As an educator, your primary goal is to create a safe, respectful, and effective learning environment. In a physical classroom, you have established routines for this: you close the door to prevent interruptions, you set rules for speaking, and you manage the flow of the conversation.

But how do you replicate this in a virtual classroom? An unsecured online meeting can quickly devolve into chaos, with uninvited guests, background noise, and constant interruptions.

This guide will walk you through the simple but powerful tools available in Plug-N-Meet that allow you to take control of your digital classroom. Think of these features as your new classroom management toolkit, designed to ensure your online sessions are as safe, private, and productive as your in-person ones.

1. Lock the Door: The Waiting Room​

You wouldn't let just anyone walk into your classroom off the street. The same principle should apply online. The Waiting Room is your digital lobby, giving you complete control over who enters your session.

  • How it Works: When you enable the Waiting Room for your class, any student who clicks the join link is placed on a "waiting" screen. You, the teacher, will see a notification and a list of everyone waiting to get in. You can then admit them one by one or all at once.
  • Why it's Essential:
    • Prevents "Zoombombing": This is the single most effective way to stop uninvited guests from disrupting your class. If you don't recognize a name, you don't have to let them in.
    • Control the Start Time: It allows you to prepare your lesson materials and admit all students at the same time, ensuring everyone starts on the same page.

How to Enable it: You can enable the Waiting Room in your room settings when you create the class in your LMS (like Moodle) or via the API.

2. Set the Rules: Granular Lock Settings​

Once your students are in the room, you need to set the ground rules for participation. Plug-N-Meet's Room Lock Settings panel is your command center for this.

  • Lock Microphones (Your Most-Used Tool): This is the equivalent of asking the class to be quiet while you're speaking. It mutes all participants and prevents them from unmuting themselves. This is essential for lectures, presentations, or when a specific student is speaking.
  • Lock Webcams: In large classes, having dozens of webcams active can be distracting and consume a lot of bandwidth. Locking webcams helps focus attention on the speaker or the shared content.
  • Lock Public Chat: While chat is a great tool, it can sometimes become a source of distraction. You can temporarily lock the chat to bring focus back to the lesson, and then unlock it for a dedicated Q&A session.
  • Lock Screen Sharing: Keep this locked by default to prevent students from accidentally taking over the presentation. You can unlock it when you want a student to share their work.

Pro Tip: Use these settings dynamically. Start your class with everything unlocked for a few minutes of social time, then lock microphones and chat when the formal lesson begins.

3. The Gold Standard of Privacy: End-to-End Encryption (E2EE)​

For sensitive conversations, such as a one-on-one meeting with a student or a parent, you may need the highest possible level of privacy. End-to-End Encryption (E2EE) provides a mathematical guarantee that no one—not even the server administrator—can access the audio or video of your conversation.

  • How it Works: When E2EE is enabled, the video and audio are encrypted on your device and only decrypted on the recipient's device.
  • When to Use It: This is ideal for any situation requiring absolute confidentiality, such as discussions about grades, student well-being, or any other private matter.

How to Enable it: E2EE can be enabled on a per-room basis. Our guide on How to Enable E2EE explains the simple steps. It's important to note that when you enable the highest level of E2EE, features that require the server to "see" the media, like cloud recording, are automatically disabled for your protection.

Conclusion: You Are in Control​

A secure and productive online classroom doesn't happen by accident. It happens by design. By using these simple but powerful features, you can move from being a passive host to an active and effective classroom manager.

Start with the Waiting Room to control who enters, use the Lock Settings to manage the flow of conversation, and deploy E2EE for sensitive discussions. With these tools at your fingertips, you can create a virtual learning environment that is just as safe, private, and conducive to learning as your physical classroom.
