Part of AEA 2013 panel presentation. (Also see Eval13 Session 20: Reframing: The Fifth Value of Evaluators' Communities of Practice for rest of presentations in panel.) Using the evaluation of a scale-up project (a five-year effort to expand an underwater robotics program for youth nationally) as a case study, this presentation will describe issues that can emerge after reframing a project as a Complex Adaptive System. Three unanticipated issues emerged as critical to this project’s ability to scale up and sustain itself: (1) the ability to adapt to the local context (e.g., the project team redesigned the classroom curriculum to meet the needs of informal educational settings); (2) the need to pay attention to issues beyond the project’s boundaries (e.g., the discontinuation of equipment critical to the curriculum); (3) the capacity to sustain the project when grant funding ends (e.g., having expertise to market commercial versions of the training and curriculum). Reframing the evaluation to incorporate systems thinking into data collection helped to identify these issues and bring them to the attention of the project team. #SystemsinEvaluation #OrganizationalLearningandEvalCapacityBuilding #STEMEducationandTraining #2013Conference
