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 valuable to teachers who care what their students are thinking & feeling. The article states "A classroom computer could recognize when a student is becoming confused or bored.."

The article says the computer could detect when a student is bored or confused and then could modify the lesson to where it could interest the student or engage them more than they were before. This could help so many students to understand things more. If they are becoming bored and the computer makes the lesson a bit more exciting or less harder then it could ber so much easier on the students and teachers.

With the power of technology, teachers could see how well they are teaching. If a classroom computer could detect when a student is confused the teacher would then know and could re-explain it to the student. If a student is confused and doesn't want to ask for help in front of everybody the teacher could tell by the computer recognizing confusion and pull the student asside and explain to them again what exactly they're suppose to be doing.

"...if you smile when a Web ad appears on your screen, a similar ad might follow. But if you frown, the next ad will be different." This could be valuable in a classroom beacuse if you are trying to do your assignment on your computer and you see an ad that you may like but you don't want to get off topic from your assignment, you could simply frown and it will go away and bring up something totally different. That may not appeal to you at all and will not distract you from your work anymore.

In conclusion I think the use of technology to read the the emotional expressions of students in a classroom maybe valuable to many teachers. Teacher would then know what exactly their students are feeling without having to ask them. Which could come in handy to tecahers that have shy students and don't like to share how they're feeling or what they think on the discussion.
