What Does Fluency Without Understanding Look Like?
Dan Meyer, dy/dan, 2018/09/07

"Conceptual understanding refers to an integrated and functional grasp of mathematical ideas" of of the ideas underlying a discipline in general. You could not be said to 'know' a discipline unless you have conceptual understanding. Yet, as discussed here (and here, and here) the idea that students should just learn formulae by rote appears over and over again. "There must be something deeply attractive about the idea that children’s math success can simply be forced upon them," writes Emma Gargroetzi.

Making E-Textbooks More Interactive
David Raths, Campus Technology, 2018/09/07

When I'm thinking of 'making textbooks more interactive' these days I'm either thinking o using them toconnect with a community, or to work with editable programs and live data, or both. But I think the idea of 'interactive' in this article takes us back to the days in the 1990s when 'interactive' meant 'you can push a button to play a video' or some such thing. Anyhow, all this 'interactivity' requires an Apple platform to operate. " iComp was created in Apple's iBooks Author, with tools such as Adobe's Premiere and After Effects used to enhance and edit video clips and Apple's Keynote used to create interactive widgets." :facepalm:

Building a body of knowledge work
Jim McGee, McGee's Musings, 2018/09/07

This is a bit of slice-of-life I guess, but I enjoyed the account of learning by doing (case studies). This is something I've discovered over time as well: "If I was to eventually create a case study that would work in the classroom or extend our understanding of this issue, I needed to get my thinking out of my head and available for inspection, by myself first and foremost." It aids in the whole process of pattern recognition that is crucil to knowledge creation. And of course there's a whole discipline devoted to this. "I did discover that this approach exists in its own rich context, as does any fundamentally useful technique. Anthropologist Clifford Geertz called it 'thick description,' Sociologists Barney Glaser and Anselm Strauss called it 'grounded theory.'" So there you go.

How to Live Stream on YouTube
Anthony Heddings, How-To Geek, 2018/09/07

It's funny to read that "YouTube’s live streaming support has gotten much better and is now a solid competitor to Twitch" but I guess it's true. I've been exploring the game-streaming world using YouTube with xSplit for the last few years. That's how I stream my talks. This article recommends an open source application called Open Broadcaster Software (OBS). Haven't used it; can't vouch for it, but the core idea here is that you use an application to capture the video feed and broadcast it to YouTube (or Twitch, or wherever) much the way a Digital Signal Porcessor (DSP) captures and sends audio signals for web radio. Twitch is probably blocked in your office (it is in mine) but this sort of technology has a bright future in e-learning.
