All of these suggestions would cost billions, and have only a moderate impact at best. They are admirable goals, but impractical. These ideas have been batted around for years by politicians and educationalists, and the same stumbling blocks keep being hit upon.
Expand classrooms and hire more janitors/IT people/other support people.
Cost would be a limiting factor, as would how many people it is actually realistic to emply in a given geograhical area. You would have a hard time arguing to a taxpayer that they needed to pay more so a better janitorial service could be provided to a local school.
Institute teaching training programs...
There are already plenty of good teacher training programmes that produce skilled (if inexperienced) teachers - more than can reasonably be emplyed with current budgets. The problem is getting them experience so they become effectve teachers as opposed to just ones with the raw skills.
insure best preforming students have the worst teachers ('cus they would do good anyway) and the worst get the best
That has been shown to at best cause a difference of 1/20th of a grade per pupil.
Wait until a sufficently qualified work force is generated
If in the UK teachers were all required to have a Masters degree (or equivalent), it has been shown that it would "probably" rasie attainment by 1 GCSE grade in 30 (thirty) years - this sort of change happens slowly.
Increase teacher pay to draw smarter people into the profession
Intelligence is not the sole factor in teacher quality - they need personality, humour, humanity, work ethic... and people do things for reasons other than money. More pay would possibly drag people into the profesison you wouldnt want in a classroom. Also, cost. Adding 10% to a teachers pay packet would cost millions.
encourage teachers to go back to work (that may include pension cuts, so they stay in longer). Raise retirment age (something that I should have put in the list o' demands) so that good teachers can stay in the profession for longer
You ever seen a 68 year old trying to work with a class of teenagers? I have, and its not pretty. Older teachers need to be used to train younger ones with the energy and enthusiasm to teach kids.
The trouble is that as everyone has been a school pupil they feel they know how education works. Sorry to say it but most people dont.
