BigBlueButton is web conferencing software designed to help schools and teachers share learning content with students from remote locations.

Key features include whiteboard, polls, emojis, session recording, live streaming, screen sharing, virtual classrooms, and breakout rooms. Teachers using BigBlueButton can share slides, video, audio, chat, and desktop with their students.

Built-in polling and lecture recording features enable teachers to increase student engagement. Teams can use the whiteboard to create annotations on screens that participants can view in real time.

BigBlueButton is open source software, meaning free for both personal and commercial use. However, the software must be installed on an Ubuntu Linux server, and installation and ongoing maintenance requires a deep, hands-on knowledge of the operating system.

Presenters can showcase any PDF or Microsoft Office document and annotate important topics using the BigBlueButton whiteboard feature. Students can chat with professors or fellow students in a private or public chat.
