Rate the following essay on its writing, argument, and language skills:
I'm all for technology to read the emotional expressions of students in a classroom is valuable. When you know peoples expressions. When they are around you you can help them feel better. If you know what they are feeling you can talk to them and make them feel better.

As a teacher your job is to know what a student is feeling. So you can pull them aside but with this machine you will know what they are feeling. So that is one pro here is also a con that what if a student doesn't want you to know what they are feeling.

To wrap it all up my conclusion is yes technology to read the emotional expressions of students in a classroom is valuable should be aloud. So the teacher know if a student is upset or not

so that is a good thing. A bad thing is that what if a kid don't want you knowing what they are feeling.

Score: 2
