I am not a fan of chalkboards. Chalk is messy and always ends up somewhere on my clothes by the end of class. I also regularly encounter chalkboards that don’t erase well and become unreadable as more and more dust gets smeared across the slate. When I was in grad school, Andy Myers solved this problem by having his teaching assistants clean the board with water and squeegees *during* class. While I am not afforded the benefit of a squeegee team at SLU, I suppose we could hire some adjuncts.
Though I am not a fan of chalkboards, I am a big proponent of drawing structures and working problems during class. In the fall, there were a couple of times I resorted to using transparency film and colored pens. It worked, but it was clunky. In an effort to step up my game, over winter break, I went on eBay and shelled out some cash so that I could ditch the transparencies and use my iPad instead. My tool kit now includes:
1 tablet stylus
1 Apple lightning-to-VGA adapter
1 VGA switch box
2 VGA cables, 6′ long
1 handsome bag for transporting everything in style
Prior to class, it usually takes me three or four minutes to turn on the projector, load my PowerPoint slide deck on the room computer, and plug my iPad into the projection system. This involves connecting the iPad to the projector through the lightning-to-VGA adapter and a VGA cable. If the room only has one input servicing the projector, you’ll need to use the VGA switch and a second VGA cable so you can toggle between your slides and the tablet.
Writing with the device is pretty simple. I use the app called Notability, which costs $4.99 and is worth every penny. Before class, I’ll upload PDF files of any quizzes or exams I want to review that day onto Google Drive, then download them into Notability on the tablet. Once you’ve done this, you can write/draw on top of the document and screencast everything through the projector. Here’s a screenshot of a typical session:
I love the number of colors to choose from and the fact that you can save the marked PDF and post it for the benefit of the class. I’m still getting the hang of drawing structures as crisply as I would like, and I think part of the problem is the thickness of my stylus. I’m also considering buying a tablet with a wider screen, because things can get kind of cramped on the iPad.
While the overall system was recognized as an improvement by the students in their course evaluations, I should mention one little slip up I had in class. On average, I used the iPad for 5–10 minutes per lecture, and the vast majority of that time, I wasn’t connected to the Internet. On March 7th (the first Friday of Lent), I forgot to load the quiz/exam onto my iPad ahead of time. But the fix was simple: I could just connect to the Internet, download the file off the cloud, and be good to go.
So, that’s exactly what I did. What I forgot to do was to shut off the wireless connection after downloading the document. As I was going over the solution to a problem, the familiar chime of a Facebook message erupted from my iPad along with the following notification:
The full message (which is truncated in the push alert) was:
Funny stuff. One of the many reasons I love my wife is her fantastic sense of humor. But at the time, all I remember seeing was “no meat” as I desperately tried to make the notification go away. The class was laughing pretty hard, but I wasn’t sure if it was at the content of the message or just the fact that a message had unexpectedly interrupted class. My worst fears were confirmed later in the day, when I had Tara re-send the message so I could see exactly how much of it showed up on the screen. I was hoping the worst of it was truncated away. Unfortunately, the worst of it was not.
I was pretty mortified, but I got over it. My main sources of solace were that (i) the students were a pretty cool group, (ii) the statement was a joke, and (iii) it could’ve been much worse considering other subjects Tara and I have discussed by text message.
At least my students were entertained by the exchange. I was able to find the Twitter accounts of a few of them by searching for my name, and sure enough, the incident made their feeds:
Anyway, the take-home message is to put your iPad in “airplane mode” or turn off push alerts (and texts) to avoid disruptions and potential embarrassment during class. Or you can just marry a prude.
Some lessons are learned the hard way.
