This proposal was submitted in response to the STEM + Computing Partnerships (STEM+C) program solicitation NSF 15-537. The STEM+C program seeks to advance new approaches to, and evidence-based understanding of, the integration of computing in K-12 science, technology, engineering and mathematics (STEM) teaching and learning. Twin Cities Public Television in partnership with the National Girls Collaborative Project (NGCP) and the University of Minnesota Learning Technologies Media Lab, will implement A National Connected Learning Model to Integrate Computing in STEM Learning with Middle School Girls. Even though technology is pervasive in modern life, women continue to be underrepresented in computer science (CS) study and professions. Decades of research suggest the issues that contribute to CS pipeline deficits are complex, and they begin early. Although girls and boys do not display a significant difference in their abilities in math and science, research suggests that the cause for the gap in CS is social and environmental.
