No hands up please

Visiting a class once, my attention was caught by a boy, call him Tony, who at every opportunity for ‘hands up’ was as energetic in his ‘pick me, pick me’ actions as donkey in Shrek.

Chatting after the lesson, the teacher was bemused over Tony’s willingness, as he wasn’t that mathematically confident.

Having watched the lesson unfold it was clear that the teacher did what many teachers do: wait for several children to put their hands up before selecting someone to answer. I think Tony had figured out that the easiest way NOT to get picked was to be the first person to volunteer the answer.

The routine of ‘hands up’ is so ubiquitous in maths lessons that it can seem as natural as the sky looking blue, water feeling wet and Cliff Richard staying young.

But just because ‘it’s always been that way’ isn’t a good reason to carry on with some classroom practices. And there is good evidence that ‘hands up’ may not be the best practice.

How do you know if you are good at maths?

Dropping into a maths class I will often ask the children this question. There is a remarkable degree of agreement in the answers, which are usually along the lines of:

You’re good at maths if you can do it quickly and easily.

The practice of ‘hands-up’ for answers perpetuates the belief of speed as being the essence of being good at maths. Children who need a bit longer to figure things out simply don’t have the time they need or are discouraged when others around them get a hand up first.

The psychologist
Carole Dweck has looked at the downside of such an attitude to learning and one of her perhaps surprising findings is that such beliefs hamper successful students as much as the less successful.

If you’ve been successful at school maths because you can do what is set without much effort, then what happens when the time comes (and it will) that you meet some maths that isn’t easily done and requires more effort? Dweck’s research shows that many learners then think along the lines of ‘perhaps I was wrong, I ‘m not that good at maths after all’ and conclude that maybe maths isn’t for them.

Behind this, Dweck argues, is whether learners view mathematical ability as a gift—something that you either have or not - or whether they view it as something that can be developed through practice and effort -
a growth mindset.

The message is clear over-emphasis on quick answers perpetuates the ‘gift’ view of mathematical ability. ‘ Hands up’ leads to everyone losing out mathematically: the lower attainers in the short term, the higher attainers long-term.

A quiet ’thumbs up’ (held still against the chest) can still signal to the teacher when learners are ready, provide a calmer space within which to think, and dispel the myth that mathematical ability is all about speed.
