Three of the tools, I have already discovered and use regularly: Kahoot!, Socrative and Flubaroo. These three are free, easy to use and work great.
The three of the other tools: Plickers, ForAllRubrics and ClassCharts look very useful and I am exploring how I would use them in my classes. Although some of these are more for K-12 teachers, but I can see how I could use them with my university classes.
The seven tool: MasteryConnect, looks like it would be very useful for K-12 teachers but I don’t see how I could use it.
Check this out. The tools are great, free and Erica does a great job reviewing them.
