Seventy third-year undergraduate EFL students were selected through cluster sampling and assigned to an experimental group (n = 35) and a control group (n = 35). The experimental group received vocabulary instruction through translation activities based on selected Persian and Arabic poems with published English translations, whereas the control group received conventional vocabulary instruction. Vocabulary development was assessed using the Vocabulary Levels Test, Productive Vocabulary Levels Test, and Word Associates Test. After examining baseline equivalence and statistical assumptions, analysis of covariance (ANCOVA) was conducted to compare posttest performance while controlling for corresponding pretest scores.</p> <p><strong>Findings:</strong> ANCOVA revealed a statistically significant effect of poetry translation-based instruction on receptive vocabulary knowledge, F(1, 67) = 671.56, p &lt; .001, partial η² = .909. A significant intervention effect was also found for productive vocabulary knowledge, F(1, 67) = 596.87, p &lt; .001, partial η² = .899. Similarly, vocabulary depth differed significantly between the groups after controlling for baseline scores, F(1, 67) = 538.94, p &lt; .001, partial η² = .889. Thus, the experimental group demonstrated significantly greater improvement across all three dimensions of vocabulary knowledge, with very large treatment effect sizes.</p> <p><strong>Conclusion:</strong> Persian and Arabic poetry translation-based instruction appears to be a highly effective pedagogical approach for developing multiple dimensions of English vocabulary knowledge among EFL learners. Integrating culturally familiar literary materials with translation activities may facilitate lexical recognition, active vocabulary use, and deeper semantic knowledge more effectively than conventional vocabulary instruction.</p> https://www.qijes.com/index.php/ijes/article/download/1540/1539
