Inn Ayres
Something alarming happened in my contract law class. I asked that laptop computers be used only for note taking, and my students went ballistic.
Solitaire and Minesweeper are everywhere now in university classes. At Yale, where classrooms are wired to the Internet, students can also surf the Web, send e-mail or even trade stock. Soon the wireless Internet will make this possible at all schools.
Not all students do this sort of thing. But the abusive use of laptops is getting to be increasingly prevalent. Students toggle between windows during any part of the class they deem to be boring—often when their fellow students are asking questions or answering them. Seeing the person in the next seat playing a video game while you are trying to puzzle out a law question is demoralizing. And students who surf are not fully present to ask or answer questions themselves.
Admittedly, students can mentally check out of the class in other ways, for instance, by daydreaming or doodling. But not all activities are equally addictive, I should know. I might be the only law professor to have asked for cybersitter filtering so aware to keep me from surfing the Web too much at my office.
Still, I was surprised at how brazenly my own students resisted to my laptop restrictions, both in class discussion and in virtual chat room (which, perversely, they could post to during their other classes.) they argued that they were multi-tasking, staying productive during dead or badly taught portions of class. They said classroom surfing reduces sleepiness, increases their willingness to attend class. allows them to research legal questions being discussed, and so on. They said the professor has incentive to teach more effectively when he or she must compete against other more interesting claims on students" attention.
Their arguments could apply equally well to the opera hall,the jury box,or the church pew. Will the lure of technology stimulation someday overwhelm current mores about paying attention in those places, too? At least we should try to stem the tide in the classroom. Few students say in their admissions applications, after all, that they intend classroom solitaire to be a central part of their education experience.
问答题A century ago American men outnumbered and outlived the women. But in the 20th century, women began living longer, primarily because pregnancy and childbirth had become less dangerous. The gap grew steadily. In 1946, for the first time ever in the United States, females outnumbered males.
Part of the reasons are self-inflicted. Men smoke more than women, drink more and take more life-threatening chances. Men are murdered (usually by other men) three times as often as women are. They commit suicide at a higher rate and have more than twice as many fatal car accidents as women do. Men are more likely to be involved in alcohol-related fatalities. Men drivers!
But behavior doesn"t explain away the longevity gap. Nor is stress the answer. In the 1950s, as heart disease claimed more and more male victims, pressure in the corporate boardroom was blamed. Let women venture out of the home and into the line office, doctors said, and they would begin dying at the same rate as men. But a funny thing happened on the way to the funeral. Between 1950 and 1985, the percentage of employed women in the United States nearly doubled. Those working women, several studies have found, are as healthy as women at home.
