I use it when teaching my golf unit. I am lucky enough to be able to use a room with a smart board in on my way out to the "driving range" (some golf mats with flags set out in the distance) that I set up for practice. I will show a very short clip of different techniques such as driving, chipping, pitching etc just to give the students a very concrete and visual demonstration of the technique. I then follow this up with my demonstrations outside. I also like this technique as I use videos of famous golfers so the kids get into it a little more as they recognize some of the golfers. I would love to be able to record their shots and show them back on the smart board, but it is just too unrealistic and time consuming for the amount of students that I have.
