Textcast turns any text — documents, web pages and entire blog feeds — into personal podcasts you can listen to right on your iPod and iPhone.

If kids can get the lectures, can get the content delivery and skill modeling as well (or often better) by computer lecture than in person, why do we have use precious class-time for this purpose?  Why do we, in the status quo,  replicate in person in our classrooms what is easily available elsewhere, the content delivery/skill modeling, and then have kids apply their learning to difficult problems at home, without us there to help? Increasingly,  education’s value-add is and will be in the coaching and troubleshooting when students are applying their learning, and in challenging students to apply their thinking to hands-on learning by doing and teaming:  so let’s have them do these things in class, not sit and listen.   We know that collaboration is a critical skill set which can’t be developed easily either on-line or at home alone– let’s have students learn it with us in our classrooms.   Let every classroom be a collaborative problem solving laboratory or studio.

I suppose earlier generations had to sit through all this huffing and puffing with the invention of television, the phone, cinema, radio, the car, the bicycle, printing, the wheel and so on, but you would think we would learn the way these things work, which is this: 1) everything that’s already in the world when you’re born is just normal; 2) anything that gets invented between then and before you turn thirty is incredibly exciting and creative and with any luck you can make a career out of it; 3) anything that gets invented after you’re thirty is against the natural order of things and the beginning of the end of civilisation as we know it until it’s been around for about ten years when it gradually turns out to be alright really.

In other words the cost of connection is rapidly approaching zero, and for a very simple reason: the value of the web increases with every single additional person who joins it. It’s in everybody’s interest for costs to keep dropping closer and closer to nothing until every last person on the planet is connected.

Another problem with the net is that it’s still ‘technology’, and ‘technology’, as the computer scientist Bran Ferren memorably defined it, is ‘stuff that doesn’t work yet.’ We no longer think of chairs as technology, we just think of them as chairs. But there was a time when we hadn’t worked out how many legs chairs should have, how tall they should be, and they would often ‘crash’ when we tried to use them. Before long, computers will be as trivial and plentiful as chairs (and a couple of decades or so after that, as sheets of paper or grains of sand) and we will cease to be aware of the things. In fact I’m sure we will look back on this last decade and wonder how we could ever have mistaken what we were doing with them for ‘productivity.’

Q: What are some of the ways that you've applied ideas and research about attention and learning in your own classroom? A: I rarely lecture anymore. I structure my classes now with each unit led by two students, who are responsible for researching and assigning texts and writing assignments and who then are charged with grading those assignments. The next week, two other students become our peer leaders. Students learn the fine art of giving and receiving feedback and learning from one another. I structure midterms as collaborative “innovation challenges,” an incredibly difficult exercise which is also the best way of intellectually reviewing the course material I’ve ever come up with. In other words, more and more I insist on students’ taking responsibility for their learning and communicating their ideas to the general public using social media.

If you want to learn more, you can find syllabuses and blogs on both the HASTAC and the DMLCentral site. I posted about “This Is Your Brain on the Internet” and “Twenty-First Century Literacies.” I also led a forum on interactive pedagogy in large lecture classes.
