Here is the site of the project: http://www.scuola-digitale.it/classi2.0/
In my opinion it should be based on four pillars.
1. It should go beyond the sterile contrapposition between theory and practice for a generative learning context
2. Knowledge is to be constructed and not transmitted
3. Technology in the classroom should become gradually invisible
4. The idea of a class 2.0 is a lab as it was for Freinet and a learning community (Jonassen).

Adobe offers a free, scaled down version of its photo-editing software.
Today, when you take pictures with your digital camera, you have an inordinate number of options for online editing, storing, and sharing your shots. Thanks to improvements in Flash, popular graphics software, and the availability of fast broadband connections, a number of impressive online photo-editing sites have emerged in the past couple of years. Now Adobe is jumping into the fray with its new online photo-editing software called Photoshop Express. The service opened a test version to the public, which offers simple editing tools, syncs with Facebook, Picassa, and Photobucket, and provides two gigabytes of free storage. Photoshop Express requires Flash Player 9 to run and works with all major browsers, including Firefox, Internet Explorer, and Safari. A user first uploads pictures from a hard drive to Adobe’s servers, a process that takes a couple of minutes, depending on the speed of the Internet connection and the size and number of photos. Once uploaded, the photos can be edited with a simplistic editing toolbar that lets the user crop, adjust exposure, touch up blemishes, remove red eye, and change the color saturation. As well as these basics, Photoshop Express lets users fine-tune the color and lighting with controls such as white balance and a tool that sharpens blurry edges. In addition, a user can add more creative elements to a picture with a sketch tool and a distort feature. In terms of editing, Adobe’s offer isn’t impressive. It lacks editing tools available in other online editors, including Picnik (used by the photo-sharing site Flickr), FotoFlexer, and Rsizr. Rsizr, for instance, offers an innovative tool that can compress and expand images without distorting them. Moreover, this initial version of Photoshop Express comes up short in terms of storage. Sites like Flickr and Photobucket offer unlimited storage, albeit for a price. (Express shouldn’t be compared with Adobe Photoshop C3, the professional editing suite that can cost nearly $1,000, or Photoshop Elements, desktop editing software for under $100, because it’s free and vying for a different audience.) These are just the early days for Photoshop Express, notes Geoff Baum, director of express solutions at Adobe, who pitched the idea of Web-based products about two years ago. “It’s not quite there yet,” he says. In the coming months, the company will offer more features, depending on user feedback, as well as more storage and the ability to synchronize photo libraries with additional websites. One particular feature that will be available soon, he notes, will be access to a printing service. |
As it is, Express has a number of appealing characteristics. The interface is easy to use and intuitive. It’s exceedingly simple to update photo libraries and edit pre-existing photos on sites such as Facebook. The service includes thumbnails that give the user an instant glimpse at how a specific editing decision will change the picture. And importantly, it’s easy to see the changes you’ve made to the picture and retract any of them individually using the toolbar on the side of the screen. For instance, if you’ve cropped and rotated a picture, changed the white balance, and converted it to black and white, a check mark appears next to these editing options in the toolbar. To retract an edit, simply click the check mark.
One drawback to Express is that it’s impossible to edit pictures while waiting for others to upload to Adobe’s server. Baum says that future versions might address this problem, especially if they incorporate Air, Adobe’s forthcoming software that allows online applications to run without an Internet connection. “We’re planning on taking certain components of Photoshop Express and putting them on Air so you can use them in a connected or unconnected environment,” he says. For instance, in the future, you might be able to edit pictures offline, and Air would automatically update your photo library when you connect to the Internet.
Baum says that Adobe has a few plans on how to make money from Express, even though the company is giving it away for free. For instance, while the two gigabytes of storage will remain free, Adobe will likely charge for certain advanced editing tools and more storage. Additionally, the company could license Air-enabled desktop components for Photoshop Express to computer manufacturers when they include the software on new machines. But another part of the plan, says Baum, is to give a younger generation a glimpse at Adobe’s capabilities and hopefully interest them in more advanced (and expensive) Adobe products. “It’s about connecting with an audience we hadn’t had a lot of sway with,” he says.
The difference between good and bad traditional textbooks lies mainly on their layout, their contents and the way they are delivered. These three categories are not sufficient to spot the differences between high quality and low quality e-textbooks.
Lots of other elements are to be considered as for example a clear shift in methodology which activates the student’s cognive process and forsters interaction beyond the plain paper to access the wide web pages.
Garamond has paved the way to re-thinking teaching and learning by using e-books.
