Opinion polls in multiple countries recount a grim story, that people from Western and Muslim-majority countries regard one another as arrogant, intolerant, and violent, and that attitudes are not improving. Student exchange programs, which were widely expanded after World War II and during the Cold War, have become a vital component of public…

Background: In order to measure the proficiency of person populations in various domains, large-scale assessments often use marginal maximum likelihood IRT models where person proficiency is modelled as a random variable. Thus, the model does not provide proficiency estimates for any single person. A popular approach to derive these proficiency…

The aim of this paper is to provide an introduction of new imputation algorithms for estimating missing values from official statistics in larger data sets of data pre-processing, or outliers. The goal is to propose a new algorithm called IRMI (iterative robust model-based imputation). This algorithm is able to deal with all challenges like…

This article describes the competency-based approach to e-learning education that utilizes remote access to the laboratory equipment. The main focus of the paper is the structure and design of the e-learning system used in the Southern Federal University (Russia). The article discusses the related pedagogical strategies and presents system's…

Advanced three-dimensional virtual environment technology, similar to that used by the film and computer games industry, can allow educational developers to rapidly create realistic online virtual environments. This technology has been used to generate a range of interactive Virtual Reality (VR) learning environments across a spectrum of…

Publication selection bias is a serious challenge to the integrity of all empirical sciences. We derive meta-regression approximations to reduce this bias. Our approach employs Taylor polynomial approximations to the conditional mean of a truncated distribution. A quadratic approximation without a linear term, precision-effect estimate with…

Lean six sigma is a management methodology that firms can employ to achieve substantial improvement in supply chain performance. However, few pedagogical exercises facilitate students' use of a comprehensive set of lean six sigma principles within a supply chain context. We describe the Airplane Supply Chain Simulation that helps students…

Online educational instruction has become more prevalent in American and international educational institutions and is increasingly the chosen format for many academic programs. The use of web conferencing, virtual classrooms, and computer-based training are becoming the common platform in which schools provide education in online teaching. This…

The question of equivalence between two or more groups is frequently of interest to many applied researchers. Equivalence testing is a statistical method designed to provide evidence that groups are comparable by demonstrating that the mean differences found between groups are small enough that they are considered practically unimportant. Few…

One of the key ideas of evidence-centered assessment design (ECD) is that task features can be deliberately manipulated to change the psychometric properties of items. ECD identifies a number of roles that task-feature variables can play, including determining the focus of evidence, guiding form creation, determining item difficulty and…

Compared to words that are new to a discourse, repeated words are produced with reduced acoustic prominence. Although these effects are often attributed to priming in the production system, the locus of the effect within the production system remains unresolved because, in natural speech, repetition often involves repetition of referents and…

Colleges and universities are being asked by numerous sources to provide assurance of learning assessments of their students and programs. Colleges of business have responded by using a plethora of assessment tools, including the Major Field Test in Business. In this article, the authors show that the use of the Major Field Test in Business for…

Enhancing competency and collaboration has become a salient topic of the professional debate on medical safety issues. The advantages of simulation-based training scenarios for team communication, routines and critical work procedures especially in operation theatres have been vigorously discussed. However, the literature on simulation-based…

Networks and the social capital that they carry enable people to get things done, to prosper in their careers, and to feel supported. To develop an effective network, one needs to know more than how to make connections with strangers at a reception; understanding the consequences of network properties on one's ability to obtain benefits is…

In this article, high school librarian Beth Ebenstein Mulch describes how she used iPads to introduce students at T. C. Williams High School (Alexandria, Virginia) to the school library. Her goal was for the library to come to life in front of new students and for them to learn from peers about all the great resources and services their library…
