A Tantalizing Tabblo
Filed Under Graphics, Teaching 2.0, Tools, Web 2.0
Over the past three semesters, my education undergraduate students have been working with Panraven, a compelling and interesting web site that allows users to create, publish, and even print online storybooks. We have used Panraven to create sense-of-place projects with an eye toward using Panraven as a K-12 classroom tool. My students’ reactions to using Panraven–expressed personally and through their blogs–have been remarkably similar. While they love the final product–a nicely-formatted online storybook–they consistently struggle with Panraven’s many frustrating limitations and apparent beta bugs. Among those:
- Upload of images is frustratingly slow and often hangs in progress, requiring a browser restart and loss of work;
- Dragging images from the media folder to a project sometimes simply doesn’t work at all, again requiring a restart;
- Text boxes cannot be resized to accommodate more (or less) text than will fit in a given box;
- Images are fixed and cannot be moved around on a page to facilitate creative layouts;
- Viewing storybooks online seems inordinately slow, even on a fast campus-wide network.
For these reasons, most of my students reluctantly conclude that Panraven is not a reliable classroom tool, particularly for younger elementary students. The final product, while very compelling, is not worth the potential frustration of using the tool in a K-12 setting.
That’s why I was thrilled to be directed by a colleague to Tabblo (pronounce it “tableau”). Like Panraven, Tabblo creates online storybooks. (It also creates comic books and posters up to 24″ x 36″, but that’s another blog entry.) Unlike Panraven, however, uploading images is very fast. In fact, in my side by side tests on the same computer using the same network, Tabblo uploaded images many times faster than Panraven. Tabblo never hesitated to upload properly, and dragging photos into a story within Tabblo worked perfectly each time I tried it.
Viewing storybooks online is also much faster than with Panraven. Turning a page in Tabblo produces a pleasing”page curl” effect (which works forwards or backwards at both the top and bottom corners of a page) and there is no noticeable delay in loading the next page as there is with Panraven. On the other hand, Tabblo stories appear much smaller on a web page than do Panraven stories (which give you the option of enlarging the display if you want), making captions or small text difficult to read. If there is a way to enlarge Tabblo books, I have not found it yet.
Creating layouts in Tabblo is a breeze, and, while you can choose from a variety of preset layouts, the author is afforded complete control over the placement of images and text boxes on any page. Pictures can be moved from one place to another on a page or dragged off the page and stored in a virtual lightbox for use later. Text boxes can be any size and can be resized easily. It’s simple to insert new pages or delete unwanted pages. And–these actions happen quickly, with no discernible delay in execution.
Tabblo doesn’t win in every category, however. Panraven allows you to embed your stories into a blog, wiki, or other web page. I like this feature very much. Tabblo generates code that “simulates” embedding (that is, it places an image of the storybook cover in your blog), but that image is in reality just a link to the Tabblo web site. It would be wonderful if Tabblo allowed true embedding of projects into web pages.
Below is a test story that I created with Tabblo. Notice that the captions are difficult to read. I cannot find a way to increase the text size in the captions.
Even so, it looks like I am going to have to change my fall semester syllabus. We’re moving to Tabblo as an alternative to Panraven.

