I did one of these a few years ago, and I thought it might be interesting to fire it up again. Relevant details. - I teach mainly secondary school children (11 - 16) though I have taught primary and sixth form in the past. - I teach mainly maths but I've taught other subjects (mainly science) from time to time. - I teach in the UK, and I only know what I've read about education elsewhere. - I work in a 4-19 age range school. Any other teachers feel free to chime in.
