Persistent conceptual bugs exist in how novices, from primary school to college age, program and understand programs. These bugs are not specific to a given programming language but appear to be language-independent. The three different classes of bugs are: (1) parallelism, the assumption that different lines in a program can be active at the same…

Designed for use by computer programming teachers, this booklet presents the concepts of structured programming and provides examples of how to implement this methodology, which provides a systematic way of organizing programs so that even large and complex programs are easier to understand and modify than unstructured programs. After a brief…

Intended as an aid in the selection of software techniques and tools, this document contains three sections: (1) a suggested methodology for the selection of validation, verification, and testing (VVT) techniques and tools; (2) summary matrices by development phase usage, a table of techniques and tools with associated keywords, and an…

In an attempt to specify in some canonical terms what many heuristic programs known as "expert systems" do, an analysis was made of ten rule-based systems. It was found that these programs proceed through easily identifiable phases of data abstraction, heuristic mapping onto a hierarchy of pre-enumerated solutions, and refinement within this…

This course is designed to prepare electronics personnel for further training in digital techniques, presenting need to know information that is basic to any maintenance course on digital equipment. It consists of seven study units: (1) binary arithmetic; (2) boolean algebra; (3) logic gates; (4) logic flip-flops; (5) nonlogic circuits; (6)…

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…

American society is moving from an industrial age to an electronic, information age, and during the next decade both individuals and industry will have to cope with this transition. Effectiveness in dealing with the impact of technology will depend upon the ability of individuals to address four issues: (1) preparing for increased work…

A look at computer assisted instruction at Penn State University. (HB)

This paper discusses the kinds of computer applications in relationship to the level of computer capabilities utilized and the educational benefits derived. (Author)

A simple computational model is used to predict the behavior of response time as a function of think time for different conditions of service loading. The economic implications are considered. (Author)

A description of how highly sophisticated, computerized robots can be used in the classroom. (HB)

Monte Carlo methods were used to investigate the robustness of techniques used in judging the magnitude of a sample correlation coefficient when observations are correlated. Empirical distributions of r, t, and Fisher's z were generated. A technique for controlling error rates in certain situations is suggested. (Author/BJG)
