Educators nationwide are forging their way in a landscape shaped by pandemic-induced disruptions. Training resources designed to spark new thinking often feel outdated – especially if they were published before 2020. To address this need, the Center on Reinventing Public Education at Arizona State University and CPRL produced teaching case studies that showcase the successes and challenges of high schools improving or redesigning the student experience. Our three new case studies of authentic high school dilemmas include a narrative of each school and accompanying questions designed to generate grounded, in-depth discussions of key issues related to innovation and equity in high school education. Each teaching case is intended for groups of leaders and design teams learning about or engaged in high school reinvention. (February 2023)
