The Q&A option is an excellent tool for students to use while watching a presentation. The fact that it can be done anonymously gives students the opportunity to ask any questions they may have. This is great for students that are afraid or embarrassed to ask something in front of everyone else. I also like that the question can be presented as a slide for everyone that is viewing to see. This allows the teacher to bring everyone’s focus to the question and to then to answer it for everyone as well.
