Peer Review vs. Search Engine Places - Quality of Information in a Web 2.0 Sources

Interesting article from EDUCAUSE Review, vol. 41, no. 6 (November/December 2006): 12–13 - Scholarly Reputations: Who's Got Buzz? that discusses whether:
scholars would choose (1) to have their work published in the premier journal in their field or (2) to have that work regularly come up on the first screen in an appropriate Google search

Having gone through a PhD process and having been in academia for 11 years where you needed to "publish" - this is a really interesting question to me. I often argued with (older) colleagues at the university that it would be better to have open, fast publishing sources than the very slow, peer review process associated with most publications. But what really caught my eye was the statement:
For information-seekers using their favorite search engine, quality is simple to define. If a result displayed on the first screen seems to be clearly objective in perspective, if it is not part of some commercial scheme (e.g., a link to buy this book at zzz.com), and if it is immediately available for full-file use, then it is deemed to be of high quality. Moreover, because the seeker has quickly been successful in obtaining a work of high quality, there is a transferal of quality to the work's authors, who receive a high "expert" ranking. The effect may not be rational but it is increasingly true, regardless of whether the work is otherwise associated with any peer-reviewed process. New graduate students in physics can be taught to begin research with review articles such as those in the highly respected Reviews of Modern Physics. Yet it is increasingly likely that they will first search Google; the article that shows up on the first page of results will be a winner no matter what its published pedigree.

My gut tells me that this is pretty accurate which argues that its possibly more important to be high up in Google search results than to be published in peer reviewed publications. Of course sometimes, both things happen such as in the case of Stephen Downes' article on eLearning 2.0 which comes up first in the Google search of eLearning 2.0. Of course this is a self-serving example, because looking at the list you'll see that I'm listed second and Stephen comes up again third. I'm grateful to be listed second but a few other scholarly articles on the subject are quite buried.

It's interesting that being ranked second and in-between two things by Stephen (who coined the term), definitely lends a mark of quality and high expert ranking for me on the topic. Is that right? Is it appropriate? Well as the authors point out, that's almost no longer the point - it simply is what it is.

But that's not always the case, even in a Web 2.0 world and even with the same term. Consider what happened around the definition of eLearning 2.0 on Wikipedia. I contributed the original definition using a combination of writing from Stephen, myself and a few other folks (mostly bloggers). I also included links to articles and posts that I thought were relevant - and who influenced the definition. About 3 months later, a Wikipedian came along and edited the article and selectively deleted links to some of the sources I had cited but not to others. Okay, I admit it, I'm a bit sore because links to my posts were deleted. The comment I received on how it was decided was that my posts were in a blog not in a peer-reviewed publication. I almost responded, "but there are other links to blog posts" but luckily realized that might mean deleting links to other "good sources" (in my opinion) and loss of all links to sources that are critical of the term. Don't worry though - I have an article coming out at some point and then I can add another link to something that has more credibility than my blog. :)

The point of this is that while the Educause article says:
In the Web 2.0 world, the quality of a resource is determined by the intensity of its use. What is rated as "the best" is what is used the most and what shows up first.

that's not quite right given that within some Web 2.0 domains there is still a form of review even if it shows up second. Ratings are often used. And all of this together is a form of review. What Web 2.0 does is distribute "review" more broadly and makes it much, much faster. The authors of the article clearly favor old-school peer review's quality filter. And, while I guess I'd agree that maybe not every vote should be equal, I don't necessarily agree that old-school peer-review is all that great. Maybe it's old scars in how peer review processes often work (political, old-boy network).

The real point is that even within a distributed, fast review model of Web 2.0, there are examples of old-school type review such as in the case of Wikipedia. And that felt even worse than the journal peer review process because the expectation is equal treatment.

Blogs, Automated Translations, and a Better Site Feed

I ran into a little utility this morning - Snap - that let's you add previews of any link on your site as a quick little pop-up. It's kinda cool. You'll have to visit my blog to see this in action.

While you are there, definitely check out the new translation capability that can be found at the bottom of each post. This is provided by Yahoo's, AltaVista's, BabelFish - aren't acquisitions fun? Since I've found that about 30% of the links to my posts come from blogs in other languages, maybe this will be of value. I've certainly been using it to translate from other languages to English so I can see what people are saying relative to the topics in my blog. I'm actually surprised at how much you can understand from automated translation. It makes me wonder if this isn't something that we should all be doing with our content whenever we have a multilingual workforce?

Of course, this then raised the question - can't I add this to my feeds? Well, I blew it a long time ago and didn't point everyone to my feedburner feed. Using FeedBurner, I can add lots of fun stuff to the feed and I've turned on publishing a daily summary of my del.icio.us links.

I would suggest that readers of this blog might want to change over to the FeedBurner feed to get these added functions: http://feeds.feedburner.com/eLearningTechnology

Web 3.0 - eLearning 3.0?

First let me apologize for talking about Web 3.0 and eLearning 3.0 when we don't really understand much less have digested eLearning 2.0, but there's so much buzz, I can't help myself.

Will Thalheimer posted about Web 3.0 and Learning where he is discussing what is being called Web 3.0. In particular he cites a recent NY Times article. But Web 3.0 has been getting lots of attention for a while now. The basic idea is to use the knowledge embedded within the web and include possible semantic web elements on top to begin to extract greater meaning so that we would be able to answer questions like:

"I'm looking for a warm place to vacation and I have a budget of $3,000. Oh, and I have an 11-year-old child."

