第19题： 第二篇 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 --grade school children as a group don't care much for, or excel(擅长) at, mathematics. So it's heartening to learn that a new kind of 66classroom of the future" shows promise at easing some of these problems, starting with that fundamental piece of classroom furniture: the desk. A UK study involving roughly 400 students, mostly aged 8-10 years, and a new

generation of multi-touch, multi-user, computerized desktop surfaces is showing that over the last three years the technology has appreciably boosted students'math

skills compared to peers learning the same material via the conventional paper-and-pencil method. How? Through collaboration, mostly, as well as by giv- ing teachers better tools by which to micromariage individual students who need some extra

instruction while allowing the rest of the clas.s to continue moving forward.

Traditional instruction still shows respectable efficacy(效力) at increasing

students' fluency iri mathematics, essentially through memorization and practice-

dull, repetitive practice. But the re- searchers have concluded that these new touch screen desks boost both fluency and flexibility--- the critical thinking skills that allow students to solve complex problems not simply through knowing for- mulas and devices, but by being able to figure out what there all problem is and the most effective means of stripping it down and solving it. one reason for this, the

researchers 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 engaging with the problem as part of a group. knowri as synergy Net, the softwarc uses computer vision systems that see in the infrared(红外线的)
