Guest Blogging in the U.S.A.

The following post is something I wrote as a guest blogger on Wes Fryer's popular blog, Moving at the Speed of Creativity. My contribution will be posted on June 21.

The satisfaction to be derived from success in a great constructive enterprise is one of the most massive that life has to offer.

-Bertrand Russell

The first time I remember “creating” something for a school assignment was in 3rd grade. Up until this point, what I remember about school involved completing worksheets at my desk, reading from various texts in front of the whole class, and being placed in groups based on my ability in math and reading. This all changed in Mr. Beaver’s class, my 3rd grade teacher.

Mr. Beaver involved his students in various activities and challenges, most of which required us to build something with materials we found at home. He would come into class one day and toss out some ambiguous statement as if it were a hook with a worm: “My daughter bought a kite this weekend, and it works pretty well. I wonder if she could have built a kite out of supplies she found at home. Nah, probably not. That’s too hard for someone her age.” This was just enough for a few of us to go home and try to prove him wrong. During the school year, we had several projects that involved creating things: electromagnets, dioramas, kites, maps. For a kid who liked making stuff anyway, it was a fun year in school.

This experience probably planted the seed in my mind that projects are a fun and engaging way to learn. As a teacher, I tried to implement several different projects throughout the year, and now I spend a fair amount of time helping other teachers design and implement student projects in their classrooms.

Most of the work I have done in recent years has centered around digital media: teachers helping students combine images, audio, video and/or text to express their learning through such products as digital stories, documentaries, podcasts, virtual museums and comics. More recently, however, I have been involved in projects that cross over from digital media to physical media, otherwise known as digital fabrication or desktop engineering.

The focus of this initiative, under the direction of Glen Bull at the University of Virginia, is to teach students to apply math, science, engineering and technology skills and concepts to real-world problems. Students create digital models of objects such as electrical circuits, windmills, and gears, print and cut them using special equipment, then construct the components into a physical object. This short video describes the process of digital fabrication.

The concept of creating virtual 3D representations of objects before creating the physical object is not new. Many of the things we use everyday - cars, homes, buildings, city plans, electronics, and aircraft - were first designed and tested in a virtual environment before the physical object was ever built. Similar to storyboarding in movies and game design, virtual models help designers test and troubleshoot their products without making potentially costly mistakes that waste resources. As teachers, we want our students to be problem solvers and identify areas for improvement early in a process rather than later.

An integral part of this initiative has been training teachers - both in-service and preservice - how to integrate engineering and fabrication activities into their existing curriculum. Our research has confirmed a line of previous studies that many in-service and preservice teachers, especially at the elementary level, lack confidence when it comes to teaching math and science. This can be a barrier when it comes to encouraging teachers to create engineering design projects for their students. In response to this problem, we have been replicating engineering design projects being done with 4-5 grade students in Virginia with preservice teachers in North Texas.

If you are interested in reading examples about digital fabrication in a teacher education course, I have provided a few for you here:

• Teaching Virtual Design in a Physical World
• Implementing Digital Fabrication
• Digital Fabrication, take two

The University of Virginia also has a wealth of resources on this topic, which can be accessed for free on the Make to Learn website. Most of these activities do not require a Silhouette cutting machine and have been successfully implemented in some classrooms with nothing more than scissors. I have also found some excellent activities at robives.com, but I have yet to try any of them with students or teachers.

My hope is that sharing some of the work being done in the area of desktop engineering with a larger audience will generate some interest in doing this type of work in the classroom. This initiative is in its infancy, yet it has already attracted quite a bit of attention and buy-in from several school districts, universities and the National Science Foundation. The need for our students to be creators, thinkers and innovators has never been greater, and there seems to be no better way to foster these qualities than to engage students in activities that require creativity, thinking and innovation. Students already have a reputation for being massive consumers of digital media and other technological innovations, and they are one of the largest groups to create and share digital content. Now, with the emergence of desktop engineering we have the resources at our fingertips to help them discover the relationship between virtual and physical media and further explore what it means to play with media.

Why digital text is here stay

As if anyone would even argue this point, I just had a flash that served as one more reminder why digital text is here to stay. This is also why The Cloud is here to stay, and why eReaders are here to stay, and why the discipline of close reading is here to stay. Here's what happened.

