       Orlando, Florida — Is it hard for you to get up early and get ready for classes? Some students at Winter

Park High School can quickly get up just in their clothes for sleeping and go to class in their own bedrooms. Of

course, their teachers and classmates do not see them because all their class work is on the computer.

       This school, the state's only online school, has 250 students who are taking classes at home by computer. 

       "I feel a lot more comfortable at home," says Luke Levesque, a 16-year-old student who is taking a

computer class online. He thinks the school's computer lad is so noisy that he can't study well. "Home is much

better," he says. 

       When a student is ready to begin a class, he or she turns on the computer, reads the teacher's instructions

(指示), and begins working on the lessons for the day. What happens if a student has a question for the teacher?

Or the teacher wants to say something about the work a student is doing? The student and the teacher can talk

to each other every day through e-mail or by telephone. For example, when Luke opened his daily e-mail from

the teacher, it contained (包含) her instructions for the day's computer lesson. When he finished, he sent his

work back by e-mail to her for correcting. 

       Is it easy for students to cheat on tests when they're working at home? The teachers have already thought

about this. They make students take their final exams in person in the classroom. 

       If this first online program goes well, in three years Florida's high school students will be able to take all

their classes by computer. When that happens, students will be able to get their high school diplomas (文凭)

without having to set foot in a classroom.
