摘要:In the twenty-first century, integration of technology into education is a force worthy of contemplation. Among all the possible technological tools that can be integrated into EFL classes, computers seem to have achieved a more dominant position. One of the outstanding features of computers is their potential to present educational games and to add fun to grammar learning. This study investigated the possible effects of the integration of CALL technology on young Iranian elementary EFL learners' grammar gain. Moreover, it examined the role of length of exposure to find an optimum balance for the proper amount of CALL integration to language activities. One control and two experimental groups, each consisted of 15 participants, were engaged. One of the experimental groups used CALL technology for twice as long as the other group. 'Family and Friends 2' with its accompanying MultiRom was utilized in the experimental groups. This software presented computer-based grammar activities. All the participants tried their answers in separate immediate as well as delayed post-tests. The results of one way ANOVA demonstrated significant differences between control and experimental groups in the immediate post-test. The findings of the delayed post-test showed that a significant difference did exist between the control group and the second experimental group. Furthermore, the length of exposure was found to be influential. The results of this study provide some insights for teachers and administrators to review their curricula, approaches, and educational tools, and to consider the possibility of incorporating CALL technology into their teaching environments.