I was crafting an e-mail to a friend about a possible digital media study this upcoming fall. In my message, I decided to mention Jonah Lehrer's book ... again. Have I told you about his book, Imagine, lately? Do you need the hyperlink so you can buy it? Am I a sycophant yet? Anyway, there was a phrase from his book that I wanted to use (i.e., claim as my own), but I couldn't remember it. I reached to get my Kindle, and realized it was at home, as are all of my other devices that have this book on it. So, I looked up Kindle on Google, and found out they have a Cloud Reader for computers. Why wouldn't they? I mean, Amazon can sync my other devices so that when I put one down and pick up another later on, I start reading right where I left off. In a matter of 5 or so clicks, I was looking at Lehrer's book at the exact place where I stopped reading last night. I located the phrase (meta-idea), and went right back to my e-mail. Actually, I came right to my blog, then I will get back to my e-mail ... after lunch.

This kind of thing was not even possible a few years ago. If I needed to look at something in a book, I had to either bring the book with me or wait until I got home, to my office, etc. Now I have every book I own (in digital format) right in front of me whenever I need to look something up. I don't think I will ever buy another printed book again. I'm sure publishers will still send me copies of books to review, but if they ever give me the option, I want the eBook. It's important to note, I still had to read the eBook. If I want to make a note, I have to actually make the note. If something in one book makes me think of something in another book, I have to be disciplined enough to write it down before I forget. The eBook (or any digital media, for that matter) does not do the thinking for you, but boy oh boy, does it change the way I approach my scholarship. I love the Web because I find all kinds of resources I never knew existed, but what I really love is to be able to reference those resources I have already read, thought about, re-read, took notes on, and integrated into my existing knowledge base. The perfect storm of taking the time to sit still and read something, mixed with ubiquitous access when I can't remember a phrase or term or quotation. It's the epitome of distributed cognition, to me.

Oh, and my back doesn't hurt anymore from lugging around all those books.

Podcasting and Learning

I've been orbiting and occupying this big ol' Ed Techy world for quite a long time. So, I've read countless papers, proposals, articles, and chapters on "Why my media is better for learning than your media." I've studied this from a cognitive, social, motivational, and developmental perspective, and I am still not convinced that one medium is better for learning than any other. I do believe that all media have different affordances that make them better-suited for certain contexts, learning styles or learning tasks. Needless to say, I've done (and continue to do) my homework  on this one, and I get a little annoyed when people who just perhaps haven't done as much homework on this topic make blanket statements like this one:

 A new study found that students who listen to lectures on podcasts test better than those who listen in class. (You can read the entire article here.)

The "new study" in question is taken from a 2009 article in New Scientist, and it's reporting on a study done in the same year by Dani McKinney. I found these links in a 2012 blog post by Michael Hyatt. My issue is not with bloggers quoting bloggers quoting bloggers, some of whom don't understand educational technology research. The problem I have with this quote, and those like it, is that it is stated as if this were "proven" fact. Here are some things to consider when reading results from this type of research:

1. Learning is complex and influenced by many, many factors: motivation, engagement, prior knowledge, environment, aptitude AND delivery method. To say that students who listen to a podcast at home will score better on a test than those who come to class and listen to the lecture is absurd. This can lead to all kinds of misconceptions about learning, multi-tasking, learning styles and media. "You can learn astrophysics while washing the dishes and updating your Facebook status!"
2. Most educational technology research studies have a long list of limitations. The findings are almost always limited to the study in question, with some suggestions on how to scale it up or replicate the results. This is called "job security" for us academic types.
3. Teacher-created exams may not be the best measure for student learning. Sure, they're great for assigning grades, but they are often mismatched with the learning objectives, and if they are multiple choice, there's a chance the students could guess and get the right answer. The test items may also be written in such a way that it is easy to eliminate answer choices and choose the right one without really knowing the material. I did not read the entire research article, so I will not make any judgments about this instructor's exam.

Online and hybrid learning environments are here to stay, and the research into best practices and learning outcomes for this model of teaching will only get broader and better. Studies such as the one I reference above are an important part in this process and must be done. Any research study should produce more questions than answers, which this one obviously did (Do podcast lectures have the same effect over an entire semester?) But please, if you are going to quote studies like this, look at the original research article and temper your statements with a qualifier or two. Michael Hyatt and Mile Elgan have thousands and thousands of readers. If I go back and read this tonight, I will have one. People believe what they read, and they especially believe what they read when they WANT to believe it. If you want to do better on tests, or learn something new, try the time-tested strategy of applying yourself and taking ownership of your learning. Don't expect media, podcasts or otherwise, to do for you what you aren't willing to do for yourself.

