If we really cared, we could increase the quality of teaching beyond all recognition. It wouldn't be remotely difficult. Massively increase pay for teachers, tripling or quadrupling pay at every level. Mandate a specific postgraduate qualification and a statutory minimum of continuing professional development. Recruit only the best and the brightest, specifically seeking out graduates from the best universities. Adve…
We don't revolutionize teaching because TENURE AND SENIORITY RULES ARE LOCKED DOWN BY THE UNIONS. Want to revolutionize teaching (and save some money)? Break the unions and fire the worst 10% of the teaching staff. Then do it again next year. (Edit: we really DO care about teaching, and spend enormous amounts of tax payers dollars and collective worry on it.)

"In 1999, for example, our schools hired 232,000 teachers who had not been teaching the year before (i.e., new teachers hired who were not simply moving from one school to another). But the schools lost more than 287,000 teachers who left for other occupations that year—55,000 more than they hired"
If we have/discover the ability to tell the good teachers from the bad, then we should just start hiring only the good teachers. Eventually the good will out number the bad and maybe even teach the bad teachers a thing or two)
Maybe instead of firing the bottom 10%, we should "improve" them. It's either that or replace them. Of course, you could very well be replacing them with someone just as bad or worse.
