In software, a bug is an error in coding or logic that causes a program to malfunction or to _3_in correct results.

She is sitting on the bus with her laptop; logging on to the Internet to take a math-skills test in the school home page and get her own personalized assignment. She downloads the software shell need, seeks help from an online school librarian and emails the finished work to her teacher. Mom and dad check in from their office computer, comparing her scores with the class and the state averages.Homework in the future may not any less laborious, but it will certainly be more wired. And as more children gain access to computers and the Net75%of teens and 47% of kids aged 2 to 12 are expected to be online by 2002schools and technology companies are responding with unique assignment and high-tech homework help for parents and kids. On the menu: TAILOR-MADE ASSIGNMENTS. The most profound way homework will change is that instead of everybody heading home with the same lesson; each student will sit down to an individual assignment. The school server, or central computer, will maintain information on each students progress and dole out the appropriate work when the child checks the Web page.Keeping in touch. For students like high school junior Samantha Symonds of Pottstown, pa, the simple ease of getting assignments on line and turning in via emails is reason enough to take homework digital. Samantha, a competitive fencer, travels far from her school for tournament and boots up to stay on top of her assignment. Logging on in hotel rooms and airports, she gets copies of course lectures and lab assignments, emails her teacher when she is stumped and even takes tests on line. “You can actually focus on what you need to know rather than tracking down someone to answer your questions,” Samantha says.Unlimited research. Kids are rapidly becoming experts at searching websites and CD-RoMS for research projects and wowing teachers with what they find. The most profound way homework will change is that instead of everybody heading home with the same lesson; each student will sit down to an individual assignment.Wiring the Have-Nots. As computers become the homework to tool of choice, educators worry about children who dont have access to the technology. “The kids who dont have computers at home will be at such a fundamental disadvantage. It will be as if they dont have a pen or paper,” says Ellyot Solovay, a professor at he university of Michigan. Hes just finished a study in which internet TVs were placed in the homes of a class of Detroit public-school students, and found it not only benefited the kids but boosted parental involvement as well.Yet wining kids over to become fans of homework may take more than high-tech help.
