Schoolwires® Greenleaf program supports 21st century learning, leveraging students’ natural desire to engage and learn from their peers. As they collaborate on projects and learn together through safe social communication, students in the U.S. and China gain a deeper understanding of global issues and how to interact effectively with people from a different country and culture. More than a virtual learning program, Greenleaf is an international cultural exchange opportunity designed to promote digital and global citizenship.
