Teaching kids to fear maths will harm Britain's chances in the global economy

The prospect of learning maths scares us, but actually doing the proper stuff is rather enjoyable.

If someone were to give you a maths textbook, what would your reaction be? What about if you were faced with a set of sums to do? Or told you cannot graduate until you have taken a certain number of maths classes?

If these scenarios make you feel nauseous, you are probably an HMA – someone with a high level of maths anxiety. For some people, the threat of a maths test is equivalent to the prospect of walking down a dark alley in an unfamiliar city. People with extremely high levels of mathematics anxiety even experience physical pain.

We know this thanks to a study published, appropriately enough, on Hallowe’en. The research involved recruiting volunteers who rated high and low in maths anxiety. They were put into a magnetic resonance imaging scanner and given a range of tasks to do. Some involved maths quizzes; some tested verbal skills.

In the most illuminating part of the study, the volunteers were told whether it was maths or language tests coming up. The prospect of having their verbal skills tested provoked nothing remarkable in the brain scans. For those who were highly maths-anxious, the signal that a maths test was coming up created a surge of activity in the bilateral dorso-posterior insula. This is a region of the brain associated with the presence of physical pain and the reaction is the same as to a physical threat – you experience the urge to get the hell out of there.

Though many papers reported the research as justification for a fear of maths, it goes far deeper than that. The most important finding from the study is that when the volunteers started to do maths, all that anxiety and pain went away. The prospect of maths scares and sometimes pains us; doing maths is strangely enjoyable. Proper maths, that is – not the endless repetition of learned techniques such as multiplying fractions or ploughing through long division.

The way we teach mathematics is leaving many people mentally scarred. Allow students to develop a feel for numbers by letting them solve puzzles, and everything changes. The message from the Computer-Based Math™ Education summit held at the Royal Institution in London this month goes even further. Allow children to learn maths by using computers to solve problems and not only does the subject get easier, but they leave education ready to work in a world increasingly dominated by digital technology.

This idea is anathema to traditionalists, but something has to change. Just under half of the adult population can’t complete even primary-school maths problems. Adults with poor numeracy skills are twice as likely to be unable to find work; it’s no wonder they are also twice as likely to suffer from depression. Innumeracy leads to poor money management and problems with debt. On 7 November, the charity National Numeracy launched a partnership with the Nationwide Building Society to help people develop numeracy skills to manage their finances.

Economy class

Innumeracy will affect Britain’s ability to compete in a global economy, too. At the beginning of October, the Royal Academy of Engineering announced that the UK can maintain its industrial output only if British universities produce 10,000 more science, technology, engineering and maths graduates every year.

It’s not clear where they are going to come from, because each one will need to leave school with decent maths skills.

If things carry on as they are, we can abandon hope of a role on the world economic stage in the future, all because we’re inflicting pain in maths class. As a doctor might say, if it hurts that much, you’re probably doing it wrong.

The problems with ending encryption to fight terrorism

Forcing tech firms to create a "backdoor" to access messages would be a gift to cyber-hackers.

The UK has endured its worst terrorist atrocity since 7 July 2005 and the threat level has been raised to "critical" for the first time in a decade. Though election campaigning has been suspended, the debate over potential new powers has already begun.

Today's Sun reports that the Conservatives will seek to force technology companies to hand over encrypted messages to the police and security services. The new Technical Capability Notices were proposed by Amber Rudd following the Westminster terrorist attack and a month-long consultation closed last week. A Tory minister told the Sun: "We will do this as soon as we can after the election, as long as we get back in. The level of threat clearly proves there is no more time to waste now. The social media companies have been laughing in our faces for too long."

Put that way, the plan sounds reasonable (orders would be approved by the home secretary and a senior judge). But there are irrefutable problems. Encryption means tech firms such as WhatsApp and Apple can't simply "hand over" suspect messages - they can't access them at all. The technology is designed precisely so that conversations are genuinely private (unless a suspect's device is obtained or hacked into). Were companies to create an encryption "backdoor", as the government proposes, they would also create new opportunities for criminals and cyberhackers (as in the case of the recent NHS attack).

Ian Levy, the technical director of the National Cyber Security, told the New Statesman's Will Dunn earlier this year: "Nobody in this organisation or our parent organisation will ever ask for a 'back door' in a large-scale encryption system, because it's dumb."

But there is a more profound problem: once created, a technology cannot be uninvented. Should large tech firms end encryption, terrorists will merely turn to other, lesser-known platforms. The only means of barring UK citizens from using the service would be a Chinese-style "great firewall", cutting Britain off from the rest of the internet. In 2015, before entering the cabinet, Brexit Secretary David Davis warned of ending encryption: "Such a move would have had devastating consequences for all financial transactions and online commerce, not to mention the security of all personal data. Its consequences for the City do not bear thinking about."

Labour's manifesto pledged to "provide our security agencies with the resources and the powers they need to protect our country and keep us all safe." But added: "We will also ensure that such powers do not weaken our individual rights or civil liberties". The Liberal Democrats have vowed to "oppose Conservative attempts to undermine encryption."

But with a large Conservative majority inevitable, according to polls, ministers will be confident of winning parliamentary support for the plan. Only a rebellion led by Davis-esque liberals is likely to stop them.
