Statisticians have developed propensity score methods to improve generalizations from studies that do not employ random sampling. However, these methods rely on assumptions whose plausibility may be questionable. We introduce and discuss bounding, an approach that is based on alternative assumptions that may be more plausible. The bounding…

The current article provides an overview of a Teacher Professional Development (TPD) program that has been designed, pilot tested, and implemented to investigate the impact of augmented reality (AR) on: (a) Teachers' level of technology (AR) acceptance, adoption of inquiry-based instructional approaches, and confidence towards teaching…

Facilities are the foundation for safe and effective STEM teaching and learning, and the manner in which they are initially designed can either enhance or impede the quality of a program. This new focus on facilities in the U.S, and particularly in Texas, is needed to engage students in relevant and meaningful learning experiences that are aligned…

"Hall of Heroes," a digital game, was used to compare social and emotional skills of 63 adolescent female students matched for age across Malaysia, South Africa, and the United States. Participants were assessed on six social and emotional competencies during game play, namely impulse control, cooperation, communication, social…

Although earthquakes themselves do not kill people, they highlight the critical importance of physical infrastructure resilience, safety measures and preparedness for natural disasters. Earthquakes are one of several environmental crises that can be categorized as a natural hazard/disaster. This study uses the qualitative method of research. The…

This paper gives an overview of nine different Virtual School Garden Exchange (VSGE) projects. In VSGEs, learners from primary or secondary schools with school gardens exchange virtually on their garden experiences and related topics, using digital media like emails, photos, films, or videoconferences. In this manner, the global perspective of…

The Change Laboratory methodology offers the potential to support expansive learning in preservice bilingual teacher education. This qualitative case study examines how ten preservice Chinese and Korean bilingual teachers, who participated in a Change Laboratory intervention, engaged one of the major Change Laboratory instruments, the four-field…

Background: The host of costly individual and societal consequences of alcohol, tobacco, and other drugs (ATOD) use underscores the importance of ATOD prevention education. "It's Up 2U" is an evidence-informed, game-based, e-learning ATOD prevention program developed by Children's Health Education Center (CHEC) targeting middle school…

The number of online courses, programs, and schools are growing exponentially in K-12 education. Given the unique nature of online courses and the distinct skills necessary to create a quality online course, it is essential that effective professional development be provided for teachers designing online courses. Online courses need to be of the…

The goal of this research study has been to develop, implement, and evaluate a school reform design experiment at a continuation high school with low-income, low-performing underrepresented minority students. The complexity sciences served as a theoretical framework for this design experiment. Treating an innovative college preparatory program as…

High school students have had some difficulties in understanding chemistry due to traditional ways of teaching this specific science. It is important to improve teaching methods that increase student motivation, not only to enhance their capacity for understanding, but also to generate a greater level of interest in the study of chemistry for…

This paper presents results from fiscal impact simulations of three national-level policies designed to prevent unintended pregnancy: A media campaign encouraging condom use, a pregnancy prevention program for at-risk youth, and an expansion in Medicaid family planning services. These simulations were performed using FamilyScape, a recently…

Of the eight practices of science identified in "A Framework for K-12 Science Education" (NRC 2012), helping students develop and use models has been identified by many as an anchor (Schwarz and Passmore 2012; Windschitl 2012). In instruction, disciplinary core ideas, crosscutting concepts, and scientific practices can be meaningfully…

The purpose of this paper is to illustrate the authors' interaction-engagement approach in facilitating online courses, which focused on a guided inquiry approach to build understanding of core science concepts using hands-on experimental science investigations. The graduate-level courses were taught during 2005 through 2010, entirely online. The…

The V-SPACE project equipped English teachers with iPads as tools to create and maintain virtual spaces for their students. Teachers learned effective ways to integrate technology with English content while strengthening technological knowledge and pedagogical skills. In a summer institute, 29 high school teachers were trained, using their iPads,…
