More than just Dazzle

I’m in Auckland at the moment for the first New Zealand National IWB Conference.  As some of you may know, I co-authored a book a while back with Mal Lee that was all about IWBs and interactive technology in general, and I learned a fair bit about whiteboards and their various uses in the process of writing that book. I’ve presented at the last three Australian IWB conferences, another in Napier earlier this year, and now this one in Auckland.  Plus, since the book came out I get asked quite a lot to run IWB workshops for schools, where I get to I talk to lots of teachers about the things they do with their IWBs.  (Actually I’ve always talked to lots of teachers about their IWB use, but I think I ask much better questions these days).  All of this has given me – I think – a reasonable perspective on the current state of IWB use, so I just thought I’d blog a couple of reflections about it.

When I first saw an interactive whiteboard, I really wasn’t very impressed with what I saw.  I remember touring through a school in southwest Sydney about 5 years ago that had installed them in every room.  As I wandered around looking at how they were being used, a few thoughts struck me…

  1. I couldn’t see anything special about “the board”. It seemed that everything I saw being done could have been done with just a projector on its own equally as effectively.
  2. There was nothing terribly special or even pedagogically sound about what I saw.  It was mostly just online games and digital “busy work”.
  3. I wondered if these people had given any thought to how much their ongoing costs for replacement projector bulbs would amount to!

Shortly after that, I was asked if I would help develop some digital teaching resources for teachers using IWBs.  I recall it was myself and another teacher who were commissioned to create this package, and I think we had 5 days to work on it, but I spent most of the first three days arguing with her about how stupid some of these whiteboard activity ideas were.  Mind you, I was a high school teacher and she was a primary school teacher, and were both coming at it from completely different paradigms.  Eventually we did come up with some good ideas, but I felt like the process of arguing and questioning the value of the IWB actually brought us to a far clearer realisation about what exactly these IWB things were all about.  Or at least what they could and should be all about.

When I was teaching in Canada, my school adopted Smartboards. I was lucky enough to be selected for the original “pioneer group” of teachers there, and we got some excellent training directly from the trainers at Smart.  Over the last couple of years I’ve read a lot of research papers and blogposts about IWBs, listened to a lot of IWB specific podcasts, watched a lot of teachers work with them, had many, many conversations about them with all sorts of teachers. And, of course, I’ve co-written what has turned out to be a pretty comprehensive book on the subject.

There are still some people who have some pretty negative opinions about IWBs.  They claim that interactive whiteboards are a backward step. Coming from my originally skeptical position, I totally understand the controversy surrounding IWB technology.  However, I also feel like I’m reasonably well qualified to have some sort of considered opinion about them, so here’s a few thoughts…

I feel like the general attitude to IWBs and the approach to using them seems to have matured somewhat over the last 12 months.  In the early days of IWBs, many teachers were clearly impressed with the “wow factor” and were not giving a lot of deep consideration to the actual pedagogy for their more meaningful use or thinking about how they might become seamlessly embedded into the daily routine of teaching and learning. 

These days however, I’m pleased to say that most of the conversations I hear about IWBs seem to have a much more pedagogically focused outlook.  More teachers seem to be thinking intelligently about how they might be used to improve learning, or at least raise the student engagement factor in some sort of sustainable way.  They want to know about how to use the technology to deepen understanding and to promote higher order thinking skills.  They genuinely want to become more proficient in their use, so they can get the technicalities of using them out of the way and focus on the real issues of “how will this help me teach better, and how will this help my students learn better?”

It’s becoming much harder for vendors to dazzle educators with fancy animations and meaningless drag-and-drop activities.  It seems to me that the IWB-using educators I’m meeting these days are much more discriminating and thoughtful about how they use the technology.  They also have a far more suspicious view of outrageous vendor claims about the instant impact an IWB will have on their classrooms.  For way too long, vendors promoted IWBs as though they were some sort of magical panacea for classrooms.  “Just add an IWB to your classroom and student excellence will automatically follow!” seems to be the claim. 

From what I’ve seen lately, that claim is being increasingly seen for the lie that it is.  Intelligent teachers know that while interactive whiteboards might be a powerful addition to their classroom, expecting them to be more than that is just naive.  Great teaching is still the catalyst that makes powerful learning possible, but used wisely, IWBs can certainly enrich that environment.

