About the project

Agora e-Education is a sample project provided by Agora for developers in the education industry, which demonstrates how to use Agora Edu Cloud Service, Agora RTC SDK, Agora RTM SDK, Agora Cloud Recording, and the third-party Netless whiteboard SDK to quickly implement basic online interactive tutoring scenarios.

Applicable scenarios

Agora e-Education supports the following scenarios:

One-to-one Classroom: An online teacher gives an exclusive lesson to only one student, and both can interact in real time.
Small Classroom: A teacher gives an online lesson to multiple students, and both the teacher and students can interact with each other in real time. The number of students in a small classroom should not exceed 16.
Lecture Hall: Thousands of students watch an online lecture together. Students can "raise their hands" to interact with the teacher, and their responses are viewed by all the other students at the same time.
