The advent of eLearning has transformed traditional educational paradigms, offering new opportunities for Self-Directed Learning and the development of critical thinking abilities among students. This research paper explores the impact of eLearning on these educational outcomes. It investigates how eLearning environments support Self-Directed Learning (SDL) by providing flexible, accessible, and personalized learning experiences. Additionally, it examines the role of eLearning in fostering critical thinking skills through interactive, problem-based, and collaborative learning strategies. The findings are based on a review of existing literature and an analysis of primary data collected from students and educators. The study concludes that eLearning significantly enhances both SDL and critical thinking, though challenges such as digital literacy and access disparities must be addressed to maximize these benefits.
