This paper describes an empirical study that investigated the knowledge that Computer Science students have about the extent of their own previous learning. The study compared self-generated estimates of performance with actual performance on a data structures quiz taken by undergraduate students in courses requiring data structures as a…

Nondeterminism is an essential concept in mathematics and one of the important concepts in computer science. It is also among the most abstract ones. Thus, many students find it difficult to cope with. In this article, we describe some didactic considerations, which guided the development of a "Computational Models" course for high school…

This paper examines how Team Learning allows students to express themselves through their work. I define expression to include taking ownership of one's work, i.e. working through self-motivation rather than through the dictates of a teacher, and participating in a community of workers. This participation includes working with colleagues on…

A collaboration between three higher education institutions in Ireland and two European partners has resulted in the design and development of reusable learning objects for undergraduate programming students that would assist in their learning. This international project conducted extensive research of over 600 students' examination scripts in…

In this paper, two emerging learning and teaching methods have been studied: collaboration in concert with algorithm visualization. When visualizations have been employed in collaborative learning, collaboration introduces new challenges for the visualization tools. In addition, new theories are needed to guide the development and research of the…

Describes an enrollment projection approach that can easily show the complete dynamics of institutional enrollment change and can involve upper management in the development and understanding of important assumptions underlying the projection activity. (Author/MLF)

Designed to assist teachers and administrators approaching the subject of computers for the first time to acquire a feel for computer terminology, this document presents a computer term glossary on three levels. (1) The terms most frequently used, called a "basic vocabulary," are presented first in three paragraphs which explain their meanings:…

This glossary contains brief definitions of more than 550 special or technical terms used in scientific, technical, and social science research. Entries include various kinds of statistical measures, research variables, types of research tests, and research methodologies. Some computer terminology is also included. The glossary includes both…

This paper discusses and provides some preliminary data on errors in APL programming. Data were obtained by analyzing listings of 148 complete and partial APL sessions collected from student terminal rooms at the University of Alberta. Frequencies of errors for the various error messages are tabulated. The data, however, are limited because they…

Article describes the results of the evaluation of the Manitoba Schools Computer Network. (HB)

A model is described to suggest how the visual system may keep track of perceived objects as their images move on the retina. (Author)

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…

The development and testing of the Browsing On-line With Selective Retrieval (BROWSER) text retrieval system allowing a natural language query statement and providing on-line browsing capabilities through an IBM 2260 display terminal is described. The prototype system contains data bases of 25,000 German language patent abstracts, 9,000 English…

Several algorithms were investigated which would allow a user to interact with an automatic document retrieval system by requesting relevance judgments on selected sets of documents. Two viewpoints were taken in evaluation. One measured the movement of queries toward the optimum query as defined by Rocchio; the other measured the retrieval…
