This project provides logistical and substantive support to the IMD, TPC, and DR-K12 grantees funded by the National Science Foundation (NSF). Working collaboratively with the principal investigators and NSF program officers over a five-year period, EDC has coordinated four of five annual Principal Investigators conferences and is establishing a knowledge-transfer network that includes developing print and Web-based resources to ensure ongoing, high-quality dialogue and sharing among grantees.
