     The girls in this sixth grade class in East Palo Alto, California, all have the same chance to use computers

as boys, but researchers say, by the time girls get to high school, they may be victims (牺牲品) of what

researchers call "a major new gap in technology".

     "Girls are likely to be less comfortable than boys with the computers. They use it more for word processing

rather than for problem solving rather than discover new ways in which to understand information."

     After reexamining a thousand studies, the American Association of University Women Researchers found

that girls make up only a small percentage of students in computer science classes. Girls usually consider

themselves significantly lower than boys in their ability and confidence in using computers. And they use

computers less often than boys outside the classroom.

     Six years ago, the software company Purple Moon noticed girl's computer usage was falling behind boys.

The number one reason girls told us they don't like traditional computer games is not because they're too

violent or much too competitive. Girls would say they're boring.

     Purple Moon says it found what girls want: characters they can relate to and story lines relative to what's

going on in their own lives. "But we found from girls that there's no intrinsic (内在的) reason why they

wouldn't want to play on the computer. It was a just a content thing." The sponsor (发起人) of the study

says: The technology gap that separates girls from boys must be closed if women are to compete effectively

with men in the Twenty First Century.
