David warns, we still tend to think of knowledge in the ways we did when books had to sit on a single place on the shelf, when knowledge had a single, possible, right form, rather than multiple forms.

This doesn’t mean there are no facts – but it does mean that people are going to insist on being wrong.”

David is actually quite concerned about difference, and just how much difference we can tolerate and still interact and function.

And one thing I’ve learned is that everything is interesting if looked at at the appropriate level of detail. Now, it used to be that you’d have to seek out places to plunge in over your head. But now, in the age of the Internets, all we have to do is stand still and the flood waters rise over our heads. We usually call this “information overload,” and we’re told to fear it. But I think that’s based on an old idea we need to get rid of. Here’s what I mean. So, you know Flickr, the photo sharing site? If you go there and search for photos tagged “vista,” you’ll get two million photos, more vistas than you could look at if you made it your full time job. If you go to Google and search for apple pie recipes, you’ll get over 1.3 million of them. Want to try them all out to find the best one. Not gonna happen. If you go to Google Images and search for “cute cats,” you’ll get over seven million photos of the most adorable kittens ever, as well as some ads and porn, of course, because Internet. So that’s two million vista photos. 1.3 million apple pie recipes. 7.6 million cute cat photos. We’re constantly warned about information overload, yet we never hear one word single word about the dangers of Vista Overload, Apple Pie Overload, or Cute Kitten overload. How have the media missed these overloads! It’s a scandal!

For example, in the old days if you watched the daily half hour broadcast news or spent twenty minutes with a newspaper, you had done your civic duty: you had kept up with The News. Now we can see before our eyes what an illusion that sense of mastery was. There’s too much happening on our diverse and too-interesting planet to master it, and we can see it all happening within our browsers

t Wikipedia, the articles are often relatively short, but they typically have dozens or even hundreds of links. So rather than trying to get everything about, say, Shakespeare into a couple of thousand words, Wikipedia lets you click on links to other articles about what it mention — to Stratford-on-Avon, or iambic pentameter, or about the history of women in the theater.

Teachers before students. When you roll out tech, ensure you give teachers an opportunity to learn about and use the tech, before you provide it to the students.  Don't require. Inspire. Do not require all teachers to accept and use the technology. Start with the teachers who are most excited. Ask teachers to write short and sensible proposals about how they want to use the tech. Empower those teachers to help guide others along.  If you deploy to grade levels, start with the older students. If you start with lower grades the upper grades will resent that they never had the opportunity to have access to the tech. If you start with the upper grades, the lower grades will be excited about what they have to look forward to. 

Follow him at @Mr_Casal to get great ideas about how social media can be used to build and strengthen the school community. For those concerned about getting administrators on board, he shared information on how to explain how social media meets the standards

Learners construct new knowledge, upon their own existing knowledge.  This is very individualised, and based on each learner’s past experiences, and ways of thinking.

Learning designers have some tricks to help deal with such diversity, such as researching your cohort, conducting a needs analysis, and ultimately categorising learners and focusing on the majority.

In brief, the evolved form illustrates three kinds of aggregation of learners in either formal or informal learning: groups, networks, and sets. We originally conflated sets with a further emergent entity that is not a social form as such, which we have referred to as the collective

the tutor can respond directly to questions, adapt teaching to the learner’s stated or implied reactions, and the learner can choose whether to intervene in the course of his or her own tuition without contest with others (Dron, 2007

one-to-one dialogue represents an “ideal” form of guided learning, at least where there is a teacher who knows more than the learner and is able to apply methods and techniques to help that learner to learn
