I never got a chance to use Clickers in my classroom before.  They look like a great resource.  I think they would be a great morning start or could be used as a quick check after recess.  The students could pick them up on their way in, have them turned on and ready, and then be ready to start when the teacher turns on the test.  I like the way they can answer many different types of questions.  They can do numbers, T/F,  fill in the blank, multiple choice, etc.  In math, a teacher could put up a story problem.  The students could work on it and then fill in the answer. 

Another great thing about clickers is that it gives the teacher the ability to do a quick survey to see if the students are grasping the concept.  After the students have all answered, the teacher can go to the graph and check out the results.  If the students are consistently getting them correct, the concept has been mastered. 

By having every child use the same clicker every time, a teacher will be able to look at individual scores and it can be used as a great assessment piece.  I am not saying use it for every assessment, but I think it would be a great tool every once in a while. 

I really liked how you could bring in PDF's to build your test.  This would make it a lot easier because you wouldn't have to type every test from scratch. 

Ialso really liked how you could still use the paper test, but have the students respond to the test using their clickers.  This would make for very quick correcting.  I think would still have the students hand in their work.

One drawback to Clickers is that they might take some time at first.  Like any new tool or routine, it takes students a little while to get the hang of it.  Clickers will be the same way.  Yet, students catch on really fast, and I bet it wouldn't take long before they have the Clickers
