    Raegan Byrd tries to complete her homework every night. But the high school student in Hartford, Connecticut, has to use her mobile phone to search for the necessary information because she does not have internet connection at home.

In May, the US Department of Education(DOE) published its findings that the number of homes without access(接入) to internet has been getting smaller, but 14 percent of homes in city areas and 18 percent of homes in the countryside still do not have internet connections.

In some states, the problem is much more serious. For example, in the countryside of northern Mississippi, a third of the 294 homes in Maben do not have computers. And close to half have no access to internet whether they can pay for it or not.

Sharon Stidham, a mother in Maben, has to take her four boys to the school library at East Webster High School. Her husband works there, so the children can use the internet for their schoolwork. A signal tower can be seen through the trees from their home, but they could not put aside any money for the internet.

Research results from the National Center for Education(NCE) have shown that students with internet at home get much better scores in reading, math and science than the ones who do not.

Some teachers call this problem “the homework divide”. Jessica Rosenworcel, an NCE member, said, “The so-called homework divide is the cruelest part of the digital age and it is hurting the poor students and creating a big obstacle to their dreams.”

Local communities(社区) have started to help. They made lists of restaurants and other businesses with Wi-Fi places where children are welcome to come and do their homework. And many public libraries have also planned to provide free access to the students next year.
