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…

An Educational Testing Service (ETS) procedure was evaluated, which is based on item response theory and estimates true scores on tests not taken. The reading, vocabulary, and mathematics tests of high school seniors from the National Longitudinal Study (NLS) of 1972 and the High School and Beyond (HSB) seniors of 1980 and 1982 were found to share…

Describes the hardware and software, typical application, future use, and initial results of an evaluation of a program which enables future teachers to practice their teaching skills on microcomputer-simulated students. These "students" are programed with such characteristics as enthusiasm and prior knowledge and are able to interact.…

Discusses the need for educational change and ways to achieve it. Topics include problems with testing, the importance of learning by doing, the lack of Internet's educational value, and the possibilities of using computer software to create real-life simulations for students to learn by doing and to design new curricula. (LRW)

Suggests that the most effective way to motivate student enthusiasm and interest in the social studies classroom is through the use of educational simulations. Discusses the advantages and disadvantages of simulations, and presents three of the most effective commercial simulations available today. (DB)

School to Career is part of a national initiative to help students make connections between the content, skills, and concepts they are learning in the classroom and careers in the real world. School-to-career practices add relevance to the elementary school curriculum and promote engagement in learning. A key feature of many school-to-career…

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…
