This study investigated the effect of producing oral summary of short stories by language learners on vocabulary learning of EFL learners at intermediate level and the possible different effect of this classroom activity on male and female participants. In order to pursue the purpose of the study, one hundred twenty Iranian EFL learners were given Nelson proficiency test as the proficiency test and pretest. Seventy five learners were chosen as the participants for the study who formed one control group and two experimental groups. After twenty sessions of treatment, the participants were given a piloted version of a researcher-made test based on the vocabulary used in the short stories. The findings of the study proved that oral production of short stories can have a positive effect on vocabulary learning among intermediate learners, but the effect of this mode of teaching was not different on male or female language learners. The findings of the study could be used by language teachers who aim at conducting learner-centered language classes and material producers who aim at increasing the outcome of language courses by opting suitable course content.
