Situated in the field of technology and language teaching and learning, the current paper reports a mixed-method research study on the use of digital storytelling for developing EFL learners' speaking skills. The purpose of this research study, therefore, was threefold: primarily, to investigate the impact of digital storytelling on EFL learners' speaking skills, secondly, to reveal learners' attitude towards implementing the program, and thirdly, to report students' learning behaviors when using the program. Accordingly, this quasi-experimental study revealed the effect of a 7-week's instructional treatment on speaking skills carried out in experimental group. A traditional method of storytelling was employed in the control group. The instrumentations used for data collection constituted pre and post tests, an attitudinal questionnaire, and a semi-structured interview, which served to collect qualitative and quantitative data, respectively. The results of statistical analysis displayed that there was a trend towards significant gains in the learners' oral production after the treatment. It also documented the learners' positive attitude towards the program.
