For all of you who are opposed to the notion of 'physics first', take a
look at what your colleagues overseas are doing. How many of you have
been impressed by the content knowledge possessed by foreign students?
The reason is simple, they don't encounter physics for the first time in
their final year of secondary school. Rather, they've had bits and
pieces all along. Part of my student teaching was at a sixth form
centre in the UK. If I compare the depth of understanding those
students had to that of my current US high school, well, there's no
comparison. The UK students (weren't all British, one class had
representatives from five continents) had experienced physics throughout
their education. As a result, when we studied electronics, we looked at
the behavior of RLC circuits, where as in the US, I'm lucky if we can
distinguish series from parallel.
Certainly there are some topics in physics that don't require
knowledge of advanced math concepts and therefore could be dealt with
prior to the real 'physics' course. Or at least, there are ways of
approaching some concepts that won't doom the concrete-reasoners to
certain failure. This would allow the 'physics' teachers to spend more
time on real physics instead of devoting a large chunk of the year to
things like kinematics(algebra). I too would blow this off as some
idealized situation if I hadn't seen it in action.
Cheers,
Matt
