Westat is contracted for a three-year evaluation. The presentation will present our designs and approaches for addressing the evaluation questions: 1. What does the portfolio of funded projects look like? 2. What percent of development-intensive projects funded in the program employ appropriate methods to evaluate the efficacy and apply them rigorously? What were the methods used to study these projects? What have been the results of these studies? 3. What percent of resources developed by the program are found to be effective and ready for adoption at scale? 4. What are the combined effects of the projects that have been evaluated with rigorous methods? What do these combined effects contribute to the knowledge base about innovative approaches to improving STEM learning and teaching? 5. Do the resources, models, tools, and technologies developed and/or studied in projects lead to significant improvement in student learning? To significant improvement in teacher STEM competency? #Prek-12EducationalEvaluation #2011Conference #GovernmentEvaluation #Research,Technology,andDevelopmentEval