Using Twitter to develop a PLN

Another article written for Education Technology Australia. Probably not much new in here for regular readers of this blog, but I thought I’d post it just in case anyone found it interesting…

—

Of all the tools to emerge from the Web 2.0 revolution, few are as intriguing as Twitter. When Twitter first appeared in 2006 it was one of those hard to define web tools that, on the surface, sounded silly and trivial. However, in the last few years it has risen to be one of the web’s most powerful simple ideas.

At its best, Twitter is the ultimate real-time communication tool, enabling ideas to spread across the Internet with unprecedented speed and reach. As a mechanism for gaining insight into the “wisdom of the crowds” it has few equals. During the recent elections in Iran for example, Twitter proved its worth as a vehicle for people in Tehran to keep the flow of information going to the outside world, even when official news crews were being silenced and censored by the government. Thanks to Twitter, the truth still had a voice.

At its worst, Twitter can be nothing but an embarrassing parade of personal ephemera, filled with people publicly sharing the most inane and trivial aspects of their lives.

Twitter was created in 2006 as a side project by Odeo Corp, but has since evolved into one of the web’s hottest properties. Thanks to its recent “discovery” by Hollywood stars and TV personalities, Twitter has experienced a massive burst of growth and visibility. It seems that everywhere you turn these days you hear about Twitter, and yet it remains generally misunderstood by most people.

So what exactly is Twitter? Think of it as a cross between SMS, email and blogging. Usually referred to as a microblogging service, Twitter enables users to send out short 140 character messages to anyone who chooses to “follow” them. Some people have thousands of “followers” reading their updates, or “tweets”, each supposedly answering the simple question “what are you doing?” Followers have the opportunity to engage in dialog with those they follow by sending a public reply – usually called an at-reply due to the Twitter convention of prefixing their response with an @ symbol – or to reply in private with a direct message, usually called a DM. These short 140 character bursts of text between individuals are generating thousands of simultaneous conversations that anyone can take part in.

Originally the domain of the geeky elite, Twitter has expanded its reach into far more mainstream uses. Celebrities are using Twitter to build their fan base. Marketers are finding Twitter powerful for spreading the word about new products and services. Companies monitor the flow of Twitter messages to see what people are saying about them. Politicians are using Twitter to converse with their constituents. It seems that many people are finding plenty of uses for a tool that lets you quickly and simply communicate you are doing.

But what about educators? What possible uses could teachers find for a tool like Twitter? As it turns out, quite a few.

The trend in professional development for educators is towards the development of a Personal Learning Network, or PLN. PLNs utilise the principle of just-in-time learning by encouraging teachers to surround themselves with others who share similar interests or knowledge. A teacher with a well developed PLN is able to turn to her network of colleagues to share ideas, ask questions, get feedback or find an audience. Many teachers have limited opportunities to surround themselves with like-minded others, either because they work in a small school, teach a niche subject, or simply don’t have access to people who think like them. Consequently, it becomes easy for many educators to feel as though they work in a vacuum, with limited opportunities to discuss ideas or get advice from others. Attending conferences or professional development days can be really useful, but these are usually limited to a few days a year.

By using a tool like Twitter to surround themselves with a network of other educators, and then using these networks to engage in ongoing conversations about teaching and learning, any teacher can have access to the “brains trust” of a larger groups of people at any time. Twitter can play a key role in connecting people together to form these personal learning networks.

Anyone can sign up for a free Twitter account at www.twitter.com. Upon joining Twitter, they will be provided with a list of suggestions for people to follow, but these are usually a random assortment of Hollywood celebrities, companies, politicians, musicians and sports stars… not exactly the right foundation for building an education-based personal learning network! Of course, there are no real rules about who you can and can’t follow – follow whoever you want – but remember that if you want to develop a Twitter network with an education focus then you should begin by following people who are already engaged in these conversations. During the signup process, Twitter will also offer to search your email address book to see if any of the people you know are currently using the service. If it finds any, it will offer to add them to your network.

The best way to start building your network is by following someone you already know and seeing who they follow. Clicking on the grid of icons will lead you to the Twitter pages of others, where you can read their bio, their latest tweets and see who else they follow. Once you find someone that sounds interesting to you, just click the “Follow” button to add them to your network. The real value of a Twitter network does not become apparent until you add at least 40 to 50 people, so continue this process of finding people to follow until you build this critical mass. When you follow someone, they receive an email notification about it and can then decide whether they want to follow you back or not. Don’t be to concerned or offended if someone does not follow you back immediately.

