I recently started using NearPod in my online classes. I like the features that allow students to self-assess, but it honestly works better in a live, teacher-paced setting. Nonetheless, I have used it to explain the differences between Web 1.0, Web 2.0, and Web 3.0.
I wrote a published article several years ago regarding Web 2.0 applications. Reading back over it now, I see how simplistic it was, and yet some of the ideas (and the apps) still hold true. The focus of the paper was in "making online learning relevant" in the wake of our putting entire graduate programs online. We looked for some features that could be added to the LMS we were using at that time (we have since moved from eCollege to Sakai and now to Canvas), and we even presented about it at a couple conferences, because it was considered "cutting edge" at that time.
Web 3.0 kind of threw me for a loop. I read SO MUCH about it without really learning much at all. It wasn't until I "ask(ed) Siri" for help that I found a truly useful article to which I want to credit and offer for anyone else struggling over the differences Web 3.0/The Semantic Web offers over its predecessors (actually its contemporaries since Web 1.0 and Web 2.0 aren't actually going anywhere).
