Dave,
The College Board is a huge bureaucracy and operates as such. I am
not associated with them in any way but I do follow closely what they
do in CS. My intention was not to defend their policies or
procedures, but simply to state some facts of life. My wife (and
co-author) is a College Board "consultant" for New England, which
means she conducts workshops and summer institutes for teachers --
she's taught hundreds of teachers. She has been grading AP exams for
13 years, and was on the College Board's "ad hoc committee for
teacher professional development in Java." The fact that such a
committee was set up speaks for itself.
High school CS teachers -- and I've met many of them, personally and
via email -- are not professional programmers. They don't spend
their days studying new languages or programming tools. Some have
experience working in the industry; most have no CS degree and are
self-trained. Many also teach math. Some take a week-long summer
course and that's their whole preparation from scratch for teaching
an AP CS class in September. It is not easy for an average teacher
to quickly learn a new programming language or methodology. The
following quote from today's ap-compsci listserv gives a little history:
The first APCS exam was in 1984; Pascal was the language used. In
1999 the language was switched to C++; in 2004, the language was
switched to Java.
My impression is that AP doesn't contemplate language switches
lightly; as you can see, Pascal was the language of use for fifteen
years. The process to switch over from Pascal to C++ took a full
five years, when you look at the development of the exam,
instructional materials and training for teachers, case study, and so
on. In one of those weird little quirks of history, Java blossomed
onto the scene in the middle of that transition ... my sense from
what I've heard is that APCS would've moved straight to Java if it
could have, but the move to C++ was underway too far to attempt to
redirect that change. Gratefully, the transition from C++ to Java
wasn't nearly as difficult, with both languages being object-oriented
and sharing common syntax.
