With the advances in computational power, Internet access and speed, and graphical 3D reproductions possible on an "ordinary" home computer, and with the development of new software products that place the ability to create new digital content in the hands of "ordinary" people, everyone is beginning to see in virtual worlds emergent behaviors that…

When it comes to technologies like digital games, simulations, and social networking, teachers and students may find themselves at cross purposes. Often, students find that these technologies, so prevalent in their lives outside of school, are unwelcome in their classrooms. Many teachers can tell stories about the disruptive influence of video…

In Ramsay-curve item response theory (RC-IRT), the latent variable distribution is estimated simultaneously with the item parameters of a unidimensional item response model using marginal maximum likelihood estimation. This study evaluates RC-IRT for the three-parameter logistic (3PL) model with comparisons to the normal model and to the empirical…

Tutors have only limited time to support students. In this paper, we discuss a model that addresses the question of how to help students answer content-related questions. A small group of students is created, which consists of the student who asked the question and peers who should be able to answer it. Criteria used to compose the group are the…

Despite its image as an all-American city, downtown Peoria, Illinois, home of Bradley University, is also a place of strip clubs and violent crime. For undergraduates, it's a risky environment in which to conduct field research. Edward Lamoureux, an associate professor in Bradley's multimedia program, saw a better place in the virtual world Second…

Extreme-value statistics is often used to estimate so-called return values (actually related to quantiles) for environmental quantities like wind speed or wave height. A basic method for estimation is the method of block maxima which consists in partitioning observations in blocks, where maxima from each block could be considered independent.…

The technology is simple: Mobile technologies such as handheld computers and global positioning systems work in sync to create an alternate, hybrid world that mixes virtual characters with the actual physical environment. The result is a digital simulation that offers powerful game-playing opportunities and allows students to become more engaged…

This paper presents a research study carried out to support and structure virtual interaction among university students that may trigger collaborative knowledge construction in the Web, supported by a CSCL system called KnowCat. Three characteristics of the KnowCat system are relevant to our educational purpose: firstly, students can share and…

Over the past several decades, colleges and universities have moved away from the traditional chalk-and-talk lecture. Professors have experimented with a myriad of methods to engage students more fully. Some of the innovations that have been used have succeeded in improving student performance and satisfaction. In this paper we report the learning…

THE PROBLEM: This study investigated students' perceptions of the English Village Program at the Fong Shan Elementary School in Kaohsiung County, Taiwan. The main objectives of this research were to discover the fifth graders' motivation and attitudes toward (a) the simulated theme classrooms, (b) the native English-speaking teacher's instruction,…

In an attempt to prepare new graduate nurses to meet the demands of health care delivery systems, the use of computer-based clinical information systems that combine hands-on experience with computer based information systems was explored. Since the introduction of Electronic Medical Records (EMR) nearly two decades ago, the demand for nurses to…

Background: Numerous surveys, articles, ephemera and online information sources indicate that "Second Life" has been the predominant virtual world, for educational purposes, in UK universities for the latter half of the 2000s. However, the infrastructure required to operate "Second Life" presents a number of technical concerns…

The following article discusses an educational simulation created within Second Life (SL) in order to assist pre-service teachers (PSTs) in gaining more experience managing student behavior. The article discusses the development, implementation, and assessment of the simulation as well as student data on the feasibility of the approach in…

Dodeen (2004) studied the correlation between the item parameters of the three-parameter logistic model and two item fit statistics, and found some linear relationships (e.g., a positive correlation between item discrimination parameters and item fit statistics) that have the potential for influencing the work of practitioners who employ item…

The Internet usage has been increasing among persons in the worldwide. This situation highlights that the number of potential distance learners has been increasing in the Internet society. Besides, the terms and concepts of the Internet environments become to be spread out in this society like virtual reality. It is also possible to explain the…
