The Effect of Using Vocabulary Teaching Software on Iranian Intermediate Efl Learners' Vocabulary Acquisition

A demanding area of foreign language learning is vocabulary acquisition whose significance has always been emphasized by the researchers in the field. The present study is a quantitative exploration of the effects of employing a vocabulary learning software on Iranian intermediate EFL learners' vocabulary acquisition. To this end, fifty- two intermediate EFL learners participated in the study. To ensure their homogeneity, initially, the researcher administered a Preliminary English Test (PET). After excluding the extreme scores, 46 participants remained, who were assigned to experimental and the control groups. Then, a vocabulary test was given to both groups as the pre-test. The experimental group received the treatment which included the use of a vocabulary learning software named Narsis, based on the book entitled 504 Absolutely Essential Words, over a one- month-period of time to observe whether their vocabulary acquisition would improve. The control group was taught the same vocabulary using the 504 Absolutely Essential Words course-book. After the treatment, another vocabulary test was given to both groups as the post-test. The analysis of the results showed that the vocabulary taught was mastered better by the participants receiving the treatment in the experimental group.
