# Change in maths A-level specification requires students to buy costly calculators

A change in the A-level maths specification that forces students to fork out an extra £10 for an advanced calculator is a “positive step” for the subject, says Charlie Stripp, director of the National Centre for Excellence in the Teaching of Mathematics.

He said that using these calculators “massively outweighs the increase in cost” and that the use of more advanced technology at A-level was a “step towards real-world maths”.

New standards for the A-level set out by the Department for Education (DfE) require calculators to include an “iterative function” with the ability to compute summary statistics and “access probabilities from standard statistical distributions”.

These features are not available on the calculators typically found in schools, such as the Casio FX83GT Plus, which retails at £7.99. Advanced calculators such as the Casio FX991ES Plus that can carry out these functions retail at £17.99.

A DfE spokesperson said the A-level content advisory board, which assisted the government on the qualification’s reform, recommended the change.

“The new qualifications are intended to ensure that students develop the skills needed for progression to university and employment.”

It is believed the specification change was needed because exam candidates will no longer be given tables of values for statistical distributions.

John Jackson, a former maths teacher in London, warned the cost implications could disadvantage students from low income backgrounds.

“The change means many students and schools will have to purchase new calculators for no great improvement in learning.”

But Stripp said it was a “red herring” to talk about the added cost because “in the real world” maths used advanced technology “all the time”.

“The subject is greatly enhanced by the use of technology and technology needs to be embedded in how it is taught,” he said. “To not make technological requirements on the maths A-level would make it eventually become irrelevant. It would be in the dark ages.

“I see it as only a very positive thing [the upgrade in technology] because being able to use maths in a technological context and being fluent with using technology and maths together to solve problems is what we want people going into technical fields to be able to do.”

He added: “In the overall scheme of things that extra cost is not relevant when you compare the advantages of actually embedding technology properly into the way students are learning maths and their experience of using maths being driven by technology.

“I don’t think it is disadvantaging poor students. We are talking about tens of pounds rather than hundreds or thousands. It is a step in the right direction.”

I’m going to sound a bit of a Luddite here but statistical tables are actually much faster than most calculators. My Texas graphic require me to scroll through a few screen to choose the particular distribution before I can get into the details.

Now Excel, GeoGebra and Wolfram Alpha are much faster than tables and in reality we should be devising systems that are able to use that kind of technology. These types of calculators are actually nowhere near as useful as they claim.

When is that last time anyone use a graphic calculator to draw a graph when they could use GeoGebra or Autograph instead? I’ve needed to get batteries for my graphic for about 6 months now…

It’s not the Casio FX991ES. That is the current model that doesn’t do all of the required functions. The new Casio is the FX991EX which is available later this term. There is also the Texas TI-30X Pro.

‘Costly’ seems a tad sensationalist.

A £20 investment in a calculator pales into insignificance when compared to the average phone contract, pair of designer sneakers or annual school field trip.
