Innovations in network and information technology have transformed traditional classroom lectures into new approaches that have given universities the opportunity to create a virtual laboratory. However, there is no systematic framework in existing approaches for the development of virtual laboratories. Further, developing a virtual laboratory…

Physical activity participation rates in the United States have been in steady decline for the last 25 years, so much so that 60% of youth ages 9-13 years get no physical activity outside of school. This state of inactivity indicates that promoting participation in physical activity at a young age is of importance. For the present study, a…

The move by training and educational institutions in Australia toward the use of multimedia to facilitate effective and cost effective training and professional development has grown at a substantial pace. This paper focuses on the impact of multimedia on the areas of training and professional development. Benefits of the technology are described,…

The development and preliminary evaluation of the Computerized Adaptive Testing System (CATSYS), a new testing package for IBM-compatible microcomputers, are described. CATSYS can be used to administer and score operational adaptive tests or to conduct on-line computer simulation studies. The package incorporates several innovative features,…

Computer games are very popular among children and adolescents. In this respect, they could be exploited by educational software designers to render educational software more attractive and motivating. However, it remains to be explored what the educational scope of educational software games is. In this paper, we explore several issues concerning…

This article discusses modern stereoscopic displays for geographic education, focusing on a large-format display--the GeoWall. To evaluate the potential of the GeoWall, geography instructors were asked to express their reactions to images viewed on the GeoWall during a focus group experiment. Instructors overwhelmingly supported using the GeoWall,…

Spatial visualization is a fundamental skill in technical graphics and engineering designs. From conventional multiview drawing to modern solid modeling using computer-aided design, visualization skills have always been essential for representing three-dimensional objects and assemblies. Researchers have developed various types of tests to measure…

Len Annetta, Marta Klesath, and Shawn Holmes describe how avatars in virtual learning environments (VLEs) can contribute to the learning experience by giving students a sense of social presence and investment in the learning community that may otherwise be difficult to access. VLEs have the potential to become the next generation of instructional…

Many credentialing agencies today are either administering their examinations by computer or are likely to be doing so in the coming years. Unfortunately, although several promising computer-based test designs are available, little is known about how well they function in examination settings. The goal of this study was to compare fixed-length…

"Computer Simulations of Salt Solubility" by Victor M. S. Gil provides an animated, visual interpretation of the different solubilities of related salts based on simple entropy changes associated with dissolution such as configurational disorder and thermal disorder. This animation can help improve students' conceptual understanding of…

Describes study that investigated teachers' criteria for the use of courseware packages in Dutch junior high school physics classes. The development of a courseware evaluation instrument is described; drill and practice, simulation, and tutorial courseware packages are evaluated; motivating elements are considered; and implications for the design…

This paper describes a computer model that simulates the way children develop the reasoning skills of transitive inference and the construction of ordered sets. The computer model begins from general operations, such as setting and removing goals, storing and retrieving information, comparing elements to find matches, reading premises, and giving…

The purpose of this study was to assess the effects of correlated dimensions and differential ability on one dimension on parameter estimation when using a two-dimensional item response theory model. Multidimensional analysis of simulated two-dimensional item response data fitting the M2PL model of M. D. Reckase (1985, 1986) was conducted using…

This report contains a theoretical model for describing the motion of a passenger car. The simulation program based on this model is used in conjunction with an advanced driving simulator and run in real time. The mathematical model is complete in the sense that the dynamics of the engine, transmission and steering system is described in some…

Comparisons are made between BILOG version 2.2 and LOGIST 5.0 version 2.5 in estimating the item parameters, traits, item characteristic functions, and test characteristic functions for the three-parameter logistic model. Speed and accuracy are reported for a number of 10, 20, and 40-item tests. (Author/GDC)
