Interest in online school courses is surging nationwide, especially at the high school level, according to those who follow trends in educational technology. Much of that demand is coming from those who enroll in just one or two a year to meet a particular academic need or resolve a scheduling hang-up. Online courses have become so popular, in fact, that students simply regard them as another part of their school day--rather than as work to be performed primarily at home. Many students do online assignments at school--with the encouragement of school administrators--in a computer lab or library, before or after school, or between classes. The demand for online education has also brought calls for greater oversight. One teacher observes that she has received special satisfaction from working online with underprivileged students, who are taking standard English courses they need to graduate. Students who are shy or socially awkward excel when removed from the pressures of the classroom.
