Abstract
The last decade has been lots of changes in fields of second language teaching. Vocabulary knowledge is said to have a prominent role in learning a foreign language (Schmitt,2000). There has been considerable debate about the most effective way of developing learners' vocabulary knowledge. It is argued that computer - assisted language teaching (CALT) creates more favorable conditions and facilitates second language acquisition, for this reason CALT has been focus of attention of many second/foreign language teachers. The main purpose of this study is to investigate the impact of CALT techniques on FL vocabulary learning in comparison with FL vocabulary learning with traditional method (teachingFL without computer).Two groups of female intermediate learners of English as a foreign language have been taught under different conditions. Before using different methods of teaching, the participants of both groups were asked to complete a recognition vocabulary test as pretest. Thirty students in one class were taught by CALT method and thirty students in the other class were taught by Non-CALT method,(traditional language teaching).The experimental group (CALT) did better than the control group (Non-CALT) in post test. This study concludes that, students taught with (CALT) benefit more inSL/FL vocabulary learning than the students taught with (Non- CALT) .The findings will be useful for language teachers for providing materials for their classes.
