Your Video Call Isn’t A Classroom. Here’s What It Is.
Every ed-tech team hits the same wall eventually: your video call works fine for a meeting, but a classroom needs more. A teacher who can promote a student's mic, a whiteboard that stays in sync for forty kids, breakout rooms that don't fall over. Building that stack from raw WebRTC is a semester-long project by itself. So instead of building it, I set out to stand up Agora's Flexible Classroom…
Ed-tech teams often face the challenge of transforming a simple video call into an effective virtual classroom setting. While basic video conferencing tools can handle meetings, they fall short when it comes to managing student interactions, whiteboards, and breakout rooms in a classroom environment. Building a classroom on top of WebRTC, the underlying technology for real-time communication, is a time-consuming endeavor typically spanning a full semester.
To address this issue, the source material explores the use of Agora's Flexible Classroom, a pre-built solution that simplifies the process of creating a functional virtual classroom. The walkthrough begins by highlighting that Flexible Classroom is not just a video call widget, but rather a comprehensive classroom UI that includes layouts, roles, and interaction patterns.
It is built on top of Agora's real-time engine and offers low-latency video and audio, a real-time messaging channel, and an interactive whiteboard. The desktop version of the solution is packaged as an Electron app for Windows and macOS, abstracting away the complexities of signaling, reconnection handling, and other backend concerns.
The actual components of Flexible Classroom are pre-built scenes or modules, each encapsulating specific functionalities. These scenes include features such as live video and audio, screen sharing, a shared whiteboard, text chat, and engagement tools like handraise queues and live polling. Additionally, the system supports various roles and management features, including attendance tracking and built-in proctoring capabilities.
Setting up Agora's Flexible Classroom involves several straightforward steps. First, ensure that you have Git, Node.js 16, and Yarn installed. You will also need an Agora account with Flexible Classroom enabled in the console. A stable internet connection is crucial to avoid any issues related to real-time media ports. After installing the prerequisites, clone the desktop repository and navigate to the release/2.9.0 branch.
The next step is to install the submodules, which include the classroom UI, whiteboard bindings, and Electron shell. Finally, provide your App ID and certificate from the Agora Console in the .env file, and launch the application using the yarn dev command. Once launched, you can join a room as the Teacher role from one window and as a Student in another, demonstrating the functionality of the different user roles and the seamless integration of various features within the classroom environment.
