Listen now | A teacher’s true impact on the world isn’t seen directly, and isn’t measured. It exists instead abstractly, as a butterfly effect projecting through the lives of students they’ve guided. In Cullen’s and my case, this guidance was in sophomore year U.S. History. Yet, it also extended beyond the classroom, in large part thanks to the unconventional culture of my high school. At the Paideia School, we had discussions (often about race, gender and charged social issues) in a Socratic method, called our teachers by their first names, and frequently grew close with them.
