I seem to be on a data visualization kick this week. Yesterday I highlighted the coolness of Many Eyes for text analysis. On the same day one of my favorite tweeps, @ToughLoveforX, shared Revisit, a project by Moritz Stefaner who is a freelance “information visualizer.” As soon as I clicked on Revisit, I was smitten from both my visual data geek tendencies and as an educator.
Stefaner’s Revisit allows you to “see” the connections happening across various Twitter streams and hashtags. As a professional development provider and educator, Twitter is one of those tools that can take a while for someone to get the gist of (See earlier post on DABEL model for Social Media PD). One of the common complaints I hear from my students and colleagues is that Twitter is so hard to follow. Often I will introduce TweetDeck or Twitterfall (etc), as helpful tools to follow the progression of conversations. Some of my students and workshop attendees will then “get it” a bit more, but there is always a group of visual learners that are really trying to conceptualize the relationships of the tweets; particularly retweets and how people are truly connected. This is where Revisit is particularly powerful.
I did a sample infographic of the #edchat hashtag from 8/7/2010 at 11:30am EST. Click here to interact with this example (give it about 3 seconds to load). Also note, to the right of the Revisit screen, you can also type in your own search terms.
Stefaner comments this as a great way to create a Twitter wall for conferences, offices, and I would propose classrooms as well. Imagine visualizing your backchannel conversations in this way and seeing the connections come to life, as well as visualizing the major influencers and branches in the dialogue.
Individuals and organizations can download the source code for their own stand alone implementations. Stefaner does note that due to current API limitations the only the tweets from the last 8 days are captured and retweets via the Twitter website are not captured. However, as an immediate infographic and quick analysis tool, it’s very effective. I invite you all to Revisit, and see your Twitter experiences in a new way.
I am attending the Personalized Learning Symposium (#perLearn on Twitter) in Boston, MA this week. Today’s first group breakout session asked us to describe the qualities and characteristics that make a personalized learning environment. At the completion of the conversation, one thing remained clear -we have a lot of ideas but no clear consensus. The lexicon for personalized learning is still developing.
I asked Molly McCloskey, Manager of Whole Child Programs at ASCD, and convener in the Bartlett Room breakout session, to email me the collected table notes to see if I could create visualizations from our words. My goal is straightforward: can we see immediate patterns and connections from our combined words? I usually use Wordle for some instant feedback. The result was okay, but didn’t make this diffuse topic any clearer. So I turned to IBM’s Many Eyes site which allows multiple visualization types (including Wordle). Here are the results:
The next three are a series of branching diagrams showing the connection of one word, to many thoughts & phrases. As you view these diagrams click on some of the words and see what happens.
Branching Diagrams: Students
Branching Diagrams: Learning
Branching Diagram: Teachers
The Classic Tag Cloud
Many Eyes is also capable of creating data driven visuals using specific word counts to create a variety of relationship diagrams. I pulled the master word count list out of Worlde to generate an example of one of these options. For this to truly work, I need to go in a clean up all the “is, a, the, of , ands”…well you get the point.
Bubble Plot Example:
For me the clear winner was the branching diagrams for this exercise. What is really great is that you can type different words into the textbox to see if they can be mapped. Many Eyes is a free service and works simply by cutting and pasting your text into a basic text box. From there you can create interesting visuals for your data analysis. Do I dare say its a tad bit personalized? Enjoy!
This post talks about how wordle can be used to rethinking and visualize the main ideas of reading. Examples from “A Nation at Risk” and “A Blueprint for Ed Reform” are used.
The amount of blogging time I have is pretty much 0-2% these days. After work, I devote my idle hours to doctoral studies and family (and sadly in that order some days).
One thing about graduate work is the volume of print reading has not changed since I was in my Master’s program in 98-99. Darn. Synthesizing lots and lots of text quickly is a challenge for anyone. As a teacher educator, I am always demonstrating the use of certain tools to help organize and visualize text and data for k12 students. So wouldn’t it be a novel idea to actually use some myself? I imagine anyone reading this might be saying –well golly yes– you just realized that?
I’ve been using Wordle a bit more to validate (or invalidate) perceptions of readings, especially articles that I have read before and already have formed strong value statements about. In my summer Historical Perspectives on Education course, we were assigned the classic A Nation At Risk report from 1983. I was feeling a bit more sour than usual about ed reform. Chatter in the online discussion of my course turned to a bit of griping that not much has changed in our reform rhetoric since 1983. After completing a Worlde for #edchat this morning, I began to wonder if perhaps Wordle could help me see and perceive our impressions of a Nation at Risk differently, especially in comparison to a current policy document? If our class believed nothing had changed, we should see more similarities than differences between the two. In my mini-experiment I selected the recommendations section from A Nation At Risk, and compared it to the recommendations of the recent Blue Print for Reform for the reauthorization of the ESEA. Here is what happened:
Wordle Recommendations Section from a Nation At Risk (1983)
Worlde Recommendations from a Blue Print for Reform (2009)
I haven’t had chance to do a comprehensive analysis of each Worlde. Here are just some quick reactions:
- That students were the most commonly used word in both reports. While we may not agree with the rhetoric in one or both of the documents, students are clearly at the center.
- Support is a huge theme in our current ed reform rhetoric and it was not even on the map in At Risk.
- A Nation At Risk is focused on k-12, with emphasis on teachers and students and preparing teachers.
- Blueprint expands our thinking and focus; administrators and districts are mentioned frequently. Mentions of parents and community also appear.
- Teachers are integral to both reports. But, the focus on teacher preparation through universities in the At-Risk report is not the core focus of the Blue Print recommendations.
- Hmmm where did learning go in the Blue Print?
- In the Blue Print, schooling is focused on preparing us for college, not just successful graduation from high school.
- At Risk focused on the “Basics” that students need to master. Standards appear to be our new basics.
- Content based knowledge mentioned throughout the at risk. New reform rhetoric focused more on accountability and performance.
- Heavy focus on nationalism in At-risk and national status.
I am glad I did this little exercise. We are inundated with so much information online, I know I am scanning my content more and forming assumptions and opinions quickly. While I didn’t walk away thinking “Wow, we’ve really changed! Reform now is soooo much better,” it helped me clarify my thinking and even rethink how I approach discussing this with my classmates. Even though I had read At Risk many times, there is something intangibly powerful about visualizing the main themes of the text in a new way. And, because I am not getting any more free time to read, I did as I tell my teachers to do with their students: I stepped back, utilized a tool designed to assist and enhance my understanding.
For any readers out there; do you ever Wordle, or use another tool, to help you with our own personal work and learning? This little exercise got me wondering about how often as educators we use the same tools we give our students for our own personal learning and reflection?
