EVALUATING THE IMPACT OF ONLINE LEARNING PLATFORMS ON ENGLISH LANGUAGE ACQUISITION AMONG UNIVERSITY-LEVEL ESL STUDENTS

This study examines the impact of online platforms, specifically Duolingo and Quizlet, on English language acquisition among university-level ESL students in Uzbekistan. Using a mixed-methods approach combining surveys and platform activity analysis, the research identifies significant improvements in vocabulary, reading comprehension, and motivation. However, the platforms' effectiveness in enhancing writing and speaking skills was found to be limited. The study recommends integrating online tools into blended instruction, with emphasis on teacher feedback and peer collaboration. Future research should include longitudinal studies and explore adaptive digital learning technologies.
