I have always been one of those teachers who likes to show a lot of stuff on the screen. Before projectors, I displayed graphs, charts, images, and graphic organizers using a TV or overhead projector. I have always loved supporting what I have to say with visuals. So, it should come as no surprise that my computer, or any computer, is a necessary resource for my teaching.
I also like to switch back and forth between media. I am that guy who always has about 10 tabs open in a browser, and an addition 5 programs running on my computer. I switch between slides to documents to video to applications. I'm sure this drives my students crazy, but they get used to it. One thing I never got used to was being trapped behind my computer while I teach. I am definitely not one of these roam-the-room types, but I don't like to stand behind my computer and constantly have to look down at my screen. Since I utilize far more tools than just PPT, the little clicker thing never really worked for me. What I have always wanted is a miniature control panel that fits in one hand and allows me to switch seamlessly between apps and media, and even mark up that media for emphasis.
Well, during the Fall semester this capability literally fell at my doorstep when my department bought me an iPad. I had always wanted to use an iPad, but I didn't want to spend the money. I tend to be a late adopter when it comes to new devices. Anyway, I got the news from my dean that I would be getting an iPad, so I began researching ways to use it as a mission control for teaching.
My first task was to figure out how to mirror my iPad on the screen of my MacBook Pro. I discovered there are basically two ways to do this. You can use the iPad as a remote desktop and control the computer using the device. I tried PocketCloud, Doceri, and Splashtop 2. PocketCloud never really worked for me. I would be logged in, but I would have trouble connecting my two devices. Doceri worked pretty well, and even allowed me to mark up the screen, but it cost money and I didn't really like trying to find things on the screen. Besides, I was far more interested in teaching from the iPad apps than I was using the programs on my computer. Splashtop actually works really well, and I was able to get it for free. However, it is still just a remote view of my computer, which is not what I want. I much prefer the interface and ease of use of the iPad.
To keep this short, I settled on AirServer to mirror my iPad on my MacBook. There are a couple of programs that do this, and I liked this one best after downloading a couple of demos. AirServer fools your iPad into thinking your MacBook is an Apple TV, so you can use the built-in AirPlay to wirelessly mirror your device. For AirServer to work, your MacBook and iPad must be on the same wireless network. My university is very strict when it comes to using the wireless network, so this kind of thing is blocked. I found out, however, that I can pair my MacBook with my iPad using Bluetooth, and it works just the same. The only hiccup is when I try to stream video from the iPad to the MacBook via Bluetooth. It almost always freezes, so I have started playing video files directly from the hard drive. Other than that, this is a great solution that has not failed me yet.
The next thing I had to do -- and I am still doing -- is find apps that enable me to enhance my teaching with the iPad. I mean, if there is no value added, then why spend $12 for AirServer and bother figuring out how to mirror the display? I did quite a bit of reading and researching different apps that do the things I want to do in my classes, and I have found a pretty nice set that I rely on regularly. Here they are by category.
- SlideShark: Easy to import and sync from the cloud, and maintains animations and formatting
- Explain Everything: A nice combo of slides and an interactive whiteboard. Also lets me record my talk and upload it directly to Google Drive or YouTube (which I have yet to do.) By the way, when I Google "explain everything," it gives me a definition for the word "everything." Now that's pretty funny.
- SugarSync: This lets me sync everything (that I want) from my computer to the cloud. I can then access it from the iPad and send it to just about any app.
- Google Drive: This basically does the same thing, with the added bonus of displaying Google Docs, which I use a lot. This interface is also much better for images and PDFs.
- Socrative: This is a clicker app that still just blows my mind. I hope it stays free forever, but I'm sure it won't. I can send out quick polls to my class, both forced-response and open-ended. I can also create quizzes and exit tickets, and have the results e-mailed to me in a spreadsheet. I will probably write exclusively about this app later.
In order to demonstrate how this works, I have created a short video of how I move between apps during one of my class meetings. This is unedited, but you will get the point.
