School leaders are increasingly being asked, whether by rhetoric or policy, to measurably improve student achievement. The resultant need to assist school leaders in their ability to improve teaching and learning for all students in their schools led to the establishment of the National Institute of School Leadership's (NISL's) Executive…

Invited as a paper from E-Learn 2009 This study compared two programmes developed as a learning tool for students to practise basic laboratory procedures. One was a Flash simulation programme, the other a Second Life virtual reality programme. A cohort of 93 bioscience students participated in the between trial. A control group was used to…

The goal of this research was to predict from a recruit's responses to the Armed Services Vocational Aptitude Battery (ASVAB) items whether the recruit would pass the Armed Forces Qualification Test (AFQT). The data consisted of the responses (correct/incorrect) of 1,020 Navy recruits to 200 items of the ASVAB together with the scores of these…

Discusses motives behind development of teaching aids to introduce library science students to online searching, range of such aids the College of Librarianship Wales has developed, and describes a microcomputer package which comprises a computer assisted instruction module to familiarize students with DIALOG and an emulation which allows online…

Describes a kangaroo simulation which can be adapted for use with radio tracking activities for other animals. Outlines procedures and information to help implement the activity. Provides a map of Australia, calculations, and sample kangaroo movement data. (RT)

In practical applications of item response theory (IRT), item parameters are usually estimated first from a calibration sample. After treating these estimates as fixed and known, ability parameters are then estimated. However, the statistical inferences based on the estimated abilities can be misleading if the uncertainty of the item parameter…

Evaluation experiments have been essential in exploring home delivery of lectures for which users can experience campus lifestyle and distant learning through 3D virtual space. This paper discusses the necessity of virtual space for distant learners by examining the effects of virtual space. The authors have pursued the possibility of…

This article explores the simulation of four television quiz shows for students in China studying English as a foreign language (EFL). It discusses the adaptation and implementation of television quiz shows and how the students reacted to them.

As networking systems have become more complex and expensive, hands-on experiments based on networking simulation have become essential for teaching the key computer networking topics to students. The simulation approach is the most cost effective and highly useful because it provides a virtual environment for an assortment of desirable features…

In this study a business game is used as a vehicle for implementing decision support systems (DSS). Eighteen companies, consisting of ninety graduating M.B.A. students, participating in a business game were required to develop DSS and to report on the systems developed. Each of the eighteen companies developed a system of their own choosing,…

The kids in today's classrooms spend lots of time playing video games, surfing the net, listening to iPods, and text messaging on cell phones. Known as Digital Kids and the Net Generation, they have grown up surrounded by digital media of all types (Tapscott 1999). Because they are already knowledgeable, why not use digital technologies to capture…

Because of the increased popularity of computerized adaptive testing (CAT), many admissions tests, as well as certification and licensure examinations, have been transformed from their paper-and-pencil versions to computerized adaptive versions. A major difference between paper-and-pencil tests and CAT from an examinee's point of view is that in…

Immersive Education is a multimillion-dollar project devoted to build virtual-reality software exclusively for education within commercial and nonprofit fantasy spaces like Second Life. The project combines interactive three-dimensional graphics, Web cameras, Internet-based telephony, and other digital media. Some critics have complained that…

A person fit test based on the Lagrange multiplier test is presented for three item response theory models for polytomous items: the generalized partial credit model, the sequential model, and the graded response model. The test can also be used in the framework of multidimensional ability parameters. It is shown that the Lagrange multiplier…

An exercise is presented in which the kinetics of the irreversible "reaction" of pennies in the heads-up state to pennies in the tails-up state is simulated by a hands-on, Monte Carlo approach. In addition, the exercise incorporates a second simulation in which the irreversible "reaction" of dice with a red face uppermost to a blue face uppermost…
