"I’ve spoken to a lot of administrators about what they look for when performing teacher observations. One of the comments I heard over and over again was, “I want to see the teacher circulating among the students.” You can’t do that if you’re attached to the interactive white board. I have an AppleTV in my classroom hooked up to a projector. Using my iPad and AirPlay, I can wirelessly mirror any content on my iPad to the screen at the front of the room. The real advantage is evident during collaborative activities. Students can use their own iOS devices to connect to the AppleTV to share their work with the rest of the class. I can be anywhere in the room and still run my lesson. I can pull up sound and video clips on my iPad and instantly share them with my class without being attached to any particular location in the room."
