Multilingual learners (MLs) often struggle with science conceptual learning partly due to the abstractness of the concepts and the complexity of scientific texts. This study presents a case of a Virtual Reality (VR) enhanced science learning unit to support middle-school students' science conceptual learning. Using a transformative mixed methods…

The COVID-19 pandemic has generated an unprecedented wave of challenges for students, faculty, and staff. In March 2020, a thousand community colleges in the United States shifted to online instruction, which affected around 10 million students. Community colleges are used to responding to their communities during times of crisis. But individual…

To address the problem of limited opportunities for practicing second language speaking in interaction, especially delicate interactions requiring pragmatic competence, we describe computer simulations designed for the oral practice of extended pragmatic routines and report on the affordances of such simulations for learning pragmatically…

Understanding and characterizing treatment effect variation in randomized experiments has become essential for going beyond the "black box" of the average treatment effect. Nonetheless, traditional statistical approaches often ignore or assume away such variation. In the context of randomized experiments, this paper proposes a framework…

Nurturing experiences in preparation for prospective early childhood educators' work with families during their training are critical for establishing empowering relationships. This article details a qualitative case study of 77 prospective early childhood educators engaged with the Parent, Family and Community Engagement Simulation. An electronic…

This article describes the process by which the authors created a Virtual Learning Community for cultural and linguistic exchange between college students of Portuguese in the United States and undergraduate and graduate students of English in Brazil. In addition to describing the way the so-called tandem model for telecollaboration was adapted to…

While the rise in childhood obesity is clear, the policy ramifications are not. School nutrition programs such as the School Breakfast Program (SBP) have come under much scrutiny. However, the lack of experimental evidence, combined with non-random selection into these programs, makes identification of the causal effects of such programs…

In emergency management, scientific models are widely used for running hazard simulations and estimating losses often in support of planning and mitigation efforts. This work expands utility of the scientific model into the response phase of emergency management. The focus is on the common operating picture as it gives context to emergency…

Augmented Reality (AR) simulations superimpose a virtual overlay of data and interactions onto a real-world context. The simulation engine at the heart of this technology is built to afford elements of game play that support explorations and learning in students' natural context--their own community and surroundings. In one of the more recent…

Higher education institutions are under significant pressure to provide affordable, sustainable approaches that will prepare their students with the skills they will need after graduation to achieve success in the 21st Century workplace. Digital Media Simulations are among the new technologies that have emerged with the promise to help…

From 2004-2007, the University of Memphis carried out the NSF-funded Tri-P-LETS (Three P Learning Environment for Teachers and Students) project to improve local high-school computer science curricula. The project reached a total of 58 classrooms in eleven high schools emphasizing problem solving skills, programming concepts as opposed to syntax,…

The bricks-and-mortar infrastructure of community colleges has not nearly kept pace with increases in student enrollments. Not only are colleges bursting at the proverbial seams, but, according to the American Graduation Initiative, many two-year institutions "face large needs due to deferred maintenance or lack the modern facilities and…

This report describes work using nationally representative 2005 data from the School Nutrition Dietary Assessment-III (SNDA-III) study to develop a simulation model to predict the potential implications of changes in policies or practices related to school meals and school food environments. The model focuses on three domains of outcomes: (1) the…

Involving two or more academic subjects, interdisciplinary studies aim to blend together broad perspectives, knowledge, skills, and epistemology in an educational setting. By focusing on topics or questions too broad for a single discipline to cover, these studies strive to draw connections between seemingly different fields. Cases on…

During periods of high unemployment, many workers exhaust their unemployment insurance (UI) benefits before regaining employment. To help alleviate this problem, Congress created the extended benefits (EB) program, expanding the number of weeks of benefits available to UI recipients in high unemployment states. The EB program operates by…