The other way to quickly develop a network of people is by using a list such as that found at http://twitter4teachers.pbworks.com. This list, built using a wiki by Gina Hartman, a teacher from Missouri, contains organised lists of teachers who use Twitter to help make the process of building your network simpler. Similar lists exist at http://twitterpacks.pbworks.com, where you can search for all sorts of interesting Twitter-using communities. Another excellent list of education professionals to follow online can be found at http://c4lpt.co.uk/connexions. Take some time to explore these lists and you’ll soon find plenty of interesting, relevant people to add to your network.

Once you begin to build this network around you, you’ll find a constant stream of new ideas, new links and new tools to explore. People in your network will be sharing thoughts with each other, having conversations that you can join or simply eavesdrop on. With the right group of people in your network you will be exposed to more new ideas and suggestions each day than you would normally get in a whole year of regular PD. You will have a team of people around you that you can ask questions and get suggestions from. You can tap their collective wisdom. You can get perspective from outside your regular contacts. You can find people to collaborate with. You can find an audience for student projects. Having a global network of people surrounding you, enabled by Twitter, opens up a world of professional possibilities for your own learning and sharing. You will get a much better feel for the pulse of the web.

Unlike social networking sites like Myspace and Facebook, Twitter has not become hugely popular with school-aged users and it remains somewhat of a place for “grown-ups”. Many specialist communities have adopted Twitter for their own uses, and education is one field which seems to have truly grasped the value that the service can bring to their community. Because Twitter is driven by short, to-the-point messages, it seems to be a place where content and conversation is valued. If you find particular users talking about trivial things that don’t interest you, or “overtweeting” – tweeting so often that it simply becomes annoying – you always have the option to unfollow them. You have complete control over who you want in your network. It is a very democratic environment… if people add value they find followers.

Once you start to use it more you will probably find the Twitter website a fairly inconvenient way to use the service, so there are some excellent Twitter clients – specialised software for using Twitter in an easier, more integrated way from your computer or mobile phone. There are many to choose from, but TweetDeck, Twhirl, Tweetie and Nambu are very popular. There are also plenty of Twitter clients tools that run on mobile phones – mobile versions of TweetDeck and Nambu for the iPhone, or Gravity for Nokia phones, enabling you to tweet from wherever you are.

If you haven’t tried it yet, give Twitter a go. Try using it to build a personal learning network of people you find interesting. You might be pleasantly surprised as just how powerful this simple idea can be.

How Tagging Solves the Problem of the Physical World

This article was written for Education Technology Solutions magazine, but I’ve also republished it here, because I can.

—

One of the unavoidable buzzwords of Web 2.0 is the term “tag”.  Everywhere you look online you come across the term, and everything from photos to news articles to blogposts are getting “tagged”.

But what exactly are “tags” and why are they such a big deal these days? To understand the importance of tagging, first let’s consider the problem that tagging sets out to solve.

There was a time when everything in our lives existed only in the physical world.  Books sat on shelves. Photos were in photo albums. Music was stored on CDs. Life was simple.  If you wanted to find that photo of your sister-in-law Wendy wearing a silly hat at last year’s family Christmas party you simply went to the family photo album and flicked through the pages till you found it.  The photo was a real physical object that existed in one real physical location.

Storing a photo in a family photo album seems pretty obvious, but the problem is that this method of storing, finding and accessing an object does not scale well. If we had to find that one photo from a room full of photo albums the problem becomes a little trickier. The ability to quickly find something becomes exponentially more difficult as the size of the collection of objects increases, and also as the object becomes more miscellaneous.

For example, have you ever wandered the aisles of a supermarket trying to find a particular item, only to discover that it was located in a completely different section to the one you expected it to be in?  The more obvious items are easy – milk is in the diary section, steak is in the meat section and frozen beans are in the frozen vegetable section of the freezer.  Easy. But as the item gets more unusual or miscellaneous, it gets harder to know just where the supermarket has cataloged it on their shelves.  We expect to find tinned fruit salad in the canned goods section of the supermarket, but if you like to put fruit salad on your breakfast cereal it would also be handy to have it located in the cereal aisle, in fact it might even boost sales of the tinned fruit.  Both of these locations actually make sense, although the people responsible for stacking the supermarket shelves ultimately have to make a decision and put it in only one location.

Why don’t they just put items in every location where it makes sense?  Why not put items in multiple places, making it easier for people to find them no matter where they look?

Of course, the answer is due to the physical limitations of the world we live in.  Supermarkets simply don’t have the physical space to put items in multiple locations. Even if they did, trying to shop in a store that had lots of products in lots of places would end up as a confusing mess.  The idea makes sense, but it doesn’t really work very well in the physical world we live in.  In the physical world these limitations force us to make decisions about the “best” location for every real object.

