Do Cyber Schools Make the Grade?

Students in Caldwell, Idaho, can attend class in their pajamas!

At Vallivue Virtual Academy, courses are taught online. Students work at home with parents, who serve as learning coaches. A certified teacher oversees the students' progress.

The cyber school was launched as a free option for students in kindergarten through grade 8 who have trouble succeeding in the district's traditional public school. Supporters of the program say that virtual learning can help students work at their own pace. If students struggle with subjects, they can take those courses online and spend more time on them. Valerie VanSelous, a teacher from Hopewell Township, N.J・，agrees. "Teachers, students, and parents need to accept new technology and not be afraid of it. Offering different teaching aids just might be the key to unlocking a student' s potential. "

Some also believe that attending virtual school can prepare students for college and for work after graduation. "We need to be responsible for working on our own,” says Angela Goscilo, a senior from Pound Ridge, N.Y. "We need to develop technology skills that will help us in whatever we do. Getting an early start is a good idea."

Not everyone gives cyber schools a passing grade， however. Some educators argue that online learning makes it hard for students to make friends. Payton Mcdonough, 13, a seventh grader from Glencoe, m., agrees. " I don't know how I could sit at a computer all day without actually interacting with my peers and teachers," he says.

In addition, virtual schools don’t have enough structure. Students who take online courses can set their own schedules, which will cause problems for students who have trouble staying motivated.

Many parents also feel that cyber schools put unrealistic time demands on them because they have to oversee their kids' daily work. Many of them have full-time jobs. How are they going to run their children's education, excel in their jobs, and take care of their other responsibilities at home?
