Rate the following argument fragment on its writing, argument, and language skills:
Evidence: If a student is feeling sad or feeling stressed about home problems which they are trying to conceal, then the technology detects this and displays it for the teacher and the electronic lesson to see. This is an invasion of privacy, as the teacher does not need to know about a student's homelife or about their feelings outside the classroom. A teachers job should be to monitor how their students are feeling about their lessons, not about how their students are feeling about their life outside of school, and since this technology could pick up on digressing feelings, it should not be used in a classroom where a student's internal feelings are revealed to a teacher. Therefore, using Facial Action Coding could end up being an invasion of privacy that should not be introduced to the classroom.
