ClassDojo
ClassDojo’s mission is to bring communities together and give them the tools, ideas, and energy to improve education for all kids. Founded in 2011 and based in San Francisco, California, ClassDojo is a school communication platform that millions of teachers, students, and families use every day to build strong relationships and supportive communities. This is done in two ways. One, by sharing what’s being learned in the classroom back home through student portfolios, photos, videos, and messages. And, two, by helping students build social-emotional skills through in-classroom feedback and engaging activities for school and home.
