Evaluated the use of Mallow's C(p) and Wherry's adjusted R squared (R. Wherry, 1931) statistics to select a final model from a pool of model solutions using computer generated data. Neither statistic identified the underlying regression model any better than, and usually less well than, the stepwise selection method, which itself was poor for…

Using Excel, an interactive program is designed to simulate the Solow and endogenous growth models to facilitate the understanding of these models for students of growth theory and macroeconomics.

Glaciers are an excellent subject for elementary social studies classes. Their effects are easy for students to model with inexpensive teaching supplies, such as sand and ice. Students can conduct research nationally with virtual field trips or locally with real field trips. The models and research can be used as starting point for a discussion of…

Purpose: The purpose of this paper is to consider how simulations are increasingly used in training programs for the development of skills such as leadership. However, the requirements of leadership development go beyond the development of task specific procedural knowledge or expertise that simulations have typically been used to develop.…

Used computer simulation methods to examine the sensitivity of model fit criteria to misspecification of the first-level error structure in two-level models of change and to examine the impact of misspecification estimates on the variance parameters, estimates of the fixed effects, and tests of the fixed effects. Discusses problems caused by…

Develops a cultural transmission model with the following variables: worker entry and exit rate, organization growth rate, recruiting selectivity, socialization intensity, and the rate that socialization decays if not reinforced. A computer simulation of the model found that cultural systems in organizations are highly robust and reach equilibrium…

System Dynamics is a well formulated methodology for analyzing the components of a system including cause-effect relationships and their underlying mathematics and logic, time delays, and feedback loops. It began in the business and manufacturing world, but is now affecting education and many other disciplines. Having inspired by successful policy…

This paper provides qualitative student-centered research from an online Research Methodology course taught partly within the immersive, 3-D environment of Second Life with fifty-eight graduate psychology students for the purpose of suggesting a constructivist-based instruction model for immersive environments. A qualitative method approach was…

The Feature Integration Theory of visual search proposed by A. M. Treisman and others (1980, 1986) is reviewed, and a modified Guided Search theory is presented in which the parallel stage guides the serial stage as it chooses display elements to process. A computer simulation illustrates the theory. (SLD)

The parallel distributed processing model of visual word recognition in reading developed by Seidenberg and McClelland (1989) is extended through simulation. A response by Seidenberg and McClelland recognizes merits of the expanded model and outlines requirements for supplanting their original model. (SLD)

A discipline in which scientists seek to simulate and synthesize lifelike behaviors within computers, chemical mixtures, and other media is discussed. A computer program with self-replicating digital "organisms" that evolve as they compete for computer time and memory is described. (KR)

Coordination is a key issue in the design of organizational structures and processes. In this article, the authors propose a body of concepts that support the modeling and computer simulation of organizational processes and organizational coordination. Three aspect models are described that highlight different coordination aspects, and future…

Describes the developmental process used to visualize the calcium ATPase enzyme of the sarcoplasmic reticulum which involves evaluating scientific information, consulting scientists, model making, storyboarding, and creating and editing in a computer medium. (Author/CCM)

SUSTAIN (Supervised and Unsupervised STratified Adaptive Incremental Network) is a model of how humans learn categories from examples. SUSTAIN initially assumes a simple category structure. If simple solutions prove inadequate and SUSTAIN is confronted with a surprising event (e.g., it is told that a bat is a mammal instead of a bird), SUSTAIN…

It began in the business and manufacturing world, but is now affecting education and many other disciplines. Having inspired by successful policy…
