A questionnaire survey was conducted for teachers who held classes to foster media literacy in the high schools for the deaf. The classes were often held in a form that combines multiple subjects and areas centered on the information science, and the aim of the classes were mainly to learn the characteristics of various media, communicating in media, handling of personal information, reliability of the media. The main learning outcomes are as follows: 1) Students came to be careful about personal information protection and writing contents in the media, 2) Students came to examine the information through the media, and 3) Students came be able to understand and use the characteristics of various media. Teachers realized the significance of developing judgment, helping students to become independent and participating in society, deepening their knowledge and broadening their thinking through learning about the media. On the other hand, teachers felt difficulty to achieve learning goals in classes because of students’ language skills, to provide guidance on ethics and information morals, to foster awareness of ownership and crisis management, to provide support service regarding teaching materials, and to cooperate between schools and students’ families.
