I sat a GCSE in maths 3 years ago (intermediate paper) - the questions were not easy - I can remember some of them looking very similar to the examples given - I hate to say it but not having used algebra since I took the exam I would have to go back and look at a book in order to answer those examples!! <BR />Tracey.Tue, 03 Jun 2008 11:13:36 GMThttps://community.plus.net/t5/General-Chat/GCSE-in-maths-now-easier/m-p/532784#M17035Captainkirk2008-06-03T11:13:36ZRe: GCSE - in maths now easier

It was 1963 for me and although I vaguely recognise the form of the questions I'm not certain if I would know where to start now - and to think I went on to get 'A' Level Maths as well <img class="lia-deferred-image lia-image-emoji" src="https://community.plus.net/html/images/emoticons/embarrassed.gif" alt="Embarrassed" title="Embarrassed" /><BR />CliffTue, 03 Jun 2008 11:28:26 GMThttps://community.plus.net/t5/General-Chat/GCSE-in-maths-now-easier/m-p/532785#M17036Cliff_Jordan2008-06-03T11:28:26ZRe: GCSE - in maths now easier

I will just paste this in from today's Guardian....<BR />Without the big maths stories our numbers are plummeting<BR />Britain has been denied a generation of experts thanks to dumbed-down teaching of what should be a magical subject<BR />Marcus du Sautoy The Guardian, Tuesday June 3 2008<BR /> What is the point of studying mathematics? I have never used a sine or cosine in my everyday life. And solving quadratic equations? Although a footballer subconsciously solves one every time he works out where to stand to volley a free kick, I don't think Wayne Rooney is using the formula he was taught in school to make his decision. So should we be worried by a new report out today claiming that the failure of mathematics education in the UK has lead to the disappearance of half a million mathematicians?<BR />A study published by the thinktank Reform finds that since the 1980s, mathematics has been dumbed down and made so anaemic that students are being put off taking it beyond the compulsory tick in the box at GSCE. City firms have certainly noticed the evidence of a lost tribe. The great majority of the mathematicians they rely on are recruited from overseas. Countries such as China and India have realised the crucial role mathematicians play in the success of their economy and are pumping out fantastically competent mathematicians that increasingly fill the hole left in Britain. The report estimates that the cost to the UK economy since 1990 of not raising homegrown mathematicians totals a staggering £9bn.<BR />Their analysis of exam papers from the 1950s to the present day concludes that the current generation of students are not being stretched mathematically in the same way their predecessors were. An attempt to make the mathematics more "relevant" has ended up just making it boring. The move away from rigour and logic, the bedrock of mathematics, has emasculated the subject. But it is precisely this ability to think logically that employers are so thirsty for. And it is not just the financial sphere that values such skills. Mathematics is much more than an ability to manipulate numbers and perform arithmetic computations. Trigonometry and quadratic equations are important because they teach people an analytic way of thinking that can be applied in all walks of life.<BR />But if we want to ensure we don't lose another generation of mathematicians it must also be an inspiring subject, forming a springboard for the dive into deeper mathematics. We are being too timid in what we are challenging students with. It is like teaching someone to play a musical instrument and only making them play scales and arpeggios, never letting them listen to real music. Even if you can't yet play Bach or the blues, at least you realise what you are aiming for.<BR />In mathematics we are missing telling the kids the big stories of maths. Students should be exposed to the wonders of four-dimensional shapes, the fascination of the primes, the mysteries of topology. One can motivate these as essential tools in modern life: they are key to the way mobile phones change voices into a stream of 0s and 1s, how credit card numbers are kept secure on the internet, how Google works. But they also have an exciting quality in their own right which, regardless of practical applications, can challenge students to see the world in new ways.<BR />It was these big stories that turned me on to mathematics. A teacher at my comprehensive school when I was about 13 recommended a couple of books that explored maths beyond the long division of the classroom.<BR />He pointed me towards Martin Gardner's column in Scientific American, which slipped in fascinating bits of maths on the back of puzzles. I attended the Christmas lectures at the Royal Institution, that year given by Christopher Zeeman, the first time they were ever given on maths. He made it all look so exciting I came away knowing that I wanted to be a mathematician when I grew up.<BR />It is a lack of teachers who can tell the big stories that is part of the problem. But it is one that government is trying to address with the introduction of the National Centre for Excellence in the Teaching of Mathematics, a coordinated attempt to enrich teachers, who can in turn inspire their pupils.<BR />It's not as if mathematics is completely isolated in our society. There seems to be a real thirst recently for things mathematical. Last year Complicite's play A Disappearing Number about mathematics was a sell out at the Barbican in London, won the Olivier best play award and returns for a rerun this autumn. On television, Ridley Scott's Numb3rs does for maths what CSI did for forensic medicine. <BR />Maths even has a starring role in two recent Hollywood movies, 21 and the Oxford Murders, with Kevin Spacey and Elijah Wood showing how maths can be used to break Vegas and crack crimes. And how many people sit down every morning to stimulate their brain cells with the logical challenges of the sudokus that fill our newspapers? Perhaps it is time to find innovative ways to bring this thirst for mathematical stories and games from the adult playground into the classroom and transform mathematics from geek to chic.<BR />· Marcus du Sautoy is professor of mathematics at Wadham College, Oxford and author of Finding Moonshine <BR />Tue, 03 Jun 2008 16:20:10 GMThttps://community.plus.net/t5/General-Chat/GCSE-in-maths-now-easier/m-p/532788#M17039dgdclynx2008-06-03T16:20:10ZRe: GCSE - in maths now easier

I like maths... ironically, I actually got a better mark for it in my A-level than music, despite the fact I took the latter for my degree. Having said that, one of my recent compositions actually used A-level trigonometric transformations, so I've found some way of combining the two. And I do find some of the techniques I learnt in maths useful in everyday life... I'm a very methodical and precise person, which probably means that I'm tempted to calculate things properly when other people would just guess. For example, every so often I find myself needing to use logs - I can't think why now, but I do. They're not an advanced thing at all, but I wonder how many people do actually use things like that outside of the classroom...Tue, 03 Jun 2008 17:38:36 GMThttps://community.plus.net/t5/General-Chat/GCSE-in-maths-now-easier/m-p/532789#M17040Be3G2008-06-03T17:38:36ZRe: GCSE - in maths now easier
