  1. Research Experience for Teachers (NSF 0502327): Instructional Modules for Integrating Biomedical & Nanoscale Sciences in School Classrooms Carolyn Vallas (PI)Director of the U.Va. Center for Diversity in EngineeringJuliet TrailRET Program Coordinator, Center for Diversity in Engineering

  2. RET Program Rationale • NSF’s RET programs encourage active participation of K-12 teachers in science, technology, engineering, and mathematics (STEM) research, to enable them to teach STEM concepts to their students and to encourage students to pursue careers in engineering and computer science • Supports national efforts to develop a skilled 21st-century American workforce, specifically in the STEM fields • Change the Equation 2010 address by President Obama: “Leadership tomorrow depends on how we educate our students today–especially in science, technology, engineering and math.....[Our success] depends on us restoring an insistence on excellence in our classrooms and from our children.” • National Science Board Report 2009 report, Essential Components of an Effective STEM Education System, include • Need for high-quality teachers • Need to provide teachers with world-class resources and assistance • Enable early student exposure to STEM concepts in pre-kindergarten and elementary school

  3. RET Program Description • U.Va. Site Focus: “Instructional kits and modules for integrating biomedical and nanoscale sciences in school classrooms.” • Summer 2010 Program: 15 Teachers, 5 Weeks • 3 elementary, 5 middle, 7 high school; 14 in-state, 1 out-of-state • Conducted independent research investigations in Biomedical, Civil/Environmental, Electrical/Computer, Materials Science, Mechanical, & Systems Engineering as well as Physics • Annual Teacher’s Workshop – INNOVATION: Teaching Nanotechnology within Virginia SOLs

  4. RET Summer Program Description • Host Laboratory: Faculty Mentor, Graduate Students • Support: Weekly Stipend, Housing, Meal Stipend • Learn about Research Projects of Host Lab • Conduct Independent Investigations & Experiments • Weekly Program Meetings, Special Presentations • Societal & Ethical Dimensions of Nanotechnology Course • Weekend Excursions (Tour of Monticello, James River Tubing)

  5. RET Summer Program Outcomes • Teachers create novel teaching kit based on summer research • Correlate kit & lesson plan(s) to all related SOLs • Present kit and research poster at RET Final Colloquium • Submit short Research Paper outlining RET research & kit • RET2 – return for second summer • Broader Impacts: Present to home districts, state & national meetings • Articles In Press: American Society for Engineering Education & Virginia Journal of Science Education (VJSE)

  6. RET Summer Program Assessment • Assessment for 2010 program via 2 surveys • Program Survey on final day of program (100% response) • Classroom Extension Survey to be distributed May 2011 • Gather feedback on RET teaching kits • Track presentations or articles beyond individual classrooms • Investigate ways to assess student learning outcomes • Was the target population reached? • Target: Recruit teachers from schools serving high proportions of those under-represented in STEM, including African American, Hispanic, Native American, and Free/Reduced Lunch populations • 53% of 2010 participants are in schools with high minority populations (African American, Hispanic, &/or N. American) • 40% of school districts served by RET teachers exceed the VA free/reduced lunch average of 38% (at 49-59%)

  7. RET Summer Program Assessment • Summer Program Survey Responses Positive* • “This experience was exactly what I wanted. It will translate directly into my teaching.” • “I loved the RET experience. I gained many opportunities that would otherwise be unavailable to me in my home county. I will share my experience with my colleagues, friends, and family. I was prepared for the amount of work that was requested of me in the program. Thank you for such a great experience!”

  8. Innovative Module for Elementary School:Carrie Lewis, Robotic Twiddlefish Module • Research Project: Modeling Skeletal Architecture of Batoid Fins and their Motions • Faculty Mentor: Dr. Sylvia Blemker, M3 Lab • Department of Mechanical and Aerospace Engineering • Dearing Elementary, Lynchburg • 98% African American, 59% Free/Reduced Lunch • Teaching Module: • Students pursue testable questions about force, motion and the relationships of form to function. • They will collect data to prove or disprove their ideas and present their findings using charts, graphs, and workable models.
