The thread about what we are teaching next year got me thinking. How many of you plan your own courses or is the curriculum written by your school or your state? At my school, we do curriculum maps of each course. We have 3 main science teachers--one for physics (me), one for chemistry, and one for biology. We each write all the curriculum--honors and regular for our course and if another teacher is needed to teach then they follow the curriculum that we wrote. I am in the process right now of re-writing our physical science course to update it.
