Why teach Big History? Just ask our teachers...

Students have an instinct to think deeply and feel respected when presented with deep questions. The Big History Project facilitates independent, critical cross-disciplinary thinking, which is what the real world is all about. Our active class discussions and questions reflect this. Wow! — High school teacher, Brooklyn, NY
The curriculum melds multiple disciplines together in a very approachable way, enabling students to create astounding connections and igniting exciting discussions. — High school teacher, Novi, MI
Big History's captivating narrative engages students while challenging them to ask if they have enough proof to believe the story. This translates into better writing, stronger arguments, and a more rigorous, independent approach to their studies. — High school teacher, San Pedro, CA
