Feedback you get on paper at the end of a course is often rushed, and feedback by email arrives weeks later from a handful of students. The best moment to ask is in the room, right after the unit wraps up, when the experience is fresh and everyone is present. A QR code on the final slide makes that take two minutes.
Instructors also ask for feedback repeatedly: after each unit, at midterm, at the end of the course. A dynamic code lets you print it once, in your syllabus, on the classroom wall, or in your slide template, and change which survey it opens each time. Responses stay organized by survey, and the code students recognize never changes.
Where to place it
- On the closing slide of each unit, shown during the last five minutes of the lesson.
- In the course syllabus, so students know from day one how and when feedback is collected.
- On a small poster near the exit, for students who prefer to respond after leaving class.
- On the cover sheet of the final exam or assignment, to be scanned once work is handed in.
- In the header of the course page on your learning platform, linked to the current survey.
Tips that improve scans
Guarantee real anonymity
Students only give honest feedback when they trust it is anonymous. Turn off automatic email collection in your form tool, avoid asking for section and student number together, and never try to match handwriting style or timing.
Ask open questions well
"What helped you learn most?" and "What one change would help?" give more usable comments than "Any other feedback?" Keep the survey short enough to finish on a phone in three minutes.
Size for the room
A projected code should be large enough to scan from the back row: roughly a quarter of the slide height. Leave it up for the whole response window rather than flashing it briefly.
Show what changed
At the start of the next unit, share one or two changes you made from the last round. Students who see their feedback used are much more likely to respond thoughtfully next time.
Midterm survey to final survey
A college instructor printed a feedback code in her syllabus and on the last slide of her template. At midterm it opened a short check-in survey; she adjusted her pacing based on what students said. In the final week she built a longer end-of-course survey and pointed the same code at it. Students scanned the code they already knew, the midterm and final results stayed in separate forms, and she never had to send out a new link.
