Generalized linear mixed models are frequently applied to data with clustered categorical outcomes. The effect of clustering on the response is often difficult to practically assess partly because it is reported on a scale on which comparisons with regression parameters are difficult to make. This article proposes confidence intervals for…

In recent guidelines for fair educational testing it is advised to check the validity of individual test scores through the use of person-fit statistics. For practitioners it is unclear on the basis of the existing literature which statistic to use. An overview of relatively simple existing nonparametric approaches to identify atypical response…

In this article, Michael F. Shaughnessy, Contributing Editor of this journal, interviews David Dockterman, Chief Architect, Learning Sciences, at Scholastic Education, where he provides guidance on turning research into practical programs. Dockterman was one of the founders of Tom Snyder Productions, a leading educational software developer and…

Computers and simulations represent an undeniable aspect of daily scientific life, the use of simulations being comparable to the introduction of the microscope and the telescope, in the development of knowledge. In science education, simulations have been proposed for over three decades as useful tools to improve the conceptual understanding of…

University administrators may invest significant time and resources with the goal of improving their "U.S. News & World Report" ranking, but the real impact of these investments is not well known since, as other universities make similar changes, rankings become a moving target. This research removes the mystique of the "U.S.…

There has been much research and discussion on the principles of standards-based grading, and there is a growing consensus of best practice. Even so, the actual process of implementing standards-based grading at a school or district level can be a significant challenge. There are very practical questions that remain unclear, such as how the grades…

Role-playing is considered a valuable pedagogical strategy in a variety of fields. However, the use of this strategy in teacher education is underdeveloped. In this study we employ script-writing for a play (which we consider imagined role-playing) as a variation on a role-playing method. We invited teachers participating in a Master of Education…

Purpose: Simulation games have long been used as a teaching tool in the classroom environment mainly due to the high level of participation and engagement that students are able to generate from these, making the learning process more enjoyable and capable to replicate real-life scenarios. Feedback given during the simulation helps to motivate…

The effect of recent experience on current behavior has been studied extensively in simple laboratory tasks. We explore the nature of sequential effects in the more naturalistic setting of automobile driving. Driving is a safety-critical task in which delayed response times may have severe consequences. Using a realistic driving simulator, we find…

Computer simulations continue to prove to be a valuable tool in physics education. Based on the needs of an Aviation Physics course, we developed the PHYSics of FLIght Simulator (PhysFliS), which numerically solves Newton's second law for an airplane in flight based on standard aerodynamics relationships. The simulation can be used to pique…

Executive development programs teach various skills deemed important in future leaders and help shape future leadership and its performance. However, they are often excessively focused on competencies required for dealing with internal issues and relationships. They do a much less admirable job preparing future executives for the unique skills…

In this article, we discuss and illustrate two centering and anchoring options available in differential item functioning (DIF) detection studies based on the hierarchical generalized linear and generalized linear mixed modeling frameworks. We compared and contrasted the assumptions of the two options, and examined the properties of their DIF…

This article introduces longitudinal multistage testing (lMST), a special form of multistage testing (MST), as a method for adaptive testing in longitudinal large-scale studies. In lMST designs, test forms of different difficulty levels are used, whereas the values on a pretest determine the routing to these test forms. Since lMST allows for…

This article discusses a number of significant developments in 3D holographic technology, its potential to revolutionize aspects of teaching and learning, and challenges of implementing the technology in educational settings.

Virtual reality is by no means a new technology, yet it is increasingly being used, to different degrees, in education, training, rehabilitation, therapy, and home entertainment. Although the exact reasons for this shift are not the subject of this short opinion piece, it is possible to speculate that decreased costs, and increased performance, of…
