This study examined school factors related to the learning style preferences of gifted Korean American students. The "Learning Styles Inventory-III" ("LSI"; Renzulli, Rizza, & Smith, 2002) and the "Ethnic Orientation Scale" ("EOS") were administered to 407 Korean American students in 30 schools. A…

Game-based assignments typically form an integral component of computer programming courses. The effectiveness of the assignments in motivating students to carry out repetitive programming tasks is somewhat limited since their outcomes are invariably limited to a simple win or loss scenario. Accordingly, this paper develops a simulation…

An inexpensive and equipment free approach to teaching the technical aspects of DNA sequencing. The activity described requires an instructor with a familiarity of DNA sequencing technology but provides a straight forward method of teaching the technical aspects of sequencing in the absence of expensive sequencing equipment. The final sequence…

This paper presents and tests a general model to predict emergent exchange patterns and power differences in reciprocal exchange networks when individual actors follow the norm of reciprocity. With an interesting qualification, the experimental results reported here support the power-dependence approach (Emerson 1972a, b): those who acquire the…

A simulation of the foreign policy decision-making process, as described in this article, can assist an instructor in linking students' abstract understanding of complex political events, circumstances, and decision making to the real-world interplay of the multiple factors involved in decision making. It is this type of active learning that helps…

This study proposes an innovative solution to the problem of multiobjective engineering design optimization by integrating desktop VR with genetic computing. Although, this study considers the case of construction design as an example to illustrate the framework, this method can very much be extended to other engineering design problems as well.…

Computerized adaptive testing (CAT) is a mode of testing which enables more efficient and accurate recovery of one or more latent traits. Traditionally, CAT is built upon Item Response Theory (IRT) models that assume unidimensionality. However, the problem of how to build CAT upon latent class models (LCM) has not been investigated until recently,…

This article explores the relationship between users' interpretations of a new technology and failure of organizational change. I suggest that people form interpretations of a new technology not only based on their conversations with others, but also through their use of technology's material features directly. Through qualitative and quantitative…

Virtual worlds are becoming increasingly sophisticated, showing potential as an effective platform for a variety of collaborative activities, including learning. This study examines students' intentions to use the virtual world Second Life (SL) for education, and explores factors associated with their intentions. Based on the Technology Acceptance…

Much recent psychometric literature has focused on cognitive diagnosis models (CDMs), a promising class of instruments used to measure the strengths and weaknesses of examinees. This article introduces a genetic algorithm to perform automated test assembly alongside CDMs. The algorithm is flexible in that it can be applied whether the goal is to…

This paper presents the results of a simulation exercise designed to explore and understand the implications of trying to survive in a marginal and poverty-stricken African community. The aim of the simulation was to create an approximation of a community involved in an income-generating project, akin to a Public Works Programme. This project…

This study implements a scale purification procedure onto the standard MIMIC method for differential item functioning (DIF) detection and assesses its performance through a series of simulations. It is found that the MIMIC method with scale purification (denoted as M-SP) outperforms the standard MIMIC method (denoted as M-ST) in controlling…

Purpose: The purpose of this paper is to provide description and an analysis of two worlds colliding where real-world roles or ideas play out in a virtual dimension. Inhabited by digital natives, the virtual world in a learning organization is a journey back to the future of microworlds where the only limitation is one's imagination.…

Our research explores a virtual reality application based on Web camera (Webcam) input-interface. The interface can replace with the mouse to control direction intention of a user by the method of frame difference. We divide a frame into nine grids from Webcam and make use of the background registration to compute the moving object. In order to…

Counselling and psychotherapy has been influenced by technology for over 50 years. During this time, the rate at which ways that technology of one kind or another can assist therapists and counsellors has seemed to increase exponentially. This paper introduces and summarises contributions to the subject of technological enhancements or extensions…
