The article discusses the use of computers to teacher college level mathematics. In particular, the Gaussian elimination procedure for solving a system of n linear equations in n unknowns, using a computer, is examined. (PK)

Presents ideas that are intended to convey new insights on familiar topics and to enhance pedagogy. The mathematical topics addressed are applications of transformations to numerical integration, the golden ratio, Cramer's rule, a counting problem, and the general form of the arithmetic-geometric mean inequality. (PK)

Described are procedures for multiplying matrices using Logo. Examples of computer programming are included. (RH)

Points out the benefits of students using LOGO with problems dealing with vectors and matrices. Provides examples of performing linear algebraic computations in LOGO. (ML)

Examines relationships between the two major components of computer simulations, the computer and participants; highlights major differences between computer-assisted, computer-based, and computer-controlled simulations; and describes three computer-assisted simulations to illustrate the interdependence of the major components. (MBR)

Describes experiments relating information to decision making. The experiments were developed to validate previously suggested conceptual model of information flow and its relation to decision making and to establish specific values for significant parameters involved. Background and summary of recent research and experimental design and research…

The use of systems analysis in transforming a graduate program in educational technology from a lecture-based system to a self-instructional one is described. Several operational research techniques are illustrated. A bibliography of 10 items is included. (CHC)

Construct organization was inferred from subjects' responses to a specially modified implication grid. Both developmental predictions and the validity of grid measures received excellent support from the analysis of children's theories of their peers as a function of their own age, sex and verbal intelligence.

Designed to determine whether (1) children of middle socioeconomic status (SES) learn matrix completion rules more rapidly than lower-SES children; (2) feedback influences rate of rule acquisition; (3) rule shifting influences rate of rule acquisition; (4) SES is associated with transfer of training; and (5) effectiveness of rule acquisition and…

Three methods of estimating a model of school effects are compared: ordinary least squares; an approach based on the analysis of covariance; and, a residualized input-output approach. Results are presented using a matrix algebra formulation, and advantages of the first two methods are considered. (Author/GK)

The Matrices and Order of Appearance subtests of a Piagetian test battery were administered to a sample of second-grade children on two occasions under two test conditions: standardized testing and a dialogue between child and examiner. Differences for test condition and time of testing were found. (JKS)

Examines issues of copyright clearance by British universities for digitizing published printed materials. Discusses types of digitization, pricing, contract language, "compliance culture," publishers' rights, terms of licenses, and developing a publishers'"code of practice," and proposes a matrix of uses and users to support…

Describes how the structure of hypermedia systems can be represented by a simple matrix which is the basis for applying standard techniques of network analysis, and demonstrates the potential influence of these techniques on learning processes or outcomes. Also discusses theoretical and practical implications for future hypermedia research. (AEF)

Presented is a method where a quadratic equation is solved and from its roots the eigenvalues and corresponding eigenvectors are determined immediately. Included are the proposition, the procedure, and comments. (KR)

Discussed is how a separable field extension can play a major role in many treatments of Galois theory. The technique of diagonalizing matrices is used. Included are the introduction, the proofs, theorems, and corollaries. (KR)
