As Julie knows, I spend most of my time with some of the leaders in
the use of physical and numerical models in the surface processes
realm, though I was trained in one of the most field intensive
undergrad programs around. What I have concluded, from many years
listening to this debate is that very few modelers dismiss field work,
especially in one's early career, for exactly the reasons Jeff Dodick
points out.

It sounds like Frank is dealing with courses for non-majors. In the
absence of good data, perhaps it would help to point to two federally
funded efforts, that demonstrate a firm belief in the community in
the value of exposure to both methods of understanding the Earth.

The first is the Earth Science Literacy Principles, funded by NSF, and
developed as a community driven consensus based document to gather the
Big Ideas and Supporting Concepts necessary for all Americans to be
literate in Earth Science. The first Big Idea is about how Earth
scientists do their work and supporting concept 1.3 lists the methods
we use, with both field work and modeling included equally.

The other is the GLOBE program. This has been around since 1995, has
been invested in by numerous federal agencies, and actually has been
adopted worldwide. It is for K-12 teachers and students, but it is
based on the concept that if children gather data according to the
same protocols used by Earth scientists, they can then manipulate
their own data to begin to understand the modeling process. In this
case, the data itself is nothing revolutionary--mostly gathered in the
school yard--but it is the pedagogy of experiencing the data
collection that is emphasized.
