The two authors write, “we demonstrate that in stark contrast to earlier studies, the black-white test score gap among incoming kindergartners disappears when we control for a small number of covariates.” They add, “There is suggestive evidence that differences in school quality may be an important part of the explanation. None of the other hypotheses we test to explain why blacks are losing ground receive any empirical backing.”
两位作者写道,“和早期的研究形成鲜明对比的是,我们的研究证明,当我们对少数协变量进行了控制后,黑人和白人进入幼儿园前的考分差距就消失了,”他们还表示,“这是一个暗示性的证据,显示学校教学质量的差异,可能是导致考分差距形成的重要原因之一。我们也测试了用来解释为什么黑人的成绩每况愈下的其他假设,但它们没有获得任何实证的支持。”
We have to figure out a better way to approach intervention, whether it’s education-based or neighborhood-based or both. Otherwise how can we interrupt the intergenerational transmission of disadvantage we are only beginning to understand?
对于弱势境地代代相传的情况,我们才刚刚开始有所了解;必须找出一个更好的办法,来对此加以干预,无论这个办法是基于教育的,还是基于居民区的,还是双管齐下。否则,我们怎样才能阻止它继续传递下去呢?
