填空题

All over the world, your chances of success in school and life depend more on your family circumstances than on any other factor. By age three, kids with professional parents are already a full year ahead of their poorer peers. They know twice as many words and score 40 points higher on IQ tests. By age 10, the gap is three years. By then, some poor children have not mastered basic reading and math skills, and many never will. this is the age at which failure starts to become unchangeable.
A few school systems seem to have figured out how to erase these gaps. Finland ensures that every child completes basic education and meets a rigorous standard. In the United States, KIPP charter schools enroll students from the poorest families and ensure that almost every one of them graduates high school--80 percent make it to college.
These success stories offer lessons for the rest of us. First, get children into school early. High- quality preschooling does more for a child’s chances in school and life than any other educational intervention.
Second, recognize that the average kid spends about half his waking hours up until the age of 18 outside of school---don’t ignore that time. KIPP students spend 60 percent more time in school than the average American student. They arrive earlier, leave later, attend more regularly, and even go to school every other Saturday.
Third, pour lots of effort into training teachers. Studies in the United States have shown that kids with the most effective teachers learn three times as much as those with the least effective. Systems such as Singapore’s are choosy about recruiting; they invest in training and continuing education; they evaluate teachers regularly; and they award bonuses only to the top performers.
Finally, recognize the value of individualized attention. In Finland, kids who start to struggle receive one-on-one support from their teachers. Roughly one in three Finnish students also gets extra help from a tutor each year. If we can learn the lesson of what works, we can build on it.

Among the educational interventions, the most effective one for the chances of a child in school and life is().
