Pulling sticks isn't fair — here's what actually happens when you cold-call randomly

Every teacher has a jar, a cup, or a tin of lolly sticks somewhere in the room. The idea is simple: pull a name at random, and nobody can claim you've got favourites. It feels fair. It looks fair from the front of the room.

It isn't, and most teachers know it isn't — they just haven't had a better option.

The problem with "random"

True randomness is streaky. If you've ever flipped a coin ten times and landed on heads seven of them, you've felt it: short sequences of random events cluster in ways that feel unfair even when the process is technically fair. In a classroom, that means the same handful of confident hands get pulled two lessons in a row, while a quiet student at the back goes three weeks without being asked a single question.

Layer on top of that the very human tendency to re-pull when you land on a name you suspect won't answer — "let's try someone else" — and the stick jar stops being random at all. It becomes a mirror of who you already expect to participate.

The students who notice this fastest are the ones it affects most. They stop raising their hands, because raising a hand has never been what got them picked anyway.

Why this matters more than it seems

Cold-calling — picking a student rather than waiting for volunteers — is one of the most well-evidenced ways to raise classroom engagement and surface misconceptions early. But it only works as a fairness tool if students believe it's fair. The moment a class senses a pattern (real or not), cold-calling stops feeling like inclusion and starts feeling like a spotlight that lands on the same few people.

That's the quiet cost of the stick jar: it was meant to spread attention evenly, and instead it can end up doing the opposite — while still giving you, the teacher, the comforting sense that you've "asked everyone."

What actually fixes it

The fix isn't more randomness — it's weighted randomness. A name picker that quietly tracks who has been picked recently and nudges the odds toward students who haven't answered in a while gives you the same feeling of spontaneity in front of the class, but spreads participation properly over a week rather than a lesson.

It also removes the awkward moment of re-pulling. If the system is doing the weighting, you don't have to make a judgement call about whether to "try someone else" — you just go with who comes up, and the fairness argument disappears along with the dispute.

This is exactly the gap Classroom Hub's Classroom Screen closes. Its fairness-weighted name picker runs on the board during the lesson — same energy as pulling a stick, minus the bias nobody could see from the front of the room. Pair it with the objectives, timers, and bell ringer widgets already on the screen, and you've replaced four separate "front of class" tools with one.

If you've ever had a student tell you "you never pick me" and known, deep down, that they might be right — this is the bit of the lesson worth fixing first.
