If you’re using iPads in your classroom, at some point you’ll want to be able to display your iPad screen to the entire classroom. Fortunately, a couple methods exist that allow teachers to do just that.
The most common method (although not the one I recommend for Mac users) is to mirror your iPad’s display using an Apple TV device that is connected to your classroom projector via a HDMI cable. Mirroring (showing what is on your iPad display) is done using an iPad feature called AirPlay introduced with the iPad 2. Unfortunately, you cannot mirror your iPad display using the original iPad. You need an iPad 2 or the new iPad and you need to be running the latest operating system for the iPad.
AirPlay is a fantastic feature of the iPad (and iPhone) that lets you stream your iPad data to an Apple TV and then have the output go from the Apple TV to an HDMI compatible device like your TV set. The original AirPlay only allowed you to stream video and audio; however, with the introduction of iOS 5, it now allows users to stream their iPad display to their Apple TV allowing them to see their iPad display on their TV set.
To utilize this method of projecting your iPad display, you’ll need to purchase an Apple TV device and an HDMI cable. The HDMI cable needs to be long enough to go from the Apple TV to the projector. The good news is that you can place your Apple TV device near your projector so the cable doesn’t need to be long. Your projector must also accept HDMI input. If you have an older model projector that does not support HDMI, you will need to purchase an additional piece of hardware to convert your HDMI signal to something that is compatible with your projector. An Apple TV device retails for $99 and a HDMI cable costs approximately $20. If you need to convert your HDMI signal, you can purchase a HDMI to VGA cable for under $10 but you won’t be able to hear the iPad audio. The only other requirement for this configuration is having a wireless network to send the signal from your iPad to your Apple TV.
The second method is actually a lot easier to implement, provides you with more options for how your iPad’s display is projected, and it’s also a lot less expensive.
This method uses a software program called Reflection that is now available for the PC as well as a Mac. Reflection is a relatively new software program that simulates an Apple TV device. When Reflection is running on your computer, your iPad’s AirPlay will detect your computer and give you the option of mirroring your iPad’s display on your computer screen. Since you can see your iPad’s display on your computer, all you need to do is connect your computer to a projector and voila, your iPad’s display is projected to the entire classroom.
To utilize this method on a Mac, you will need to purchase the Reflection software program for the Mac and you’ll also need a Mini DisplayPort to VGA Adapter so you can connect your Mac to your projector. The Mini DisplayPort is a standard port on the Mac. One end of the adapter fits into your Mac’s Mini DisplayPort and the other end connects to a standard VGA cable that is then plugged into your projector. The Reflection software is currently priced at $14.99 and the Mini DisplayPort to VGA Adapter retails for $29. To save money, you can purchase a 3rd party adapter online for under $10. Once again, the only other requirement is that you have a wireless network so your iPad can talk to your Mac. This is the same requirement for Method One using the Apple TV.
The Reflection app allows you to adjust the appearance of your iPad’s display on your Mac’s computer screen. For example, you can change the position, size, and orientation of your iPad display. You can also set the display to full screen and you can even change the display so it shows an iPad frame around the display making it appear that you’re looking at an actual iPad. This would be helpful for younger students to make the connection between the iPad and the projected image.
