I have been a high school science teacher in the Dubuque Community School District since 1999. I received my B.S. from the University of Wisconsin-Platteville and my M.A. from the University of Northern Iowa. I began flipping my Anatomy and Physiology curriculum in 2012 and it has totally changed my teaching…what is essential? how can it be assessed? how can I offer choice? how can I individualize my classroom?
