The Making Learning Visible Project draws attention to the power of the group as a learning environment. In the first phase of MLV (1997-1999), Project Zero, a research group at the Harvard Graduate School of Education, in collaboration with the Municipal Infant-toddler Centers and Preschools of Reggio Emilia, Italy, explored documentation as a central component of group learning and produced a book: Making learning visible: children as individual and group learners. In phase II (1999-2002) Project Zero researchers collaborated with prekindergarden to grade 8 teachers from the Cambridge Children's Center and the Cambridgeport School in Cambridge, MA and the Exra H.
