Purpose: The purpose of this paper is to present a case study of City & Guilds' development of simulation-based assessments for its ICT user qualification. These simulations are authentic scenario-based replicas of word processing and spreadsheet software, which present a series of tasks that the test-taker completes as if they were using…

Chemists have used computational science methodologies for a number of decades and their utility continues to be unabated. For this reason we developed an advanced lab in computational chemistry in which students gain understanding of general strengths and weaknesses of computation-based chemistry by working through a specific research problem.…

User-created virtual worlds, such as Second Life, are a hot topic in higher education. Thousands of educators are currently exploring and using Second Life, and hundreds of colleges and universities have purchased and developed their own private islands in Second Life, including the University of Kansas Medical Center (KUMC). Because it is so easy…

Background: Computer-assisted tools are rarely adopted for dental education in China. In China, 3D digital technology, such as Virtual Reality Systems, are often rejected in the dental field due to prohibitive pricing. There is also a reluctance to move away from traditional patterns of dental education. Objective: The current study is one of a…

The purpose of this study was to document how teachers and students describe and comprehend the ways in which participating in an augmented reality (AR) simulation aids or hinders teaching and learning. Like the multi-user virtual environment (MUVE) interface that underlies Internet games, AR is a good medium for immersive collaborative…

Google Earth (GE) is proving to be a valuable tool in the science classroom for understanding the environment and making responsible environmental decisions (Bodzin 2008). GE provides learners with a dynamic mapping experience using a simple interface with a limited range of functions. This interface makes geospatial analysis accessible and…

Scale linking is the process of developing the connection between scales of two or more sets of parameter estimates obtained from separate test calibrations. It is the prerequisite for many applications of IRT, such as test equating and differential item functioning analysis. Unidimensional scale linking methods have been studied and applied…

At the level of clinical speech/language evaluation, the repetition type of conduction aphasia is characterized by repetition difficulties concomitant with reduced short-term memory capacities, in the presence of fluent spontaneous speech as well as unimpaired naming and reading abilities. It is still unsettled which dysfunctions of the…

This paper arose from a larger study designed to explore what leaders in the field of sociology think are the most important goals and principles for students to understand after taking a college-level introductory course and how they teach those principles. A population of scholarly leaders in sociology was defined by various forms of peer…

IMS Learning Design (IMS-LD) is a specification to create units of learning (UoLs), which express a certain pedagogical model or strategy (e.g., adaptive learning with games). However, the authoring process of a UoL remains difficult because of the lack of high-level authoring tools for IMS-LD, even more so when the focus is on specific topics,…

Interactive computer simulations with complex representations and sophisticated graphics are a relatively new addition to the classroom, and research in this area is limited. We have conducted over 275 individual student interviews during which the students described what they were thinking as they interacted with simulations. These interviews…

This article shows that measurement invariance (defined in terms of an invariant measurement model in different groups) is generally inconsistent with selection invariance (defined in terms of equal sensitivity and specificity across groups). In particular, when a unidimensional measurement instrument is used and group differences are present in…

Focusing on reading methods and practices in rural Indian Mexico at the turn of the twentieth century, this article explains why schooling had little impact in terms of literacy in Spanish yet played a successful political and ceremonial role resulting in what I call a ritual literacy. At the time, the emerging educational system did not consider…

Mathematical software packages such as Polymath, MATLAB, and Mathcad are currently widely used for engineering problem solving. Applications of several of these packages to typical chemical engineering problems have been demonstrated by Cutlip, et al. The main characteristic of these packages is that they provide a "problem-solving environment…

A-DNA and B-DNA are two secondary molecular conformations (among other allomorphs) that double-stranded DNA drawn into a fiber can assume, depending on the relative water content and other chemical parameters of the fiber. They were the first two forms to be observed by X-ray fiber diffraction in the early 1950s, respectively by Wilkins and…
