weebecka:So you feel that the heart of a mathematics education should be about the acquisition of the fundamental axioms of mathematics and that is students acquire these they will then be able to mathematise the world. Where have I said 'the fundamental axioms of mathematics'? I'd just expect as a minimum that students should be able to count, add, subtract, multiply and divide before they apply such concepts to real life problems. As Betamale describes, many teachers are still trying to get 16 year old students to be able to calculate basic products of numbers because they've been taught through a subjective philosophy from primary school. weebecka:You believe that mathematics is an objective philosophy. It exists, out there in the world. The rules of mathematics are fixed and unchanging. We learn them, we use them, that's it?
Now you're misquoting me. Objectivism for me is that idea that within the philsophy that is Mathematics, you are right, or you are wrong. Obviously statistics is a caveat to this, but then again the calculations in statistics are either one way or another and it's the interpretation that is subjective. If you take the approach that you, and bgy1mm, and others on here take, then you lose the objectivity - i.e. the all encompassing idea that a mathematical theory is only useful if proven - and Mathematics itself is just another subjective philosophy. The pride people have in Mathematics - and the pride all the great mathematicians have had in their career (right from Pythagoras, through Al-Kwarizmi, Fibonacci, Newton, and so on) is that Mathematics is THE objective philosophy. Lose that, and we might as well stop, now. weebecka:If so could you tell me a bit about your experiences of working with students on rich and extended investigations (or any work where they've had plenty of opportunity and encouragement to go beyond the syllabus) - have you found that they way students have learned through these activities has backed up your view?
I've actually done a lot of work in this area. During my two periods at university I worked with school groups in investigating the structure of bridges, and investigating and developing principles that determined which designs would take the strongest loads; in another session with a different school I led a project investigating the mechanics of bungee jumps, and how to design the rope structures to have the most 'thrilling' bungee jump without damaging the body; In my time as a teacher I've used the Bowland Mathematics materials to investigate the reduction of Road Traffic Accidents in a town; developing a new Smoothie drink for the health food market; that just touches the surface. Whilst these were all fun, and the students learned a lot in applying their knowledge of Mathematics - the one thing that stood out is that whilst students had sound ideas, they did not have the concrete Mathematics (in whatever form: arithmetic, algebra, geometry...) to execute them. In any field, ideas are all well and good - but if you don't have the concrete tools to develop, formalise and execute them, then they're useless. And to quote a great man 'Nothing useless can be truly beautiful'.
