1. I also created a Today's Meet. http://todaysmeet.com/Kindergarten_Science_SBISD
I also created an Edmodo. http://www.edmodo.com/library/v2/
2. I will use these with teachers to get instant feedback on lessons and to provide guidance to ensure that the lesson was successful. I will also use them during meetings to help clear up misconceptions and to manage time better.
They encourage participation by having students and teachers provide comments before or during a meeting or lesson. Teachers and students are willing to take a risk of typing in a question rather than raising their hands.
