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…

Four conference papers are reviewed in this introduction to a symposium. The first paper is by Clements and Merriman, who make a case for the reflection of Steinberg's information processing componential model of cognitive processes in the LOGO language and computational environment; present a series of experiments that attempted to tailor the…

Designed initially for use in college computer science courses, the model and computer-aided instructional environment (CAIE) described helps students develop algorithmic problem solving skills. Cognitive skills required are discussed, and implications for developing computer-based design environments in other disciplines are suggested by…

This study reports two experiments which indicate that the processes of providing subjects with insightful representations of example programs and guiding subjects through an "ideal" problem solving strategy facilitate learning. A production system model (GRAPES) has been developed that simulates problem-solving and learning in the…

Designed to focus attention on the design process in such computer science activities as information systems design, database design, and expert systems design, this paper examines three main phases of the design process: understanding the context of the problem, identifying the problem, and finding a solution. The processes that these phases…

This paper discusses two conflicting opinions on the role of computer education within the West German school curriculum, i.e., the opinion of the majority of the education ministers and administrators, who wish to see computer use distributed over as many school subjects as possible, and a minority of specialists in computer education who prefer…

A broad range of well-structured problems--embracing forms of diagnosis, catalog selection, and skeletal planning--are solved in expert computer systems by the method of heuristic classification. These programs have a characteristic inference structure that systematically relates data to a pre-enumerated set of solutions by abstraction, heuristic…

This paper discusses the overall design of the PIXIE Intelligent Tutoring System, and more specifically a series of recent enhancements. The original system has been implemented to involve three separate phases: the offline, or model generation phase; the online, or tutoring, phase; and the analysis phase. The offline phase, which is completed…

The We Do--They Do Model provides an evaluation methodology that service providers can use on a small scale to obtain data for themselves and for the over-all system. The model allows for complete assessment of ongoing program implementation and outcome. Three questions are used to organize evaluation activities: (1) Did staff (We) do what we said…

Describes an investigation which assessed predictive value of Iowa Test of Educational Development, Science Research Associates Inc.'s Computer Programming Aptitude Battery, and Wolfe Programming Aptitude Test for predicting secondary school students' success in computer science courses, to develop a prediction model, and to estimate mastery…

This report describes the procedures used to construct and validate the Standardized Test of Computer Literacy (STCL), a criterion-referenced instrument designed to assess students' computer literacy. Following a statement of the study problem and purpose, a description of the study methodology outlines the use of a 12-step model for development…

Six studies discussed in this paper compared error-specific or model-based remediation (MBR) with reteaching in algebra. MBR points out, and highlights as incorrect, errors specific to the student's solution before reteaching the correct procedures. Reteaching shows the student the correct procedure without addressing specific errors. Three of…

This paper provides an overview of the four major aspects of the PIXIE Intelligent Tutoring System: the field work undertaken to determine how teachers diagnose and remediate in introductory algebra; the set of experiments run to determine the relative effectiveness of Model-Based-Remediation (MBR) and Reteaching; systems work carried out to…

Developed to guide the research of the Educational Technology Center, a consortium based at Harvard Graduate School of Education, this report addresses the use of new information technologies to enrich, extend, and transform current instructional practice in science, mathematics, and computer education. A discussion of the basic elements required…

Describes a study of 38 students at Eastern Oregon State College which identified mathematics proficiency as the key student characteristic leading to successful completion of computer science courses, and developed a model that accounts for 82 percent of the variation in students' final grades in computer courses for use by advisers.
