I've been thinking a lot recently about how scientists and students make meaning from data, spurred in part by the Earth Cube education end-users workshop. Among other things, I've been trying to understand what kinds of deeply foundational understandings might be constructed by young children through unstructured observation using the human senses, and then later re-purposed as they begin to work with data.
Here is one candidate: Future data users need to understand that:
I have a long-standing interest in the use of data in education, so I've been reading with interest several articles and a book concerned with the so-called "Fourth Paradigm" of science, in which insights are wrested from vast troves of existing data. The Fourth Paradigm is envisioned as a new method of pushing forward the frontiers of knowledge, enabled by new technologies for gathering, manipulating, analyzing and displaying data. The term seems to have originated with Jim Gray, a Technical Fellow and visionary at Microsoft's eScience group, who was lost at sea in 2007. The first three paradigms, in this view, would be empirical observation and experimentation, analytical or theoretical approaches, and computational science or simulation. Earth and Environmental Sciences are well represented in the book, with essays on data-rich ecological science, ocean science, and space science.
I am finding these readings very stimulating and worthwhile. But I question whether this way of making meaning from the complexity of nature is really so new. More
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
Recently my "Teaching & Learning Concepts In Earth Sciences" students and I renovated one of my old data-using lab activities, from the days when I used to teach "Planet Earth" to non-science majors. The old version of the activity led students step-by-step through a series of manipulations of an on-line global data base, using a professional data visualization tool. The old directions provided a lot of scaffolding for how to make data displays of ocean salinity in and around the Mediterranean Sea, but little support for how to extract insights about earth processes from those displays. The new version assumes that students are already pretty adept at getting computer apps to do what they want, and refocuses the scaffolding on how to think like a geoscientist, how to think about the meaning of the data.
