Just found this amazing video interview, conducted by Howard Riengold, with middle school teacher, Meredith Stewart. What a lovely piece of solid gold. Thank you, Howard! Thank you, Meredith!

I just discovered a new tag cloud creator (or word-picture tool) – Tagxedo. This is a free online application that allows you to make word pictures (or clouds) where the most oft-used words appear largest. This is a good way to get a visual “feel” for a particular text chunk, document, or web site.
Tagxedo is similar to Wordle, but much more powerful with many additional capabilities. First off, as you roll over the online Tagxedo with your mouse, the words come to the front and you can make them live links. You can also spin your cloud, choose different themes (many available), select different colors & fonts, and constrain the word-picture by shapes (hearts, ovals, circles). The cloud to the right (made up of my blog’s contents), is made from the same words as the cloud at the top of the page – this time in the shape of a flower. You can structure it so that you skip words (removing unimportant words, like “the”). Apparently, you can also use photos to create the shapes – like this one of Abe Lincoln. I haven’t tried that yet, but it certainly presents some interesting possibilities. Once you’re created your Tagxedo cloud, you can save it as an image – in both jpg and png formats – at a range of resolutions. What fun.
Students aren’t as proficient as we think they are with online tools….they don’t know how to download a photo, they’ve never edited a wiki, they don’t understand intellectual property.
As teachers, we need help sorting out what’s the right tool for the job and which – if any – of the options is worth our time.
What I don’t evaluate or grade, my students won’t do.
Raise your hand if you know what that funny looking black and white thing is on the brick wall above. That is a QR code. What, you may well ask, are QR codes? QR = Quick Response. A bit of an unknown here in the U.S., but they are all over Japan (and have been for years) and are starting to make headway in Europe.
Think of them as fancy, 2D bar codes. First introduced in 1994, these are matrix codes that, when scanned, redirect you to whatever digital information has been encoded there (urls, whatever). They are a very efficient and reliable way to provide a url in non-networked situation – e.g on paper, on a billboard, on a painted surface – anywhere. A QR code can hold a lot of information – up to 4,000 characters. Even a simple jpeg can be scanned into a QR code, faxed, and then read at the other end.
But how are these QR codes read? With any one of a number of free QR code readers – free apps that can be downloaded to a cell phone. In fact, most new cell phones come already pre-loaded with QR code readers. Once you have the reader, you just aim the phone’s camera at the QR code, the camera registers the data, and redirects you to whatever information was programmed into the code. If it was a url, your phone will kick start the browser and take you to the desired web site. Bee Tag is the reader that I use, and i-nigma is a very popular one. Here’s a very simple, short video, showing you how it’s done.
And how do you generate these QR codes? With any one of a number of free QR code generation sites. Like Kaywa or QRStuff. You just enter the url (or other data) you want to encode and the site spawns a printable QR code for you. Voila!
Here’s what QR codes look like. This one, by the way, is embedded with all of my contact information, the url for this blog, my skype and twitter IDs. I use it on my business card.
So, how might they be used in teaching? At the simplest level, you could include them in a printed worksheet (for homework or on an exam). Another idea would be to use small QR code labels in a lab – print them on ready-to-peel labels or tape them onto basic lab equipment (microscopes, glassware, sensors, binoculars, cabinets or drawers). The codes would would lead students to teaching videos or amplified safety information. QR codes printed on labels could be applied to bones or preserved specimens to lead students to further information or investigation. Perhaps you could assign students the project of creating these QR codes for your lab supplies and equipment? Another possibility might be to use QR codes in an assessment – they go to the pre-determined site, watch a video or an animation, then answer questions about it. Use them for orienteering in an outdoor education course or on a field trip. The QR codes could connect to maps or destinations on Google Earth. Have students create their own QR codes that they submit as an assignment. Maybe a “get-to-know-the-lab” scavenger hunt at the beginning of the year? Maybe have them printed on t-shirts as end of the year prizes? Put them on business cards, luggage tags or make temporary tatoos out of them! Just for fun, check out this video of a summer project, sponsored by a Japanese company to make a dramatically scaled QR code, out of sand.
