I've started using AhaSlides in my post secondary classroom. Most of my students have access to a cellphone or a computer during class time. So far I've used the word cloud: what words would you use to define-whatever topic we may be discussing. For example, it my Ethics class-what words do you think reflect the word Ethics-students type in a response and it appears on my screen building a Word Cloud. Also, can do quick checkin with students during the class period. They send their response "yes" or "no" and a graph is made showing the percentages. There's a bunch more options in AhaSlides that I have no explored yet. And the best part, its FREE!
