This paper provides an historical and empirical critique of the claim that learning to program will promote the development of general higher mental functions. A developmental perspective on learning to program is provided which incorporates cognitive science studies of mental activities involved in programming, and highlights the importance of…

This study suggests a new model for the evaluation of educational software authoring systems and applies this model to a particular authoring system, CSR Trainer 4000. The model used is based on an integrated set of software engineering and instructional design principles. (Author/LRW)

Discusses difficulties of producing computer assisted learning (CAL) software economically. Proposed as a solution, modular programing is illustrated by describing production of a matrix algebra package. Use of special CAL modules and facilities provided by subroutine libraries are cited, and development of a package to teach matrix theory is…

Exploratory study aimed to investigate elements of geometrical concepts that children learn through Logo programing. A test designed to assess three components of length and angle was administered to 84 children who had learned Logo for one year and 92 who had not. Data indicated a positive effect of Logo work on some items, but not all.…

A model for learning mathematics is proposed which involves the components of using, discriminating, generalizing, and synthesizing. The ways pupils use Logo programs as tools within their projects and how the nature of their programming tools become more explicitly understood and generalized are discussed. (RH)

Reviews instructional design research and theory and relates it to the design of computer-based instructional materials. Instructional design guidelines are offered to aid software developers in making design decisions on three macrolevel and four microlevel of instruction. (Author/LRW)

Arguing that the production system for computer courseware has a strong impact on quality courseware development, this report offers an introduction into the relationships between instructional system design and software engineering, and investigates courseware quality as a means of identifying quality enhancement factors that can make the…

A study is reported in which 7 children (2 girls and 5 boys, 11 to 12 years of age) with a year of LOGO Programming experience were asked to think aloud about how a LOGO procedure would work, and then to predict by hand-simulation of the programs, what the graphics turtle "pen" would draw when the program was executed. While all children…

This study was designed to ascertain the relationships between the steps of a tool designed to link knowledge production and the needs of knowledge users (the Wolf-Welsh Linkage Methodology or WWLM) with milestones in the evolution of an innovative computer-assisted instructional system called PLATO (Programming Logic for Advanced Teaching…

The videodisc, audiodisc, overlapping instruction, mapping, adaptive testing strategies, intricate instructional branching, and complex media selection models are common expectations for quality courseware today. A two team development structure, consisting of an instructional development team and a test development team, is proposed. This paper…

Discussion of intelligent computer assisted learning (CAL) systems considers both those that offer natural language communication to the user and those that are adaptive, generative, or self-improving. Current interest in student-built learning environments (exemplified by work with LOGO and PROLOG) is examined, and obstacles to future intelligent…

Arguing that an explicit representation of the problem-solving method of an expert system shell as abstract control knowledge provides a powerful foundation for learning, this paper describes the abstract control knowledge of the Heracles expert system shell for heuristic classification problems, and describes how the Odysseus apprenticeship…

A 10-week project conducted with 12 gifted 4th and 5th grade students (10 boys and 2 girls) examined the effectiveness of the Logo computer programming language as a tool for helping students understand some basic principles of physics. Three assumptions were tested: (1) motivated elementary school students can learn both turtle graphics and word…

Examines spatial concepts required by young children for the understanding and manipulation of turn commands in Logo, and reviews the literature on children's Logo learning and the psychological-cognitive development of spatial concepts. Geometric concepts, alternative frames of reference, and the use of Turtle graphics are also discussed. (39…

Describes a microcomputer-based system for diagnosing children's multiplication errors which incorporates the knowledge base of all known systematic multiplication errors, and utilizes a modular approach to cope with the program's complexity. Each module's function, how the programs interact, and the design of pupil-machine interaction are…
