American education system won't improve until American kids get off their asses and study hard.
All these movies and articles about fighting w/ teachers unions aren't the real issue. Many of those "bad" teachers would be more motivated if they didn't have to babysit lazy brats all day and if they earned a decent wage.
Charter schools mostly work because they siphon off the most motivated kids and teachers. I am skeptical that they help the system as a whole. Maybe they raise test scores but mostly by helping the most enthusiastic kids get higher scores, not helping the average non-charter kid get higher scores.
btw, i am an american who has spent 6 years living in both(South Asia and East Asia), where kids do get off their asses and they don't have complex charter/teacher motivation/reorganization schemes. Why do kids study so hard there? Because there parents beat it into their skulls that they will be dirt-poor farmers unless they get an education.
