I am keeping my weekly Extra Credit column alive on this blog with occasional answers to reader questions, the format of that column I did for many years in the Extras before they died. This teacher, Michael Feinberg (no relation to the co-founder of the KIPP schools with the same name), sent me a copy of an intriguing letter about physics he sent to the Montgomery County school superintendent, and agreed to let me get an answer and use it here.
Dear Dr. Weast:
I am a retired MCPS teacher; I taught Physics at both Kennedy H.S. and Whitman H.S. until the time that I retired in 2005. After retirement I have, on occasion, tutored Physics students.
When the 9th grade Physics curriculum was introduced I opposed it on the grounds that Physics should be taught at a higher mathematical level. While tutoring students in both grades 9 and 11/12 I see that this is true; students in 11th grade learn rigorous Physics with mathematical applications while students in 9th grade usually do descriptive worksheets. I believe that it unfair that students in 9 th grade receive the same honors credit for what is promoted as the same curriculum but is not the same.
