The theoretical reason for the presence of differential item functioning (DIF) is that data are multidimensional and two groups of examinees differ in their underlying ability distribution for the secondary dimension(s). Therefore, the purpose of this study was to determine how much the secondary ability distributions must differ before DIF is…

This article presents a unit of study in which students examine skeletons and draw conclusions from the evidence they find in a simulated mass grave. The activity involves the foundation of forensic anthropology--interpreting the structure of skeletal remains to determine sex, age, height, and possible cause of death. Working through a series of…

Attempting to educate practitioners of computer security can be difficult if for no other reason than the breadth of knowledge required today. The security profession includes widely diverse subfields including cryptography, network architectures, programming, programming languages, design, coding practices, software testing, pattern recognition,…

In their journey to becoming doctors, students engage with a range of teachers and trainers. Among these are simulated patients (SPs), who, through role-playing, assist students to develop their communication and physical examination skills, in contexts of formative and summative assessments. This paper explores the teaching and learning…

Introduction: With a definition that is evolving, a serious component of the contract cheating issue involves individuals paying a third-party to complete assessment items for them and then submitting this work as if it were their own. The issue of contract cheating poses a significant problem for tertiary institutions. The research literature…

Policymakers are increasingly interested in the extent to which experimental results generalize from a sample to a population of inference. When the sample is not randomly selected, propensity score methods are used to reweight the sample. Subclassification by propensity score is commonly used in which the population is partitioned into strata…

This design case includes the challenges, considerations, and decisions associated with the design, development, and delivery of a master's level educational technology course on teaching and learning with games and simulations. A master's level course, Digital Games and Simulations in the Classroom, faced redesign in order to add a gamification…

This essay introduces and analyzes a one-class role-play simulation during which students engage in stakeholder negotiations on how to respond to a large flow of refugees between two fictional African countries. Participants acquire an in-depth knowledge of arguments regarding granting and restricting refugees' freedom of movement and civil and…

Interprofessional education (IPE) aims to introduce students to the importance of team-based decision making. This article presents evaluation data from an IPE poverty simulation event. The goals of the project were to increase students' understanding of the barriers faced by families in poverty, and to increase students' confidence when working…

In response to the rising need for Spanish-English interpreters in the United States, there has been an increase in translation and interpreting and Spanish for the health professions courses in Spanish language programs (Martínez 2015). However, before Spanish students are exposed to a clinic or hospital context, they may have limited experience…

This study explores the effect of rapidly transitioning an in-person pre-licensure nursing specialty course to remote instruction during the COVID-19 pandemic. The redesign included the following learning technologies: live and recorded whiteboard lectures with Socratic-style questioning, electronic audience response systems, remote simulations,…

Teaching digital literacies as social practices is challenging for many English as an Additional Language (EAL) practitioners. There is not much research that offers effective approaches and specific examples. Drawing on the '3D' model (Green [2002]. "A Literacy Project of Our Own." "English in Australia" 134: 25-32), this…

Similar content has tremendous utility in classroom and online learning environments. For example, similar content can be used to combat cheating, track students' learning over time, and model students' latent knowledge. These different use cases for similar content all rely on different notions of similarity, which make it difficult to determine…

Developing students' practical skills in strategic staffing and selection within the classroom can be challenging. This article describes a staffing system simulation designed to engage students and develop applied skills in strategic recruiting, assessment, and evaluation of job applicants. Instructors looking for a multifaceted team project…

Numerical simulations are playing an increasingly important role in modern science. In this work it is suggested to use a numerical study of the famous perihelion motion of the planet Mercury (one of the prime observables supporting Einsteins general relativity) as a test case to teach numerical simulations to high school students. The paper…
