"What DOES poison oak look like?"


Posted: Jul 16 2012 by Kim Kastens
Topics: Perception/Observation, Field-Based Learning

The front cover of the current issue of The Economist documents the power of modern science, celebrating the finding of the Higgs boson as "a giant leap for science." But the back cover of the same issue documents the abject failure of natural history education in America. More

Too Fast to Measure

Cover of Synthesis volume I'm thrilled to report that the book that grew out of the Synthesis project, the parent project of this blog, is now out: Earth & Mind II: A Synthesis of Research on Thinking and Learning in the Geosciences, Geological Society of America Special Publication 486, edited by Cathy Manduca and myself. It's available from the Geological Society of America bookstore

However, having shared my thrill at holding the book in my hands, I have to admit that there are some ideas in the book that I have already outgrown during the months that the book has been in production. More

A more nuanced view of Concept-driven versus Data-driven visualizations


Posted: Mar 12 2012 by Kim Kastens
Topics: Interpretation/Inference, Spatial Thinking, Perception/Observation
In several previous posts, I explored how Clark & Weibe's (2000) idea of data-driven versus concept-driven visualizations plays out in geosciences and how this distinction could be important as we help students learn to learn from visualizations. This semester, in my course on "Teaching & Learning Concepts in Earth Sciences," students found and documented visualizations that afford insights via spatial thinking about a topic they are working on for a semester long project. Applying the idea of data-driven versus concept-driven visualizations to this image collection surfaced several additional nuances to the categorization schema. More

Turning Nature Into Categories

Topics: Metacognition, Perception/Observation, Interpretation/Inference

Two years ago in this space, I wrote about "Turning Nature into Numbers," humanity's accomplishment of developing instruments and methodologies that can turn the fleeting qualitative impressions that we have of our surroundings into quantitative values–numbers–which can be readily stored, shared, transmitted and compared.

Numbers are great, but it seems to me that for developing an opinion or making a decision, humans often want categories rather than numbers. More

Questions we don't think to ask

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
