Don’t get me wrong, I don’t have anything against mobile phones (just an allergy, as my students know).
But I recently had a dream-like experience of teaching a class where students did not have mobile phones anywhere near them. Dream-like, because the mobile phone is every student’s partner-in-crime during classes. So much so that sometimes I miss students who engage in good old doodling or hangman.
These students had deposited their phones in a basket (they did not have a choice) and let themselves into the uncharted territory of sitting in class without the “adult pacifier” at hand (see image, research by Shiri Melumad and Michel Tuan Pham). Not even laptops or tablets. The credit for the mobile-free class goes to the HR manager. I spoke with Pradnya for just two minutes, but her willpower was evident, and her good intentions were obvious.

And so, I taught my first ever classroom where mobile phones were absolutely absent. Not just invisible or inaudible, but really absent from the minds of the students.
When the mobile phone is present, it has a pull, it is just waiting to be checked, and can’t be denied. So even if a student decides not to use the phone, but the phone is on the desk or even in the bag, the silent call of the phone continues to distract (see image, research by Adrian Ward, Kristen Duke, Ayelet Gneezy and Maarten Bos). In the mobile-free class, there is no such distraction.

Now, I do not yet have proof, but as someone who has taught graduate students and executives for about 800 hours, low distraction classes (classes where students oblige with my request to put their phones away) operate at a higher plane of engagement and learning compared to high distraction classes. The absence of electronic devices activates the one device which will accompany us through life, even in the age of AI – the brain!
Students often don’t get an opportunity to notice the benefits of a mobile-free class, and this creates an understandable resistance to putting away the phone. But objective research and my experience concur on this observation. And every year there are a few students who thank me (Aparna D in The CMO’s Playbook was the first!) for requesting that they avoid using the phone. And that’s where the proof of the pudding lies… in switching off the phone and letting the class take you places.
So next time your teacher requests the class to put away your phones, do so with a smile. It’s one small step for a student, one giant leap for education!
Here’s all of us after six hours of refreshing freedom!
