"Chrome already supports an offline mode. What?! It turns out that back in early 2013, Chrome networking engineer Randy Smith implemented support for an Offline Cache Mode (behind flags). With the feature enabled, if you're offline and navigate to a page with (stale) data in the cache, we'll show you the cached content."

"Nowadays it is hard to not see QR codes printed in advertisements, on products, and everywhere else. QR codes are one of the biggest trends in marketing right now, and you might wonder: can QR codes be of any use for academics? I say yes, and I urge you to use your own QR code everywhere it makes sense. That is, whenever there is an opportunity to supply an offline audience with additional online information including, but not limited to, your personal webpage, a research paper that accompanies your talk, or web resources that supplement your lecture. This post is about the basics of why, where and how to use QR codes in your research and teaching. In addition, it will also suggest a few design tweaks that allow you to blend QR codes with the surrounding context (e.g., the keynote slide or a poster). And if you invest some time you can even closely integrate a QR code with your overall self-branding efforts."

Andrew Miller, an educational consultant, writes that a "flipped" classroom still requires instructors to demonstrate the value of their content, whether online or offline. "Just because I record something, or use a recorded material, does not mean that my students will want to watch, nor see the relevance in watching it," he writes. " … If the flipped classroom is truly to become innovative, then it must be paired with transparent and/or embedded reason[s] to know the content."

The "flipped classroom" was being discussed in social lounges, in conference sessions, on the exhibit floor, on the hashtag and even at dinner. People wanted to know what it was, what it wasn't, how it's done and why it works. Others wanted to sing its praises and often included a vignette about how it works in their classroom and how it transformed learning for their students. Still others railed that the model is nothing transformative at all and that it still emphasizes sage-on-the-stage direct instruction rather than student-centered learning. I engaged in a few of these discussions offline and online, and while I'm still on the fence about my feelings toward the model, I can offer some insight and interpretation."
