I don't like slides with too many words. I don't like presentations that leave the viewers with too much idle time. To overcome these issues, I've considered a balance of input and output between the audience and presenter.
Strategically placed questions throughout a presentation, cartoon analysis, and crowdsourcing cues are a few of the things I've used to break up the teacher-led talk. Adding polling questions without having to leave Google Slides was the perfect compliment to these strategies.
I realize that this could have been done using Microsoft PowerPoint and Poll Everywhere, but I don't have time to deal with the headaches of Microsoft Office. Google is far too efficient for me to ever go back.
