The present study aimed at investigating the effect of using some proposed kinesthetic activities on developing EFL oral language performance for the primary governmental language students. Participants of the study were 33 students in primary six from Hassan Abu Bakr governmental language school in the academic year 2016-2017. The researcher's…

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…

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…

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…

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…

Applications of multilevel models to continuous outcomes nearly always assume constant residual variance and constant random effects variances and covariances. However, modeling heterogeneity of variance can prove a useful indicator of model misspecification, and in some educational and behavioral studies, it may even be of direct substantive…

Although a strategy for business innovation is to turn a concept into something that's desirable, viable, commercially successful and that which adds value to people's lives but in the fast changing world, we are seeing weakening of relationship between product, user and the environment, thereby causing sustainability issues. A concrete futuristic…

This simulation study compared the utility of various discrepancy measures within a posterior predictive model checking (PPMC) framework for detecting different types of data-model misfit in multidimensional Bayesian network (BN) models. The investigated conditions were motivated by an applied research program utilizing an operational complex…

While simulations and role-play have been staples in the civic classroom, little is known about how they work as best practices. This study explores the ways simulations and role-play may influence students' civic identities. Drawing from sociocultural theories, the article seeks to understand how students' practice-linked identities may be shaped…

Often in sociology, researchers are confronted with nonnormal variables whose joint distribution they wish to explore. Yet, assumptions of common measures of dependence can fail or estimating such dependence is computationally intensive. This article presents the copula method for modeling the joint distribution of two random variables, including…

Approaching the new media literacies as social practices through the lens of Participatory Culture Framework, the present study adapted new media literacies to online social networks and examined the social media literacy practices of international graduate students (IGSs). The data was collected through an online survey of 90 IGSs,…
