Visualizing Data and Text – A Comparison Learning Strategy that Works

Comparing is the most powerful instructional strategy you can use in the classroom. But it's the person who does the comparing that's learning. Therefore, we must ask students to develop the comparison, not just learn and repeat the model that we present to them. (Remember, asking a student to fill out a Venn diagram that you created, is just a graphic form of information filing). After they have designed their comparison, students should also be asked to share what they learned.  A major component of 21st century literacy is finding meaningful ways to share information with others.

Many Eyes is a great new website that gives teachers and students a chance to easily use sophisticated graphic tools to analyze data and create interactive displays. Those who register at the site can use 16 visualization types to present data. My favorite visualization is the "Wordle," which enables you to see how frequently words appear in uploaded text, or see the relationship between a column of words and a column of numbers. You can tweak your word "clouds" with different fonts, layouts, and color schemes. Why not have your students use Wordle to analyze a selection of non-fiction text to uncover the main ideas and key vocabulary of the piece? Or they could compare text from different sources. Want your students to more fully understand your course content? Let them use Many Eyes to visualize and discover patterns as a catalyst for discussion and collective insights about information, text, and data. As they say at Many Eyes, "Finding the right way view your data is as much an art as a science. The visualizations provided on Many Eyes range from the ordinary to the experimental."

Here's a few examples of the same data in three different Wordle visualizations that analyze the frequency of words in 30 school district mission / vision statements.

The original data and was uploaded to Many Eyes by PPreuss and used to create the visualization above.  I modified the existing online data set mission / vision statement words with the Wordle tools to represent the same data in different layouts and styles. In this second version (below)  I limited the analysis to the top 100 words.

Here's a third representation of the same source data that analyzes 2-word clusters and displays their frequency in alphabetical layout. Below is  a screen shot of the Tag Cloud, but in its original form at Many Eyes, when I click on any of the word clusters,  a pop-up shows the context of how the cluster is used in different sentences from the source mission / vision statements.

Wow! Looks like we educators have a lot on our plates. Personally I think we might want to admit our mission / vision may simply be  "Trying Hard Not To Become Obsolete."

Your Students Will Never Be Late for Class Again

Like all teachers, I struggled for years with tardy students – “But Mr. Pappas, I had to stop at my locker!” Then I took a lesson from fellow teacher – Tom O’Brien, the art teacher in the classroom next door. Tom had it figured out, and here’s what he taught me.

Stand at the door between classes and greet each individual student by name with a handshake as they walk in the room. It guarantees that every day you’ll have a positive connection with every one of your students. Student having a bad day?  Find our before they act out in class.  When the bell rings, the door closes and you promptly begin class. Students quickly realize if they are late, they don’t get a personal greeting. Try it  – it works!

Start Your New School Year with Rigor and Relevance

start the school year

As a social studies high school teacher, I faced over 25 years of the first day of school. When I first began teaching, I did usual thing – working through the class list (“do you prefer Patrick, or Pat?), a dry recitation of the class rules,  passing out the textbooks. Blah, blah, blah – think of the message it sent to my students.

As my teaching style evolved from the lecture / work sheet model into a more engaged learning environment, I redefined how I wanted to introduce my students to my course. I also came to understand that it was imperative that I get all my students to contribute a few comments to the class during those first few days. Very quickly classes learn which students are the talkers and non-talkers. Once those roles are locked in – it’s very difficult for student for break out of them.

So I did not waste the opening week of school introducing the course – my students solved murder mysteries. I took simplified mysteries and split them into 25-30 clues, each on a single strip of paper. (You can download one of the mysteries and rules from my website.)  I used a random count off to get the kids away from their buddies and into groups of 5-6 students. Each group got a complete set of clues for the mystery. Each student in the group got 4-5 clues that they could not pass around to the other students. They had to share the clues verbally in the group and that guaranteed that every student is a talker on day one.

While the students worked to solve the mystery – I concentrated on learning the student names. After I introduced the mystery, I bet them that by the end of the first class, I could go around the room and recite their names. While they worked on the mystery, I circulated getting to know students and their names. Another message – in this class, we’re all learners.

Over the next few days we would process their problem solving skills, group dynamics, differences between relevant and irrelevant information and introduce the idea of higher-order thinking like analysis, evaluation and creating. We might even have time to try another mystery to see if they got better.

By week two, I got around to passing out the textbooks. But by then I had already introduced them to what was most important about my class.

Summarizing What’s Important with a “How To” Video

Explaining “how to” requires students to research a subject, evaluate what’s important, and create a guide for someone else to follow. It gives them an opportunity to write for an authentic audience and purpose and use skills that rank very high on Bloom’s taxonomy. When we ask students to summarize without giving them an audience and purpose all we are doing is asking them to “guess what the teacher thinks is important.”

A few weeks ago I posted on the great opportunities for students to teach others by creating how to videos. Since then I ‘ve found a great source list of How To video sites at ReadWriteWeb.

The Digital Literacy Debate: Are We Really Reading on the Web?

A new series examining the debate on 21st century literacy skills is beginning at the New York Times See: Literacy Debate: Online, R U Really Reading? by Motoko Rich, July 27, 2008.

As teenagers’ scores on standardized reading tests have declined or stagnated, some argue that the hours spent prowling the Internet are the enemy of reading — diminishing literacy, wrecking attention spans and destroying a precious common culture that exists only through the reading of books. … But others say the Internet has created a new kind of reading, one that schools and society should not discount. The Web inspires teenagers who might otherwise spend most of their leisure time watching television, to read and write. …Clearly, reading in print and on the Internet are different. On paper, text has a predetermined beginning, middle and end, where readers focus for a sustained period on one author’s vision. On the Internet, readers skate through cyberspace at will and, in effect, compose their own beginnings, middles and ends. More Literacy_Debate_Online,_RU_Really Reading?  120KB pdf

Each medium of communications leads us to codify reality in unique ways. For example, oral communication is very mosaic – we communicate not only with words, but gestures, inflections, and tone. Over time we learn to read all these bits of information and merge them into a cohesive message. Print, in contrast, is very lineal. Writing forces our thinking into some sort of conceptual “meat grinder” that sequences our disparate thoughts together. Following rules of grammar and mechanics, we compose our message into the an equivalent of one long “fortune cookie” of text. The skill set needed to “literate” in speech and print very different as are the relative value we place on effective communicators in each media. A similar case could be made for the unique ways we codify reality in graphic novels, film, video, dance, ASL and so on. Searching and reading on the web is not the same as reading a book.

New-readers

The digital literacy debate will continue to rage on, in the meantime educators and parents need to learn more about how the new media are shaping the thinking and perceptions of our children. Students will forge ahead without us. As Carol Jago of the National Council of Teachers of English stated,  “Nobody has taught a single kid to text message. Kids are smart. When they want to do something, schools don’t have to get involved.” 

Note, I last commented on this subject in my post “Is Google Making Us Stupid?”
