This book of readings is part of EL Education’s 25th anniversary celebration. Scraps of paper tucked into notebooks, dog-eared pages from our favorite authors, and long memories have finally been brought together to create this collection. It reaches back into our heritage with Outward Bound and the Harvard Graduate School of Education to elevate the values that have guided us since our inception. And it draws on some of the seminal documents that have guided our work for many years—such as the Design Principles and the Dimensions of Student Achievement—that will carry us into the future. This book of readings draws on the accumulated collections of many EL Education staff, teachers, and school leaders and is curated with educators and students in mind.
