This reasoning process is found throughout geosciences. For example, Marie Tharp's discovery of the rift valley of the Mid-Atlantic Ridge came about as she slogged through thousands of kilometers of echo sounder profiles and extracted the common schema of a rift-shaped feature reminiscent of the East African Rift Valley.

I was leading an Earth Science teacher professional development workshop recently, and the subject turned to models: physical models, computer models, data models, mathematical models, graphical models, etc. Afterwards, one of the teachers said to me "Well, it seems like EVERYTHING we use in teaching Earth Science is a model."
And I said, "Well, it's not THAT extreme. Rocks aren't models....." More
All in all, I'm a fan of the New York State Earth Science Regents course and of the accompanying Earth Science Regents exam. New York state enrolls more students in high school level Earth Science than any other state, and confronting the common exam has helped to build a community of practice among New York State Earth Science teachers that is the envy of Earth Science teachers in other states. I especially like the emphasis on building and assessing representational competence–the ability to understand and make inferences from diagrams, maps, profiles, block diagrams, graphs and other visual representations.
However, I have to say that the most recent Earth Science Regents exam (August 20ll) had two really terrible diagrams, so bad that I think they are more likely to sow confusion than illuminate earth processes. More
The most interesting thing I learned over Thanksgiving arrived during a pre-dinner walk along a rural Massachusetts road heavily impacted by the Halloween storm. Many tree limbs were shattered, fallen to the ground or dangling from their parent trees. My cousin's daughter's friend Mike pointed out that the broken limbs still had their leaves, browned and stiff but still connected, while the healthy trees had lost all their leaves. The rest of us looked more carefully, and sure enough, his observation was correct, tree after tree. More
In contrast, many of my colleagues concerned with the quality of science education in other disciplines moan and groan about how hard it is to get college faculty to pay attention to research on learning or to change their teaching practice. So how–by what mechanism–does the Cutting Edge approach work? Here's an idea. More
