Determining the error of measurement is a necessity for researchers engaged in bench chemistry, chemistry education research (CER), and a multitude of other fields. Discussions regarding what constructs measurement error entails and how to best measure them have occurred, but the critiques about traditional measures have yielded few alternatives.…

A new variant of the iterative "data = fit + residual" data-analytical approach described by Mosteller and Tukey is proposed and implemented in the context of item response theory psychometric models. Posterior probabilities from a Bayesian mixture model of a Rasch item response theory model and an unscalable latent class are expressed…

An increasing number of planetariums worldwide are turning digital, using ultra-fast computers, powerful graphic cards, and high-resolution video projectors to create highly realistic astronomical imagery in real time. This modern technology makes it so that the audience can observe astronomical phenomena from a geocentric as well as an…

Cultivating EFL learners' critical thinking ability is an urgent task for English teachers. To integrate the training of language skills and cultivation of critical thinking ability into one language course, the author designed an activity called simplified Modal United Nations conference, which is based on the revised Bloom's Taxonomy that…

In a series of experiments, we tested a recently proposed hypothesis stating that the degree of alignment between the form of a mental representation resulting from learning with a particular visualization format and the specific requirements of a learning task determines learning performance (task-appropriateness). Groups of participants were…

Purpose: This study assessed the feasibility of virtual reality (VR) exposure as an assessment and treatment modality for youth with social anxiety disorder (SAD). Methods: Forty-one adolescents, 20 of which were identified as having SAD, were recruited from a community sample. Youth with and without SAD were exposed to two social virtual…

Purpose: This paper aims to contribute to a general understanding of mental practice by investigating the utility of and participant reaction to a virtual reality maintenance training among underground coal mine first responders. Design/Methodology/Approach: Researchers at the National Institute for Occupational Safety and Health's Office of Mine…

The multilevel latent class model (MLCM) is a multilevel extension of a latent class model (LCM) that is used to analyze nested structure data structure. The nonparametric version of an MLCM assumes a discrete latent variable at a higher-level nesting structure to account for the dependency among observations nested within a higher-level unit. In…

This article reports the analysis of six urban contexts in which a practical tool measuring individual skills concerning household waste recycling was tested. The tool is a structured questionnaire including a simulation task that assesses respondents' abilities to sort household waste adequately in a given context/municipality. Results indicate…

Thermodynamic processes are complex phenomena that can be understood as a set of successive stages. When treating processes, classical thermodynamics (and most particularly, the Gibbsian formulation, predominantly used in chemistry) only pays attention to initial and final states. However, reintroducing the notion of process is absolutely…

"Simulation-based inference" (e.g., bootstrapping and randomization tests) has been advocated recently with the goal of improving student understanding of statistical inference, as well as the statistical investigative process as a whole. Preliminary assessment data have been largely positive. This article describes the analysis of the…

In this study, we aimed to design collaborative virtual learning (CVL) activities by using a five-stage model (FSM) and survey of students' experiences. The study group consisted of 14 voluntary students in the Turkish Teaching Department. In this case study, data were collected through observations, recordings in Second Life (SL) and interviews.…

The contemporary era provides several challenges which extend from the reconstitution of an innovative knowledge domain and curricula to candidate learning platforms that support online course delivery methods. Educators and scholars on these demands have recently started to rethink alternative ways for the assimilation of the experiential…

The subject of this article is the use of augmented reality technology in library and information science education. The aim is to determine the scope and potential uses of augmented reality in the education of information professionals. In order to determine the scope and forms of potential use of AR technology in LIS education a two-step…

Marketing faculties, as well as business schools in general, are placing increasing importance on finding ways to better tie theoretical concepts to real-world situations. In the article that follows, we describe a project wherein students were given an opportunity to apply core consumer behavior concepts to a simulated advertising project with…
