We aim to transform scientific discovery and innovation in education through a scalable data infrastructure that bridges across the many disciplines now contributing to learning science (e.g., cognitive, social, and motivational psychology), discipline-based education research (e.g., Physics, Chemistry, Computer Science), and educational technology (e.g., intelligent tutoring, dialogue systems, MOOCs). The data infrastructure building blocks (DIBBs) we are developing and integrating are available online at learnsphere.org.
