Several schools, including Sugata Mitra’s School in the Cloud, the Evangelical School Berlin Centre (ESBC) in Germany, and Ricardo Semler’s Lumiar in Brazil are radically reinventing education for the twenty-first century. Gone are traditional grades, lectures, and subjects, replaced with an integrated approach that honors active participation and curiosity. Everyone—students, parents, and faculty—is expected to participate in the creation of the curriculum. These institutions are cracking the code on education.
