Sequencing – An Essential Summarizing Skill

I’ve been experimenting with Dipity, a new website that allows you to build interactive timelines. Open a free account, create a new topic, and then upload text and images (from a file.) You can view your topic as an timeline or flipbook. You can even geocode your events and view the project as a map. You are allowed to set permissions for viewers and editing rights.  I created a sample timeline “How did the roles and rights of women change at the turn of the 20th century?”  Note: One drawback for classroom use – banner ads appear on the page and  I can’t vouch for what might show up.

Dipity allows you to configure the display of the topic and copy and paste the embed code into your page. You should be able to click the embedded image below.

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.

Wordle1

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.

Wordle4

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."

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?”

Students Can Create Videos to Teach Us “How To”

There’s an emerging genre of internet videos that fall into the category of “how to’s.” Lots of folks are offering up instructional guides for how to do everything imaginable from How to Chill a Coke in 2 Minutes to How to Fold a Towel.

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.

If you want to get your students writing and shooting these videos here’s some suggestions:

1. Get the new Flip Ultra video camera – remarkably easy to use and only $114 at Amazon. Works with Mac or PC. I’ve been using one for a few months and I’m impressed with the sound and image quality and the simplicity of use.

2. Have students take a look at this ingenious “how to” done by Common Craft – no elaborate props or on-screen talent required. The Flip camera won’t be able to shoot as closely as the Common Craft video below, but students can easily recreate the look on a larger scale using the classroom white board and the optional Flip Ultra tripod ($14 at Amazon).

3. Post the video to TeacherTube – a safe alternative to YouTube.

OK – time to make a movie!

Note on editing. The Flip video comes with its own software that works with Mac or PC. Ingeniously, the software resides on the camera and works anytime you plug the Flip USB into a computer.� The Flip video files are created in an AVI format that can be edited on a PC using software like MovieMaker. Mac iMovie won’t accept the Flip video AVI format directly, but you can convert an AVI file to a (iMovie-friendly) m4v file format using free iSquint software. Students can design, shoot and edit the video, then do a voice over. That way they can focus on the visual message separately from the audio message.

8/08 Update: The latest version of Flip video software will allow direct import of files into Mac iMovie!
