About 200,000 new teachers enter classrooms every year, many not prepared for the jobs that await them. As teaching and learning has evolved over the years, especially with the advent of technology in the classroom, teacher training has remained relatively unchanged. In traditional teacher training programs on college campuses, candidates pay tuition and spend most of their time in courses studying educational theory. What they don't spend time studying, is the actual task of managing a classroom full of children. There are some things that cannot be learned inside the classroom, but rather need to be experienced, hopefully under the guidance of a mentor. Take a look at the NYTimes investigation into learning inside the classroom. The idea is that teachers, like doctors in medical residencies, need to practice repeatedly with experienced supervisors before they can be responsible for classes on their own.
