This study aimed to evaluate the effectiveness of a training package, which was applied through direct teaching method and included digital storytelling, a first aid manikin and live modeling, in teaching basic first aid skills necessary for cuts, sprains and bee stings to individuals with intellectual and additional disabilities. Three middle school students with multiple developmental disabilities whose ages ranged from 12 to 15 participated in the study. The first aid skills for simple cuts, sprains and bee stings were taught in a small group format. A multiple probe design across behaviors with probe conditions, one of the single-subject designs, was employed in the study. The independent variable of the study was training package and the dependent variables of the study were the participants' level of acquisition of the target skills (Cut, sprain and bee sting). The results of the study revealed that the package was effective in teaching simple first aid skills to the participants, and they maintained those skills for 1, 3 and 4 weeks after the completion of training. The participants were also able to generalize the skills to other first aid tools, settings and practitioners. Social validity findings showed that the participants enjoyed the classes in which digital storytelling was used. Also, they expressed their desire to have them in other courses.