Wikispaces: One-stop shopping for digital learning

In the past several years, I have come to rely on Web-based website builders quite extensively in my teaching. I typically use Google Sites for the bulk of my Web content with my classes, and it has always been very reliable. I have noticed lately that the editor doesn't always load in the newest versions of Firefox. This isn't a big deal because I can jump over to Safari and finish whatever edits I need to do.

Anyway, what started as a way to write lesson plans without having to move files with me wherever I went has evolved into a complete lecture management tool. I started using SeedWiki circa. 2005 because I found myself planning my lectures at odd times, using a host of different computers. Using a wiki was a perfect solution because I could log in from anywhere and pick up where I had left off. I also liked the wiki because I could paste links and other resources directly into the page. It was a great tool.

Eventually, I started giving my class the link to my lecture notes in SeedWiki, and it wasn't long before I was using the wiki as the hub to my class meetings. I got this idea, in part, from someone else, and though I have switched tools I still use this method for managing class meetings. Some of the basics methods that I use a wiki for include:

• Time management: I would organize each section of the class meeting using cells in a table, including the amount of time I thought we would spend on each section. Each section of the class meeting has relevant links, embedded videos, documents, etc.
• Collaborative Learning: Keeping track of group work and collaborative learning can be a nightmare. One area of my teaching that I noticed was in serious need of improvement was keeping the class on track during group discussions. We've all seen this technique used, and it did not come naturally to me. What I noticed in many instances was that the students would spend about 60 seconds discussing the topic, then they would digress into conversation and have nothing to show for their work. Essentially, group discussions lacked accountability and there was no incentive for staying on task. What I began to do, and do to this day, is determine ahead of time how many groups the class would be divided into and create that many pages as part of the class wiki. Each group would then summarize their discussion on the assigned page. I was able to get creative too, throwing in such tasks as finding a random picture on the web, or finding a movie clip that corresponded to their main idea. As soon as the group clicked save, I was able to display their summary to the rest of the class. I had a built-in record of what each group talked about, and because anyone could edit the page, no sign-in was required.
• Lecture Archive: Because everything that we covered, as well as what we did in class, was saved to the wiki for that day, I had a detailed archive of the class meeting. More detailed than I could have created on my own because the class helped me do it. So, when a student would come to class and ask that question that all professors love to hear ("Did we cover anything important last week?"), I could point them to the wiki and tell them that EVERYTHING on the page for that day is important.

About the time that SeedWiki went under, Google Sites (which used to be JotSpot) came around. I was already a big Gmail and Google Docs user at this point, so it made sense to start using Google Sites to manage my lecture notes. The tool itself is very stable and easy to use, but it was not ideal for collaborative learning. Students had to have Google Account and be added one-by-one to the Site before they could log in and participate in the learning activities. This may not sound like a big deal, but there were just enough moving parts that it became a nuisance. Remember, college students are basically high school students with no curfew and more access to beer, and many of them are not good at keeping track of their information. Just to give my students permission to co-edit the class Site, they had to:

1. Open a Google Account
2. Send me the e-mail address they used to open the Google Account
3. Respond to my invitation to join the class Google Site
4. Remember their log in information

When you go to start a class activity and half the class can't access the Site, it gets pretty frustrating. UVa eventually moved to Google Apps for student e-mail accounts, so this reduced some of the friction, but it was still very clunky. In Google Sites' defense, I don't think they ever intended for the tool to be used in this way, and restricting editing access to only those with permission is a security measure.

Recently, I rediscovered Wikispaces, and I think the tool has come along to point where I will start using it exclusively for all of my lecture management needs. I typically use Wikispaces about twice per semester with each of my classes, but I am starting to see how it is much more effective than Google Sites for use in a learning environment. First of all, the teacher can add users to a wiki in bulk. All you do is create  a spreadsheet with usernames and passwords, and upload it to the wiki. Students then have access to the wiki, and they didn't have to sign up or respond to a confirmation e-mail. This option is superior to making the wiki editable by anyone, as you will see later.

