The present study investigated the effect of extensive and intensive listening on the accuracy of tense use among EFL learners in Iran. It was based on pre-test post-test with intact classes. According to the purpose of the study, a sample (n = 60) of homogeneous participants were selected. From among the 6 intact classes, one experimental group (n = 19, 9 male and 10 female participants) was identified to take intensive listening method as treatment, another experimental group (n = 20, 12 male and 8 female participants) was identified to take extensive listening as a treatment, and a control group (n = 21, 9 male and 12 female participants) was identified in order to not take intensive listening or extensive listening activities.
All groups of the study were given pre-test of verb tense usage in order to measure their grammatical knowledge in verb tense prior to the treatments of the study. After finishing twenty five sessions of treatments for all groups, a post-test including verb tense was given to the participants. The data gathered from the study were compared through SPSS. It was found that extensive listening and intensive listening had positive effects on the accuracy of tense use among EFL learners in Iran. In addition it was found that none of intensive listening group and extensive listening group outperformed each other and there was not any significant difference between these two groups' performances.
