Since 20

4、03 the school has boosted the proportion of so-called under-represented minority students (blacks, Latinos (南美洲人 ), and Native Americans, about 30 percent of the U.S. population) in entering freshman classes from 8 percent to 13 percent. But Bowdoin has not done quite as well when it comes to actual

5、ly graduating minorities. While nine out of 10 white students routinely get their diplomas within six years, only seven out of 10 black students made it to graduation day in several recent classes. The United States once had the highest graduation rate of any nation. Now it stands 10th. For the firs

6、t time in American history, there is the risk that the rising generation will be less well educated than the previous one. The graduation rate among 25-to 34-year-olds is no better than the rate for the 55-to 64-year-olds who were going to college more than 30 years ago. Studies show that more and m

7、ore poor and nonwhite students are eager to graduate from college-but their graduation rates fall far short of their dreams. The graduation rates for blacks, Latinos, and Native Americans lag far behind the graduation rates for whites and Asians. As the minority population grows in the United States

8、, low college-graduation rates become a threat to national prosperity. The problem is noticeable at public universities. In 2007, the University of Wisconsin-Madison-one of the top five or so “public Ivies“-graduated 81 percent of its white students within six years, but only 56 percent of its black

9、s. At less-selective state schools, the numbers get worse. Community colleges have low graduation rates generally-but rock-bottom rates for minorities. A recent review of California community colleges found that while a third of the Asian students picked up their degrees, only 15 percent of African-

10、Americans did so as well. Private colleges and universities generally do better, partly because they offer smaller classes and more personal attention. But when it comes to a significant graduation gap, Bowdoin has company. Nearby Colby College logged an 18-point difference between white and black g

11、raduates in 2007 and 25 points in 2006. “Higher education has been able to get around this issue for years, particularly the more selective schools, by saying the responsibility is on the individual student,“ says Pennington of the Gates Foundation. “If they fail, its their fault.“ Some critics blam

12、e affirmative action-students admitted with lower test scores and grades from shaky high schools often struggle at top schools. But a bigger problem may be that poor high schools often send their students to colleges for which they are “undermatched“: they could get into better, richer schools, but

13、instead go to community colleges and low-rated state schools that lack the resources to help them. Some schools out for profit cynically increase tuitions and count on student loans and federal aid to foot the bill-knowing full well that the students wont make it. “Colleges know that a lot of kids t

14、hey take will end up in remedial classes, for which theyll get no college credit and then theyll be dismissed,“ says Amy Wilkins of the Education Trust. “The school gets to keep the money, but the kid leaves with loads of debt and no degree and no ability to get a better job. Colleges are not holdin

15、g up their end.“ A college education is getting ever more expensive. Since 1982 tuitions have been rising at roughly twice the rate of inflation. University administrators insist that most of those bikes are matched by increased scholarship grants or loans, but the recession has decreased private en

16、dowments(捐助 ) and cut into state spending on higher education. In 2008 the net cost of attending a four-year public university equaled 28 percent of median family income, while a four-year private university cost 76 percent of median family income. More and more scholarships are based on scores, not

17、 need. Poorer students are not always the best-informed consumers. Often they end up deeply in debt or simply unable to pay after a year or two and must drop out. There once was a time when universities took an unreasonable pride in their drop-out rates. Professors would begin the year by saying, “L

18、ook to the right and look to the left. One of you is not going to be here by the end of the year.“ But such a Darwinian spirit is beginning to give way as at least a few colleges face up to the graduation gap. At the University of Wisconsin-Madison, the gap has been roughly halved over the last thre

19、e years. The university has poured resources into peer counseling to help students from inner-city schools adjust to the faster pace of a university classroom, and also to help minority students overcome the stereotype that they are less qualified. State and federal governments could sharpen that fo

20、cus everywhere by broadly publishing minority graduation rates. For years private colleges such as Princeton and MIT have had success bringing minorities onto campus in the summer before freshman year to give them a head start on college-level courses. The newer trend is to start recruiting poor and

21、 nonwhite students as early as the seventh grade, using new tools like hip-hop competitions to identify kids with sophisticated verbal(语言的 ) means. Such programs can be expensive, of course, but cheap compared with the millions already invested in scholarships and grants for kids who have little cha

22、nce to graduate without special support. With effort and money, the graduation gap can be closed. Washington and Lee is a small, selective school in Virginia. Its student body is less than 5 percent black and less than 2 percent Latino. While the school usually graduated about 90 percent of its whit

23、es, the graduation rate of its blacks and Latinos had dipped to 63 percent by 2007. “We went through a dramatic shift,“ says Dawn Watkins, the vice president for student affairs. The school aggressively pushed mentoring (师徒制 ) of minorities by other students and “partnering“ with parents at a specia

24、l pre-enrollment session. The school had its first-ever black homecoming. Last spring the school graduated the same proportion of minorities as it did whites. If the United States wants to keep up in the global economic race, it will have to pay systematic attention to graduating minorities, not jus
