The Course Selection Matrix Chart helps student and counselor produce an objective ranking of available courses. The versatile and convenient five-step self-help method can accommodate comparison of up to seven courses and may be modified to compare items other than courses. (MSE)

Presents two papers commenting on previous published articles. Discusses formulas related to the determinants of sums and tests the formulas using some examples. Provides three special cases of the determinants of sums. (YP)

The technique of clustering facilitates constructivist investigation in counseling research and clinical counseling sessions. Clients can be helped to put difficult-to-verbalize feelings into words. Having clients collaborate in configuring the rich but chaotic data renders that data amenable to matrix analysis. Recently developed computer…

Describes methods for item construction for computer-based instruction (CBI). Use of a rational set generator (RSG) in presenting an adaptive sequence of items to the learner is described; a model matrix of a computer-based RSG is presented; concrete and defined concepts are discussed; and rule using is explained. (Four references) (LRW)

In this article an augmented matrix that represents a system of linear equations is called nice if a sequence of elementary row operations that reduces the matrix to row-echelon form, through matrix Gaussian elimination, does so by restricting all entries to integers in every step. Many instructors wish to use the example of matrix Gaussian…

In this note we consider a type of integral that is usually presented as an example in any textbook discussion of integration by parts. Invariably this integral is determined by integrating by parts twice and solving. We will present an alternate approach to this integral which makes use of the linearity of the integral, i.e., the fact that…

Describes a systematic approach to selecting instructional designs, discussing performance analysis, gaps, elements (inputs, conditions, process, outputs, consequences, feedback), matrices, changes in performance state (establishing, improving, maintaining, and extinguishing performance), intervention interference, and involving others in…

Explains zetetics which involve theories of research and epistemology and discusses its relevance to library science. Topics include library literacy, and the use of an information matrix to help library patrons understand what information they have and what they need to find. (Author/LRW)

Three analyses of /-t,d/ deletion are undertaken to investigate whether convergence with the matrix regional dialect has taken place in Los Angeles Chicano English. Two superficial analyses mistakenly find convergence. A third emic multivariate analysis finds no phonological convergence. (33 references) (Author/CK)

Discusses level 3 evaluation from Donald Kirkpatrick's Four Level Evaluation Model (level: 1-reaction; 2-learning; 3-behavior; 4-results) to measure training program performance. Highlights include an evaluation planning matrix; increasing evaluation data accuracy and reliability; data collection method selection; designing data collection…

Describes MATRIX-1, a small group activity that can be used to show interrelationships between various factors. Examples include values clarification; procedural phases; relationships among people; resource allocation; related concepts; and group decision making activities. Modifications to MATRIX-1 are discussed that allow for variations in…

In this paper, two classes of graphs of arbitrary order are described which contain unique Hamiltonian cycles. All the graphs have mean vertex degree greater than one quarter the order of the graph. The Hamiltonian cycles are detailed, their uniqueness proved and simple rules for the construction of the adjacency matrix of the graphs are given.…

This paper discusses a result of Li and Shen which proves the existence of a unique periodic solution for the differential equation x[dots above] + kx[dot above] + g(x,t) = [epsilon](t) where k is a constant; g is continuous, continuously differentiable with respect to x , and is periodic of period P in the variable t; [epsilon](t) is continuous…

A nontechnical exposition of graph theory is presented, followed by survey of the literature on applications of graph theory in research in education and related disciplines. Applications include order-theoretic studies of the dimensionality of data sets, the investigation of hierarchical structures in various domains, and cluster analysis.…

Discusses collection development policy as means to express and systematize guidelines for collection building that fulfill three basic functions: the referential, the generative, the rhetorical. Division of policy into subject categories, and use of "collection levels" to rank the collection and collecting effort for each subject are…
