Rate the following essay on its writing, argument, and language skills:
The use of technology to read the emotional expressions of students in a classroom is not valuable in a student classroom. Teachers should be able to tell when a student is happy, sad, or angry. This isn't a good idea because it's a big risk money wise, is not guranteed to do its job, and most students wouldn't allow a computer to scan their face.

This idea isn't good because in order to do this, the creator will have to risk a very large amount of money. The computer sounds like it will be a success but it really won't. If this computer was built it will be very expensive and most schools wont be able to afford it. If they want to make something like this it shouldn't be used to calulate someone's emotions.

Another reason why this idea really isnt good is because the computer is not guranteed to do its job. Not everything goes as planned, and a computer can't scan somebody and expose how they feel. Making this will be a waste of time and money that can be put into something else that's better. Why make a computer to tell how somebody feels when your famiy or friends can easily tell how you feel by the look on your face with no computer.

In reality, most students wouldn't allow a computer to scan their face because it will make them feel uncomfortable. A student wouldn't want to sit in front a computer and listen to the computer tell how they feel. The text states that if you smile when a web ad appears a similar ad will follow, and if you see a ad you dont like the next one will be different. So making this computer will not be a valuable thing in a student classroom.

In my conclusion this computer will be a waste of time if it was actually created.If this computer was actually going to be made it will be a big risk of losing a lot of money. The computer also isn't guranteed to do its exact jon and most students wouldn't allow for a computer to tell them how they feel.
