This study explores the transformative impact of digital technologies on language teaching practices in both formal and informal educational settings. As the integration of tools such as Learning Management Systems (LMS), Artificial Intelligence (AI), mobile applications, and virtual classrooms becomes more widespread, educators are facing new possibilities and pedagogical challenges. This paper critically examines these opportunities and obstacles through literature analysis and qualitative data from language educators. The research reveals that while digital tools promote student engagement, personalization, and access to diverse resources, their effectiveness depends heavily on digital literacy, pedagogical design, and institutional support systems.
