Background: I'm teaching mathematics at a high school with emphasis on mathematics and natural sciences. Usually, pupils at our school have to buy a calculator (TI-89) and we work with those during class and sometimes they are allowed to use them for exams too. Recently, it has been proposed to work with tablets instead of conventional calculators. There has been a poll at the most recent meeting of the maths teachers giving the following result:
For the next school year, each maths teacher decides on his own whether his students buy a conventional calculator or a tablet.
I myself think that conventional calculators are a lot easier to use, don't provide too much or too little information (as opposed to e.g. wolframalpha for students at that stage) and also at our local universities' exams, no tablets are allowed but only calculators.
Question: Do you think high school students should have to stick to conventional calculators or what clear advantages are there in switching to tablets instead?
