问题 Students Learn Better with Touchscreen Desks
Observe the criticisms of nearly any major public education system in the world, and a few of the many complaints are more or less universal. Technology moves faster than the education system. Teachers must teach at the pace of the slowest student rather than the fastest. And — particularly in the United States — school children as a group don’t care much for, or excel (擅长）at，mathematics. So its heartening to learn that a new kind of “classroom of the future” shows promise at easing some of these problems, starting with that fundamental piece of classroom furniture： the desk.
AUK study involving highly 400 students, mostly aged 8-10 years, and a new generation of multi-user, computerized desktop surfaces is showing that over the last three years .Technology has appreciably boosted students，math skills compared with peers material via the conventional paper-and-pencil method. How?Through collaboration, mostly, as well as by giving teachers better tools by which to micromanage individual students who need some extra instruction while allowing the rest of the class to continue moviing forward.
Traditional instruction still shows respectable efficacy (效力）at increasing students’ fluency in mathematics, essentially through memorization and practice — dull , repetitive practice. But the researchers nave concluded that these new touchscreen desks boost both fluency ana flexibility — the critical thinking skills that allow students to solve complex problems not simply through knowing formulas and devices, but by being able to figure out what the real problem is and the most effective means of stripping it down and solving it.
One reason for this, the erarchers say, is the multi-touch aspect of the technology. Students working in the next-gen classroom can work together at the same tabletop , each of them contributing and engagiing with the problem as part of a group. Known as SynergyNet, the software uses computer vision systems that see in the infrared (红外线的）spectrum to distinguish between different touches on different parts of the surface，allowing students to access and use tools on the screen, move objects and visual aids around on their desktops, and otherwise physically interact with the numbers and information on their screens. By useing these screens collaboratively, the researchers say, the students are to some extent teaching as those with a stronger grasp on difficult concepts pulll other students forward along with them.
What is the benefit students get from the new tech?
选项 A It makes them more fluent in public speech.
B It offers them more flexibility in choosing courses.
C It is effective in helping them solve physical problems.
D It enables them to develop critical thinking ability.
答案D
解析文中第三段提到研究者总结出这些触摸屏课桌能促进学生用批判性思维来解决复杂的问题，能够找到真正的问题所在，以及最有效的解决方法，而不是简单地通过了解公式来解答。所以答案是D。
