Which technology is identified as a polling tool for interactive engagement?

Poll Everywhere is identified as a polling tool for interactive engagement because it allows users to create real-time polls, surveys, and quizzes that participants can respond to using their mobile devices or computers. This interactivity enhances the engagement of participants during presentations, lectures, or workshops, facilitating immediate feedback and interaction that can enhance learning outcomes.

Other options do not serve as polling tools in the same way. Slideshare predominantly focuses on sharing and presenting slide decks, making it more of a static resource rather than an interactive engagement tool. Microsoft PowerPoint offers features like quizzes and polls, but it does not specialize in real-time interaction like Poll Everywhere. Canvas LMS is primarily a learning management system that supports course content delivery but does not feature interactive polling explicitly designed for real-time audience engagement.
