The Broken Copier
TLDR
Honest, affirming accounts of classroom life from a teacher who shows the lesson rather than just the conclusion, with a podcast that puts teachers first.
Started by two teachers on opposite sides of the country, The Broken Copier is a Substack and podcast built on a simple idea: teachers talking about teaching. Marcus Luther, now in his fifteenth year in high school classrooms, walks through real lessons week by week — the analogies that land, the October slump, the AI conversations happening in front of him — while the podcast centres teacher voice over expert pronouncement.
