It's really obvious, and I'm sure most people expect me already knew about it. But it is the one thing that would have been useful to me all my life, had I been taught it in school.<br /><br />(The Test of Reasonableness is simply about doing a rough estimate of what something should be. E.g. I'm so hopeless at mental arithmetic that 22 x14 is hard for me. But I can work about 20 x 14, so I know that the answer must be in the region of a bit more than 270).Flora Marriotthttp://floraworks.menoreply@blogger.comtag:blogger.com,1999:blog-21077063.post-36372248523587502592012-10-12T10:01:45.236+00:002012-10-12T10:01:45.236+00:00very good postvery good postgutscheine zum ausdruckenhttp://gutscheinezumausdrucken.org/noreply@blogger.comtag:blogger.com,1999:blog-21077063.post-19509943995403458062012-10-11T14:15:49.300+00:002012-10-11T14:15:49.300+00:00I would probably agree with Roger Schank.

Time to bring it back methinks. Interestingly, Wolfram also uses your car analogy in his TED talk. It's high time someone 'did the maths' and realised that most of what is taught in maths is not used in the majority of jobs.Donald Clarkhttps://www.blogger.com/profile/00796341486328270474noreply@blogger.comtag:blogger.com,1999:blog-21077063.post-84990546345837308372012-10-10T07:49:18.882+00:002012-10-10T07:49:18.882+00:00I can only agree!

Adding, subtracting, multiplying, dividing, percentages... in other words, all the practical 'maths' required to function in the modern world.<br /><br />The abstract qualities of pure maths are beyond most learners simply because they are taught in the abstract: a+b=c-(x+y) =>WTF!?! As you say, teach them interesting and relevant things like programming... and show them how to find the maths skills they may need to complete their work. Quite apart from anything else, this is much more like <i>real world</i> skills that I use every day.<br /><br />I love the justification that "learners need to know these things in case their calculators stop working"... one may as well teach them how the internal combustion engine works in case their car runs out of petrol. Pointless.<br /><br />Thanks for the brain food!N Wintonhttps://www.blogger.com/profile/11725138089778173154noreply@blogger.com
