The Big Picture
From the Earth Observatory News Room:
The Arctic Ocean’s shift from perennial to seasonal ice is preconditioning the sea ice cover there for more efficient melting and further ice reductions each summer. The shift to seasonal ice decreases the reflectivity of Earth’s surface and allows more solar energy to be absorbed in the ice-ocean system.

Setting the Dial on Rationality
Davis and Sumara’s book about complexity theory in education, mentions the Santa Fe Institute, a center for complexity research, but I’d never heard of it. They also referred to a book by M. Mitchell Waldrop, Complexity: The Emerging Science at the Edge of Order and Chaos, which as it turns out, tells the story [...]
Managing the InfoStream
Chris Lott’s post about managing the infostream comes at a time when I’m feeling overwhelmed with competing demands for my time and attention. There are hundreds of unread feeds in my reader, and a dozen open tabs on the web browser while I grade papers, plan lessons, meet with teachers, call parents, and work [...]
Putting Something Back
This coming week I begin teaching an after-school Web Tools for Teachers course. I’ve never done any professional development work, except on my own behalf, and I’m thinking about blogging and altruism today.
The idea of “sharing” is central to my understanding of blogging. I suppose that out of zillions of bloggers, others are [...]Going the Distance
One of my students was having trouble with some math exercises (as in, 480 cm. = __m) and I asked him to show me about how long a centimeter is, and how long a meter is, but that was hard for him because he didn’t have an intuitive sense of the relationship between meters and [...]
Tools for Teachers
On a positive note, some of the teachers I work with requested that I teach a 1 credit professional development course about web authoring tools. So the other night I wrote up a course proposal and presented it to the staff yesterday at the end of a meeting. I spent about 15 minutes explaining to [...]
In Practice
I’ve joined a group of teacher bloggers from Title 1 schools, writing about education policy and education technology. The blog is called In Practice. I’ve wanted for quite a long time (since I started blogging, in fact) to work on a group blog, so I’m very pleased to have this opportunity. Organizational guru, Alice Mercer, [...]
Fixing a Hole
I’ve had a class website at tellraven.us for about a year and a half. Before I set that up, numerous requests to the school district for server space got the same agreeable but non-responsive responses, so I did what anyone with a little knowledge and desire would do given the present state of the Internet. [...]
Redrawing the Shape of Learning
…the universe has come to be seen as “relentlessly nonlinear.”-Davis and Sumara
Will Richardson’s recent posts about the future of schools and teachers leaves me an opening for a new “big idea” that I’ve been working on lately. I finished reading Complexity and Education, by Davis and Sumara, which has me thinking about complex [...]
Metablognition: Bits & Pieces
I wrote a post last summer about blogging and identity construction with a similar title. This one is a little bit more about the blog in-use, it’s construction and maintenance. This post was prompted by some questions that Eric Hoefler asked. Eric is getting ready to change focus and hit the road, and he’s thinking [...]
