The problem is that the government need to actually allow teachers to teach.
But you also have to have methods of properly monitoring teachers to ensure the crap ones are properly dealt with. It was failure to do that which led to where we are today with over-zealous monitoring.
We all remember our school days where there were lazy teachers who basically did bugger all, or weak teachers who couldn't get their classes to behave and listen, or incompetents who just couldn't teach.
There's no problem with the majority of genuinely professional teachers who do the job properly behind their closed classroom door. But what about the ones who aren't?
And before you say that things are different now. No, they're really not. My son is coming to the end of his secondary years and we're still seeing the same examples of crap teachers as when I was at school 40 years ago. He's had one year where his Maths teacher never sat a single piece of homework, another year where the Physics teacher never actually did any teaching - he just sat at the front each lesson and told the class to make notes and do the questions out of each chapter of the text book, a History teacher who set a huge project that took weeks but never bothered to mark any of it, the same history teacher a few years later teaching the wrong module in GCSE History.
This is happening in the last few years, during the so-called invasive Ofsted monitoring etc, so it's clearly not working, yet at the same time, the professional teachers are doing all the extra work at the same time as teaching properly! So, new the current supervision and monitoring isn't working, but we do need a way of monitoring and improving the crap teachers - you can't deny that some are still crap - every trade and profession will have some poor staff and every trade/profession has its own ways of monitoring. I wonder how teachers themselves would prefer their profession to be monitored?
