How to record a course lesson on a Chromebook

You have a lesson to teach, but you want students to be able to watch it later. A screen recording can capture your slides, browser demonstration, voice, and optional camera view in one video.

Use the Screen Recorder to capture a browser tab, a window, or the Chromebook screen. Set up your lesson first, then make a short test recording so you can catch audio or screen problems before you teach.

Prepare and record the lesson

1. Open the Screen Recorder on your Chromebook. It runs in the browser, so there is nothing to install. Screen Recorder does not work on phones.
2. Get your lesson ready before recording. Open the slides, web pages, or other materials you plan to show, close unrelated tabs, and put any private student information out of view. Turn on Do Not Disturb from the Chromebook quick settings to reduce notification pop-ups.
3. Choose what to capture when the browser asks. Select a tab if the lesson stays in one web page, a window if you will demonstrate one app, or the entire screen if you need to switch between different windows. The whole-screen choice also records anything else that appears on the display.
4. Choose whether to include sound, your microphone, and your camera. Allow the browser to use the microphone or camera if you select either one. For a spoken lesson, check that the intended microphone is selected. Use the camera only if you want students to see you.
5. Make a short test recording. Speak at your normal teaching volume, show a slide or web page, stop the recording, and play it back. Check that the text is readable and your voice is clear before recording the full lesson.
6. Record the lesson, then stop the recording when you are finished. Save the resulting video where you can find it and review it once before sharing it with students.

A test of 10 to 20 seconds is usually enough to check the screen, microphone, and playback. If your lesson includes sound from a web page, test that too. The audio choices available can depend on the capture type and browser.

Choose the right recording setup

Record one tab for a slide or web lesson

Choose a browser tab when all the teaching content is in one page. This keeps unrelated tabs and desktop items out of the video. It is also a good choice when you need sound from that tab, such as a video embedded in a lesson. Confirm that the test recording captured the sound you need.

Record one window for an app demonstration

Choose a window if you are teaching with one application and do not need to show the rest of the desktop. This keeps other open windows out of the recording. If you switch away from the selected window, check your test to see what viewers will see during the switch.

Record the whole screen to move between materials

Choose the entire screen when the lesson requires switching among slides, browser tabs, or multiple apps. Before you begin, close personal messages and unrelated documents. Move the cursor away from important text when you are not using it, because the cursor may appear in the recording.

Add your voice or camera only if the lesson needs them

A microphone adds your explanation, while the camera can show your face alongside the lesson if the recorder offers that option for your setup. Keeping the camera off can make the lesson simpler and avoids showing the room behind you. In either case, play back a test to confirm the result matches what you intended.

Fix common recording problems

1. Check the capture selection. If students see the wrong content, stop and start again with the right tab, window, or screen. If you chose a tab, keep the lesson in that tab during the recording.
2. Allow the required permissions. Use the browser's site controls beside the address bar to allow microphone or camera access, then reload the page and try again. The browser also asks you to choose what screen content to share.
3. Check the Chromebook microphone. Open Settings › Device › Audio, choose the microphone you intend to use if more than one is listed, and check its input level. Speak during a fresh test recording and listen to the playback.
4. Reduce interruptions and background load. Turn on Do Not Disturb, close extra tabs and apps, and connect the Chromebook to power for a long lesson. These steps can reduce pop-ups and help keep the recording responsive.
5. Reload the recorder and try again. If the screen chooser or recording does not start, reload the page and repeat the permission prompts. Close other browser tabs that are using the camera or microphone, then test again.
6. Restart the Chromebook. If permissions look correct but capture still fails, restart the device and reopen the recorder. If your school manages the Chromebook, an administrator may control screen capture or microphone access.

Keep the recording classroom-ready

Use a readable browser zoom and keep the important lesson content away from screen edges. Avoid typing passwords or opening student records while recording. If you make a mistake, pause, repeat the explanation, and trim the mistake later if needed rather than restarting the whole lesson.

Screen Recorder runs in your browser, and recordings stay on your device. Check your school’s rules before sharing a recording that includes students, names, voices, or private class information.
