This report explores the premise that there's nothing more powerful than great teachers skillfully using great instructional materials to motivate and engage students in their learning. Three real-world examples illustrate how schools and school systems are working to support teachers to skillfully use high-quality, standards-aligned curricula, by providing teachers with the time and expertise to use those curricula well, with a focus on team-based, collaborative learning. The report also provides lessons learned across these sites and action steps to get schools and districts started on the journey.
