This research study is a collaborative research initiative with Oregon State University. Women from five different long-standing informal science programs for girls will participate in this study to explore the role that informal science learning (e.g. museums, Girl Scouting) plays in supporting girls’ long-term interest, engagement, and participation in science communities, hobbies, and careers. This important study will develop a model for understanding the impact of informal science learning with broad application across informal programs and will disseminate these findings through informal science and gender-based research and practice fields.
