This paper examines the impact of storytelling on high school students’ oral performance and their attitudes towards this instruction. Using an experimental mixed methods design, pretests, posttests, and interviews were undertaken with thirty six students in the pilot class of academic years 2017-2018. The findings of the study indicate that these participating students were in favor of learning with storytelling rather than other ways. The quantitative analysis reveals that students in the experimental group outperformed those in the control group, suggesting that storytelling instruction was useful to high school students using the pilot textbooks. Pedagogical implications are also presented.
