The Girls RISEnet project convened an international community to explore the role of science centers in issues of gender equity in STEM learning. This effort resulted in two major products, including this international literature review that synthesizes what is known about how science centers and museums contribute to girls' engagement with STEM, summarizes what is useful for practice, and identifies gaps in the research. In addition, an international survey identified common global themes and issues and began to outline opportunities for science centers and museums to advance gender equity.
