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一particularly in the United States一
school children as a group don't care much for,or excel（擅长）at,mathemnatics. So it's 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.
A UK study involving roughly 400 students,mostly aged 8一10 years,and a new generation of
multis-touch,multi-user,computerized desktop surfaces is showing that over the last three years the technology
has appreciably boosted students'math skills compared with peers learning the same material via the con-
ventional 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 moving forward.
Traditional instruction still shows respectable efficacy（效力）at increasing students'fluency in mathe-
matics,essentially through memorization and practice一dull,repetitive practice.But the researchers have con-
cluded that these new touchscreen desks boost both fluency and flexibility一the critical thinking skills that al-
low 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 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.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 desk-
tops,and otherwise physically interact with the numbers and information on their screens.By using these
screens collaboratively,the researchers say,the students are to some extent teaching themselves as those with
a stronger grasp on difficult concepts pull other students forward along with them.

选项 How does the new tech work to improve students'mathematical learning? A:It helps fast learners to learn faster. B:It enables them to work together. C:It makes teachers'instruction unnecessary. D:It allows the whole class to learn at the same pace.

答案 B

解析由第一段第三句可知D项说反了，实际上公共教育系统下，老师的教学进度是适应学得最慢的学生的。
由第二段最后一句“...giving teachers better tools by which to micromanage individual students who need some extra instruction while allowing the rest of the class to continue moving for- ward.（······给予老师更好的工具，老师们可以利用这些工具对需要额外指导的学生进行微观处理，而班上的其他同学可以继续向前学。）”可知答案，C项是该含义的同义表述。mi- cromanage意为“微观处理，微观管理”。
由第三段第二句话“...these new touchscreen desks boost both fluency and flexibility一the critical thinking skills that allow...（这些新的触屏桌面提高了流畅性和灵活性——允许学生······的批判性思维技巧）”可知答案。
由最后一段第二句“ Students working in the next-gen classroom can work together at the same tabletop（下一代的课堂中，学生们可以通过同一个桌面一起学习）”可排除A项。由最后一段第三句“Known as SynergyNet , the software uses computer vision systems that see in the infra-red spectrum to distinguish between different touches on different parts of the surface,allowing students to access and use tools on the screen...（名为‘协同网络’的软件利用能在红外光谱中观察的计算机视觉系统来区别表面不同部分的不同触摸，允许学生们访问和使用屏幕上的工具······）”可知，该软件并不能自动识别不同的使用者，而是借助于计算机视觉系统，故排除C; 文中只是说学生可以使用屏幕上的工具，并没说是不同的工具，故排除D。所以选B，这也可通过结合第三段第二句“…these new touchscreen desks boost both fluency and flexibility一thecritical thinking skills that allow…（这些新的触屏桌面提高了流畅性和灵活性——允许学生······的批判性思维技巧）”和第四段第一句“One reason for this, the researchers say, is themulti-touch aspect of the technology.（其中一个原因，研究者称，就是该技术的多点可触性。）”得出。
由最后一段第二句“Students working in the next-gen classroom can work together at thesame tabletop（下一代的课堂中，学生们可以通过同一个桌面一起学习）”可知答案。
