Hello all...

I am looking for three items of information that I am hoping some of  
you may be able to help me with.  The first of these is your favorite  
quote regarding the importance of fieldwork in constructing geoscience  
knowledge.  One that I've found thus far comes from Rob Butler's  
"Teaching Geoscience through Fieldwork"

It is quite possible to acquire a considerable knowledge of Geology by  
the mere intelligent perusal of text-books. Without having engaged in  
practical work, one may even learn to read a geological map, and come  
to understand in a general way the structure of the region it  
portrays. Knowledge obtained in this fashion, however, is necessarily  
superficial, and can never supply the place of personal observation or  
study in the field.
James Geikie (1912)

While this one does a pretty good job explaining the importance of  
fieldwork to geology education, it misses the mark in terms of the  
importance of fieldwork in constructing the body of knowledge.  The  
other two items I'm looking for are references regarding the nature  
and frequency of fieldwork in K-16 classrooms and in teacher education  
in geoscience.  Most of what I'm finding here seems to be for the UK,  
which is interesting, but not very useful when talking to folks here  
in the states.

Thanks for whatever info you might be able to send in my direction
