text: Another reason why schools should use this system is because test grades would start to increase. As kids are trying harder on their work because it is something they enjoy, they will start trying harder on tests. Most kids do not give much thought on their work in class which overall leads to bad test grades. If kids told their teachers they were bored with the assignment they were learning, the teacher would not just stop teaching and change to a different topic, but a computer would. The passage says, "Then it could modify the lesson, like an effective human instructor."
