This from Stephen Downes is, for me, a reminder to consider whether any of my stuff might be useful One Laptop Per Child and/or the Commonwealth of Learning.

Monday, April 30th, 2007UK vs Chinese Math Tests
Thursday, April 26th, 2007BBC NEWS reports British chemists as pointing out the difference between an admission test for Chinese science undergrads and a UK university’s diagnostic test for incoming students. But perhaps they are comparing Chinese apples with British oranges (or vice versa?)
After all, in the Chinese question (assuming that by “square prism” they mean “right prism” – which is what it looks like) part (ii) could be on the senior level of our own BC high school math contest (and so could the rest if our high school students had any exposure to vectors), and the UK one could be a soft pitch from our Langara Math Diagnostic Test.

Wednesday, April 25th, 2007squareCircleZ on Biorhythms
Tuesday, April 24th, 2007In squareCircleZ » Trig graphs – how do you feel today?, Murray Bourne at squareCircleZ has a nice Flash gizmo to show biorhythm graphs and links to a site debunking their validity. Actually I think a nice lesson based on this would be to use a similar gizmo to support a demonstration of how sensitive the timing of coincidences between the different cycles is to small perturbations in their frequencies (most of those who experience biological cycles know that they usually aren’t entirely regular!). This might also lead to discussion of other more real biological cycles and periodicities – including nontrig ones like junebug and locust populations – and to the fact that astronomical regularities do have such unearthly precision that they can in fact be followed for many hundreds of cycles to make predictions about coincidences which are actually observed.