Second, you can create Projects within the wiki. These projects are partitioned off from the rest of wiki, making it much easier to manage each activity. Otherwise, the list of your wiki's pages gets to be pretty burdensome and hard to manage. Every time you create a new project, you can drag-n-drop the names of students into different teams, or you can let Wikispaces randomly assign students to teams. This is great for mixing up student groupings and getting students out of their comfort zones. The alternative is letting the students always pick their own groups and essentially work with the same people all semester.

Finally, there is a Discussion tab for each page, which you can use in several different ways. You can have students follow up with group projects by discussing key questions in a back channel. I haven't used this particular feature much, but I plan on using it more.

There are many reasons to use a wiki to manage your class meetings, some of which I have discussed here. What are some other ways you have used a wiki as part of your teaching?

The 15-minute Experiment

One tool I have used with students for several years is a wiki. I have personally used wikis for group work, class websites and digital portfolios. However, I have had a hard time coming up with a good activities for my students that really demonstrate the affordances of a wiki (group editing, version history, comments and discussion, etc.) beyond the ability to just create a web page. In fact, my experiences were always similar to Melissa Cole, who had a lot of great ideas for using a wiki in her class but struggled to get buy-in from her class. I have had the same problem in the past, where I would set up a semester-long collaborative project for students to build a collective knowledge base. These projects always started out strong before interest fizzled after a few weeks. One interesting piece from Cole's article was the brief taxonomy of wiki usage, taken from Tonkin (2005):

1. Single-user. This allows individual students to write and edit their own thoughts and is useful for revision and monitoring changes in understanding over time.
2. Lab book. This enables students to peer review notes kept online by adding, for example, commentary or annotations to existing lecture notes or seminar discussions.
3. Collaborative writing. This can be used by a team for joint research such as a group project, essay or presentation.
4. Creating a topical knowledge repository for a module cohort. Through collaborative entries students create course content that supplements and extends delivered material.

I don't think this list is exhaustive, but it got me to thinking. How could I show my students the power of collective knowledge without giving them a project that would drag on forever, while harnessing knowledge each student currently possessed?

Well, I came up with the following idea:

Imagine you were each asked to speak to a group of students new to UNT about tips for being successful in their first semester. In other words, what do you wish you had known as an incoming student? Chances are you could come up with several good tips. But what would happen if three or four of you collaborated on the same talk? You would probably be able to come up with an even better list of suggestions for incoming students. What you will do in the next 15 minutes is collectively tap into your knowledge and experience and provide incoming students with a knowledge base that might be helpful to their transition to UNT (assuming they take your advice).

The result was this wiki, which I created using WikiSpaces. The end result is not totally impressive, and you can see that some of the students took this opportunity to be kind of silly (which I can relate to ... I was always that kid in the class). But what was interesting was the reaction from many of the students when we debriefed about this activity. For most of them, they got it. They were able to see in a  short amount of time that many people can collectively put their heads together and create something useful (e.g., Wikipedia, though that experiment has taken many years to create).

On the technical side, there was quite a lot of work I had to do beforehand to make this experiment truly 15 minutes. Here is the rundown:

1. Set up the wiki
2. I took advantage of the free teacher upgrade, which allowed me to add users in bulk. This takes about a day to do, since wikispaces wants to verify your .edu or k12 e-mail address.
3. Created a CSV file with a username and password for each of my students.
4. Uploaded the file and created the student accounts.
5. Distributed the usernames and passwords to my class (via Moodle)

I demonstrated this process to the class as well, in case they wanted to try it themselves. I think this is an activity I will include in the future, and I may even have my students edit or add to the existing entries in addition to creating their own. I may have to find a new topic before long if this one becomes saturated, but I think there are still several topics that haven't been addressed.

So, how do you use wikis in your teaching?

Digital Portfolio tools

These days I am thinking a lot about digital portfolios. I have been looking at a lot of them, talking a lot about them and coincidentally, evaluating a lot of them. So that I don't forget all of this by next Fall, I want to put my thoughts down and try to galvanize some of the lessons I have learned this semester. I presented this project at the very beginning of the semester. I think this was overwhelming to some of the students, but my objective was to make sure they knew about their portfolio all semester. I knew some (or many) of them would put this off until the last minute, but I also knew some of the students would appreciate getting an early start. So, I discussed with them the purpose of a portfolio, and we also talked about digital footprints and job searches and other big ideas. Then I showed them some examples of different portfolios from former students using a variety of different tools. The last thing I had them do was open an account with the tool they wanted to use, then send me the URL of their portfolio.

