Innovation is routine's worst enemy. Innovation comes when the comfort, and therefore stagnation, of ritual is shaken off and shown to be unfit for purpose. I feel that the best way that any kind of 'innovation' promoting culture can be instilled is by recognising that, at times, the thought processes behind sudden, spontaneous teacher-taken decisions (changing lessons plans, responding to a particularly inquisitive child and his or her query) are completely and utterly positive. Institutional dogma, down to the slightest detail, inhibits in teachers a fear of creating too much noise, of acting, of taking a class outside the classroom if the day is nice. I feel genuine progress, and therefore the instilling of a innovation mindset, comes when teachers feel trusted enough to rip up the mark scheme and become human beings.
