However, limited research has explored the effects of technology-enhanced personalized language learning (TEPLL) on writing skills across different learner characteristics. This study aimed to examine the impact of TEPLL on the writing skills of Iranian EFL learners, considering the moderating effects of proficiency level, age, and gender.<br> <b>Methods:</b> The study was conducted in Fall 2024 with 120 Iranian EFL learners across three proficiency levels (pre-intermediate, intermediate, and advanced). Participants were randomly assigned to either a TEPLL group, which used Moodle for personalized activities, or a traditional instruction group. Writing performance was assessed before and after the intervention.<br> <b>Results:</b> Findings indicated that the TEPLL group showed significantly greater improvement in writing skills compared to the traditional instruction group. The positive effects of TEPLL were particularly evident among higher proficiency and adult learners. Gender did not significantly moderate the impact of TEPLL.<br> <b>Conclusion:</b> TEPLL proves to be an effective approach for enhancing writing skills in EFL contexts, particularly for advanced and adult learners. The results underscore the importance of integrating technology-based personalization and tailoring instructional design based on learner proficiency<b>.</b></span></span></span></span></div> English Writing, Iranian EFL Learners, Technology-Enhanced Personalized Language Learning (TEPLL) 0 0 http://ijer.hormozgan.ac.ir/browse.php?a_code=A-10-362-1&slc_lang=en&sid=1 Fatemeh Moazami Godarzi bahar.moazami1372@gmail.com 0000-0002-0000-0000 No PhD Candidate, Department of English, Isf.C., Islamic Azad University, Isfahan, Iran Hossein Heidari Tabrizi heidaritabrizi@gmail.com 0000-0002-9360-1555 Yes Professor of Applied Linguistics, epartment of English, Isf.C., Islamic Azad University, Isfahan, Iran Azizeh Chalak azichalak@gmail.com 0000-0002-6701-8366 No Professor of Applied Linguistics, epartment of English, Isf.C., Islamic Azad University, Isfahan, Iran
