The CMSC conference series was initiated in 2013. The aim is to explore new ways of communicating the rich algorithmics and mathematics underlying computer science. The conference aims also to engage research mathematical scientists in outreach and communication. Bringing together researchers, educators and communicators committed to bringing exploration and discovery into classrooms and among the educated public, the conference hopes to explore new ways of thinking initiated by Computer Science Unplugged and other similar efforts. We invite researchers, teachers, students and everybody interested in innovative teaching ways.
