Within nine years, all students in grades 4 and higher will have their own computers. Back in Bloomfield, in the meantime, most of the _ have been worked out. Some students were using their computers to visit unauthorized websites. But teachers have the ability to keep an eye on where students have been on the Web and to stop them.
