This section describes how to implement a web client for the teacher.
This flowchart shows the major logic of the following functions:
- The teacher joins and leaves the classroom:
Integrate the SDK
Refer to the following table to download the SDKs, and integrate the SDKs into your project.
|Product||SDK download||Integration guide|
|RTC (Real-time Communication) SDK||Agora SDK for Web||Start a Video Call|
|RTM (Real-time Messaging) SDK||Real-time Messaging SDK||Peer-to-peer or Channel Messaging|
|Cloud Recording||/||Record by RESTful API|
|Agora Edu Cloud Service||/||Agora Edu Cloud Service quickstart|
|Whiteboard||White SDK||Whiteboard quickstart|
Core API call sequence
Refer to the following diagram to implement the various functions in your project with the Agora RTC SDK, Agora RTM SDK, and Agora Edu Cloud Service.

For more features and functions available for an online class, you can refer to the following:
Monitor the network qualityUse the
on("network-quality")callback of the Agora RTC SDK to monitor the last-mile uplink and downlink network quality of every user in the channel. For more methods for reporting the real-time network quality, see the following guides:
Mute the local audio or videoCall the following methods provided by the Agora RTC SDK:
unmuteAudio, to stop or resume sending the local video stream.
unmuteVideo, to stop or resume sending the local video stream.
Mute the remote audio or videoUse both the Agora RTC SDK and Agora RTM SDK to implement this function:
sendMessageToPeeron the teacher's client to send a peer-to-peer message to the student, asking them to mute their audio or video.
- Call the corresponding
mutemethods on the student's client to mute their local audio or video.
