In a One-to-one Classroom scenario, an online teacher gives an exclusive lesson to only one student, and both can interact in real time. This typical one-to-one scenario can find uses in online tutoring, language lessons, music lessons, and more.
This article describes how to use the Agora SDKs to implement a One-to-one Classroom scenario.
You can use the Agora SDKs to implement the following features for your project.
|Real-time communication||The student attends the teacher's online class. During the class, both can see and talk to each other in real time, creating a positive interaction.|
|Real-time messaging||Both the teacher and the student can 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.
The teacher and the student can also write things collaboratively on the whiteboard.
|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 student's 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 student can monitor the network quality in real time.
|Screen share||The teacher can share the screen with the student.|
