This study's aim was to investigate the effectiveness of video modeling presented with tablet PC on teaching job interview skills to individuals who have developmental disabilities. Participants of the study were two men and a woman whose ages were 21-24 and whose diagnosis was developmental disability. The research was carried out with multiple probe design across subjects which is one of the single subject research models. Dependent variable of the research was the level of the participants' performing the behaviors that they have displayed during job interview with the employer and their level of verbalizing the behaviors which they have displayed for an effective job interview. Independent variable of the research was teaching process with video modeling presented via tablet PC, which the participants used by themselves. The findings of the research revealed that the individuals, who have developmental disabilities, acquired the skill of having job interview and verbalized the behaviors which they should display both before and during an effective job interview. Findings also revealed that, the individuals generalized the information to different environment, to different person and to different situation. Participants could also display the information they learned after the study finished.
