Zoom in an online collaboration tool provides virtual rooms where participants communicate and share information, typically within four primary use-case models — small group work, review sessions, interactive presentations, and virtual office hours. With the rapid shift to online learning resulting from the COVID pandemic, this service is also being used to hold fully virtual class meetings, and Hy-Flex classroom meetings, in which students are both present in a face-to-face classroom and virtually through this synchronous tool.