In an digital world, these limitations of physical objects don’t exist.

Take bookmarking for example. When you browse the Web you often find useful websites that you may want to revisit again, and all web browsing software offers the ability to “bookmark” or “favorite” these sites to make them easy to get back to.  We typically find an interesting website, click the Bookmark menu and choose “Save as Bookmark”… when we want to go back to that webpage, we look through our list of bookmarks and select the one we want from that list

As our collection of bookmarks grows into a long random list most of us eventually work out that we need to organise them somehow, so we start putting our bookmarks into collection, or folders.  Sites that are personal might go into a folder called “Personal” while sites that are useful for work are dropped into a folder called “Work”. Again, as your collection grows you’ll probably find that you need to be more specific, so you end up with a collection of folders designated with names like “IWB Resources”, “Maths Resources” or “Games”.  You can keep adding folders, bookmarking new websites into existing folders or adding more folders if appropriate ones don’t yet exist. Things are nicely organised now, right?

Sort of.

What happens when you find a really good Maths game resource that works well on an IWB? Do you put it in the IWB Resources folder, the Maths resources folder or the Games folder? The truth is, it makes sense to put it in all of these.  You could always bookmark it three times, once in each folder, but as your collection grows, you realise that this could get pretty unwieldy and complicated.  You could just make a decision and put it in one folder only, but unless you remember which one it went into, you may never find it when you need it. You are now facing the same problem as the supermarket shelf stackers; you have an object – in this case a website – that makes sense in more than one place, but to put it in multiple locations is just going to be confusing and hard to maintain.

The solution is to use tags.  Tags are like keywords that get attached to a resource and used as search terms when you want to retrieve it.  A resource can have as many tags as you like, in fact the more tags the better.  It’s a little bit like saving the resource in multiple locations, except instead of having to actually place it in all those locations, the tags simply create an association with those locations.
Tagging works because the tagged objects are digital, not physical. In the digital world, things don’t ever really “exist” anywhere, so having them “exist” in multiple locations becomes a non-issue. A search for all the websites tagged with the word “maths” will generate a list of every website with the tag “maths” attached to it. The search doesn’t care where each website is physically located.  The only thing that matters is that every website has the keyword – or tag – “maths” attached to it.

The fact that the same site might be both an IWB resource and also a game is largely irrelevant.  If a tag search was done for websites tagged with the word “game”, then the IWB-based maths game website would still be in the list.  The beauty of tags is that they allow resources to be cataloged in any ways that make sense.  A decision does not need to be made about the best way to catalog an item, because it can be cataloged in any and every way that makes sense.

In a digital world, photos that are tagged with keywords can be easily retrieved from a huge collection just by looking for one or more keywords. So, if that photo of your sister-in-law was tagged with words like “christmas”, “sillyhat” and “wendy”, then any of these search terms would find the photos.  Someone searching for the word “christmas” would find it, along with every other photo in the collection tagged with the word “christmas”.  Searching with the term “wendy” would find all the photos of Wendy, and a search using “sillyhat” would find any photo tagged with that term, regardless of who was wearing the silly hat.  To find the specific photo you were after, a search using several of these tags would quickly narrow down the search to photos of Wendy, at Christmas, wearing a silly hat. Each tag acts like a filter to only show the photos that match the criteria.

Tagging works because computers are really good at quickly searching through massive amounts of data. Getting computers to find things is pretty easy, but tagging adds the necessary “hooks” that the search can latch onto. Without these tags attached to each resource, computers find it difficult to link each resource to the ideas that you wish to associate with them.  The computer might be able to find things quickly, but tagging helps it know how those things relate to YOU. By adding tags to things, you build a collection of metadata around each object that makes it meaningful to you.  It lets you associate those objects to ideas that make personal sense to you.  And as you tag more and more resources, patterns start to emerge that make it even easier to see the semantic nature of that information, further helping you make sense of it.

Tagging is everywhere on the web however if you are new to the idea and want to see tagging in action, two great place to start are www.delicious.com for web bookmarks, and www.flickr.com for digital photography. Searching these sites using tags is a nice easy way to see the real value of tagging as a way to organise massive amounts of information in a digital world.

For more detailed information about tagging and how to use it effectively, take a look a my K12 Online presentation entitled “I Like Delicious Things” at http://vimeo.com/2415647.
