Blended learning that combines digital instruction with live, accountable teachers holds unique promise to improve student outcomes dramatically. Schools will not realize this promise at large scale with technology improvements alone, though, or with technology and today's typical teaching roles. This brief explains how schools can use blended learning to encourage improvements in digital instruction, transform teaching into a highly paid, opportunity-rich career that extends the reach of excellent teachers to all students and teaching peers, and improve student learning at large scale. This is called a "better blend": combining high-quality digital learning and excellent teaching. Schools can immediately pursue a better blend at small scale. To achieve excellent learning at scale, state policymakers must change state policy to enable and incentivize a better blend in large numbers of schools. These policies must address five categories: funding, people, accountability for learning, technology and student data, and timing and scalability.
