Take it away, Ken (in the third person):
Kenneth Bernstein began fulltime teaching in 1995 after a career in data processing and a varied background including service in the Marines, selling cars, selling incense in Greenwich Village (it was the '60s), and other odd and interesting occupations, all of which he thinks broadens his perspective as a teacher. With degrees in Music, Religion, and Education, naturally he teaches Social Studies (in which he has National Board Certification). He blogs on a variety of topics at a variety of places (including at their initiative at the New York Times) where usually he writes as "teacherken" although occasionally under his own name. ABD in Educational Administration and Policy Studies, he promises never to inflict his proposed dissertation upon the unsuspecting world. But beware, he is spreading across the internet.
