We contrast 2 theories within whose context problems are conceptualized and data interpreted. By traditional linear theory, a dependent variable is the sum of main-effect and interaction terms. By dimensional theory, independent variables yield values on internal dimensions that in turn determine performance. We frame our arguments within an…

Reports a case study of thirteen college students engaging in a role-play activity of a Maui legend in a virtual reality environment. Immersed in the authentic cultural environment, the students not only interacted with the environment and each other, but recreated the legend based on their interpretation of the culture. (CAK)

Developed a simple computer program for the in-class simulation of the repeated prisoner's dilemma game with student-designed strategies. Describes the basic features of the software. Presents two examples using the program to teach the problems of cooperation among profit-maximizing agents. (JEH)

To become more skilled as pedestrians, children need to acquire a view of the traffic environment as one in which road users are active agents with different intentions and objectives. This paper describes a simulation study designed to explore children's understanding of drivers' intentions. It also investigated the effect of training children's…

Student participants (N = 316) viewed a videotaped simulated case involving a woman who had entered a self-defense plea in the shooting death of her abusive husband. As successful claims of self-defense rest on the portrayal of a defendant who has responded reasonably to his/her situation, the implications of various forms of expert testimony in…

Creating a forum for conflict management students to conceptualize and implement collaborative negotiation techniques can be difficult to manage during classroom time. A computer-based simulation assigned in conjunction with in-class activities offers three distinct advantages for students who are beginning negotiators: (1) classroom time may be…

Games like "Civilization III," a strategy game that allows players to create civilizations that stand the test of time, are attracting increasing attention in the educational community for their potential to support learning. A recent article in BBC news observed that "using "Civilisation III" to teach students about history showed that it could…

Several competing theories of short-term memory can explain serial recall performance at a quantitative level. However, most theories to date have not been applied to the accompanying pattern of response latencies, thus ignoring a rich and highly diagnostic aspect of performance. This article explores and tests the error latency predictions of…

This paper is a response to Paul Meara's (2005) critique of the Lexical Frequency Profile (LFP). Using simulated data, he challenges the claim that LFP is a sensitive and reliable tool for assessing vocabulary use in L2 speakers. In my response to his paper, I discuss the nature of lexical competence, in light of which LFP results should be…

One can develop a family and consumer sciences (FCS) course that teaches character education, and allows students to experience the good feelings that come from helping others through The Kindness Company. The Kindness Company is a simulated company that produces items for donation to local charitable organizations. Students get management…

This paper presents a row-column (RC) association model in which the estimated row and column scores are forced to be in agreement with a priori specified ordering. Two efficient algorithms for finding the order-restricted maximum likelihood (ML) estimates are proposed and their reliability under different degrees of association is investigated by…

The normal theory based maximum likelihood procedure is widely used in structural equation modeling. Three alternatives are: the normal theory based generalized least squares, the normal theory based iteratively reweighted least squares, and the asymptotically distribution-free procedure. When data are normally distributed and the model structure…

The purpose of the present study was to examine the effectiveness of most to least prompting on teaching pedestrian skills to individuals with developmental disabilities. Five individuals with developmental disabilities were taught three different pedestrian skills, all related to crossing the streets, using simulation activities on a road model…

D. N. Lee (1976) described a braking strategy based on optical expansion in which the driver brakes so that the target's time-to-contact declines around a constant slope in the range -0.5 less than or equal to tau less than 0. The present results from a series of braking simulations confirm and extend earlier reports (E. H. Yilmaz & W. H. Warren,…

This simulation study compared maximum likelihood (ML) estimation with weighted least squares means and variance adjusted (WLSMV) estimation. The study was based on confirmatory factor analyses with 1, 2, 4, and 8 factors, based on 250, 500, 750, and 1,000 cases, and on 5, 10, 20, and 40 variables with 2, 3, 4, 5, and 6 categories. There was no…
