Schmidt of Michigan State University, who led the new analysis, "no single intellectually coherent vision dominates U.S. educational practice in math or science.” The reason, he said, "is because the system is deeply and fundamentally flawed."The new analysis, released this week by the National Science Foundation in Arlington, Va., is based on data collected from about 50 nations as part of the Third International Mathematics and Science Study.Not only do approaches to teaching science and math vary among individual U.S. communities, the report finds, but there appears to be little strategic focus within a school district's curricula, its textbooks, or its teachers' activities. This contrasts sharply with the coordinated national programs of most other countries.On average, U.S. students study more topics within science and math than their international counterparts do. This creates an educational environment that “is a mile wide and an inch deep”, Schmidt notes.For instance: eighth graders in the United States cover about 33 topics in math versus just 19 in Japan. Among science courses, the international gap is even wider. U.S. curricula for this age level resemble those of a small group of countries including Australia, Thailand, Iceland, and Bulgaria. Schmidt asks whether the United States wants to be classed with these nations, whose educational systems “share our pattern of splintered visions” but which are not economic leaders.The new report "couldn't come at a better time," says Gerald Wheeler, executive director of the National Science Teachers Association in Arlington. “The new National Science Education standards provide that focused vision,” including the call “to do less, but in greater depth.”Implementing the new science standards and their math counterparts will be the challenge, he and Schmidt agree, because the decentralized responsibility for education in the United States requires that any reforms be tailored and instituted one community at a time.In fact, Schmidt argues, reforms such as these proposed national standards “face an almost impossible task, because even though they are intellectually coherent, each becomes only one more voice in the babble.”

'>Throughout the nation's more than 15,000 school districts, widely differing approaches to teaching science and math have emerged. Though there can be strength in diversity, a new international analysis suggests that this variability has instead contributed to lackluster achievement scores by U.S. children relative to their peers in other developed countries.Indeed: concludes William H. Schmidt of Michigan State University, who led the new analysis, "no single intellectually coherent vision dominates U.S. educational practice in math or science.” The reason, he said, "is because the system is deeply and fundamentally flawed."The new analysis, released this week by the National Science Foundation in Arlington, Va., is based on data collected from about 50 nations as part of the Third International Mathematics and Science Study.Not only do approaches to teaching sci

More and more, the operation of our business, governments, and financial institutions are controlled by information that exists only inside computer memories. Anyone clever enough to modify this information for his own purpose can reap substantial rewards. Even worse, a number of people who have done this and been caught at it have managed to get away without punishment.It's easy for computer crimes to go undetected if no one checks up on what the computer is doing. But even if the crime is detected, the criminal may walk away not only unpunished but with a glowing recommendation from his former employers.Of course, we have no statistics on crimes that go undetected. But it's disturbing to note how many of the crimes we do know about were detected by accident, not by systematic inspections or other security procedures. The computer criminals who have been caught may be the victims of uncommonly bad luck.For example, a certain keypunch operator complained of having to stay overtime to punch extra cards. Investigation revealed that the extra cards she was being asked to punch were for dishonest transactions. In another case, dissatisfied employees or the thief tipped off the company that was being robbed.Unlike other lawbreakers, who must leave the country, commit suicide, or go to jail, computer criminals sometimes escape punishment, demanding not only that they not be charged but that they be given good recommendations and perhaps other benefits. All too often, their demands have been met.Why? Because company executives are afraid of the bad publicity that would result if the public found out that their computer had been misused. They hesitate at the thought of a criminal boasting in open court of how he juggled the most confidential records right under the noses of the company's executives, accountants, and security staff. And so another computer criminal departs with just the recommendations he needs to continue his crimes elsewhere.1.It can be concluded from the passage that （ ）.2.It is implied in the third paragraph that （ ）.3.Which of the following is mentioned in the passage?4.What may happen to computer criminals once they are

Beyond PaperworkThe Danish electronics manufacturer, Oticon, is a leader in the move towards the paperless office. In their cafeteria a huge glass pipe runs from ceiling to floor. When the mail comes in, it is immediately scanned into the computer, shredded, and thrown down the tube to the general cheers of the employees. (O) Having all mail and memos available only as computer files to be read on the screen makes it easy to dispense with large physical storage spaces for people who work at desks. （1）Changing over to the paperless office required a rapid increase in computer literacy, but rather than set up a corporate training programme, they turned the problem over to employees. Eight months before the system was installed, they offered each employee a powerful personal computer for use at home in exchange for training themselves to use it. （2）The big change was not the move from paper memos to computer messages. Oticon realised that the more radical transformation is from written to verbal communication. （3） That adds up to a large number of face-to-face exchanges, a big improvement over memos and the occasional multi-hour sit-down consultation typical of the old culture. People do not send each other memos, they talk. As the CEO puts it, “We have jumped through the memo wall and gone right to action.”On the eighth of August 1991, the company left their old wood-panelled offices. （4） Since then they have cut in half the “time to market” on new products. The following year, sales and profits grew more than ever before. （5） In fact, despite a downsizing of 15 percent, employee satisfaction is hitting record highs.Oticon has created an organizational pattern that supports great freedom of action for individuals and teams. They have tied it together with a minimum hierarchy.The first clear results to show up were in the greater efficiencies generated by the fact that less time needed to be spent on management activities. （6）They also have some investment in the success of the project they choose. Oticon has succeeded in breaking the mould and taking a lead in non-bureaucratic organizational design.A.This saving was possible because when people have real choice in the nature of their jobs, they commit themselves to being responsible for their areas of choice. B.They were headed for a new building and a new era in communication. C.Instead, they have large private areas on their hard disks for their correspondence. D.In spite of this, the physical office layout at Oticon is one of its most charming features. E.Over 90 percent accepted, and they organized a club to help one another learn. F.To facilitate this, the on-site coffee bars have now become the venue for about twenty meetings a day, averaging ten minutes and 2.7 participants each. G.So, are people happy with the change? H.Only about ten documents a day, items like legal contracts, escape this treatment.
