This research compares the effectiveness of online platforms, such as Coursera and edX, and traditional classroom methods in teaching English. Using a mixed-methods approach, the study evaluates learner performance, engagement, and satisfaction across these two methods. Quantitative data reveal that online platforms excel in engagement and flexibility, while traditional methods outperform in interaction quality and completion rates. Qualitative insights highlight the complementary strengths of these approaches, suggesting a hybrid model as an optimal solution. The findings emphasize the importance of tailoring learning methods to individual needs and integrating technology to enhance traditional classroom instruction. Future research could explore the implementation of hybrid models and the impact of emerging technologies on English language education.
