In the United States, experts are calling for major changes to the admission process in higher education.
The National Center for Educational Statistics (or NCES) reported that U.S colleges and universities received more than million applications between 2013 and 2014 and admitted more than 5 million students. But the problem is not in the number of students, a new report says. The report is called ''Turning the Tide-Making Caring Common. ''
The report argues that the process schools use to choose students causes major problems. David Hawkins is the Executive Director for Educational Content and Policy. He says that most colleges and universities require many things from students when they apply.
Schools usually require an essay describing a student's interests or why they want to study at that school. The schools also ask for letters from teachers describing why a student is a good candidate. But, Hawkins says, schools are most concerned with a student's high school grades and standardized test results.
The Education Conservancy is an organization that fights to make higher education equal and available. Lloyd Thacker is the Executive Director of the Education Conservancy, saying that the college admission process has changed a lot.
''Over the past 30 years, college admissions have become more complex. '' He says that ranking systems for colleges and universities are a big part of the problem.
U.S. News and World Report is a media company that creates a list of what it calls ''America's Best Colleges''. The company bases the list on information collected from colleges and universities across the country. This information includes results of standardized tests like the SAT from all of a school's students. Higher average test results help put schools higher on the list.
Thacker claims, ''Too many students are learning to do whatever it takes in order to get ahead, even if that means sacrificing their own individuality, their health, their happiness and behavior…''
''The impact on students and on parents is that college is all about where you go. The rank has nothing to do with the quality of education that goes on at the college''.
The Harvard report states that the best way to change the admission process is by changing college applications.

Many electronic parts are made of hard materials that break easily. That makes them tough to use in products that need to bend. Now, Sam Yoon and his team have developed a thin mesh (网状物) that can both bend and conduct electricity.
His team started out with something called acrylonitrile, a clear liquid often used to make thin plastic fibers. Yoon and his team mixed this material with another liquid, which acted as a solvent. A solvent is something that can make other substances into liquids. Then, they squeezed the mix through a very tiny pipe: As the mixture was sprayed through the air, the solvent evaporated(挥发)and the acrylonitrile molecules linked up to make long chains, creating a type of plastic known as PAN. The researchers continually squeezed the mixture through the pipe. A single long PAN fiber was created. The scientists moved the pipe back and forth as the PAN was squeezed out. It ended up creating a layer that looked something like a spider’s web.
PAN, like most plastics, doesn’t conduct electricity. So the team’s next step would normally be to add a coating of metal so that electricity could flow through it. But it could be tough sticking such coatings on PAN. So the researchers added an extra step. They sprayed a thin coating of an inert metal onto the PAN. Inert metals, like gold, typically don’t react with other materials. The researchers then added another layer of PAN fiber at the top of the first, web-like layer. They provide temporary support, helping the metal-sprayed base resist sinking during the next step.
The researchers connected the fiber-covered frame to a negatively changed electrode. Then they dipped the fiber-covered frame into a solution that included the liquid copper. The team turned on the electric current for about one minute to make it run through the solution. The copper in the solution was attached to all of the fibers. But it stuck only to those that wore a metal jacket. Besides adding a thin layer of copper that conducts electricity, this process helped bond the PAN strands together at places, where they touched each other, Yoon notes.
The researchers then attached all of the fibers to a thin, clear layer of plastic, which had sticky backing, like a Band-Aid. Finally, the team dipped all of these into a liquid that made any of the PAN fibers that lacked a copper jacket into liquids. Only those that can be used to conduct electricity were left. Because the fibers were very thin and widely separated, light waves easily travel through the mesh. The copper coating acted just like a wire, permitting electricity to flow freely across it.
1.The team used another liquid in the process to .
A.make acrylonitrile evaporate B.turn acrylonitrile into plastic fibers
C.make acrylonitrile conduct electricity D.conduct electricity instead of acrylonitrile
2.What should the team do first when using PAN?
A.Make it easy to break. B.Make it react with other materials.
C.Make it conduct electricity. D.Find a way to make it into a liquid.
3.What does the underlined word those in the last paragraph refer to?
A.The thin plastics. B.Just the copper coatings.
C.All the PAN fibers. D.All the copper-coated fibers.
3D TV, Without the Glasses
If you’re thinking about buying a 3D TV, you might want to wait a while. Researchers have developed new 3D technology that doesn’t need any special glasses to work its magic. The new technology could advance the development of 3D on mobile devices, too.
Bioethics Panel Gives Yellow Light to Anthrax Vaccine Trial in Children
A U.S. bioethics committee has said that the country may consider testing the anthrax vaccine in children. The panel advises that the vaccine be tested in progressively younger age groups and includes the caveat(警告) that testing should only take place if risks are “minimal.”
Evolution via Roadkill
We usually think of evolution happening over thousands or millions of years, but it can be surprisingly speedy-literally. In just 3 decades, highway-dwelling swallows(燕子)have evolved shorter wingspans(翼展) to better dodge oncoming cars.
Patients Should Get DNA Information, Report Recommends
Would you want to know if you were at risk for cancer? What about a fatal heart condition? A group of genetics experts, along with the influential American College of Medical Genetics and Genomics, have recommended that anyone whose genome is sequenced for any medical reason must be told about their genetic susceptibility to serious health problems, regardless of whether they want to know.
Congress Completes Work on 2013 Spending Bill
This week, the U.S. Congress passed a bill to fund the government until the end of the fiscal(财政的) year, and research agencies now know how much to spend in 2013. The so-called continuing resolution retains the sequester and its $85 billion cut in discretionary spending. The bill throws NASA’s planetary programs a lifeline and gives the National Science Foundation a bit of a boost, but the National Institutes of Health’s funding stays flat at 2012 levels-bad news for biomedical research.
Making Moonshine Safe to Drink
Home-brew drinkers in developing countries often risk blindness or even death from methanol poisoning when they drink. Now, scientists have made a reusable wireless chip that can analyze a drink’s methanol content and warn users of any danger. In 2 years, they hope to develop a product that can send results directly to a cell phone.
