liu chang I think the avatar can not fully replace human teachers. Firstly,if you are facing a avatar, not a real person, you will not be stressful. But it is no help to make you confident enough to face a real teacher or someone important. Secondly, if you teacher use a avatar, she might not spot his or her student is in the good condition. For example, if the student get bullied by other students in the school, but he or she is afraid to tell the teacher. The avatar probably can not spot it or feel it when the teacher he or herself is not at school. The teacher can not tap the sutdents shoulder, ask nicely , look into the eyes and wheedle him or her to talk.
