The Macroscope

May 24, 2015 by

As a public school teacher, I frequently feel overwhelmed by the sheer amount of information I receive. I get data about student performance, about equity measures, about student’s lives and about parent’s aspirations. Yet at some point during my graduate coursework I started to rethink how I approached exactly what value I was getting from […]

A “New Data Epistemology”

May 17, 2015 by

Does visualizing data change the way you think about that data?  I believe it does.  But so does what data we are collecting in the first place.  This will be a lengthy post.  But stick with it.  In the end, I hope to propose what I term the “new data epistemology.”  It is something I […]

My conclusions: Awesome book. Buy it here: Now You See It: Simple Visualization Techniques for Quantitative Analysis. With the advent of computerized visuals in the late 1960’s, statistician John Tukey pointed out that exploring data would be one of the greatest strengths of interactive computers. In Now You See It: Simple Visualization Techniques for Quantitative […]

Data visualization and educational efficiency

January 12, 2013 by

Can data visualization be used in the classroom? I recently stumbled on some research suggesting that presenting information visually may have significant benefits over text-based materials. The BBC reports that interpreting visual data requires fewer cognitive resources than reading texts. The results showed that when tasks were presented visually rather than using traditional text-based software […]

Using statistics to lie, and why democracy needs statistical literacy

August 3, 2012 by

I have often argued that we should encourage more statistical literacy in school and society in general.  This is not just because I am a statistics nerd.  Statistics is a language just like English; you can use it to describe the world, to clarify and the generalize.  You can also use it to lie or […]

I am a busy person these days.  I have been teaching at a San Antonio community college and will be moving next semester to teaching High School Algebra I.  Also, among other things, I have been researching education data for a national nonprofit. During this project, I needed to simplify some visualizations.  Not dumb down, […]

A new infographic – please comment

November 2, 2011 by

This is going to be a short post. I recently made an infographic for a client.  It actually started out as a poster for an academic conference, which was why I went with a simple, white/blue/black design, but they wanted a web-compatible format as well.  I have almost no experience with this kind of work, […]

I recently wrote a brief post suggesting that data visualization may, in fact, have a place in education. I think a recent find from BYU may be able to elucidate this point further. David Wiley, a Professor at Brigham Young, suggests that teachers may want to visualize test grades in an easily understandable form using a new […]

The Potential for Data Visualization in Education

October 22, 2011 by

I have been spending my free time during the last couple of days putting together a paper for an upcoming e-learning conference in Austin, TX (Society for Information Technology & Teacher Education).  The theme, which at least I find potentially very interesting, is using data visualization in education, both for teaching and assessment. A colleague […]
