Cameras in classrooms are becoming more common. Often two cameras are used, one in the back to show the teacher and one in the front to show the students. One of the primary rationales behind this use is safety concerns due to numerous school shootings. Monitoring student behavior is another reason for their use.
There are other potential uses. For teacher evaluation, rather than disrupting a class with a personal visit an evaluator could observe the camera feed. Students of teacher education could observe a number of teachers more conveniently with the camera feeds.
What are other positive uses? What are the negatives?
