I spent my first year teaching on an emergency credential--a B.S. degree in Math and a pulse. I spent my next two years on an intern credential while I taught during the day and went to ed school (an alternative credential program) at nights and on weekends.
Very little of what we learned in ed school was applicable to the real world of teaching, especially for secondary teachers. This post by Joanne (see blogroll) hits the nail on the head.
