Jonathan (Jon) Bergmann is one of the pioneers of the flipped classroom movement. He has helped schools, universities, organizations, and governments all over the world introduce active and flipped learning into their contexts. A frequent keynote speaker who challenges and inspires audiences with stories and real-life examples from his classroom, Bergmann teaches full-time science and assists with staff development at Houston Christian High School in Houston, Texas.

Both research and personal experience have taught him that students learn best when they are active participants and that they don't care what their teacher knows until they know that their teacher cares. He tries every day to connect with his students.