Tool	Pros	Cons
Google Sites	This is an easy tool to use. The interface is simple, and it is easy to find the features you are looking for. There aren't any hidden features or misplaced menus, just a simple set of tools, layouts and themes to choose from. I have used this tool for several years as a way to organize my lectures, and it works great for this. File uploading is especially easy because it is done directly on the page rather than in a dashboard. You can choose to hide the attachments on each page, then create a link to them. Sites builds the menu as you create pages, so the navigation is almost a no-brainer. You can also easily embed videos, slideshows, images and docs from Google's other services. If you a Google apologist, like me, you will find this very easy and convenient to use.	There aren't really that many options when it comes to the look and feel of your Google Site. There are some nice themes, but there is nothing that really stands out or looks flashy (if that is what you are going for). As one of my students put it, "I want my portfolio to look cute." Not exactly my objective when making a portfolio, but that's important to some people. You are able to customize the appearance of the Google Sites, but it takes some time and a little HTML know-how. This is not something a lot of preservice teachers want to dive into.
WikiSpaces	Like Google Sites, this tool is incredibly easy to use. The interface is very similar to Google Sites, and there are a lot of widgets that allow you to add different media to each page. The file manager is quite different than Google Sites, but it is very easy to use. Each page also has a discussion section, so you can center conversations around each page, as well as see the history for the page. This is quite different than Google Sites, where most of this information is hidden. The History tool is nice if I need to see when a page was last edited (as in, after the deadline). I don't make a big deal about this unless it is a major edit. Aside from being a pretty good portfolio tool, WikiSpaces is a great environment for teaching wikis and collaborative knowledge building. To demonstrate the power of collaborative knowledge building, I had my class collectively make this wiki in about 15 minutes.	Like Google Sites, this options for layout and themes are pretty spartan. Some people like this, including me, so it really isn't a con. But the cuteness factor is pretty low. You can customize the website to some degree, but you will have to live with some of the layout features. You will also need to change some of the settings as soon as you create your wiki. The default setting is for anyone to be able to edit the site. If you are using this tool to create a portfolio, you will want to turn that feature off and make yourself the only editor.
Webs	This tool is where you start to trade ease of use for look and feel. The first two tools look very much like something you would expect from a wiki. Webs looks more like a professional website. You have a lot of options in terms of themes and layouts, and they all look very nice.	If you choose to use this tool, be prepared to spend some time messing around with it. I have done a lot of blogging, web design, web mastering, etc., so I was able to make sense of Webs pretty easily. My students, however, struggled with this tool. Once they spent some time with it, the interface started to make sense. I would not recommend this tool to novice web creators. Unless you upgrade to the paid service, you also have to put up with ads on your website. Personally, I wouldn't want ads for reducing belly fat (pictures included!) on my educational portfolio.
Wix	Of all the tools, this one looks the best. Wix is built on Flash, so it looks very professional and, well, flashy. You are able to upload about any kind of file, and Wix has built in widgets to play and display media. The majority of my students were drawn to this tool because they look so good.	Intimidated by new tools? Not familiar with web design? Don't choose this tool. It is NOT for beginners. I had many students choose Wix, and I was able to walk most of them through it. Some of them bailed out and went for Google Sites or WikiSpaces. You will spend a lot of time formatting and figuring out the layout. The end result is a fantastic-looking portfolio, but you will put a lot of sweat equity into it.  The most frustrating feature in this tool, which is true of Webs as well, is embedding a YouTube video. By far, the clunkiest I have EVER seen. This is disappointing considering how well some of the other features work. I guess the developers ran out of steam.
Weebly	This tool is surprisingly easy to use. I am least familiar with it because I didn't have any students choose it. This is how I usually master a web tool, by answering all of their questions. The interface is drag and drop, and even though some of the features (e.g., file uploading) aren't very intuitive, the overall ease of use is a plus.	The free service does not include most of the cool features Weebly has to offer. They tease you with a host of widgets and options, but when you try to add them to your page you get a pop-up telling you they are only available for Premium customers. This might not be a bad idea for someone who wants to keep this portfolio around after the class (or graduation) is over, but I am realistic enough to admit that most of my students drop this project like a hot rock once they have a grade.

