i disagree. i think most people who become teachers do it for the love of teaching and low pay is a burden they are willing to suffer with. i think if it was a high paying job then more people who did not enjoy teaching or children would seek it out. having said that i think teachers should be paid more but based on performance like all other jobs and omg we should be able to fire the freaks that teach because it gives them helpless people to abuse.
Unfortunately, people who enter teaching wanting to teach, and willing to take the low pay, find after a few years they just can't make the sacrifice to their family that is required. Some, like myself and my sister, are fortunate to have spouses who earn good salaries and can compensate--but others are not so lucky. It is almost impossible to accept a salary 1/3 of what your math/science skills can command in the private sector, for example.
For some reason, the people who believe in the market economy do not entirely support it for teachers. If they cannot find enough math/science graduates, for example, they accept less qualified candidates and say simply that is good enough.
Would Boeing, or Microsoft accept employees who did not have a minimum of those skills?
Yes, teachers have some time off in the summer, but it is not a full three months vacation as it once was. Most of us prepare lessons and are required to take courses--or want to take them--during that time.
As for performance pay, most teachers are against it because as it stands, the latest "bonus" pay is given to teachers whose students achieve grade level competence based on standardized tests.
This means that if you get a student two years behind "grade level" and you are able to bring them to close to grade level but not entirely, you get...nothing. That's right, two years of progress crammed into a year, and you still get...nothing. Meanwhile, the teacher next door who works half as hard makes the same salary you do.
I don't have all the answers, but I can tell you that low pay is a huge factor here.
Again, as an economics major, I can tell you--if you aren't getting qualified candidates, you aren't paying enough. It's the old supply/demand curve.
Substitutes are a perfect example of this. We don't pay them enough to make an actual living at their job, we expect them to walk into a classroom and teach just like the regular teacher would, and we are frustrated and amazed when it becomes obvious they are either incompetent or "just waiting for their real job."
