We compared the performance of three heuristics with that of subjects on variants of a well-known combinatorial optimization task, the Traveling Salesperson Problem (TSP). The present task consisted of finding the shortest path through an array of points from one side of the array to the other. Like the standard TSP, the task is computationally…

Our standard secondary model of adding standardized educational components to passive students has outlived its worth. A more sculptural metaphor may be of assistance: the idea of removing that which is not essential, of finding and bringing forth the essence of those who come before us.

This article is the second in a series of pre-conference papers prepared for participants at AACRAO's Fifteenth Annual Strategic Enrollment Management Conference (SEM XV), held November 13-16, 2005 in Chicago, Illinois. This second article of the three-part series has sought to further define, delineate, and differentiate four broad orientations…

The information matrix for the parameters in a latent-variable model is bounded from above by the information that would obtain if the values of the latent variables could also be observed. The difference is the "missing information." This paper discusses the structure of the information matrix, and characterizes the degree to which…

Analysis of variance (ANOVA) was invented in the 1920s to partition variance of a single dependent variable into uncorrelated parts. Having uncorrelated parts makes the computations involved in ANOVA incredibly easier. This was important before computers were invented, when calculations were all done by hand, and also were done repeatedly to check…

The concept of the general linear model (GLM) is illustrated and how canonical correlation analysis is the GLM is explained, using a heuristic data set to demonstrate how canonical correlation analysis subsumes various multivariate and univariate methods. The paper shows how each of these analyses produces a synthetic variable, like the Yhat…

This paper illustrates how canonical correlation analysis can be employed to implement all the parametric tests that canonical methods subsume as special cases. The point is heuristic: all analyses are correlational, all apply weights to measured variables to create synthetic variables, and all yield effect sizes analogous to "r"…

This brief paper argues that structural analysis--an extended form of cognitive task analysis--demonstrates that both domain dependent and domain independent knowledge can be derived from specific content domains. It is noted that the major difference between the two is that lower order rules (specific knowledge) are derived directly from specific…

Reflects on the work of Jurgen Habermas to help develop an objective and subjective rhetoric that are not in isolation from each other. Finds communicative competence a challenging conception of rhetoric's humane purpose: namely, the formation of autonomous and responsible speakers, capable of participating fully in the discourse of a speech…

Defines heuristics as cognitive "rules of thumb" that can help problem solvers work more efficiently and effectively. Professors can use a heuristic model of problem solving to guide students in all disciplines through the steps of problem-solving. (SWM)

Proposes the Integral Nursing framework, which combines Wilber's All-Quadrant/All-Level model, a heuristic device to organize human experience, and the Spiral Dynamics model of human development organized around value memes or cultural units of information. Includes commentary by Beth L. Rodgers. (Contains 17 references.) (JOW)

Discusses how the conceptual apparatus and modus operandi of games theory provides a research heuristic for understanding the strategic possibilities inherent in typical classroom situations in which the interests of students and teachers are partially concurrent and partly in conflict. Also discusses the preconditions for contracts between…

Argues that business communication is not improving, despite a deluge of advice. Suggests that change is made more difficult by hard to remember rules and directives that are couched in technical jargon. Offers an alternative heuristic focusing on context. (JAD)

A series of experiments involving more than 40 mechanical engineers and engineering students with different levels of expertise examined strategies, competence, and style of the designers in problem-solving behavior. A model is proposed that explains differences in designing as an interaction of domain-specific and heuristic competence. (SLD)

Provides an analysis of the hurtful power of words, the history of marginalized and oppressed peoples finding their voice, and the origins and current social contexts surrounding the words "harlot,""patterns," and a vocabulary that suggests all things "other." (PA)