There are many times when the reality of a situation seems counterintuitive to an observer. A heavy skier reaches the bottom of a hill more quickly than a lighter skier, even though we think that objects should fall at the same rate or that a heavier object should push down harder on the ground and therefore move more slowly. (Google “terminal velocity” for the answer to that one.)
Similarly, we may intuitively feel that technology inhibits social skills of K-12 students, assuming that students must be interacting less with each other if they are using a computer. However, a pair of recent studies reviewed together in eSchoolNews suggests that, at least in a school setting, the use of technology can increase social skills among young students.
In “Tech Encourages Students’ Social Skills,” researchers X. Christine Wang and Cynthia Carter Ching explain the social upside of technology in a primary classroom setting. The first study, “Social Construction of Computer Experience in a First Grade Classroom: Social Processes and Mediating Artifacts,” examined the social interactions of a group of kindergarten and first grade students around two computers scheduled for their use during the classroom day. The newer, more capable computer was the students’ favorite, being everyone’s first choice for free time. Access to the computer was determined by a sign up sheet, and the rules were fairly simple. “Only two students could use a computer at one time, and a timer was used to limit each student’s time on the computer to only five minutes. Those students not being the first to select computers as their first choice activity had to sign up on a waiting list and do other activities while waiting for their turns.”
Wang and Ching observed that students tended to cluster at the computer and enforce the rules in ways that were fair to everyone. Achieving a common goal–in this case, reaching a higher level on a popular game–was a driving factor in the students’ ability to maintain order and also be successful at the game. The students were learning valuable social skills through having a common goal and a common interest in using the computer.
In the second study, “Digital Photography and Journals in a Kindergarten-First-Grade Classroom: Toward Meaningful Technology Integration in Early Childhood Education,” Wang and Ching observed kindergarten and first graders in the same classroom who were creating photo journals using Apple iPhoto software on an iMac. While students were to work with an adult helper while composing their journals, the researchers noted that other students typically played close to the iMac and interacted frequently with the journalists, often asking questions, supplying tips, or commenting on pictures or journal entries. They also interacted with each other while they were taking pictures of their classroom for their journals.
Wang and Ching feel that these studies provide evidence that students’ social skills can be improved through the thoughtful integration of technology tools.
“…the children are engaged in valuable social construction…of their classroom experience and culture by engaging with well-integrated technologies, such as computers or a digital camera.”
I realize that the scenarios presented by Wang and Ching are a far cry from the image we may hold of a high school student locked in his darkened bedroom late at night playing games and chatting–although these are also social activities of a sort and probably deserve some additional study as well. But studies like these help us realize that there is nothing intrinsically “unsocial” about technology. In some cases, technology can be a strong factor in successful socialization.

The Power of Embedding
Filed Under Blogging, Social Networking, Tools, Web 2.0
As an educator, I find myself posting content on a variety of online sources. In addition to semi-regular blogging, I manage several wikis, maintain a faculty home page, store and publish presentations on Google Docs, and I (somewhat reluctantly) use Blackboard for my ed tech classes. Many of those sources employ the same content. For example. a “How to Use Flickr Slidr” presentation might appear on my professional development blog for faculty, on Blackboard as a resource for my students, and as a URL on Google Docs. Reposting that document in numerous locations every time the original document needed to be modified would be time consuming and prone to mistakes. Besides, it violates my basic principle of doing work only once.
That’s why I find the idea of embedding media so powerful. Most online content services provide ways to embed media into a web page of just about any variety. All you need is a bit of site-generated code and authoring access to a web page. Blogs and wikis are great places to publish embedded media. Even stodgy old Blackboard will allow embedding and display of most media types. Imagine–you no longer have to upload a PowerPoint slide show to Blackboard and have your students download it for viewing. You can upload it Google Docs and embed it on Blackboard as a content item. Any changes you make to your slide show through Google Docs are immediately available to your students (it may require refreshing the Blackboard page) and it doesn’t take up any of your limited Blackboard storage space.
Embedding media is simply a matter of copy a few lines of code from a content service and pasting it into your blog, wiki, web page, Blackboard course site, or any other web page to which you have authoring privileges. The code is automatically generated by the content service site.
Here are a few of the content services that provide automatically generated code that can be copied and pasted into your sites:
- Flickr (photos)
- VoiceThread (voice and video annotated stories)
- Panraven (online storybooks)
- Google Docs (MS Office compatible word processing, presentation, and spreadsheet files; requires a Google account)
- Flickr Slidr (generates code for embedding Flick slide shows
- YouTube, and virtually every other video sharing site (videos)
There are some potential tradeoffs when using embedded media. For example, PowerPoint slide shows uploaded to Google Docs cannot have sound or animation. Careful authoring with these limitations in mind, however, usually results in useful and effective documents.
Below is an example of an embedded VoiceThread project, which I’ve chosen to present in a small size for faster access. Because I have allowed public comment on this project, video or voice annotations added to my original presentation on VoiceThread will automatically be reflected here, and vice versa.

