A networked improvement community can be a tremendous resource for people who share a common interest and desire to learn from each other, and, thanks to technology, this can occur even when participants are separated by a large distance. This article discusses Virginia Advanced Study Strategies' Rural Math Innovation Network, a four-year project funded by a U.S. Department of Education Investing in Innovation (i3) grant. The Rural Math Innovation Network is a virtual networked improvement community of middle and high school math teachers. Participants collaborate to share and learn best practices for helping students develop growth mindsets and self-efficacy in mathematics, specifically pre-algebra and algebra 1. Experience with participating teachers and leaders as well as an evaluation study have supported the hypothesis that connections across geographic boundaries are valuable for teachers and, ultimately, for students. This article discusses how Virginia Advanced Study Strategies developed the Rural Math Innovation Network to address major challenges to professional learning in rural districts, where teachers are often isolated both professionally and geographically (Beesley & Clark, 2015). Further, it describes how Virginia Advanced Study Strategies built their network in 18 school divisions in southwest and southside Virginia and what made it successful for participating teachers and administrators in this area.
