The issue is that Americans as a whole have to start viewing education more seriously and learning needs to be put back on the student. In places in Japan and India, students are held accountable for their grades. There's no blaming of teachers and their parents do not accept anything below a A. I can't tell you how many times I've had students who didn't do homework, absent at least once a week got an F and then their parents come to me whining about their child failing.
Secondly, teachers should have more qualifications and it should be treated like the medical field . In Finland teaches need to have a masters degree to teach. This ensures that the teacher is highly qualified and is able to give his or her students a quality education.
Japan weeds out under performers in stages. Use public schools to educate the less academically inclined. Charters for those who can go on to college or specialized trade schools.
There are poor teachers just as there are poor students, they should be weeded out as well. In the private school I am most knowledgeable about, half the teacher did not have teaching degrees. A high achieving school though.
We don't hold adults accountable for much, start with the kids and have consequences for actions/inactions. Most successful schools have motivated parents.
So, this leads us back to, why are you supporting the status quo that will not and cannot yield the results you want?
