1. “The Informal Science Education (ISE) program at the National Science Foundation (NSF) invests in projects designed to increase interest in, engagement with, and understanding of science, technology, engineering, and mathematics (STEM) by individuals of all ages and backgrounds through self-directed learning experiences. In addition to these public audience impacts, projects must demonstrate how they seek to advance the knowledge and practice of informal science education.” David A. Ucko in Alan J. Friedman, ed.Framework for Evaluating Impacts of Informal Science Education Projects: Report from a National Science Foundation Workshop(2008): 9–13.
