In the present study, the effectiveness of the class that centered on the handicap simulation executed to the students of Department of Education was examined. The class that centered on the simulation in each area of visual impairment, hearing impairment, and physical disability was executed. Afterwards, the questionnaire of the idea before and after the class to handicaps and of the approach that they would be able to do for handicaps was executed to the participant. As a result, for the idea to handicaps, the score after the simulation has increased significantly about four items concerning their attitudes and action, and four items concerning an affirmative, positive opinion to people with handicaps. On the other hand, for the approach that they would be able to do, the category group of “Continued learning and participation”, “Concrete support”, and “Consideration to handicaps” has been extracted. It was thought that having expanded the width of knowledge by integrating their own opinions through the simulation, and hearing others’ opinions led to a score increase about items concerning their attitudes and action, and an affirmative, positive opinion to people with handicaps. However, it is necessary to continue to examine the course content that can urge understanding about handicaps more.
