Fed up and fired up, algebra teacher Josh Katz this spring took to the stage for a 17-minute denouncement of what he called the "toxic culture of education" in Florida's public schools.
Since then, nearly 30,000 people on YouTube have viewed the University High School teacher's impassioned attack on high-stakes testing, Common Core academic standards, private education companies and the false "narrative" that "public schools are teeming with horrible teachers."
His talk, delivered at a conference in Ohio, earned a mention from a Washington Post columnist, praise from education historian and activist Diane Ravitch and emails from colleagues saying "thanks for speaking up."
