It mentions the use of calculators on mobile phones etc, but I don’t allow their use in maths classes because they give the wrong answer (try on them or on the Windows standard calculator and you’ll see what I mean).
The new A level syllabuses don’t distinguish between scientific and graphical calculators, but both are banned from the first Pure Maths module. It will be fascinating to see how students cope with this.
My Norwegian students all have graphical calculators (mainly Casio which I find difficult to use compared with Texas, though I like Casio’s scientific calculators) and the only way they are able to solve quadratic equations is to use the calculator, even if the quadratic factorises easily.
Other students, being students, don’t always bring calculators even when they need them. So when they have to solve I am very tempted to give them old-fashioned four-figure tables (which you can still buy!) but instead I give them an old scientific calculator. On those, to find , you have to type which so flummoxes them that they don’t forget to bring their own calculator again 😀
