We design learning experiences to turn boring classrooms into labs for discovery. Our goal is to teach students the important skills of STEAM - science, technology, engineering, arts, and mathematics - through interdisciplinary challenges. For example, students might build a musical instrument that incorporates elements of science, technology, engineering, arts, and mathematics. We assess students not through exams or grades but by the projects they make. We teach skills like thinking, making, playing, and improving to train students to invent the future.
