Maths trauma is real, but it can be avoided. Here’s how.

By Oxford Insight Mathematics author and lecturer in the School of Mathematics and Statistics at UNSW Sydney, Daniel Mansfield

Maths trauma, the issue highlighted in the US edition of The Conversation, is real.

If a student never masters irrational numbers then when they come to trigonometry (which involves lots of irrational numbers), they will receive a constant bombardment of negative reinforcement, and sooner or later even the most confident student would have to acknowledge the overwhelming evidence that they are ‘no good at maths’.

The path through mathematics is full of such pitfalls, and sadly many who fall by the wayside do not return. How can we restore maths-confidence in those who have lost it? I don’t believe there is a single answer to this question, but here are some thoughts.

Someone who is traumatised by mathematics cannot simply be expected to just try again, but just try harder, and reminding them that they will need this skill in the real world will just compound the shame of failure. So, instead of trying to put them back on the road they fell off, find them a different road.

I teach first-year mathematics students, and I recall one student in particular who was traumatised by simultaneous equations. He would flatly refuse to apply the standard high school methods. But he would gladly solve simultaneous equations using a matrix. The matrix method is technically excessive, but for him it had the single important advantage of being different.

Now, let’s imagine a student who is unable to perform arithmetic. Arithmetic is the goal, and the fastest path is memorisation. But the student’s experience on this path has been traumatic and now the student reasonably believes that further attempts along these lines will only lead to failure. How could a teacher help? You might like to pause for a moment and consider what you would do or have done to help such a person. Here are some ideas that could work in this situation:

  • Teach them to use an abacus. Arithmetic can be understood as the purely physical activity of moving beads on a frame. Addition, subtraction, multiplication and division can all be performed by repeating a pattern with your hands.
  • Teach them binary arithmetic. Binary arithmetic looks strange to decimally minded people, but it is actually the simplest form of arithmetic. The idea of learning the binary number system might be both achievable and palatable because it does not immediately reignite traumatic thoughts.

Other ideas would be to use Cuisenaire rods, or modular arithmetic. These are just some of the many paths to understanding the fundamentals of arithmetic, and I’m sure there are many others besides. Mastering a different strategy doesn’t teach arithmetic as directly or easily as memorisation. The advantage is that the student can circumvent trauma by finding a different path to understanding.

The real question is matching the person to the path. Students do not need to stay and suffer on a path that does not work for them – they can and should get off and try something different. While arithmetic may be fundamental and even universal, it is a concept understood by humans and this human element permits an unlimited number of different and legitimate understandings.
