Teaching online, because it occurs outside the physical classroom, can be advantageous to a teacher with a physical disability. First, it frees one from the constraints of traditional classrooms, which contain many barriers for a teacher who cannot easily walk or stand. Second, psychological barriers that may interfere with the teacher's ability to engage students in the learning process, including students' biases and preconceptions about disabled people, may be bypassed. The teacher's written voice may have more authority than the physical voice without the interference of students' perceptions of the teacher's physical body. Experience teaching online writing courses shows that both teachers and students can benefit from the freedom from concern about appearance and its effect on others.
