If I had a desert island EdTech, it would be blogging, and that is not just in a nostalgic sense. No other educational technology has continued to develop, as the proliferation of WordPress sites attests, and also remain so full of potential. I’ve waxed lyrical about academic blogging many times before, but for almost every ed tech that comes along, I find myself thinking that a blog version would be better: e-portfolios, VLEs, MOOCs, OERs, social networks. Sometimes it’s like Jim Groom and Alan Levine have taken over my brain, and I don’t even mind. I still harbour dreams of making students effective bloggers will be a prime aspect of graduateness. Nothing develops and anchors your online identity quite like a blog.

Blogging is durable, open, and democratic indie ed-tech.

As Ryan indicates, the planet-like features that OPML subscriptions provide are immensely valuable in general, but also solves a tough problem that some of the best minds in the educational tech space have found perennially problematic.

I want to stress the indie ed-tech perspective. Mainstream ed-tech is very much about behaviorism and surveillance. We need an indie ed-tech that can bring safety to the serendipity without monetizing kids.

Communication is oxygen. Build a districtwide collaboration infrastructure and an open by default culture.
Mindset Marketing, Behaviorism, and Deficit Ideology
Default to Open: Open Education, Open Government, Open Data, Open Web, and Open Source
Hyperlinks and Education in the Disinformation Age
Feed Readers, Micro.blog, and Digital Pedagogy
Bring the backchannel forward. Written communication is the great social equalizer.

@rboren I agree with @chrisaldrich and @audreywatters in fact believe #IndieWeb a moral imperative for a schools https://t.co/J4tTR7Ihqp (https://t.co/HDEjoGRUpV)

We also believe the path to becoming a better reader relies on becoming a writer. Children excel in production based literacy environments. The critical evaluation of online sources is no different. Any classroom exercise around sourcing must involve readers reflecting on their process and interacting in social spaces for reading. We believe the best way to do have students understand how the web shapes meaning is to use the web to make meaning. Part of any intervention should embrace students publishing on their own domain with parents and students in control of their privacy.
We also believe teachers should be central in educational research. Part of any intervention must encourage educators to build, share and remix resources while reflecting on their learning in the open. We can not tackle critical evaluation alone. Furthermore we must recognize that our teaching corps requires a basic understanding of how you read and write on the web and the lack of skills in our teachers is a national crisis. Students will never be ready for computer science classes in middle school and high school if they are taught by educators who can’t add a link in an email let alone build a web page. By encouraging teachers to network through the use of OER sharing we can address the lack of skills.
