The Zoo and Aquarium Action Research Collaborative (ZAARC) was an NSF-funded project (DRL-1114335) involving four zoos and two aquariums, plus informal science education researchers from TERC (a non-profit educational research and development company in Cambridge, MA), Oregon State University and California State University, Long Beach. The goal of ZAARC was to investigate how action research might be carried out by educators in zoos and aquariums, and how its implementation would impact both the individual practitioners and their institutions.
