Tackling Copyright Issues with Flickr Storm

August 17, 2008 · Posted in citizenship, graphics, Tools · 6 Comments 

In my classroom, we deal with digital images on a daily basis. They end up in our digital videos, PowerPoint stacks, blogs, and posters. My “Teaching with Technology” students are required to have Flickr accounts to organize and share their photos, and we spend a lot of time learning how to resize and repurpose images for different media.

A couple of well-chosen search terms entered to Google will return a plethora of images on any imaginable topic. And therein lies the problem; it’s so easy to find the images that we want that we tend to forget that every image published on the web is copyrighted. In order to legally use that image outside of the classroom, we must have permission of the copyright owner.

As a teacher of teachers, I feel doubly responsible about modeling the right behavior for my post-secondary students. I need to make sure that my teacher candidates know the copyright ropes so that they can properly instruct their students when they become teachers. That’s why I love Flickr Storm.

Flickr Storm is a web-based service that allows you to search Flickr for photos by license. The key is to use the Advanced menu for all of your searching.

When you click the Advanced menu link, you are presented with a drop-down menu with a choice of license types. The majority of photos posted to Flickr are licensed under the “Attribution” agreement, meaning that you can use the photo in a commercial or non-commercial project as long as you give credit to the copyright owner.

There are many other nice features of Flickr Storm. The attribution URL is clearly shown so that you can copy/paste the attribution information into your project. You can create an online library (a “tray” in Storm lingo) of found images on a topic with a URL that you can share with others if you want.

Using Flickr Storm for searches helps me call attention to copyright issues with my students, provides them with a rich source of usable images for their projects, and gives credit to the copyright owners for their work. It’s an essential element of working with digital images.

A Tantalizing Tabblo

May 6, 2008 · Posted in graphics, Teaching 2.0, Tools, Web 2.0 · Comment 

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.

The Power of Embedding

March 27, 2008 · Posted in Blogging, social networking, Tools, Web 2.0 · 2 Comments 

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.

Smithsonian Images Database

March 3, 2008 · Posted in graphics, Teaching 2.0, Tools · 1 Comment 

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.

barite crystalThat’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.

Podcasting in Education

February 26, 2008 · Posted in Tools, Video · Comment 

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.

iTunes PodcastsTo 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…

Macintosh Graphics Software

January 12, 2008 · Posted in graphics, Tools · Comment 

Macintosh computers ship with an astonishing array of incredibly useful media software. The iLife suite (iMovie, iPhoto, iDVD, iTunes and iWeb, GarageBand) provides wonderful tools for creating and publishing media files across a variety of platforms. (Why a musician would buy any computer that did not ship with GarageBand is beyond me.) Intel-based laptops have been shipping with the incomparable Comic Life for quite some time. Even the viewer application Preview has excellent tools for cropping, resizing and adjusting photo a range of color parameters for photos.

It strikes me a strange, then, that Macintosh–the platform that included the wonderful MacPaint and MacDraw applications from its first incarnation–does not ship with simple drawing and painting software. This omission is particularly problematic in K-12 education. Kids love to draw, and their illustrations often form essential elements in their stories. Schools with limited budgets must often overlook drawing and painting applications in order to acquire word processing and spreadsheet software. What’s a third grader to do?

Fortunately, there are some solutions that fill the gap nicely. In this post, I’m going to concentrate on freeware applications that are usable by even elementary students. (I’m saving higher-end programs such as GIMP–a full-featured PhotoShop alternative–that are too complex for younger students for a future post.)

Seashore
Picture 1Seashore is a free painting program with a surprisingly strong array of tools. All the expected tools are there–paint brush (with lots of options), eraser, pencil, fill bucket, magic wand (for selecting colors) and marquee tools for selecting areas of your painting. There’s also a smudge tool for blending colors and a PhotoShop-like clone (rubber stamp) tool. You can control the transparency of your paintings and even paint with a large variety of included textures. For more advanced artists, you can add layers and manage red, green, and blue color channels.

Tools are easy to select and understand even for younger students. It’s a fine all-around painting program that should be on every K-12 Mac.

Image Tricks
seashoreIf your graphics needs run more toward the photo processing side, consider Image Tricks from BeLight Software. Image Tricks uses the Mac’s built-in Quartz imaging tools to create an easy and fun to use photo editing environment. You can open or paste in photos or scanned images from any source (a handy link to iPhoto is available) and alter them to your heart’s content. Apply filters, change colors, rotate and distort images, crop and resize photos, and save in jpg, png, tif, gif, and even pdf formats. The Masks feature lets you apply borders and frames to your images. All filters can be easily tweaked to create beautiful and unusual effects. The tools are easily accessible and encourage experimentation and exploration.

Mac users already have powerful photo editing tools in iPhoto and Preview. But Image Tricks has some new and exciting capabilities that expand the possibilities for working with photos. And–it’s tons of fun.

Listen to Any Good Books Lately?

October 29, 2007 · Posted in audio, Tools · 1 Comment 

Today’s post points to a variety of free online audio resources. These resources can provide valuable primary and supplemental tools for teaching and review as well as links to research materials for students.

LibriVox
LibriVox is the mother-of-all free audiobook resources on the ‘Net. Nearly 1000 titles are available, all searchable by title, author, category, and genre. Most of the classics are here as well as many modern and contemporary essays. Files are available in mp3 or ogg vorbis formats. Where available, links are provided to text versions (e.g., from Project Gutenberg) of the material. All recorded books are in the public domain in the US, and all are read by human readers. There is an RSS feed available to alert you when new materials are added, and you can even volunteer to be a reader.

Project Gutenberg Audio Books
Known mostly for its vast array of public domain print books, Project Gutenberg also offers many of its titles as audiobooks. Entries are read by human readers (or by synthesized voices; see below) and are available in many different audio formats, including mp3, m4b (iTunes/iPod), and ogg vorbis. Project Gutenberg no longer adds synthesized books to its library, preferring instead to use human readers, but they are migrating to an “on demand” service for delivering synthesized text to visually-impaired individuals. My favorite feature of PG is the full-text search capabilities, allowing the reader to search for occurrences of words or phrases within the texts themselves. Of course, PG also supports searching by author, title, etc.

Free Classic Audiobooks
This site offers a limited range of titles (around 60), but the offerings are compelling–from Huckleberry Finn to Alice in Wonderland to Shakespeare’s Sonnets to Notes from the Underground to the 911 Commission Report. Roughly half are read by humans; the remaining titles using an “advanced” synthesized speech that is quite understandable. All titles are available in mp3 format and in m4b format for iPod or iTunes. Books are segmented into chapters for easier downloading or downloading of specific chapters (great for review purposes). I love throwing these on my iPod for long car rides. They also make great review items for high school British and American literature classes.

LearnOutLoud.com
This web site is a portal to thousands of online books, lectures, podcasts, and videos on a wide variety of topics. Some are for purchase, but LearnOutLoud offers a directory of hundreds of free audio and video resources arranged by topic, including Arts, Literature, Science, and Language. (Scroll down the page to find the free directory.) Items in a topic can be sorted in several ways, including alphabetically, by author, or by title popularity.
