Rate the following essay on its writing, argument, and language skills:
The use of technology to read students' expresions is good. It could help students focus in school, and help teachers help student with subjects they don't understand.

When students are aware they're not paying attention in a subject they try to pay more attention or at least make it seem like they are. The text states "According to the Facial Feedback Theory of Emotion,moving your facial muscles not only express emotions, but also may even help produce them." This shows that even pretending to focus just by showing it in your face might also help you focu on what going on.

Teachers can aslo benefit from this technology a well. when they teach a class they can look over the students emotions and see what the teachers can do different to make the students understand or pay attention. The text states "A classroom computer could recognize when a student is becoming confused or bored," This shows that the computer can show information about a students emotion which would help the teachers create better lesson plans.

Some may argue saying this would be an invasion of a students privacy and that it would be unfair to the student. It would better to make each student sign a contract that would want to have their emotions monitored and have those who wouldn't want to could just not sign the contract.

In conclusion the use of technology to read student's expressions would be valuable because it could help students pay attention, and help teachers help the students.
