Describes computer measurement of capacitor charge decay, change of fringe width with color, computer simulation of color mixing, Doppler effect/carrier waves, gravitational waves, microwave apparatus, computer simulation of Brownian motion, search coils and problems with the teaching of the relationships of velocity, frequency, and wavelength in…

Computer Adaptive Sequential Testing (CAST) is a test delivery model that combines features of the traditional conventional paper-and-pencil testing and item-based computerized adaptive testing (CAT). The basic structure of CAST is a panel composed of multiple testlets adaptively administered to examinees at different stages. Current applications…

Research during the past decade suggests that integrating computing technology in general, and mobile computers in particular, into the educational environment has positive effects. This is the first long-term study of high school Personal Digital Assistant use. It involved three-parts, 146 students during four years. Part one found that PDA use…

The purpose of this study was to compare and evaluate three online pretest item calibration/scaling methods in terms of item parameter recovery when the item responses to the pretest items in the pool would be sparse. The three methods considered were the marginal maximum likelihood estimate with one EM cycle (OEM) method, the marginal maximum…

This report presents the results of qualitative and quantitative analyses of how well the higher education system in Nevada will meet the challenges of the future of current trends and patterns continue. The report contains three parts that present the data analysis, the key issues the Nevada Board of Regents confronts, with possible responses to…

In a previous study (1998), how to evaluate whether adaptive testing data used for online calibration sufficiently fit the item response model used by C. Glas was studied. Three approaches were suggested, based on a Lagrange multiplier (LM) statistic, a Wald statistic, and a cumulative sum (CUMSUM) statistic respectively. For all these methods,…

A simulation study was conducted to explore the potential of state assessment scores to improve adjustments for nonparticipation (McLaughlin, Gallagher, and Stancavage, 2004). That study found that state assessment scores could potentially be more effective than demographic information in removing the bias related to absences. The present study…

This report describes a multidisciplinary project by members of Virginia Polytechnic Institute and State University's Departments of Geography and Computer Science, and College of Education, to develop computer-aided education software for introductory geography at the college and high school levels. GeoSim's goal was to produce major changes in…

This simulation allows students to experience colonial America during the days from the closing of the French and Indian War until the Declaration of Independence. It is designed to help students gain a knowledge of the historical period, an appreciation of the many cross-pressures that colonial citizens were subjected to, and a feeling for the…

This simulation allows students to learn about and participate in many of the aspects of ancient Roman life that have influenced present institutions and way of life. The phases of the unit include: (1) "Daily Life"; (2) "Forum of Roma"; (3) "Temple of Apollo"; (4) "Pax Romana"; (5) "History/Mystery:…

Every year the Supreme Court hears dozens of cases related to key constitutional issues. These cases can be used to teach enduring concepts in government and law. With this lesson plan, students learn about important concepts in Fourth Amendment law and stage a mock Supreme Court oral argument in small groups on a case decided in the 1999-2000…

The Community Access Through Technology Project (CATT) is developing and implementing virtual reality software that persons with disabilities can use to experience a physical location prior to visiting it in person. A virtual scenario of one physical location has been developed, implemented, and tested, and work is underway on two others. Using a…

This document contains the following papers on simulations and case studies from the SITE (Society for Information Technology & Teacher Education) 2002 conference: "3-D Virtual Classroom Technology" (Kimberly Arseneau Miller, Angela Glod); "Simulated Lesson Design Studios" (Willis Copeland); "Lights, Camera, Integration: Presentation Programs and…

This paper reports on efforts to design a computer-based instructional unit for 7th grade students that would not only address state standards but would also provide some groundwork for the students' subsequent formal study of algebra. SimCalc Mathworlds software was used to explore the same motion from different perspectives. The overall…

In modern society, a company's competitive advantage is directly related to its capacity for product development. This paper describes the use of a Model Integrated Factory to simulate product development business processes for the education of engineers. (WRM)
