     About 21,000 young people in 17 American states do not attend classes in school buildings. Instead,

they receive their elementary and high school education by working at home on computers. The center

for Education Reform says the United States has 67 public "cyberschools" and that is about twice as many

as two years ago.

     The money for students to attend a cybersehool cotes from the governments of the states where they

live. Some educators say cyberschools receive money that should support traditional public schools. They

also say it is difficult to know if students are learning well.

people say cyberschools help students who were unhappy or unsuccessful in traditional schools. They say

learning at home by computer ends long bus rides for children who live far from school.

cyberschool called Commonwealth Connections Academy will take in students this fall. It will serve children

in the state of Pennsylvania from ages five through thirteen.

technical services. Parents and students talk with teachers by telephone or by sending emails through their
