Data Visualization

Roughly everything we do online is content of some sort. Each click can be captured. Each thought expressed in digital format serves as a future connection point. The trails we leave may not have much value today, but when someone decides to analyze trails left through a data mining tool, suddenly our data becomes alive (again). Educators have done a very poor job of visualizing and analyzing the data trails left by students. Several years ago, Alec Couros, Clarence Fisher, and I discussed setting up an educational analytics model to help teachers/learners/administrators understand ways to make use of data for learner purposes. Not much came of that. But the concept of effective use of the data produced by learners continues to grow in importance. I’d like, for example, to have a Google Data Explorer tool for education. Instead of confined to educator control (as LMS reports currently are), this tool should be available to both learners and educators. Awareness of trends and hidden patterns can be for great meta-learning.

    Agreed! One of my colleagues at HASTAC just tweeted this great resource from SXSW in Austin, and it seemed appropriate to add it here: http://www.visual-literacy.org/periodic_table/periodic_table.html

    It’s great for helping educators think about visualization, but it would be a great tool to share with students too.
