My name is Dr. Zach Groshell and welcome to my podcast!

In this episode, I welcome Adam Robbins to Progressively Incorrect for a conversation about one of the biggest challenges in education: improving teaching. Together, we explore why teacher development is often so difficult and why schools need more than good intentions to make meaningful progress.

This episode looks at several of the key levers schools use to develop teachers, including lesson observation, feedback, coaching, professional development, and accountability. Rather than offering simple answers, the conversation digs into the tensions, decisions, and tradeoffs involved in helping teachers get better over time.

🚨 Registration is open! 🚨

Love what you heard? Inwood Academy is hosting my The Explicit Teaching Institute—a five-day deep dive into the science of learning and the highest-leverage moves in explicit instruction – in New York City this summer.

We’ll spend our mornings unpacking the research, our middays studying expert teaching on video (courtesy of Steplab!), and our afternoons rehearsing the moves that make instruction clear, efficient, and reliable—so you leave with a practical toolkit you can use on day one. 

🗽 NYC | July 27–31, 2026
