My Take
It was an excellent review/summarization tool as it made participants think about the evening's learning.
How I Use It
I used this with teachers & principals during a Pro-d session I presented. It was the review at the end of the session. I knew participants would be excited to use it, but I was not prepared for the level of competitiveness! There were 100+ people logged in. You could have heard a pin drop while people were waiting for the next review question!
