| 1251718 | 2012-01-02 21:05:00 | Yes I will put my hand up and say although I have seen slide rules I don't know how they work, I do know that someone skilled in the use of an abacus can do addition faster than most of us can with a calculator. I do think calculators should not be used for exams though as it proves nothing except that you can push buttons. Fine if you want a job at a nuclear weapons launch site, useless for anything else |

| 1251721 | 2012-01-02 21:47:00 | So much of NCEA is formula/calculator based no. Its almost too easy. There is no knowledge about HOW and WHY everything works. We get told that you do this becase is works. Dont need to know why, all you need to know is that you substitute a with y to work out x. Its sad, my uncle was tutoring me for maths before the exams, the stuff he knows is great but I actually couldn't follow with him because he was describing stuff that we had been taught but I didnt understand it. We got the same answers but he knew what was going on and why. I didn't. About twenty five years ago they asked some teacher trainees these algebra questions they had asked some twelve year olds back in about 1910 and guess which group did the best. That's right the twelve year olds. |

| 1251723 | 2012-01-03 03:47:00 | I still have my sliderule somewhere around - it's a circular one. I used to love logarithm work, but sadly think I chucked the book out some years ago... |
