  • NASA Project Director for the last 2.5 years, 2009-2013 ($499,000)

  • In 2012-2013 have helped run a program for 26 bright high school children who spend a week at Auburn University, interacting with faculty from math, chemistry, biology, physics and geology.
  • I have just completed an NSF grant to take 3 graduate students to Central Australia to design and run math two camps each year for 5th to 9th grade students in the middle of Australia, some of the participants being aboriginal children. The camps go from Friday to Sunday. I have done this for 4 years (2009-2012), the last 3 times with graduate students. The graduate students are a mix of PhD students in Math or Math Ed, the Math Ed students also being current teachers. I also run a workshop for teachers, letting my students do some of the teaching, and take the students to an aboriginal school where we have taught a class and interacted all day with the teachers and children. On returning to Auburn, we initiated a problem solving day for middle school teams where explanations of their answers was more important than speed. Graduate students are now running the upcoming second such event.
  • Since 2001, I have conducted 5 summer workshops on ``Critical Thinking and Problem Solving", a Discrete Math Leadership Institute for K-8th Grade Teachers'' to work with teachers in high need areas of Alabama. Each workshop lasts from 5 to 8 days, and involves 3 follow-up meetings in the ensuing school year. Also involved in this project are master teachers, some from Alabama who have been through the program, others coming from places such as Arizona, Ohio, Rhode Island and Texas. Funding for the project has come from the Eisenhower Foundation, the NSF, the Educational Foundation of America, Auburn University, and the involved school districts. The program was developed at Rutgers University by Joe Rosenstein. For more information on this effort, see Discrete Math Institutes
  • From 2003 to 2009 I was a PI on an NSF MSP to work with 15 local school districts spread over a 2500 square mile area, Tuskegee University, and both Math Ed and Math faculty, to develop an aligned math curriculum that meets both the new AL Math Content and the NCTM process and content standards. This is funded by a $9,361,840 grant from the NSF (I was one of 5 PIs) and a $100,000 internal grant from Auburn University Outreach and the Colleges of Education and Sciences and Mathematics.
