You are seated in class as your teacher explains and points things out on the white board. You accidentally dropped your pencil on the floor. As you lean over to pick up your pencil, your cell phone falls out of your coat pocket! Luckily you catch it without your teacher seeing, but it is in plain view of the video camera's shiny lens (镜头) that points straight at you. The classroom phone rings, and after a brief conversation, your teacher walks over to your desk and kneels down beside you. “About that cell phone of yours. …” How did that get you in trouble? How could it possibly be a good idea to put cameras in classrooms?

When students are in their classrooms, teachers are in the classroom too, usually. But when a teacher goes out of the classroom, what usually happens is either everything goes on as usual, or the students talk a little more. It is the teacher's job to keep people quiet. If something horrible happened, somebody in class would usually report it, or it would just be obvious to the teacher when he came back that something had happened.

If we already have cameras in the halls, why spend the money to get thirty more cameras for all the different classrooms? Our school district already has a low budget, so we would be spending money on something completely unnecessary.

Different students react differently when there is a camera in the room. Some students get nervous, trying hard to stay focused on their work with a camera focused on them. 90% of students say that they do better work when they are calmer, and cameras are not going to help. Other students look at cameras as a source of entertainment. These students will do things such as wave at the camera, make faces, or say hi to the people watching through the camera. This could be a big distraction for others who are trying to learn and participate in class.

Instead of solving problems, cameras would cause the problems. That is why I disagree with the idea of putting cameras in classrooms. This plan should not be put to action.
