"The Digiteen™ Project is a global hands-on project for middle and early high school students, (typically Grade 6-9, 11-15 year old) which was founded by Julie Lindsay (now in Beijing, China) and Vicki Davis (Camilla, GA USA) in 2008. This project studies digital citizenship with students researching current topics, writing a collaborative report on a wiki, and performing and documenting offline action educational projects to promote effective digital citizenship at their local schools. The purpose of the project is to educate on and promote effective Digital Citizenship and responsible online choices as well as immersing students into an educational community for learning and collaborating."