It is a professional development project and virtual extension of the TESOL 2008 Convention in New York. The intended audience for this project includes both TESOL 2008 participants and those who can participate only virtually.You do not need to be a TESOL member to participate in a free , six-week , wholly online session of the EVO, Jan 14 - Feb 24, 2008.

I’ll talk about them later in this blog!
If your educational materials are not “social objects” - in other words, if you don’t already understand that their main purpose is to bring people together so that social learning interactions can happen - why are you producing and sharing them? A relevant follow-up question is, if you are not providing the functional space for these social learning interactions to happen in (or at least pointing to a space where they can), why are you producing and sharing them? This is the key question for all OER and OCW projects.
Google recently announced Knol, a new experimental website that puts information online in a way that encourages authorial attribution. Unlike articles for the popular online encyclopedia Wikipedia, which anyone is free to revise, Knol articles will have individual authors, whose pictures and credentials will be prominently displayed alongside their work. Currently, participation in the project is by invitation only, but Google will eventually open up Knol to the public. At that point, a given topic may end up with multiple articles by different authors. Readers will be able to rate the articles, and the better an article’s rating, the higher it will rank in Google’s search results.
Google coined the term “knol” to denote a unit of knowledge but also uses it to refer to an authoritative Web-based article on a particular subject. At present, Google will not describe the project in detail, but Udi Manber, one of the company’s vice presidents of engineering, provided a cursory sketch on the company’s blog site. “A knol on a particular topic is meant to be the first thing someone who searches for this topic for the first time will want to read,” Manber writes. And in a departure from Wikipedia’s model of community authorship, he adds that “the key idea behind the Knol project is to highlight authors.”
Noah Kagan, founder of the premier conference about online communities, Community Next, sees an increase in authorial attribution as a change for the better. He notes the success of the review site Yelp, which has risen to popularity in the relatively short span of three years. “Yelp’s success is based on people getting attribution for the reviews that they are posting,” Kagan says. “Because users have their reputation on the line, they are more likely to leave legitimate answers.” Knol also has features intended to establish an article’s credibility, such as references to its sources and a listing of the title, job history, and institutional affiliation of the author. Knol may thus attract experts who are turned off by group editing and prefer the style of attribution common in journalistic and academic publications.
Manber writes that “for many topics, there will likely be competing knols on the same subject. Competition of ideas is a good thing.” But Mark Pellegrini, administrator and featured-article director at Wikipedia and a member of its press committee, sees two problems with this plan. “I think what will happen is that you’ll end up with five or ten articles,” he says, “none of which is as comprehensive as if the people who wrote them had worked together on a single article.” These articles may be redundant or even contradictory, he says. Knol authors may also have less incentive to link keywords to competitors’ articles, creating “walled gardens.” Pellegrini describes the effect thus: “Knol authors will tend to link from their articles to other articles they’ve written, but not to articles written by others.”
Google also faces the difficult task of generating a useful body of knowledge from scratch. According to Wikipedia, it has taken more than seven years to generate its 9.25 million articles. “There’s really no shortcut to getting this kind of coverage,” says Pellegrini.
But Google is well positioned to provide a monetary incentive for content generation through its advertising programs, such as AdSense. If Knol attracts the number of users Wikipedia currently enjoys, Google has an opportunity to publish an equivalent number of ads. And some of that revenue would find its way to content providers. Manber writes, “If an author [of a Knol article] chooses to include ads, Google will provide the author with substantial revenue share from the proceeds of those ads.”
These payments are likely to be modest, however, especially when the site is newly launched and doesn’t yet have enough content to attract many readers. And Kagan believes that for many online content contributors, small payments from revenue-sharing programs will prove less of an incentive than the desire to share something they are passionate about. He points to the example of the revenue-sharing video website Revver, which has yet to approach the popularity of YouTube. “Many times, paying users to do things they wouldn’t genuinely do proves not to work,” Kagan says.
Google is betting that, if it can generate enough content, its expertise in search–and the effectiveness of peer review–will give it a competitive advantage. But while reader rating systems are common on sites that review goods and services, such as epinions and Amazon.com, it’s unclear how effective they will be as a means of promoting user-generated content. Manber writes, “Google will not serve as an editor in any way, and will not bless any content.” Wikipedia and peer-reviewed journals, by contrast, have mechanisms for preventing the proliferation of inaccurate content. Peer-reviewed journals publish only those articles deemed worthy by a group of the author’s academic contemporaries. Wikipedia articles are constantly edited by numerous authors, so bogus information is typically removed quickly. In 2005, Nature found that there was not a substantial difference between the accuracy of scientific articles on Wikipedia and those in the Encyclopedia Britannica.
