QR Codes for Education
QR codes save class time and typing. Teachers can put a single code on a handout or slide so students open a video, a quiz or a reading list instantly on their own device, without spelling out long web addresses.
How to use it
Pick the resource
Choose the video, quiz, document or reading list you want students to reach quickly.
Create the QR code
Generate a URL code for that resource and download it as a PNG for slides or a printout.
Add it to materials
Drop the code into handouts, slides, library posters or classroom displays with a short label.
Check access rules
Make sure students can open the link with their school accounts, then test on a few devices.
Tips for best results
One code per resource
Clear, separate codes for each video or worksheet avoid confusion in class.
Add a short instruction
A line like "Scan to open the quiz" makes the code self-explanatory.
Print larger for sharing
A code shared by several students should be big enough to scan from a meter away.
Link only to safe pages
Point codes at trusted, ad-light pages so students land somewhere appropriate.
Best practices
Test on school devices
Check the code opens correctly on the tablets and phones students actually use.
Avoid login walls where possible
If a link needs a login, say so on the handout so students are prepared.
Keep codes high contrast
Dark codes on light paper scan reliably even on older projectors or prints.
Think about accessibility
Also provide the plain URL in text for anyone who cannot scan, so no student is left out.
Design examples
Homework handout
A code on a worksheet opening a tutorial video for revision at home.
Library poster
A code linking to an online reading list or e-book shelf.
Class slide
A code on a presentation slide opening a live quiz or poll.
Frequently asked questions
Teachers use them to share videos, quizzes, reading lists and documents instantly. A single code on a handout or slide gets every student to the same resource without typing a link.
No. Modern iPhone and Android cameras scan QR codes natively. Only very old devices would need a free scanner app.
Yes, as long as you link to trusted, appropriate pages. Always test the code and the destination yourself before sharing it with students.
They are great for it. A code on a worksheet can open a video explainer, extra practice or a reference page that students can revisit at home.
For a handout, 2 cm is enough. For a code shared by a whole class or shown on a wall, make it larger so it can be scanned from a comfortable distance.
