text: The first reason why this technology would be useful in a classroom is so the teachers can adjust the lesson accordingly. For example, if a teacher had planned to talk about Romeo and Juliet which is a morrid tradegy inclduing death, they could switch the lesson and avoid conflict if they knew a student was sad and possibly had a death in their family or relations. If the tecaher had gone into the lesson talking about the death and such upsetting events they could have upset the student and made issues. Another example would be if the teacher saw the student was not understanding the material they could explain the lesson in a different way. One of the main reasons for schooling is to learn and this could help teachers teach their students more efficently. The teacher would know if a student was confused and they could provide them assitance.
