This study investigates the impact of online learning platforms on the development of self-directed learning (SDL) among university students. With the rapid advancements in educational technology, understanding how these platforms contribute to enhancing SDL is essential for educators and institutions. A narrative review approach was used, focusing on descriptive analysis of studies published before 2021. The findings reveal that platforms like Moodle and Coursera significantly improve SDL skills by offering flexible, accessible resources and tools for setting goals, selecting appropriate materials, and self-assessment. However, challenges such as the need for high levels of self-motivation and sufficient institutional support were also highlighted. These platforms enable students to manage their learning process independently, which is critical in fostering lifelong learning skills. Despite the benefits, the study underscores the necessity for well-designed platforms that provide interactive environments and continuous support to maximize their effectiveness. Future research should explore the impact of individual differences on SDL in online settings and the long-term effects of using these platforms on professional development.
