In this presentation, Girlstart proposes an informational talk on innovative, informal STEM education models particularly for girls and nontraditional learners. Founded in Austin in 1997, Girlstart is one of the few community-based informal education nonprofits in the nation specifically dedicated to empowering and equipping K–12 girls in STEM. Since its inception, Girlstart has served more than 22,000 girls and 5,500 teachers and families through school- and community-based programs—held at the Girlstart Science & Technology Center in Austin and other venues throughout Central Texas—including afterschool clubs, summer camps, science career conferences and expos, large-scale science events for families, teacher professional development, online teaching and learning resources, and virtual learning communities. Girlstart's presentation will also include discussion concerning expansion of its programs outside of Central Texas ('Girlstart To Go') as well as opportunities for peer collaboration, partnerships, and resource sharing.
