Given the importance of vocabulary in language learning, this study tried to investigate the effectiveness of short message service (SMS) and spacing effect on Iranian intermediate EFL learners’ vocabulary learning. To this end, 60 male and female intermediate learners, aged 17-27, of an English language institute in Isfahan, Iran, randomly selected, were divided into three equal groups, one control group (CG) and two experimental groups (EG1 & EG2) based on the results of a proficiency test, Quick Oxford Placement Test (QOPT). After administering a pretest and during a 6-week treatment, the participants in EG1 received English vocabularies chosen from Oxford Vocabulary Builder book, as well as definitions and example sentences through SMS without spacing and in EG2 with spacing throughout 18 sessions. However, the participants in control group were taught new vocabularies through conventional board and paper technique for the same period. Then, their pre- and posttest scores were compared using a one-way between-groups ANOVA. The results of vocabulary posttest (.15 <.05) indicated that the three groups did not significantly differ on the posttest. The results of this study can have pedagogical implications for language teachers, in that they can use SMS as a useful way of teaching large numbers of vocabularies.
