Data Visualizations

About 20 years ago, psychologist Lynn Liben presented an model of the relationships among a learner, an external (i.e. not mental) representation, and those aspects of the real world represented by the representation (the “referent”). Liben notes that the learner can learn either through direct interactions with the real world or through interactions with a representation.

The world is awash with data. This growth of data shows no signs of slowing, and indeed seems to be accelerating. Analyzing data, spotting patterns, and extracting useful information have become gateway skills to full participation in the workforce and civic engagement of the 21^st century. Yet pre-college classrooms are falling short of preparing students for this world. And they’re missing the opportunity to harness the power of big data to transform student learning.

This poster presented the first results from Principal Scientist Kim Kastens’ collaborative grant on “Making Meaning from Geoscience Data: A Challenge at the Intersection between Geosciences and Cognitive Sciences.” ...

This poster was aimed at an interdisciplinary audience who work on all sorts of visualizations across all fields of science and science education. It reports the findings from a study in which we used eye-tracking and video-taped think aloud interviews to study how geoscience novices and experts interpret topographic and bathymetric data visualizations.

The "Fourth Paradigm" of Science, which seeks insight by mining vast archives of existing data rather than by doing experiments to gather new data, is being touted as a new method of doing science.  But Walter Pitman mined data archives in 1966, as did Tanya Atwater in 1970, so is “The Fourth Paradigm” really new?...
