Teachers juggle lesson prep, grading and communication across dozens of browser tabs, and a small set of extensions can remove real friction from that routine. Screen recording is one of the highest-value additions, since a single recorded explanation can replace repeating the same instructions to each student or class.
Recording lessons and explanations
Loom records your screen, your camera, or both, and turns the result into a shareable link within moments, without needing to upload a file to a separate video platform. This suits recording a worked example, a feedback walkthrough on a student's assignment, or instructions for a substitute teacher to follow.
What to look for beyond a screen recorder
Look for extensions that clearly state what data they collect, since many are used on school-managed accounts with student data nearby. Prefer tools with a free tier so you can trial them before committing, and check that the extension is actively maintained rather than abandoned, which matters for security over a school year.
Fitting extensions into a school Chrome setup
Many schools manage Chrome through Google Workspace for Education, which can restrict which extensions install. Check with your IT administrator before relying on a new tool for daily teaching, and prefer extensions that work without needing admin rights to configure, so a policy change doesn't break your workflow mid-term.
