In this research, we carried out the questionnaire to the teachers of resource rooms of 57 junior high schools. Based on the result of it, we chose social skills considered to be necessary for students with developmental disorders, such as high functioning autism, LD, and ADHD, and created the video teaching materials for social skills training (SST) of them. They consist of a total of 26 skills, such as self-control, on-task behaviors, and assertion. About each skill, we made both the scene where a certain student does not perform suitable behavior, and the scene where the same student performed suitable behavior. Moreover, we made the guidebook which can be used as reference of SST.

The teacher who actually used these teaching materials reported as follows;
1. They are useful for students to consider more suitable behavior and social skills.
2. By reference of the guidebook, teacher would be able to change the contents and the method of SST easily according to each student's condition.
3. Since they are easy to operate, the students and teachers of regular classes may also be able to use them.

On the other hand, it is required to examine how to choose actually important skills, or to prove training effect, etc. In future study, we should improve these teaching materials, taking close cooperation with school teachers.
