Six control structures are used in teaching a college Fortran programing course: (1) simple sequences of instruction without any control statement, (2) IF-THEN selection, (3) IF-THEN-ELSE selection, (4) definite loop, (5) indefinite loop, and (6) generalized IF-THEN-ELSE case structure. Outlines, instead of flowcharts, are employed for algorithm…

As part of an ongoing program of research to identify the difficulties encountered by novice programmers and to develop teaching strategies to help them overcome these obstacles, researchers employed a scaffolded interview procedure with 20 high school students enrolled in the second semester of a year-long BASIC course. Investigators presented…

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)

Assessed the effectiveness of four instructional methods used in fostering computer literacy and in teaching programing skills in 22 primary classes. Four key instructional variables delineated in Direct Instruction Model research were manipulated across the four methodologies. List of instructional objectives, instructional design, results, and…

This 5-section report summarizes the results of a project concerned with how novices learn to become creative educational computer users. Based on a cognitive analysis of elementary programming statements in BASIC and calculator language into conceptual units, the project builds on previous research on learning BASIC programming. A general…

To learn more about the specific nature of the teaching and learning problems involved, researchers conducted a clinical study of 20 high school students enrolled a BASIC course. Investigators presented each student with a sequence of eight programming problems, ranging from easy to difficult. They asked questions to track student thinking and…

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…

This paper describes a Prolog execution model which serves as the uniform basis of textbook material, video-based teaching material, and an advanced graphical user interface for Prolog programmers. The model, based upon an augmented AND/OR tree representation of Prolog programs, uses an enriched "status box" in place of the traditional…

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…

A survey of over 700 Ontario secondary schools was conducted in 1987 and again in 1989 to determine the current status of computer programing pedagogy. Presents an overview of the computer education curriculum for grades 10-12 and results related to hardware utilization, choice of programing languages, availability of teacher and student…

Discusses software metrics and describes a study of graduate students in Hong Kong that evaluated the relevance of using software metrics as a means of assessing students' performance in programing. The use of four basic metrics to measure programing skill, complexity, programing style, and programing efficiency using Pascal is examined. (13…

A study involving 120 undergraduate students attending the University of St. Thomas in St. Paul (Minnesota) was undertaken to test the interactive effect of instructional strategy (structured versus constructed) with learner's prior domain knowledge in concept acquisition. Previous instructional design research on concept learning has focused on…

An experience in attempting to transform research into practice is described, with questions raised about the relationship between research and practice. The author begins by describing the two research traditions which exerted the most force on the design of the program. How the philosophy and findings of those traditions were interpreted and…

The pedagogical strategies of human tutors in problem solving domains are described and the possibility of incorporating these techniques into computerized tutors is examined. GIL (Graphical Instruction in LISP), an intelligent tutoring system for LISP programming, is compared to human tutors teaching the same material in order to identify how the…

This study addresses three questions: (1) whether sex is related to ability and interest in computers; (2) whether a relationship exists between the presence of a computer in the home and a child's ability and interest in computing; and (3) the combination of factors that account for students' perceptions of success in developing programming…
