I used clickers twice in my high intermediate grammar class. As others have said, the students loved it! It was fun and a non intimidating way to see how much the students comprehended. Judging from their answers, I saw where I may need to spend more time reviewing.
The actual creation and implementation of the clickers was pretty easy. Yes, I made errors, but I can see the process getting quicker. The instructions attached to the clickers themselves is excellent!
I will continue to use clickers in my spring grammar class and perhaps another class. They are a great way to start the course.
Thank you Tom and Amarjit for all your help.