So, there is a simple breakdown of tools you can use for a digital portfolio. This is not exhaustive, nor is it very detailed. But there is enough information to get someone started. I will still recommend Google Sites and WikiSpaces to my students, and I am pretty sure they will still choose Webs and Wix. They're like moths to a porch light. The good thing is, the more of them that choose Wix and Webs, the better I will learn them and the better my support will be.

What tools do you use for digital portfolios? Am I missing anything obvious? Let me know!

And the portfolios started rolling in ...

At the beginning of this semester, I wrote about my revised portfolio project that I give my preservice teachers. I was in a portfolio funk, and I needed to try something new before I started resenting this project altogether. Isn't it funny that after you have taught for awhile, you can start talking about your projects as if they are people? Maybe it's just me. I have this metaphor in my mind where each of the assignments are these unfamiliar visitors that enter my classroom at about the same time each semester. I introduce them to my class and talk about them a lot for a week or two, then I give my students a chance to get to know this stranger a little more on their own until he isn't a stranger anymore. Then he leaves and doesn't come around much until the final portfolio is due.

OK. Focus. So, I rolled this assignment out at the beginning of the semester and showed them several examples. Of course, these examples were all based on the old way of doing the portfolio. So, I created a couple of examples on my own using the new way of doing things. Then I proceeded to remind my students very often to get started early on their portfolios and not wait to the last minute. They did anyway. Then I offered a work day where I didn't take attendance but they could come and work on their portfolio and ask questions. Many of them came, some did not. They probably should have. Some students didn't come to the work session but later e-mailed me long lists of questions. Not cool. Then today they turned them in.

Coincidentally, I went to visit my 94-year old grandmother this weekend. She has no Internet and I didn't bother driving to Panera or Starbucks to find a connection. So, during the final crucial moments in the semester for my students when they finally have one last chance to put it all together and make a case for that A they think they deserve, I was silent. I had no idea what kinds of messages I would have when I finally checked my e-mail. I was already constructing responses in my head as the blue bar moved across the screen toward the newly refreshed Gmail inbox. And there it was, a very full inbox ...

But none of the messages were from my students. At least none from the section who had to turn in their projects today. Could this be? I had to know for sure. I went to Moodle, and sure enough a large portion of the class had already turned in the assignment. They did it! I looked at a most of them, and I was beyond pleased at their work. Yes, there were some errors and missing items, but for the most part they looked great.

But the thing that really struck me was the learning that took place in order to get these projects completed. This was no easy task, no matter which tool the students chose. They had to learn how to host files online, and how to make sure a file was readable by anyone who happened to see it. They learned about file sizes and formats, and how to make navigation simple and effective. It was really amazing to see how so many of them stuck with their questions until they figured it out. All things considered, I didn't have one person who expected me to bail him or her out. This is a huge win in my opinion.

So, for now my faith is restored in the power of portfolios. I am left being a little less cynical and little more confident in each student's ability to meet a challenge head on. Yes, I had a couple of them confess that they were up all night finishing, but I can hardly take the blame for that. I will probably never know the full impact of this project, or class, on the bigger picture of their teaching career. For now I am just basking in the satisfaction that they did such a great job and took ownership of their work.

I will follow up in a few days about some of the tools they used to create their portfolios and discuss (at least from the perspective of my class) the pros and cons of each tool as a portfolio management system.

And now that I think of it, I need to have Mr. Portfolio come by more often. Maybe dinner or tea, and he can tell me how his kids are doing ...

Teaching virtual design in a physical world

I first became familiar with the term "digital fabrication" when I was finishing up my dissertation at the University of Virginia. My advisor, Glen Bull, came into my office one day and asked me to watch a demo with a machine he had recently found. I watched with fascination as he created a 3-D model on the computer, printed it as a 2-D net, cut it out in seconds on the CraftROBO machine and folded it into an exact replica of the model on the screen. This was amazing on several fronts:

• It took a matter of minutes to do what would have taken me a whole math lesson (or more) to do with my 4th grade students
• The fold lines were clean and perforated. The physical object actually looked like the model on the screen. For students who have been spoon fed high-quality media since birth, that makes a difference.
• The design was separate from the actual object, which means I could go back to the computer model and make alterations/corrections, then print another one.

