One step further in the journey to 0 classroom, 0 teachers and 135 kids and 4 teachers working as treat servants instead

A teacher-in-training darted among students, tallying how many needed his help with a history unit on Islam. A veteran math teacher hovered near a cluster of desks, coaching some 50 freshmen on a geometry assignment. A science teacher checked students’ homework, while an English teacher spoke into a microphone at the front of the classroom, giving instruction, to keep students on track.

One hundred thirty-five students, four teachers, one giant classroom: This is what ninth grade looks like at Westwood High School, in Mesa, Arizona’s largest school system. There, an innovative teaching model has taken hold, and is spreading to other schools in the district and beyond.

Five years ago, faced with high teacher turnover and declining student enrollment, Westwood’s leaders decided to try something different. Working with professors at Arizona State University’s teachers college, they piloted a classroom model known as team teaching. It allows teachers to dissolve the walls that separate their classes across physical or grade divides.
