This project will result in software tools designed to work with commercially available sensing equipment to support early elementary science classrooms in using play to model and simulate science concepts. A curriculum guide will accompany the software tools. The research findings of this study will inform the field about the ways in which young students can engage in authentic scientific modeling, and the ways that technological tools can enhance this process. Furthermore, the research findings will demonstrate how students’ play activities can be leveraged to support academic learning activities in developmentally appropriate ways. Any questions about this study should be directed to Dr. Noel Enyedy at Enyedy@gseis.ucla.edu
