Stoll was exaggerating when he wrote his article. Obvioulsy kids are not going to be left alone to make their own education. That is the equivalent of leaving children home alone to get into trouble. Wallis is more realistic in her article. She realizes that the teacher will still be essential to learning becuase he or she will need to keep the kids in line.
Someone has to make the computers go.
Wallis points out on page 392 that the roles of teachers have changed. She knows that the computer is a tool and that teachers will use them to help teach, not to do all of the teaching. This doesn't mean that teachers will abandon their posts. That too is one person's opinion, but they can use the technology to explain the conventional explaination.
