I apologize if I begin to sound like a crotchety old man in these posts, but I am having trouble getting very much of this information through my overly cynical mental filters.
Warlick
First off, I appreciate David Warlick's dedication to improving education through the integration of technology over the last three decades; it is to be commended. That said, even though he is only giving an informal synopsis of his longer talk, I cannot imagine increasing the length would make it anymore comprehensible. The talk seems to be a bag of poorly conceived ideas, unconstrained by the strictures of reality, thrown together in a haphazard fashion. I bet that he actually has some interesting things to say about the subject, but like so many popular educational thinkers nowadays, he frequently overstates his points and tries to wax philosophical without the required logical arguments. Let's look at his main points.
He believes there are three converging conditions that are going to have to change the way we view education.
1.) "
We are preparing kids for a future we cannot clearly describe. This is the first time in history where we are facing a situation where we do not know our children's future. We do not know the future we are preparing them for."
I sure hope that David is (was) not a history teacher (he wasn't). If he was, he would realize that we have never known or could predict the future (technologically, economically, socially, nationally, or otherwise) with any good degree of accuracy. Here is a
PBS Technology Timeline. What events in this timeline were predicted twenty years before hand, with accuracy? Why is today any different? We prepare students for the every changing present and the immediate future, adjusting instruction along the way if needed.
One of the problems with these talks is that no one seems to understand how to structure an argument or present a proposition with nuance. If he were to say, "The future is more uncertain today than it ever was in the past because of (insert premises from which the proposition can be inferred) " then maybe I could agree with his point. But the world has been progressing pretty darn quickly since the Enlightenment, and the pace of progress is surely accelerating as complexity tends to build on itself (plus, as the population grows larger, there are so many more lives being lived in a given amount of time). But, again, there has always been uncertainty and I can think of no reason why this next generation is going to experience change drastically different than the few generations preceding it.
2.)
"Our kids are different...They spend a lot of time online, their playing video games, their engaging with online communities. And they have come to understand information differently than my generation. "
I don't believe students have fundamentally changed in one generation. Yes, they are online more than we were at their age, but does this imply they are fundamentally different and need to be instructed differently? I don't buy it. My dad's generation watched a lot more TV than his parents' generation, and they in turn listened to more radio than their parents. Either way, every generation still gets their information from reading, listening, watching, and doing. I have not yet heard of students having infrared binary information beamed directly onto their retina.
Students certainly have more access to information than previous generations could have ever dreamed of, but the saturation point was exceeded long ago, before the Library of Alexandria burnt to the ground. That is, we have had way too much information for any one person to process for thousands of years, and piling on more information does not profoundly change this dilemma facing us as individuals.
He speaks as if this new generation experiences the world in some strange, wonderful, or magical way. I could almost guarantee they process the world the same way we do, but without the memories of how difficult it used to be (in hindsight) to access the vast information our species has acquired. Information is still a product, but an increasingly free product. And it is still manipulated in pretty much the same way it always was. What does he think students are doing with this information that is so unique? Talking about it? Writing about it? Sharing their ideas? Combining different insights? Generalizing?
[added by edit] I think I was wrong to say that students are manipulating information in same way as previous generations. While I still think this is true with regard to the
content conveyed by the information, i.e., they are still just reading it, critically analyzing it, discussing it, etc. albeit more extensively and easily, what is innovative is how they can
organize this information into personalized taxonomies. These taxonomies can then evolve in tandem with others'.
This will not only provide an external framework for storing, retrieving, and sharing information, but can also provide a new and interesting internal framework for the same purpose. This is essentially what it means to understand something, i.e., integrate it into an internal hierarchical framework to add context and establish connections with other information. Whether the distinction between
content conveyed and its
organization can be justified, I am not sure. If not, then it may be perfectly legitimate to say that they are actually changing knowledge by adding descriptors, tags, hierarchies, etc.
Is this a good thing? I am not sure, as there are already well established frameworks ("tags,") for retrieving this information that was developed by experts while the content itself was being developed. For instance, if someone tags a Lubber Grasshopper as a "bug," it will true in the colloquial sense, but not in the entomological sense. Maybe it would be better for experts to organize their information, and for amateurs to learn how to navigate their frameworks; as I mentioned earlier, these frameworks are probably continuous with the content, so having an improper framework is deleterious to comprehension.

3.) "The information. We have this thing called Web.2.0...the very shape of information is changing. The information is more of a conversation...Now we are increasingly going to the community to get the answer."
From what I can understand with regard to this segment, David is saying that people are collaborating more in order to find out the answers to questions that no authorities can help with. I can't disagree with that, but information is not changing into an open conversation for all fields. Yes, at the cutting edge of knowledge, where David thinks he is, the internet allows more collaboration at faster rates and the information gets modified more quickly. But for most of what students are learning, the knowledge is still the product of thousands of individuals over thousands of years; it is not new and developing.
The video starts getting really strange at this point. He tries to define a new definition of literacy in the age of information, but simply states goals that have always been important in education. He states the new literacy is defined by the ability to:
1.) Expose the truth: i.e., critically evaluating information, which dates back, formally, to at least the Greeks.
2.) Process and employ information: how is this only applicable in our new world of easily accessible information?
3.) Express ideas compellingly: Ibid.
4.) Use information ethically: Ibid.
Weinberger
The David Weinberger podcast was a little more restrained and I really couldn't disagree with much except their armchair philosophical claims that the nature of knowledge is radically changing.
The hyperlinking phenomena is great, and does show explicitly the limits of trying to demarcate knowledge. But still, we do need to demarcate it for any practical purpose. I think one of the best uses of this new accessibility to information (hyperlinking, videos, forums, etc.) is the interactive, multimedia e-book. Some things are best shown in video format and/or through the use of an application, and e-books can integrate this seamlessly into a text. For instance, Carl Zimmer's evolution textbook
Evolution: Making Sense of Life and Richard Dawkins
The Magic of Reality both employ various multimedia and hyperlinks to convey their information. Once this art is perfected, I predict it will make learning the material that much easier for the students.
David and Alan also discuss the fact that the act of learning is becoming more public as students participate more in online blogs, forums, and chatrooms. I would have to agree that this is something new and interesting. Learning should become easier if students can get most questions answered immediately by referencing previous online discussions about the same query. It will be a great resource, but I think its just going to expand upon classical methods of learning, not fundamentally change the game. (Or "change the nature of knowledge as we know it") Who knows though?
