One of the greatest opportunities of this technology, one that is yet untapped, is the window that it opens into understanding human learning. The data that one can measure is unprecedented in both the level of detail and in its scale. Thus, we can apply data analytics in entirely new ways to understand what works and what doesn’t, ranging from general educational strategies to specific design choices for a given course. This transformation from a hypothesis-driven to a data-driven mode has revolutionized other disciplines, such as biology, and may now allow us to systematically improve the quality of education. This paradigm, which combines meaningful work that can be graded at scale with peer-teaching among students, allows us to offer some of our best educational content to students around the world, at a negligible marginal cost of pennies per student. It therefore makes feasible the notion of universal education, with the potential of some remarkable consequence.
