摘要：AbstractThe present study reports the usefulness of online games in vocabulary learning of Iranian EFL students. The participants, (24) low-intermediate EFL learners, were randomly assigned to experimental and control groups. The experimental group learnt some new words via online computer games in 15 weeks. A vocabulary-based test, acting as pre-test and posttest, was conducted in the first and 15th weeks. The findings of the analyzed data indicated that the experimental group outperformed the control group statistically significant in the post-test. Therefore, on line games proved to be more effective in learning English vocabulary for these students.
