In a large online class, a teacher might give a lecture to as many as a thousand students. To bing a manageable amount of interactivity to such a large class, you can organize the students into much smaller groups and give each group their own small classroom (or “breakout room”). Here, the students can engage in real-time audio and video discussion while still listening to their teacher. Four students is the recommended size for a small classroom and the number of small classrooms is unlimited. You can also assign a teaching assistant (TA) to each small classroom, if desired.
Agora calls this use case a Breakout Class. It combines the advantages of exposing large numbers of students to high-caliber courses and teachers with the benefits of small-group discussion, which enhances student engagement. This arrangement is well suited for such scenarios as language training for young children and K-12 education.
|Real-time messaging||The teacher, students, and TA can all chat with each other through text messages.|
|Whiteboard||The teacher can share a Powerpoint slide, a Word or PDF file, or even an audio or video file on it.|
|Recording||The teacher can record the class and share the recording through a link for future review or evaluation.|
|Class management||The teacher starts or ends the class, and manages the students' privilege for sending audio, video, or real-time messages.|
|Device and network test||Before the class, the teacher can test whether the microphone and camera are working properly. During the class, both the teacher and the students can monitor the network quality in real time.|
|Screen share||The teacher can share the screen with the students.|