An interesting follow up to my Feb 29 post (What Makes Finnish Kids So Smart?) showed up today from eSchool News. The article, U.S. Educators Seek Lessons from Scandinavia, reported on a visit to Scandinavian schools by the Consortium for School Networking (CoSN). The purpose of the visit was to find “answers for how students in that region of the world were able to score so high on a recent international test of math and science skills.”
CoSN’s observations speak volumes about the current state of US public schools. In Scandinavian schools, students begin formal education at 7 years, having spent the previous several years in preschool programs aimed at personal responsibility and social development rather than on academics. By the time they get to formal schooling, the situation looks like this:
[CoSN] found that educators in Finland, Sweden, and Denmark all cited autonomy, project-based learning, and nationwide broadband internet access as keys to their success… Grading doesn’t happen until the high-school level, because they believe grading takes the fun out of learning. They want to inspire continuous learning.
What the CoSN delegation didn’t find in those nations were competitive grading, standardized testing, and top-down accountability—all staples of the American education system.
The Scandinavians have apparently learned that drilling young children on facts and figures to produce better scores on standardized tests does not produce well-educated adults. Similarly, they seem to have figured out that guiding students into taking more responsibility for their own learning means that the students…ummm…learn more. And learning can be fun? Why is this surprising?
Could we design a system of public education that was any more backwards? If you need more evidence, visit the Orlando Sentinel.

Smithsonian Images Database
Filed Under Graphics, Teaching 2.0, Tools
Finding images for use in school settings is always an interesting exercise. Aside from the very obvious question of appropriateness of the image, there are questions of copyright, image resolution, and image authenticity. Google image searches and Flickr are wonderful tools, but there can be a significant amount of sifting through extraneous material to find just what you want, and the question of whether or not it’s legal to use that image can hinder the progress of a project.
That’s why resources such as Smithsonian Images are so useful for educators. Images are of very high quality, can be easily verified as authentic, and include a copyright license that allows for fair use for personal, school, or non-commercial use as long as proper credit is given when images are used. (Speaking of which, the image at left is a barite specimen photographed by Laurie Minor-Penland in 1995.)
As you might expect from the Smithsonian Institution, images are tracked by categories that are very useful to educators. The default categories are:
- Air and Space
- American History
- Animals
- Fireworks
- Gems and Minerals
- History of Technology
- Marine Life
- Military History
- Nature
- The Presidency
- Transportation
- Washington, DC
Other categories are available, and there is an excellent search engine on the site.

What Makes Finnish Kids So Smart?
Filed Under Culture
That’s not my title. It’s from this article in the Wall Street Journal. Read it right now. There is much food for thought here. Not mentioned in the article is the fact that Finland is the most wired country in the world with very high bandwidth Internet access available in every home. (If you thought Nokia was a Japanese company, you’re wrong. It’s Finnish.)

Podcasts are compelling tools for educators from two perspectives. For consumers of information, podcasts can provide portable, repeatable content that can be accessed at any time as often as needed. Study materials, how-to guides, lectures, guest speakers, and literature can be made available to students in a form that can be accessed through their computer or their iPod or other portable music player. For creators of information, podcasts help students focus on research, write for an audience, and use multimedia tools to publish original content. Many K-16 schools have embraced podcasts as teaching and learning tools. The Education Podcast Network showcases many examples of student-generated and subject-oriented podcasts along with details about creating your own podcasts. A quick Google search will uncover hundreds of additional sources.
Podcasts come in two “flavors.” Audio podcasts are typically MP3 files with vocal and/or music content, although there are other file formats available. (My favorite audio podcasts are the podcast versions of NPR’s Wait, Wait, Don’t Tell Me, a show that I dearly love but rarely hear live due to its broadcast time. All episodes live on my iPod and get played regularly.) “Enhanced” podcasts include images or video and may have addressable chapters available to the listener.
There are many tools available for educators to use to create their own podcasts. Mac users have the elegant GarageBand, which easily integrates voice, music, and video to create podcasts. (iLife ‘08, the current version, does an exemplary job of creating podcasts and is well worth the upgrade.) Other tools for Windows and Macs may be found here.
To fully appreciate podcasts, start by subscribing to a few of them. Apple’s iTunes Store is a great place to start. Select Podcasts from the store menu, select a category, and subscribe. (NPR’s content can be found under Featured providers.) Most are free. Seek out podcasts on topics that interest you, and start to imagine what kind of content you or your students could provide to others. You’ll be podcasting in no time…