What ideas do you have for using QR codes?
- A set of Darwin bookmarks on my Diigo page.
I’m becoming increasingly fond of electronic bookmarking services like Delicious and Diigo. Diigo, in particular, has become my bookmarking tool of choice, because of their collaboration tools. You can highlight, add sticky notes, search, make lists, and create groups. Here’s a 4-minute video showing how the Diigo collaboration tools work.
But the best way to get a feel for what you can do, is to take a look at an annotated article. Here’s an example, from Will Richardson. What he’s done is to bookmark an article (from the Wall Street Journal) in Diigo, highlight key passages and then embellish with comments using their sticky notes feature. When you’re ready, Diigo spawns a unique URL to your annotated version of the article. When others use this Diigo-created link to navigate to the article, they see your highlights and comments (roll over the highlighted comments and his sticky notes appear). In addition to reading the bookmarker’s comments, the reader can comment right back – agreeing or disagreeing with you, asking further questions, seeking clarification. With time, you can imagine a whole conversation started (and recorded) around an online article.
What an interesting idea to try with science students. You could start by bookmarking an appropriate (pick a fairly straightforward one) scientific journal article and highlight it to point out the key elements. You can add your own comments (with the sticky notes) to make points that support what you’ve been talking about in class or lab. For instance, “here’s the researcher’s hypothesis” or “notice the basic structural elements of the paper” – or ask them a question “which is the control group?”. When students access the url you provide, they will see your annotations and can add their own.
Let me know if you try it – would love to see a collection of Diigo-marked articles with teacher-to-student conversations.
“We are living in the middle of the largest increase in expressive capability in the history of the human race.” Clay Shirky
I can’t help but notice the startling contrast between the world inside school these days and the world outside of school. Outside of schools, students are talking about music they’re producing, online communities they are part of, conversations they’re having online with people at a distance, and sharing, sharing, sharing.
Inside school? Well, not so much. Inside school looks pretty much the same way it has for a very, very long time.
The National School Board Association recently published results of three surveys regarding social networking and I was not surprised to learn, in a recent THE Journal article, that 52% of all districts interviewed prohibited any use of social networking sites in school. But here’s the kicker – “almost 60% of students who use social networking talk about education topics online and, surprisingly, more than 50% talk specifically about schoolwork.”
There’s a new literacy out there and, you know what? …it’s happening with or without our schools. But just think for a minute how much better it might be if our teachers, administrators, and school resources were supporting and guiding that literacy journey that our students are taking without us. Just think what teachers could contribute. Yes, students are pretty facile with all of this new media, but there’s still so much they need to know. For example, students need to know how to determine the veracity of a web site (and find out who owns the domain), how to safely navigate an online social network, how to make good judgments about what they post online, how to edit a wikipedia entry, how to navigate the sea of information available to them, how to use of the creative commons, how to curate their own work, how to connect with experts and peers – how to embed, share, mash-up, remix, and animate.
The federal No Child Left Behind Act and standardized state curricula and assessments don’t reflect these literacies. There’s no doubt about the fact that NCLB and the way student achievement is measured has had a strong influence on daily life in the classroom. By aligning our schools along the narrow band of what can be evaluated in a high stakes exam, we fail to assign value to the new knowledge and skills that our youth need to become effective participants in a global, networked environment. It’s time for our schools to teach and foster responsible student mastery of new literacy forms. That doesn’t mean throwing away the old ones – couldn’t we augment them with the new literacies? We have a responsibility to teach students to critically understand and responsibly use these new forms of media – and in order to do that, we need to understand them ourselves.
Web 2.0 is an ideal platform for this kind of participatory learning. These tools help us to reach out to others, join in the conversation, creatively express ourselves, and find our teachers. As Chris Dede says, we want students to not just be problem solvers, but problem finders – out there, working it, finding fresh areas for investigation.