Will (and I would agree) says that there will be big impact on learning if the web could answer these kinds of queries. However, Stephen Downes says:

OK, now, think about that. Do we ask questions like that? Well - no. First of all, we tend to forget to add the qualifiers (such as the budget and the child) when we ask. But even more importantly, we don't want to include some of this information in the question. It's an old rule - never tell the sales person what you're willing to spend. But also - I don't want to limit what I'm looking for. I'll spend more than $3000 if the trip is worth it, and I'll find a sitter for the child if I have to. What this means, then, is that whatever we're looking at, it won't be set up like a search or a query. It has to be much more subtle, much more interpretive, much more dynamic, much more immersive. The Web 3.0 people are talking about is the old Web 1.0 - we deliver content, you listen. But the next generation web will be more like Web 2.0 on steroids - the web itself will warp according my needs, my interests, my contributions.

I'm in the middle of grappling with similar questions for a particular client. They have very rich information with lots of meta-data and the question is not only what can we answer with the information, but what questions can we help to formulate. How much structure do we want to provide?

I think Stephen is onto something when he says that the web will warp itself to "my needs", "my interests" - but that's exactly the contextual stuff that he's saying that people often forget to add themselves. The web of the future will know that I'm not rich or poor (so $3000 is probably an okay number) and that I have an 11 year old. I shouldn't need to tell it again.

But there's also an aspect of the web providing suggestions that you wouldn't have thought to ask for ... and that's where I'm finding value today. Suggest potentially related results. Like more expensive vacations that are a little better. Or, if you'd only leave your child home you could go here.

I agree completely with Stephen that we are generally pretty bad about formulating questions. And I still believe this is a bigger stumbling block than formulating answers. See: finding answers and power of questions, better questions for learning professionals, and be an insanely great professional conference attendee. Because we aren't good at formulating questions, a big part of Web 3.0 has to be helping to:
find the right question to ask!

Web 2.0 Tool - Great Collaboration Example

Andrew McAfee has posted about Avenue A Razorfish's (AARF) Intranet that uses Web 2.0 tools as part of information sharing:

AARF has built interfaces to the bookmarking site del.icio.us, the photo sharing site Flickr, and Digg, a site where members vote on the importance of news stories. All three use tags, or something close.

AARF employees have learned to add the tag 'AARF' when they come across a web page (using del.icio.us), a photo (Flickr), or a news story (Digg) that they think will be of interest to their colleagues. Shortly after they add this tag, the bookmark (look at the top of the box), thumbnail of the photo (middle) or headline and description of the story (bottom) show up within the AARF E2.0 Intranet. So AARF has found a fast and low-overhead way to let its employees share Internet content with each other. It's also free; these interfaces with del.icio.us, Flickr, and Digg require no fees and no permissions. I find this simply brilliant.

This is similar to what I suggested in eLearning Technology: Personal and Group Learning Using Web 2.0 Tools and eLearning Technology: Social Bookmarking Tricks for Group Learning

Andrew has followed up on his original post with some concerns around security. Because the tags are visible globally, then other folks can see what is being tagged with AARF. This can be problematic. With some tools, e.g., Yahoo MyWeb, you can limit the visibility of your pages (or your tags) and I'd expect that to start happening with other tools as well. This is something I've discussed before: Yahoo MyWeb better than del.icio.us, rollyo, et.al. for Personal / Group Learning.

Both of Andrew's posts are definitely worth reading.

Great Example of Group Collaboration - e-Book: E-learning Concepts and Techniques

I found this via Eric Tremblay - e-Learning Acupuncture: Q: Does group collaboration online work?

E-Learning Concepts and Techniques is a collaborative e-book project by Bloomsburg University of Pennsylvania's Department of Instructional Technology students and guest authors. It was a project-based assignment for the online class, E-Learning Concepts and Techniques Spring 2006.

As an example - look at the section on Instructional Design Models. Quite well done. This is both a great reference piece and a great introduction to eLearning.

A link to the assignment.

Great stuff.

Guy Kawasaki - Art of Panels

Good post by Guy - The Art of Panels. He points to some other good resources:

I generally agree with everything presented with one exception - preparation and PowerPoint. Panels where the speakers just show up and answer questions often end up rambling and not nearly as effective as panels where speakers are prepared for introductory discussions and context setting. As a moderator I always have speakers prepare a few context setting slides and have them prepared for the topics we'll be covering.

At the same time, I agree with the suggestion that you don't want too much preparation. Instead the point is to drill into key issues and show parallels and contrasts in view among the panelists. So, from a more prepared context setting (often with PowerPoint slides to support) you go into a back-and-forth as discussed in the above pieces.

Clark Aldrich - "Second Life is not a teaching tool"

Clark Aldrich's recent post on LCB - The Learning Circuits Blog: Second Life is not a teaching tool - has me wondering what he thinks a "teaching tool" is?
Having said all of that, Second Life, as is, is not a teaching tool. It is content free. It is closer to a virtual classroom tool, or even a real-world meeting room or water cooler (without the actual water). Any content has to either bubble up from spontaneous conversations (great when they happen, but not predictable or scalable enough to provide an intellectual payoff), or be "brought in."

Ummm ... but aren't virtual classroom tools or meeting room tools a "teaching tool" if used correctly? And, if you are able to enhance these with persistent content, doesn't that become a teaching tool.

How about the ability to fly around the solar system? Could you maybe learn about the solar system that way? That's in there?

I think maybe Clark is more worried about distinquishing something from something:
mostly, I worry that educational simulations will be lumped together with Second Life

Not sure the point he's making. If someone scripts a simulation in Second Life, does that not count or something?

No matter what Clark says - Second Life is a teaching tool.

I personally believe that the next generation of Second Life that gets around some of the current technical issues and provides presence audio is going to have adoption patterns similar to virtual classroom / virtual meeting tools.
