Changes in household-level actions in the U.S. have the potential to reduce rates of greenhouse gas (GHG) emissions and climate change by reducing consumption of food, energy and water (FEW). This project will identify potential interventions for reducing household FEW consumption, test options in participating households in two communities, and collect data to develop new environmental impact models. It will also identify household consumption behavior and cost-effective interventions to reduce FEW resource use. Research insights can be applied to increase the well-being of individuals at the household level, improve FEW resource security, reduce climate-related risks, and increase economic competitiveness of the U.S. The project will recruit, train, and graduate more than 20 students and early-career scientists from underrepresented groups. Students will be eligible to participate in exchanges to conduct interdisciplinary research with collaborators in the Netherlands, a highly industrialized nation that uses 20% less energy and water per person than the U.S.
This study uses an interdisciplinary approach to investigate methods for reducing household FEW consumption and associated direct and indirect environmental impacts, including GHG emissions and water resources depletion. The approach includes: 1) interactive role-playing activities and qualitative interviews with homeowners; 2) a survey of households to examine existing attitudes and behaviors related to FEW consumption, as well as possible approaches and barriers to reduce consumption; and 3) experimental research in residential households in two case-study communities, selected to be representative of U.S. suburban households and appropriate for comparative experiments. These studies will iteratively examine approaches for reducing household FEW consumption, test possible intervention strategies, and provide data for developing systems models to quantify impacts of household FEW resource flows and emissions. A FEW consumption-based life cycle assessment (LCA) model will be developed to provide accurate information for household decision making and design of intervention strategies. The LCA model will include the first known farm-to-fork representation of household food consumption impacts, spatially explicit inventories of food waste and water withdrawals, and a model of multi-level price responsiveness in the electricity sector. By translating FEW consumption impacts, results will identify "hot spots" and cost-effective household interventions for reducing ecological footprints. Applying a set of climate and technology scenarios in the LCA model will provide additional insights on potential benefits of technology adoption for informing policymaking. The environmental impact models, household consumption tracking tool, and role-playing software developed in this research will be general purpose and publicly available at the end of the project to inform future education, research and outreach activities.

This is a proposal for a 3 year, $1,297,456 project to be conducted as collaboration among 5 higher education institutions and one school system across the country, with St. Joseph's University in Philadelphia, PA serving as the lead institution (other collaborators are from Colorado School of Mines, Ithaca College, Santa Clara University, Duke University, and Virginia Beach School System). The primary goal is to attract and retain students in computer science, especially women and underrepresented minorities (including two EPSCoR states). To this end, the project will use Alice, a software program that utilizes 3-D visualization methods, as a medium to create a high-level of interest in computer graphics, animation, and storytelling among high school students, hence to build understanding of object-based programming. Such an IT focus on media and animation is aligned with national computer science standards. The project will build a network of college and high school faculty, who will offer workshops and provide continuing support during the academic year. In each site, pairs of teachers from each participating school (total = 90) will learn with university faculty via a 3-week summer program in which an introduction to using Alice for teaching will be followed by teacher development of materials for students that will then be used to teach high school students. An experimental start at one site will be followed by implementation at four additional sites and culminated with revised implementation at the sixth site (1-4-1 design).
This project will study two emerging and innovative technologies: interactive, dynamic simulations and touch-based tablet devices. The use of touch-based tablet technology (e.g., iPads) in the classroom is rapidly increasing, though little research has been done to understand effective implementation for learning science. Interactive simulations are now in use across K-16 levels of education, though what impact tablet devices have on the effective implementation of science simulations is not yet known. This project will explore this new frontier in education, over a range of contexts, providing new insight into effective interactive simulation design, classroom facilitation techniques, and the effects of tablet-based simulation use on underrepresented populations in STEM courses. Together, Dr. Emily Moore (PhET, UCB), a leader in interactive simulation design and classroom use, and Dr. Roy Tasker of the University of Western Sydney (UWS), a leader in chemistry education research, science visualizations, and teaching with technology, will research on the new technology frontier in science education - laying the groundwork for future investigations of foundational questions in technology use for learning science. This work has great potential to transform the future of science learning, making it both more engaging and more effective for diverse populations. The research findings will immediately impact 1) the design of new and existing PhET simulations - reaching millions of students and teachers using PhET simulations worldwide - and 2) the development of best practices guidelines for teachers using tablet technology to increase student learning, engagement, and participation in STEM disciplines.
The PhET Interactive Simulations group at the University of Colorado is expanding their expertise of physics simulations to the development of eight-to-ten simulations designed to enhance students' content learning in general chemistry courses. The simulations are being created to provide highly engaging learning environments which connect real life phenomena to the underlying science, provide dynamic interactivity and feedback, and scaffold inquiry by what is displayed and controlled. In a second strand of the project, a group of experienced faculty participants are developing and testing lecture materials, classroom activities, and homework, all coordinated with well-established, research-based teaching methods like clicker questions, peer instruction, and/or tutorial-style activities, to leverage learning gains in conjunction with the simulations. The third strand of the project focuses on research on classroom implementation, including measures of student learning and engagement, and research on simulation design. This strand is establishing how specific characteristics of chemistry sim design influence engagement and learning, how various models of instructional integration of the sims affect classroom environments as well as learning and engagement, and how sim design and classroom context factors impact faculty use of sims. To ensure success the project is basing sim design on educational research, utilizing high-level software professionals (to ensure technically sophisticated software, graphics, and interfaces) working hand-in-hand with chemistry education researchers, and is using the established PhET team to cycle through coding, testing, and refinement towards a goal of an effective and user friendly sim. The collection of simulations, classroom materials, and faculty support resources form a suite of free, web-based resources that anyone can use to improve teaching and learning in chemistry. The simulations are promoting deep conceptual understanding and increasing positive attitudes about science and technology which in turn is leading to improved education for students in introductory chemistry courses both in the United States and around the world.
The Physics and Chemistry Education Technology (PhET) Project is developing an extensive suite of online, highly-interactive simulations, with supporting materials and activities for improving both the teaching and learning of physics and chemistry. There are currently over 70 simulations and over 250 associated activities available for use from the PhET website (http://phet.colorado.edu). These web-based resources are impacting large number of students. Per year, there are currently over 4 million PhET simulations run online and thousands of full website downloads for offline use of the simulations. The goal is that this widespread use of PhET's research-based tools and resources will improve the education of students in physics and chemistry at colleges and high schools throughout the U.S. and around the world. This PhET project combines a unique set of features. First, the simulation designs and goals are based on educational research. Second, using a team of professional programmers, disciplinary experts, and education research specialists enables the development of simulations involving technically-sophisticated software, graphics, and interfaces that are highly effective. Third, the simulations embody the predictive visual models of expert scientists, allowing many interesting advanced concepts to become widely accessible and revealing their relevance to the real world. And finally, the project is actively involved in research to better understand how the design and use of simulations impacts their effectiveness - e.g. investigating questions such as "How can these new technologies promote student understanding of complex scientific phenomena?" and "What factors inhibit or enhance their use and effectiveness?".
