We're getting to a tricky place in Logic (categorical logic) during which time if students get behind, it's pretty tough to catch up since each new logical tool builds on previous knowledge. So, I'm working hard this week to provide extra, outside resources for students to use. I think of these as digital office hours (since very few people actually come to in-person office hours these days--maybe that's a different post!), though the difference is that students can view resources over and over again (and even at midnight, when I'm not having actual office hours).
Mostly, I'm creating and posting very short whiteboard lectures. There are a lot of whiteboard apps out there (for use with a touchscreen--I use my iPad). I've chosen a free app (Educreations) that is incredibly user-friendly, both for the creator and the viewer. The downside is that the lectures are stored on a website over which I have no control. I am able to keep the lectures private, but I don't technically have control over them. The stakes are pretty low, though--if I lose one, I can just take 5 minutes to create a new one. In fact, I was so lazy last night that I didn't bother looking for an old one--I just created a new one. I don't edit, so it really only takes me 5 minutes. If you're interested in whiteboard apps, come in for a chat in the teaching center. Here's an example of one of my lectures.
“An empirical philosophy is in any case a kind of intellectual disrobing. We cannot permanently divest ourselves of the intellectual habits we take on and wear when we assimilate the culture of our own time and place. But intelligent furthering of culture demands that we take some of them off, that we inspect them critically to see what they are made of and what wearing them does to us.” ― John Dewey, Experience and Nature
