Abstract: The goal of the study was to develop the writing ability of the study subjects by exposing short story writing as facilitative devices in a language institute in Zahedan. To this goal, two groups of leaners, each 18, participated in the experiment. The population of the study was composed of two intermediate groups of EFL learners in Farhikhtegan Language Institute in Zahedan. All of the language learners, male and female of about 42, made up the study population. To ensure the homogeneity of the subjects, Oxford placement test was used for this purpose. The 36 ones made up the subjects of the study and were classified into two groups. To collect the data, three types of instruments were used. The first, instrument was using Oxford placement test as a device to homogenize the population of the study. The second, instrument was implementing two pre and posttests of writing to determine the initial level of the subjects of the study. The pre-test was taken before the experiment started and the posttest after it finished. The third, instrument was using interview as a device to seek the attitude of the learners of the study on the use of short story writing in the writing class. The data based on the pre and posttests proved the effect of using short story writing on the writing skill of the learners. In fact the EG outperformed the learners in the CG. The difference between the mean scores of the pre and posttest proved that the EG improved more satisfactorily. Besides, the subjects in the EG expressed their positive attitudes towards the use of short story writing in the writing class.
