Howard Barrows, who was one of the developers of PBL at McMaster back in
the early days, is often bemused at efforts to characterize the method as
coming out of some particular theoretical framework such as constructivism,
Deweyean inquiry (as I tried to do the other day), etc., because he knows
that historically it was not designed with any kind of theoretical
orientation, but rather evolved from some practical concerns about how to
better motivate learning in the first two years of medical school. This
doesn't mean it is atheoretic, of course, but that the original designers
were not operating out of allegence to any particular school of thinking.
However, trying to critically analyze the method, as it is currently
practiced in terms of our current theories about learning, strikes me as an
entirely reasonable thing to do.

I think one of the things that prematurely sends innovations like PBL to
the dust bin of discarded educational "fads" is when the innovation is
presented as a rigid and inalterable set of procedures. I think that the
people who are working with PBL are smart enough to see this danger, but it
is always well to be wary.
