AP* CHEMISTRY
Dale Jensen
history

Dale Jensen has taught Chemistry and Physics for North Medford High School for the last 33 years. Coming out of University of Oregon with a BS in Chemistry and a BS in Biology, Dale soon started teaching the Talented and Gifted students. For the past seventeen years, Dale has enjoyed teaching First Year Chemistry, AP* Chemistry, and Physics. For the past twelve years Dale has been an AP* Chemistry Reader/Table Leader and has worked as a consultant for the College Board* conducting weekend and week-long workshops. Dale has been asked to come back as a Table Leader for the 2010 exam. In 2007, Dale was appointed to the SAT Test Development Committee for the Chemistry specific test.

Outside interests include Tennis and computers. As a tennis coach at North Medford, Dale received his USPTA card, was Coach-of-the-Year three times, and was twice named the Western Regional Coach-of-the-Year for Women's Tennis. Dale has also published software as a fellow with the Journal of Chemical Education and is currently writing coaching software that is still under development.

session outline
Brief Course Description: During the week that we are together, we will look at the entire AP* Chemistry curriculum, the 2010 Test (fresh from the reading), and the labs that make for a good Advanced Placement Program. I like to think of this week as a time to share. I know that you will come away with a better understanding of AP* Chemistry, because I always learn from each presentation that I conduct.
