Uses computer simulation to study the effects on parametric and nonparametric statistical tests when assumptions of normality and homogeneity of variance are violated. Results reveal that nonparametric methods are not always acceptable substitutes for parametric methods in research studies when parametric assumptions are not satisfied. (SLD)

Discussion of computer-based simulations for business focuses on adding transparency through system dynamics techniques. Describes an experiment that evaluated the relevance and the effects of providing structural transparency to users of business simulators and suggests further research. (Contains 51 references.)

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…

Some game users have contended that students can be successful in games even if they "know little" about the rules and the underlying business theories driving them. Thus, if teams are uninvolved, it is possible that successful game play may not impart the learning typically found in experiential exercises nor that designed into games by their…

Distance learning in advanced military education can assist officers around the world to become more skilled and qualified for future challenges. Through well-chosen technology, the efficiency of distance-learning can be improved significantly. In this paper we present the architecture of Advanced Military Education-Distance Learning (AME-DL)…

Many students perform extraction experiments without connecting relevant molecular features to corresponding macroscopic features. Two versions of an Organic Extraction Simulation, one with text "captions" and the other with "narration" accompanying the animation, were developed based on a cognitive view of multimedia learning.…

Understanding the concept of the sampling distribution of a statistic is essential for the understanding of inferential procedures. Unfortunately, this topic proves to be a stumbling block for students in introductory statistics classes. In efforts to aid students in their understanding of this concept, alternatives to a lecture-based mode of…

Especially in vocational education, attention should be paid not only to the use of new technological solutions but also to collaborative learning and cooperative working methods in order to develop students' skills for their future jobs. This study involves a design experiment including the design process of a new game environment, description of…

Technology-based instruction represents a new recent pedagogical paradigm that is rooted in the realization that new generations are much more comfortable with, and excited about, new technologies. The rapid technological advancement over the past decade has fueled an enormous demand for the integration of modern networking, informational and…

This article illustrates the utility of using virtual environments to transform social interaction via behavior and context, with the goal of improving learning in digital environments. We first describe the technology and theories behind virtual environments and then report data from 4 empirical studies. In Experiment 1, we demonstrated that…

Clinical research in expressive therapies, psychodrama in particular, offer education researchers and software designers descriptive analyses and evidence-based impact studies on attitudinal shifts and enhanced problem solving abilities for patients and students who participate in psychodrama role-play. Gaming environments and virtual worlds that…

Purpose: The purpose of this paper is to evaluate learners' attitudes to the use of simulation-based e-learning as part of workplace learning when socially situated interaction and blended learning are specifically included in the instructional design. Design/methodology/approach: Responses to a survey questionnaire of 298 sales personnel were…

This article presents a new algorithm for computerized adaptive testing (CAT) when content constraints are present. The algorithm is based on shadow CAT methodology to meet content constraints but applies Monte Carlo methods and provides the following advantages over shadow CAT: (a) lower maximum item exposure rates, (b) higher utilization of the…

Purpose: The purposes of this study were (a) to identify cognitive abilities and other factors related to successful completion of training for computer-based tasks that simulated real jobs and (b) to create a brief assessment battery useful in assessing older adults for these kinds of jobs. Design and Methods: Participants from three age groups…

Computer-based virtual patients (VPs) are an emerging medium for medical education that addresses barriers faced by geriatrics educators. Research has shown VPs to be as effective in changing knowledge and behavior as more traditional forms of teaching. This paper presents a descriptive study of the development of the University of Iowa's…
