We've all had great teachers who opened our minds — and maybe even changed our lives. But how can we make every teacher a star teacher? Elizabeth Green's New York Times best-selling book 'Building a Better Teacher: How Teaching Works (and How to Teach It to Everyone)' presents teaching as a complex skill — one that requires infrastructure for support and training. She gives examples of the methods America's best educators are using in the classroom, as well as how Japan's education system has adopted policies that have changed teachers across the country. Green discusses her book with Stanford University's renowned mathematics education professor Jo Boaler. Boaler is co-founder of YouCubed, and online resource for educators and families.
