Parents who have books in the home increase the level of education their children will attain(获得), whether rich or poor, according to a 20-year study led by Mariah Evans.
For years, educators have thought the strongest predictor(预示物) of attaining high levels of education was having parents who were highly educated. But, the study showed that the difference between being raised in a bookless home compared to being raised in a home with a 500-book library has as great an effect on the level of education a child will attain as the difference between having parents who are barely literate (有文化的) and having parents who have a university education.
Being a sociologist, Evans was particularly interested to find that children of less-educated parents benefit the most from having books in the home. What kinds of investments should we make to help these kids get ahead? The results of this study indicate that getting some books into their homes is an inexpensive way that we can help these children succeed. Evans said, "Even a little bit goes a long way. Having as few as 20 books in the home still has a significant impact on motivating a child to a higher level of education, and the more books you add, the greater benefit the children get."
The researchers were struck by the strong effect having books in the home had on children's educational attainment even above and beyond such factors as education level of the parents, the father's occupation or the economic level of the country.
Having books in the home is twice as important as the father's education level, and more important than whether a child was brought up in a developing country or a developed country. Surprisingly, the difference in educational attainment for children born in a developed country and children born in a developing country was just 2 years, less than two-thirds of the effect that having 500 or more books in the home had on children.
