Terrible idea. (I am a former school teacher, btw.)
The ideal motivator for kids should be: "A good education will enrich you and lead to a better life."
The not-so-ideal motivator that I am willing to settle for is: "If you don't go to school, you'll get arested for truency and sent to reform school."
But bribing kids??? It ruins everything education is suppsed to be. I don't mind parents bribing their kids, but no way should the government do it.
Another motivator that I haven't mentioned is that of relationship. If kids have meaningful relationships at school with either peers or teachers or both, they will WANT to go every day of the week, twice on Sundays, and all through the summer. But if they are AFRAID of school, feel alienated by it, victimized, even traumatized by it, they will do their best to avoid going, and when they are there they will be emotionally shut down and on the defensive. That's not an environment for learning, and certainly not one for healthy relationships.
So my ultimate soapbox is: smaller schools, smaller classes, more generous student-teacher ratios. Kids will feel safer with the increased presence of adult supervision, they behave better, and the bullies will be given less opportunity to BE bullies. The whole educational system will feel less like a giant machine that those poor kids need to navigate with their lives in their hands. The school buildings I propose will not be fortified fortresses full of armed police officers, metal detectors, and drug-sniffing dogs. In my vision for schools, each school will feel more like a small intimate community where everyone knows each other, kids have actual names and not numbers, and the constant fear kids of today have of each other will be non-existent.
Too much money to do it my way??? Well, how the hell much money does it cost to have three dozen security cameras running all the time, two cops on duty all day, a K-9 unit on standby, and two metal detectors at every entrance? And is THAT really an environment we want our kids in? Some might protest: "Yeah, but it's more cost-effective to have huge schools with security access and more kids per teacher per classroom." To that I say #1) Dammit, these are our kids, they are worth every penny, and #2) How many US governors, senators, and congressmen won't send their kids to a pubicc school? and why is that?
