"If you’re reading this, you’re likely well versed in what it takes to become a teacher. Either you became one yourself, oversee teachers, or work alongside them … you already know teachers are miracle workers.But how did they get that way? How did teachers learn their craft? If only there was some sort of quick overview of the past, present, and future of teacher education. From the past (in 1834, Pennsylvania became the first state to require future teachers to pass a test of reading, writing, and arithmetic) to the future (the projected job growth of elementary and middle school teachers is 17%), there’s a lot to see."
