Article: Imagine a classroom missing the one thing that's long been considered a necessary part to reading and writing---paper. No notebooks, no textbooks, no test papers. Nor are there any pencils or pens, which always seems to _ . A "paperless classroom" is what more and more schools are trying to achieve . Students don't do any handwriting in this class . Instead , they use palm size , or specially--designed computers. The teacher downloads texts from Internet libraries and sends them to every student's personal computer. Having computers also means that students use the Web. They can look up information on any subject they're studying from maths to social science. High school teacher Judy Herrell in Florida, US, described how her class used the Web to learn about the war in Afghanistan over one year ago. We could touch every side of the country through different sites from the forest to refugee camps, she said ."Using a book that's three or four years old is impossible."And exams can go on line too. At a high school in Tennessee, US, students take tests on their own computers. The teacher records the grades on the network for everyone to see and then copies them to his own electronic grade book. A paperless classroom is a big step towards reducing the waste of paper. High school teacher Stephanie--Sorrell in Kentucky,US, said she used to give about 900 pieces of paper each week to each student. "Think about the money and trees we could save with the computers,"she said .But, with all this technology, there is always the risk that the machines will break down. So , in case of a power failure or technical problems, paper textbooks are still widely available for these hi--tech students.
