Fundamental concepts and definitions of electronic learning (eLearning) continue to emerge, and theories of eLearning that have been advanced thus far cover an array of academic perspectives including training and education, learning and knowledge, and technology and applications to specific market segments. Any study of the effectiveness and…

This article explores the potential learning benefits of three-dimensional (3-D) virtual learning environments (VLEs). Drawing on published research spanning two decades, it identifies a set of unique characteristics of 3-D VLEs, which includes aspects of their representational fidelity and aspects of the learner-computer interactivity they…

Educational computer games provide an environment in which interactions among students, teachers, and texts differ non-trivially from those of the traditional classroom. In order to build and research computer games effectively, it is important to provide a theoretical background that adequately describes and explains learning and interactions in…

The ability to plan and execute projects is a fundamental skill required among managers and business school graduates. In the opening phase of a project, the project team makes decisions about the relative priority of project time, cost, and performance objectives, oftentimes without complete information about customer and stakeholder…

[Slides] presented at the American Educational Research Association (AERA) Conference in New York in March 2008. This presentation explores what cues are used as a deciding factor in essay scoring by the essay grader.

Behavioral and neurophysiological evidence suggest that attention-deficit hyperactivity disorder (ADHD) is characterized by the impact of abnormal reward prediction error signals carried by the midbrain dopamine system on frontal brain areas that implement cognitive control. To investigate this issue, we recorded the event-related brain potential…

In this paper we describe and discuss simple, inexpensive optical experiments used to simulate x-ray and electron diffraction according to the Debye-Scherrer theory. The experiment can be used to address, at the high school level, important subjects related to fundamental quantum and solid-state physics.

The purpose of this study was to investigate the influence of game-like activities on adult learning during a computer-based simulation. This research also studied the use of visual metaphors as graphic organizers to help make the underlying science principles explicit without interfering with the interactive nature of the simulation. A total of…

In 4 studies, the authors examined the hypothesis that the structure of the informational environment makes small samples more informative than large ones for drawing inferences about population correlations. The specific purpose of the studies was to test predictions arising from the signal detection simulations of R. B. Anderson, M. E. Doherty,…

The traditional master of business administration (MBA) capstone strategy course is intended to integrate the prior course work of the MBA program but is doing this less and less well in today's high-velocity and complex business environment. The traditional strategy course structures, emphasizing formulation-implementation and the…

Objective: Adolescent mental illness stigma-related factors may contribute to adolescent standardized patients' (ASP) discomfort with simulations of psychiatric conditions/adverse psychosocial experiences. Paradoxically, however, ASP involvement may provide a stigma-reduction strategy. This article reports an investigation of this hypothetical…

Two studies, an experimental category learning task and a computational simulation, examined how sequencing training instances to maximize comparison and memory affects category learning. In Study 1, 2-year-old children learned color categories with three training conditions that varied in how categories were distributed throughout training and…

Rosenthal and Rubin introduced a general effect size index, r[subscript equivalent], for use in meta-analyses of two-group experiments; it employs p values from reports of the original studies to determine an equivalent t test and the corresponding point-biserial correlation coefficient. The present investigation used Monte Carlo-simulated…

This article reports the findings of a research project that saw researchers from interaction design and drama education come together with a group of eleven and twelve year olds to investigate the current and future complementarity of computers and live classroom drama. The project was part of a pilot feasibility study commissioned by the…

A simple model of the random Brownian walk of a spherical mesoscopic particle in viscous liquids is proposed. The model can be solved analytically and simulated numerically. The analytic solution gives the known Einstein-Smoluchowski diffusion law r[superscript 2] = 2Dt, where the diffusion constant D is expressed by the mass and geometry of a…
