You wouldn't tell a heart surgeon to also do pediatrics--so why would we tell content area educators they must "do" literacy? Math, history, English and science teachers are passionate about their specialties, and that's why authors Releah Lent and Marsha Voight designed a framework that keeps teachers' subjects at the center of daily classroom life while also helping them pool strengths with colleagues. Based on years of successful implementation, this powerful PL cycle "drops in" seamlessly to any school setting, so teachers schoolwide take on innovative practices of reading, writing, thinking, and doing within their areas of expertise.