That final point is, in my opinion, significant. Let me explain this by making a comparison to the writing process. For children, the act of writing something by hand is laborious. It's labor-intensive to me, and I've been doing it for 35 years. So, when children write something on paper, they want that to be the first and final copy of that particular piece of writing. It's not that they don't like proofreading, editing and revising, but every change they make means another word, sentence, paragraph or page they will have to rewrite. Writing, in addition to being cognitively demanding, is physically demanding on a child's fine-motor skills. Perhaps Malcolm Gladwell is right, that the best people in a certain field aren't always the most naturally gifted, but those in the right place at the right time with the opportunity to perfect their skills. Maybe the best writers in school are those that don't get burned out from the physical act of writing.

The same is true when students are creating things in the classroom. I used to have my students cut out nets from graph paper and fold those shapes into 3-dimensional objects. After spending more than one math lesson to do this,  we could finally get to the learning. This is not considered efficient in the business or medical world, yet in education we just kind of shrug it off and learn to deal with it. And what happened if a student's shape was not exactly symmetrical or was missing a side? Well, they got to be the kid with the lopsided shape. What if I wanted to demonstrate how changing the dimensions of the shape could conserve volume but change surface area? I guess I could have the students cut out a new shape, but there goes another 15-20 minutes. The fact that the media students used to design the object also became the object used to teach the concept was problematic.

This is not as much of a problem when the students design their model on the computer because they can manipulate it without having to physically create another shape. And for all those Piaget and Montessori fans out there, the end result is still a physical object that students can touch and compare. Students learn the basic foundations of rapid prototyping and iterative design, two principals and practices that pretty much define research and development. This is a far cry from the current model of "one and done" projects in schools today.

Below is  a video created by the folks in the Curry School of Education at the University of Virginia who are starting to explore how digital fabrication can be applied in schools to enhance student learning.

I will follow up in a couple of days and explain how I took this concept and turned it into a learning activity for my preservice teachers.

Using Posterous as a class photo archive

I have been playing 5-Picture Charades with my classes for many years. I first came up with the idea (though I'm sure I wasn't the first person to do so) back in the mid-'90's when I was teaching elementary school. I would have my students pick an excerpt from whatever book we happened to be reading, and they would have to act out that scene in 5 pictures. They would then share the images with the class to see if anyone could guess the scene. As you can imagine, the activity was a lot of fun and the students loved it.

In addition to this activity being fun, I also noticed that there was a lot of higher-order thinking going on. Students were having to synthesize passages, evaluate which scenes most accurately characterized their passage, narrow them down to 5 images, decide how to physically portray those 5 essential scenes and ultimately create them. One reason the students loved this activity was because it was challenging, but the kind of challenging that is so much fun you don't realize how much work it actually is.

When I started teaching technology integration courses, I used this activity to teach my students how to capture, edit and publish digital images. I found that they were much more motivated to engage in these  skill-development activities when they were using their own images that they just had a ball creating. I typically gave them fairy tales to act out, but occasionally I would just give them some boundaries (e.g., U.S. History, Literary characters, etc.) and let them pick their own topic. The former category is much easier, but the latter produces much more entertaining image sets. We then use the images to practice image editing, digital storytelling and uploading (which, thanks to Facebook, most of them are already pretty good at).

The only sticky part to this activity every semester was sharing the images with the rest of the class. I tried having them save all of the images to the instructor computer, but it took forever and people ended up sitting around waiting for others to finish. I also tried having the students e-mail the images to me, but that also took forever and sometimes the images were too big to attach (this was before Gmail had such massive attachment allowances). So, it was always tricky getting everyone's images into one place where we could view them.

Well, last semester I got tipped off to Posterous by Wes Fryer, and I decided to use it today for this activity. I created a class account and had the students follow these instructions as soon as they came in from taking their pictures:

Transfer the images from your camera to the computer.

Go to http://posterous.com

Log in using the following credentials

• E-mail:
• Password:

Click on the button that says "Post by web"

Click in the Title field and name it based on your group and section (e.g., Section 001, Group 1)

On the right side of the screen, choose "Upload images, audio, video and docs"

Choose all of your photos at once. You do this by holding down the CTRL key as you click on each photo. Once all 5 images are selected, click Open.

