Through digital circuit examples of the experimental system, Modern Education Technology introduced in the hearing-impaired students in the application of classroom teaching, analysis of the superiority of its operability. According to the teaching of specific content, built on true, real circuit experimental system, through its flexible software simulation and hardware realization of the creation of a new teaching model, teaching methods. Modern Education Technology in teaching, knowledge of abstract theories to the real show, a great solution to the students understanding of theoretical knowledge at the time of challenge for the hearing-impaired students in a classroom teaching in higher education a teaching method for reference.
