Marie Quisumbing (Manager of Early Childhood Initiatives at COSI) and I are attending the bi-annual NSF Advancing Informal STEM Learning (AISL) PI Meeting, February 29 through March 2, in Bethesda, MD. We will present a poster about the Expanding Repertoires project. The meeting is hosted by Center for Advancement of Informal Science Education (CAISE). Posters and other materials from the meeting are available on informalscience.org, including our poster and notes from the Open Space Session on STEM and Early Childhood Education (which I nominated and facilitated)
