这是 2015 年联邦政府的一项研究计划，旨在研究多元化对学生学习成绩的影响，由
NAEP 执行。研究数据主要来自该机构的一项八年级数学测验，以及 Common Core 的
blah blah blah。底下是来自该研究报告的 executive summary，里面有些结论符合一
般猜想，有些会让人惊讶。大家自己看。
（文中所谓的 high density 是指黑人比例高的学校，这些学校多在南方与中西部。）
On average, White students attended schools that were 9 percent Black
while Black students attended schools that were 48 percent Black,
indicating a large difference in average Black student density nationally.
When the analysis
examined variation in density by region and locale, the results showed that
schools in the highest density category
(60 percent to 100 percent Black students) were mostly located
in the South and, to a lesser extent, the Midwest
and tended to be in cities. The highest percentage of schools in the lowest
density category were in rural areas.
Analysis of the relationship between the percentage of students in a school
who were Black and achievement showed
the following:
• Achievement for both Black and White students was lower in the
highest Black student density schools than in the lowest density schools.
• However, the achievement gap was not different.
However, when accounting for factors such as student socioeconomic status (
SES) and other student, teacher, and school characteristics, the analysis
found:
• White student achievement in schools with the highest Black student
density did not differ from White student
achievement in schools with the lowest density.
• For Black students overall, and Black males in particular,
achievement was still lower in the highest density schools than in the
lowest density schools.
• The Black–White achievement gap was larger in the highest density
schools than in the lowest density schools.
• Conducting analysis by gender, the Black–White achievement gap was
larger in the highest density schools than in the lowest density schools for
males but not for females.
In addition, the size of the achievement gaps within each category of Black
student density was smaller when the analysis accounted for student SES and
other student, teacher, and school characteristics (except in the highest
density category), suggesting that these factors explained a considerable
portion of the observed achievement gap.2 | f**********n

黑人与白人学生的成绩，在黑人比例高的学校比较差。但是黑白成绩差异在两者学校没
有差别。
白人在黑人多的学校的成绩，与在黑人少的学校的成绩是一样的。
黑人，尤其男性，在黑人多的学校的成绩低于在黑人少的学校。
黑白成绩差异在黑人多的学校差异程度比较高。
以性别而言，黑人多的学校的男性黑白成绩差异比较高。女性没有差别。
黑白学习成绩差异与黑人多少的关系，低于与其他因素的关系，如社会经济地位或其他
学校属性。
以上是结论，报告也做了原因的分析，他们认为有六个原因导致这些差异：社会经济地
位、老师素质、大人对学生的期待等等。
