This poster will present results from an NSF funded research project examining evaluation capacity building efforts (ECB) in a complex adaptive system (CAS), the Nanoscale Informal Science Education Network (NISE Net). The NISE Net is a national community of researchers and informal science educators dedicated to fostering public awareness, engagement, and understanding of nanoscale science, engineering, and technology. The research is taking place within the NISE Net system using surveys, interviews, artifact analysis and observations. The research team is a unique mix of insiders and outsiders to NISE Net, which allows the incorporation of a variety of perspectives on the interpretation of the data collected. The poster will present literature-based frameworks for examining both ECB and CAS, document NISE Net as a CAS, describe the aspects of the ECB occurring within the system, and provide evidence illustrating how the CAS and ECB interact.#SystemsinEvaluation #2014Conference #ArtsCultureandAudiences #OrganizationalLearningandEvalCapacityBuilding
