Storytelling as an indirect method of providing a framework for training and promoting self-understanding, efficiency and unity of experiences, can have an effective role on children and teenagers’ health. Therefore, the aim of the study was the effectiveness of training the optimism pattern through the storytelling method on increasing school children’s academic achievement. The research method was quasi- experimental with experimental and control groups. The pre-test, posttest and follow- up stage were administered. To gather the data academic achievement test scores were used. Using the participants in storytelling workshop, the sample size was randomly chosen among the volunteers who added up to 31 people. Using the pre- test scores, matching group was chosen (experimental 15, control 16). The pre-test was administered 3 months after the completion of 12 treatment sessions and a follow- up test was administered six months after the post- test. Using descriptive and inferential statistics (t-test, ANOVA), the results showed that the mentioned method will increase the children’s academic achievement, it also showed that using this method may eliminate or reduce the other academic achievement problems, too.
