In item response theory (IRT) modeling, the item parameter error covariance matrix plays a critical role in statistical inference procedures. When item parameters are estimated using the EM algorithm, the parameter error covariance matrix is not an automatic by-product of item calibration. Cai proposed the use of Supplemented EM algorithm for…

Instructional simulation had major difficulties in the past for offering limited possibilities in practice and learning. This article proposes a link between instructional simulation and Web 2.0 technologies. More exactly, I present the design of the Virtual Olympic Games Framework (VOGF), as a significant demonstration of how interactivity in…

The current study evaluated the accuracy of the Structured Interview of Reported Symptoms, Second Edition (SIRS-2) in a criterion-group study using a sample of forensic psychiatric patients and a community simulation sample, comparing it to the original SIRS and to results published in the SIRS-2 manual. The SIRS-2 yielded an impressive…

Students are required to choose courses they are interested in for the coming semester. Due to restrictions, including lack of sufficient resources and overheads of running several courses, some universities might not offer all of a student's desirable courses. Universities must know every student's demands for every course prior to each semester…

The training of tactical decision making increasingly occurs through serious computer games. A challenging aspect of designing such games is the modelling of human emotions. Two studies were performed to investigate the relation between fidelity and human emotion recognition in virtual human characters. Study 1 compared five versions of a virtual…

Immersive 3D worlds can be designed to effectively engage students in peer-to-peer collaborative learning activities, supported by scientific visualization, to help with understanding complex concepts associated with learning science, technology, engineering, and mathematics (STEM). Previous research studies have shown STEM learning benefits…

Education planning provides the policy maker and the decision maker a logical framework in which to develop and implement education policy. At the international level, education planning is often confounded by both internal and external complexities, making the development of education policy difficult. This research presents a discrete event…

Rural Kentucky residents suffer twice as many fire residential deaths than the national average. Fire prevention programs are primarily aimed at elementary school children however these children do not make the decisions nor take the precautions necessary to alter these conditions; their adult parents do. There is little research into the…

Developmental score scales represent the performance of students along a continuum, where as students learn more they move higher along that continuum. Unidimensional item response theory (UIRT) vertical scaling has become a commonly used method to create developmental score scales. Research has shown that UIRT vertical scaling methods can be…

It is not sufficient to just make changes in a nursing curriculum without a plan to evaluate the impact on program outcomes. This study sought to determine the outcomes of teaching the nursing process to Foundation of Nursing students in an Associate Degree Nursing program using a factorial design study. Four groups of students were taught the…

This chapter presents a case study of an online ethnography which examines the Romanian Community of Ireland forum. Apart from highlighting the main challenges and advantages of engaging with an ethnographic methodology online, this chapter also showcases the key findings emerging in relation to the meanings which members of this community…

The United States Air Force (USAF) trains C-130H Loadmaster students at Little Rock Air Force Base (AFB) through a civilian contract. The Aircrew Training System (ATS) contractor utilizes a Fuselage Trainer (FuT) to provide scenarios for the Loadmaster students to practice loading and unloading a simulated aircraft. The problem was the USAF does…

Two alternative technologies forming the basis of computer-mediated teacher preparation systems are compared and contrasted regarding implementation, operation, and assessment considerations. The role-playing system in Second Life is shown to have the unique characteristic of developing a co-constructed pedagogical identity, while the flight…

Technology permeates every aspect of daily life, from the sensors that control the traffic signals to the cameras that allow real-time video chats with family around the world. At times, technology may make life easier, faster, and more productive. However, does technology do the same in schools and classrooms? Will the benefits of technology…

Although Discrete-trial Teaching (DTT) is effective in teaching a many skills to children with autism, its proper implementation requires rigorous staff training. This study used an interactive computer simulation program ("DTkid") to teach staff relevant DTT skills. Participants (N = 12) completed two sets of pre-tests either once (n = 7) or…
