Elsom-Cook, Mark T.; O'Malley, Claire E. – Computers and Education, 1990
Describes ECAL (extended computer-assisted learning) which was designed to incorporate artificial intelligence ideas to extend traditional CAL tools. Intelligent tutoring systems are discussed; authoring tasks in CAL and intelligent computer-assisted instruction (ICAI) are described; and the general architecture of the system is explained. (8…

Harter, Stephen P. – Journal of the American Society for Information Science, 1990
Introduces a new methodology for studying the effects of term selection and postings overlap on retrieval, under the assumption that pooling results for several searchers or questions may obscure important relationships. Based on the findings of a case study, several tentative conclusions and hypotheses, are posited and suggestions for future…

Tenenhaus, Michel – Psychometrika, 1988
Canonical analysis of two convex polyhedral cones involves looking for two vectors whose square cosine is a maximum. New results about the properties of the optimal solution to this problem are presented. The convergence of an alternating least squares algorithm and properties of limits of calculated sequences are discussed. (SLD)

Kaur, Berinderjeet; Sharon, Boey Huey Peng – Focus on Learning Problems in Mathematics, 1994
An algebra test administered to (n=18) first-year college students found a disregard for negative numbers, ineffective use of counterexamples, misapplication of rules, and a lack of a good grasp of relevant mathematical terminology. (12 references) (MKR)

Gray, John S. – Journal of Computing in Higher Education, 1994
A detailed analysis and computer-based solution to a puzzle addressing the arrangement of dominoes on a grid is presented. The problem is one used in a college-level data structures or algorithms course. The solution uses backtracking to generate all possible answers. Details of the use of backtracking and techniques for mapping abstract problems…

Al-Hawamdeh, Suliman; And Others – Online Review, 1991
Describes a project at the University of Sheffield that is investigating the use of nearest-neighbor retrieval algorithms for full-text searching. Nearest-neighbor searching is compared with Boolean retrieval and hypertext, and an experimental text retrieval system called INSTRUCT (Interactive System for Teaching Retrieval Using Computational…

Stencel, John E. – Journal of College Science Teaching, 1992
Explains how a simple three-step algorithm can aid college students in solving synapse transmission problems. Reports that all of the students did not completely understand the algorithm. However, many learn a simple working model of synaptic transmission and understand why an impulse will pass across a synapse quantitatively. Students also see…

Donohoe, L. Joyce – AMATYC Review, 1992
Presents a public-key cryptosystem application to introduce students to several topics in discrete mathematics. A computer algorithms using recursive methods is presented to solve a problem in which one person wants to send a coded message to a second person while keeping the message secret from a third person.

Henriksen, Melvin, Ed.; Wagon, Stan, Ed. – American Mathematical Monthly, 1991
The discrete mathematics topics of trees and computational complexity are implemented in a simple reliability program which illustrates the process advantages of the PASCAL programing language. The discussion focuses on the impact that reliability research can provide in assessment of the risks found in complex technological ventures. (Author/JJK)

Paice, Chris D. – Information Processing and Management, 1991
Proposes that topic representations should consist of excerpts from domain thesaurus, generated by spreading activation technique. Algorithm for generating excerpts is outlined and exemplified, and problem of assessing resemblance between two excerpts is discussed. Whether existing thesauri are adequate for this purpose is questioned, and ideas…

Wong, S. K. M.; And Others – Journal of the American Society for Information Science, 1991
Discussion of user queries in information retrieval highlights the experimental evaluation of an adaptive linear model that constructs improved query vectors from user preference judgments on a sample set of documents. The performance of this method is compared with that of standard relevance feedback techniques. (28 references) (LRW)
