Test equating is a statistical procedure for adjusting for test form differences in difficulty in a standardized assessment. Equating results are supposed to hold for a specified target population (Kolen & Brennan, 2004; von Davier, Holland, & Thayer, 2004) and to be (relatively) independent of the subpopulations from the target population (see…

Computer-based surgical training simulators are instrumental in skill-based training and performance measurement. However, to date, the educational employment of these tools lacks empirically founded insights and effective practical guidelines. This study examined surgical residents during computer-based simulator training of basic laparoscopic…

Two Monte Carlo simulations were performed to compare methods for estimating and testing hypotheses of quadratic effects in latent variable regression models. The methods considered in the current study were (a) a 2-stage moderated regression approach using latent variable scores, (b) an unconstrained product indicator approach, (c) a latent…

This study applies the learning curve method of measuring learning to participants of a computer-assisted business gaming simulation that includes a multiple-life-cycle feature. The study involved 249 participants. It verified the workability of the feature and estimated the participants' rate of learning at 17.4% for every doubling of experience.…

Researchers are increasingly using observational or nonrandomized data to estimate causal treatment effects. Essential to the production of high-quality evidence is the ability to reduce or minimize the confounding that frequently occurs in observational studies. When using the potential outcome framework to define causal treatment effects, one…

Project-based learning is undoubtedly one of the best instructional methods for developing students' broad learning capabilities, beyond teaching specific subject matter. However, experienced engineering teachers often tend to concentrate on merely teaching pupils the technical side of project work. This paper describes a programme aimed at…

Leading change is an essential skill for managers. Instructors in management education must not only teach theories on effectively leading change but also convince students of the necessity of developing their change leadership skills. Students may underestimate the difficulty of convincing others to work toward change; the authors developed the…

This paper discusses a comparative study of the effects of using a humanoid robot for introducing students to personal robotics. Even if a humanoid robot is one of the more complicated types of robots, comprehension was not an issue. The study highlighted the importance of using real hardware for teaching such complex subjects as opposed to…

Virtual worlds provide unique opportunities for instructors to promote, study, and evaluate student learning and comprehension. In this article, Victor Vergara, Thomas Caudell, Timothy Goldsmith, Panaiotis, and Dale Alverson explore the advantages of using virtual reality environments to create simulations for medical students. Virtual simulations…

This review of the theoretical framework for Mastery Learning Theory and Sense of Community theories is provided in conjunction with a review of the literature for mobile technology in relation to language learning. Although empirical research is minimal for mobile phone technology as an aid for language learning, the empirical research that…

Online virtual worlds are becoming important tools in foreign/second language instruction in view of the fact that they enhance learner motivation, promote autonomy and social presence in a 3D environment. Virtual worlds are a type of reality in which students can meet and communicate with other learners in the target language using text, voice or…

The "TOEFL iBT"® test presents test takers with tasks meant to simulate the tasks required of students in English-medium universities. Research establishing the validity argument for the test provides evidence for score interpretation and the use of the test for university admissions and placement. Now that the test has been operational…

Recent studies of learner interaction in virtual worlds have tended to select basic tasks involving open-ended communication. There is evidence that such tasks are supportive of language acquisition, however it may also be beneficial to consider more complex tasks. Research in task-based learning has identified features such as non-linguistic…

Studies considering whole-class use of computer simulations are limited, despite the increasing interest in this mode of use. The current study explored how a collection of computer simulations was integrated into both whole-class and small-group instructional settings during a high school chemistry unit on atomic structure. Participants included…

The introduction of new technologies in society has created a need for interactive contents that can make the most of the potential that technological advances offer. Serious games as educational games are such content: they can be defined as video games or interactive applications whose main purpose is to provide not only entertainment but also…