After the photos have uploaded, click Publish.

Have each person in the group save all 5 images to their flash drive

Delete the images from the camera.

Put the camera and all its parts back in the box and return it to me.

I am telling you, I have done this activity many times, and it has never gone as smoothly as it did today. The students came in and got right to work uploading their images to our class Posterous site, and within minutes we were laughing and blurting out trying to guess each group's fairy tale. There was essentially no waiting around or wondering what happened to some of the images. It is almost as if the gallery method of displaying images in Posterous was created just for this activity, and an added bonus is that I now have access to each of these images without having to go around to each computer and copy them to my flash drive.

I definitely recommend Posterous as a place to have students upload images. Flickr groups or Picasa albums are also good, but this is by far the easiest method I have ever used for this purpose.

Learning Management Systems: Hub or Silo?

North Texas has literally been shut down for the past 3 days, with a 4th day impending. We had an arctic front blow in on Monday night, leaving a sheet of ice and snow, and sub-freezing temperatures to keep it intact. Every college, school district, private school and many businesses have been closed since Tuesday.

For the first day of this freeze I was feeling smug because I had already planned an online class for both of my sections of "Computers in the Classroom," at UNT. I had most of the materials ready to go, so it was looking like I would just need to make them available to my class and spend the rest of the day hanging out with my family. I released the materials late Tuesday night, and I didn't think about it again until Wednesday when a student e-mailed to say she couldn't access Moodle. I went to Moodle, and she was right. Nothing.

In addition to cold weather, North Texas was experiencing power shortages caused by over-burdened power plants. In response to this shortage, the state implemented rolling blackouts. We lost power 3 different times on Wednesday for about 20 minutes each, which was only a slight inconvenience. These same rolling blackouts also cut power to Discovery Park, where the Moodle servers are housed. The servers went down, and as of this writing no one has booted them back up. This experience added another chapter to my love/hate relationship (mostly love) with LMS software.

I have been using Learning Management Systems (LMS) since 2005 to help me teach my courses, most of which have been face-to-face. Over the years I have had mostly good experiences, some bad experiences and many teachable moments. I have use Moodle, WebCT, Blackboard, Toolkit (homegrown at UVa), Collab (built at UVa on the Sakai platform) and eCollege. Each of these packages has its own affordances and constraints, and I haven't found any of them to be completely idiot proof. What I have learned is that LMS, no matter which one you are using, make a great hub but a lousy silo.

Silo: a self-contained, secure, private space in which only those with credentials may enter. As in, missle silo.

Hub: a central place that brings together many different pieces from several different places.

People who use LMS as a silo upload everything and post all of their content to the LMS. If they teach more than once section of the same course, they do all of this twice. If a document needs to be updated, they take it down from both sections and upload the updated document. Twice. You get the picture.

People who use LMS as a hub, as I do, keep the content from their course in a place other than the LMS. Rather than uploading files and adding content directly to the LMS, the content is all linked to third-party tools. Here is what this looks like for me: 1) all course documents are in Google Docs and linked to the LMS, 2) all course materials (PDFs, videos, etc.) are hosted on Google Docs or YouTube and linked, and 3) my lesson plans for each class meeting are in Google Sites and linked.

This may not seem like a big deal until your servers go down and you have 48 students trying to access Moodle at once. For me, it meant the difference between postponing class and having each student finish the activities in the allotted time. I was able to send the students the links to the docs and lesson plan, and not one student missed a beat.

This does not mean LMS don't have their place. They are essential for posting grades and giving feedback to students. They are excellent for facilitating discussions within the class. They are also a great hub for content so that students only have to look in one place for course materials. In my experience, they don't even know I am linking to everything from a third-party host.

Other advantages to using third-party tools are:

1. When I want to update a document for multiple sections, I only have to make the changes in Google Docs and they automatically show up wherever the document is linked.
2. If I want to reuse materials for another class, I know where to find them. No searching archived courses to find rubrics, lesson plans or assignments. I just update the materials and link them to the current course.
3. I have access to my course materials if the servers go down, and I can easily send them to my students if necessary.

This has been quite the learning experience, and I am glad I came out of it on the positive side. What tricks and tips do you have for using LMS in your teaching?
