text: Teachers are necessary in the classroom not only to impart knowledge but also to make those personal connections that tell them how to best teach their kids. Every student is different, learns a different way and reacts differently to every aspect of the classroom. The article says a computer will be able to detect if a student is bored, but teachers have that ability already, minus the cost and invasion of privacy. Teachers are in the classroom so that they can make those personal connections with each student and ensure that they are doing everything they can to provide the best education possible. If a computer detects boredom it will just try another lesson without knowing what is best for the student. So the question that needs to be asked is why would this sort of technology be useful in the classroom?
