Outreach

• 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
• I am one of 6 PIs on a 5-year NSF grant worth $8,996,840, to work with 12 school districts to address the low mathematics achievement in this region through a coordinated effort that focuses not only on the schools, but also on universities' teacher preparation, and on community and parental support.
