If you’re teaching online with Zoom, a handful of built-in features can make your sessions far easier to manage. Learning how to mute participants quickly, control screen sharing, use annotation tools, and adjust your meeting settings will help you deliver smoother, more professional online classes.

Tips for using Zoom for Online Teaching

If you’re teaching on Zoom, the most useful settings to ensure you know how to use are the participant controls, audio and video defaults, annotation tools, meeting security, and screen-sharing permissions. Understanding how to change these settings can make your online classes run more smoothly and professionally.

1. How Do You Mute Everyone in Zoom During Online Teaching?

If you are teaching online (or using Zoom for meetings), there are numerous times when you will want to mute all other participants.

You can do this by pressing ‘Manage Participants’ and then, on the next screen, clicking ‘Mute All’ at the bottom of that screen.

But what if you are sharing your screen and do not have the ‘Manage Participants’ option visible at that time on your screen?

The easiest and quickest way to ‘Mute All’ is to use a keyboard shortcut!

All you have to do is press the ‘Alt’ and ‘M’ at the same time if you use a PC (it’s Control+M if you are using a Mac computer).

If you then want to ‘Un-Mute’ everyone, then use Alt + M again to reverse the mute.

2. How Do You Turn Off Your Video Before Joining a Zoom Meeting?

You do not have to use this Zoom hack, but my advice is to change the settings for your video so that your video is turned off until you choose to allow the video.

By default, when you first load Zoom onto your computer, unless you change the video settings, it will be set to your video camera set to show you automatically as soon as you join a meeting.

Most people join a Zoom meeting ready to appear on camera.

As a precaution, though, I think it is a much better idea to choose at what point to let the video of you show in the meeting so that you can be sure that you are ready to be seen.

To change the default setting, go to Settings. To get to settings, just click the cog.

Next, click ‘Video’ on the settings page, and then under the ‘Meetings’ heading, tick the box where it says ‘Turn off my video when joining meeting’.

3. How Do You Use Zoom’s Annotation Tools for Online Teaching?

One feature when using Zoom for online teaching that I find incredibly useful and that many of you may not be aware of when using Zoom is the ‘Annotation’ feature.

Imagine you are sharing your screen (letting others in the online meeting see your screen) and that you want to highlight something so that everyone can easily see what you are trying to show them. With the annotation features, you can use a tool such as the ‘spotlight ‘ tool.

To see the annotation tools, you first want to click ‘Annotate’ in the Zoom bar at the top of your screen.

Once you have clicked ‘Annotate’ you will see the annotate tools and these include ‘draw’, ‘stamp’, spotlight’, and ‘eraser’.

The one I want to show you for now is the ‘Spotlight’ tool.

Once you select annotation, you see these options.

So, if you click the ‘Spotlight’ tool, you will then see, when you hover your mouse over something on the screen you are sharing, that a spotlight will show and help you to highlight to everyone what you are pointing at.

The best way to get used to the annotation tools is to spend 5 minutes playing around with the various tools.

4. Why Should You Join a Zoom Meeting With Your Microphone Muted?

When you enter a meeting or online class, whether as the teacher or as a student yourself, it is a much better idea to enter the meeting with your microphone turned off (muted) and then turn the microphone on once you are sure you are ready.

Why, you might ask?

Well, two main reasons. Firstly, you might be moving around and making other noises as you get settled and join the class, and you do not want to introduce any unnecessary noise to the class or meeting.

Secondly, it is not uncommon to be setting up and connecting to a meeting and for us to be talking to someone else as we do so, such as if we are finishing a phone call or chatting with someone in the same workspace.

Choosing exactly when to be included in the audio aspect of the meeting can save some unwanted embarrassment.

When you do want to have your audio (microphone) included, just click the ‘Join audio’ at the bottom left of the screen.

You can also press Alt = A to unmute your microphone!

5. Password Protect Your Online Classes in Zoom for Added Security

A serious issue when using Zoom for online teaching, as with anything you do online, is always going to be making sure that security is in place and that you are protected online.

With security in mind, one thing I recommend always doing if you are holding a private class (meeting) is to password-protect it!

You want to avoid what is known as ZoomBombing. ZoomBombing, in effect, is hackers taking control of your shared screen and putting their own images on your screen for your class to see (often disturbing images).

To ensure that you password-protect any private lessons and classes you create online, start by clicking ‘Schedule‘ on the main interface (see image below).

Set up a meeting with Zoom

Once you have clicked to schedule a new online class (called a meeting in Zoom), you will see the meeting schedule that you see in the image below.

What you need to do is make sure that the ‘Require meeting password’ is checked and that you enter a password.

You will then want to make sure that everyone who will be involved in your online class is given the password.

Schedule meeting with Zoom

Another thing you can do to make your online classes more secure, as an online teacher, is to go to the ‘Advanced Sharing Options’ (see image below).

In the advanced sharing options, you can then select ‘Only Host’ under the ‘Who can share?’ section.

Selecting only the host as the person to share will ensure that you can avoid anyone maliciously taking control of the shared screen.

6. Avoiding Others Entering the Virtual Classroom Before You, the Host

It is also a very good idea indeed to make sure that you, the host, are the first person to enter the virtual classroom, to ensure that the classroom is correctly managed.

If you were to allow others to join the classroom (or meeting) before the host joins, there is a greater opportunity for issues to exist in the classroom, particularly if you are holding training for anyone with the meeting link to join.

If you are holding a password-only classroom meeting and every student knows every other student, then you can potentially leave this tip if you wish.

So, in the options when using Zoom for online teaching, you first schedule the meeting, click on ‘Advanced Options’.

Under ‘Advanced Options,’ you will then want to make sure that you LEAVE the ‘Enable join before host’ box.

By default, this will already be unchecked, so if you have just downloaded and started using Zoom, you most likely will not need to change any settings.

It is worth checking, though, as making sure that you, as the host, are first to enter the digital classroom provides you with an added level of security in that you can better control the digital classroom from start to finish.

7. Use Breakout Rooms in Zoom for Online Group Activities in Your Digital Classroom

‘Breakout Rooms’ can be essential if you want to provide teaching online because it means that you can quite easily create small groups of students to work together, and this is especially good if you are using training course materials.

To run activities in your online classes that involve smaller groups working together (i.e., if you want to split the class into groups of 4 students in each group), you can do this very easily in Zoom for online teaching, using ‘Breakout Rooms’.

It’s a wonderful feature that makes teaching online just as easy as doing online icebreakers, online team-building games, and other training activities online.

Classroom lesson plans

Breakout rooms are very easy to use and are a wonderful feature.

When I first started using Zoom as a freelance trainer, I wondered how I would be able to take training materials such as ‘Introduction to Mindfulness’ and how I would be able to then use them to provide this course online.

The issue I thought would be finding a way still to use group activities in the classroom, but with Breakout Rooms, the solution already exists.

You can even pre-assign breakout room names and pre-assign (if you wish to) students to these rooms for when they will work in small groups during the online lessons.

Final Thoughts

Zoom for online teaching is a great option for virtual teaching, and you can generally manage things even more easily, in many respects, than you could in an offline classroom.

Assigning people to small groups has never been easier, for example.
