As part of a lesson on the Fibbonacci Sequence in a math class I created this AR trigger in LAYAR which led the students to a video about the Fibbonacci sequence on You Tube. Note to self: when making an AR trigger do not use an object like a watch. The trigger worked when I tested it right away but when my students tried scanning my watch at 3:30 the trigger would not work (DUH!) So we had to use the AR trigger that I had printed out. I used this in my grade eight gifted and talented math class. Perhaps you could use it in your own learning environment.
