text: Any body can teach them anything as long as the other student and the trainer want to put in their time and extra effort then they can achieve any thing. They just have to put their minds together because two minds are better than one. So if they try to succeed than they will because effort is more than anyone would imagine.                  I believe that using this technology to read students' emotional expressions is a bad idea, most people hide their emotions for a reason. Whether its struggle in class or things happening at home, they'll talk about it if the teacher can help but its best to keep those things to yourself and figure out how to deal with it or talk to a professional about those things. In some cases it may help, some people might become dimented or tormented by something on their mind and make rash discisions that harm themselves and others around them. The new technology would probably be very expensive and difficult to implament and gain the permission from parents and school officials who may be confused about it. Many schools are struggling with money and financial issues and there are far more important things to do and invest on rather than spending money on technology that may not even work 100% and only add on to problems.
