operations of this computer symbolic mathematics system are described in detail in order to explain the accomplishments of the computer. (MP)

The use of several features of BASIC programs is examined. Examples of programs and self-tests are included. (MN)

This collection reprints six articles which deal with mathematics and the ways in which computers can help teach even young children about mathematics. The subjects of the articles are: teaching children thinking; teaching children to be mathematicians versus teaching about mathematics; on making a theorem for a child; a computer laboratory for…

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…

GLISP is a high-level computer language (based on Lisp and including Lisp as a sublanguage) which is compiled into Lisp. GLISP programs are compiled relative to a knowledge base of object descriptions, a form of abstract datatypes. A primary goal of the use of abstract datatypes in GLISP is to allow program code to be written in terms of objects,…

Procedures are presented to assist programers with the use of the Coursewriter II preprocessor. The preprocessor was designed to reduce the repetition of effort which takes place from the conception of a course by its author to the time of its use by students in on-line instruction. It accomplishes this by relieving the programer of the tedious…

A lack of comprehensive up-to-date textbooks designed specifically for use in the computers in the education field motivated the development of this resource handbook. There are major sections entitled: computers in education; teaching about computers; the computer as an aid to learning; the computer as a teacher; the computer as a classroom…

After consideration of two recent examples of instruction sets for microprogramable computers, the article sketches known and new results about complete sets of functions which appear to be applicable to microlanguage development. Some needed areas of research are pointed out. Functional completeness is linked to research in control primitives for…

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…

A comparison between PASCAL and BASIC as general purpose microprocessor languages rates PASCAL above BASIC in such points as program structure, data types, structuring methods, control structures, procedures and functions, and ease in learning. (CMV)
