With the rapid development of digital media, adolescents increasingly rely on various digital tools in their learning. This trend has sparked widespread concern in the education community. Studies have shown that digital media not only affects adolescents’ learning effectiveness but also profoundly impacts teachers’ teaching styles. Therefore, this study aims to investigate the impact of digital media on adolescent learning outcomes and its contribution to teachers’ teaching effectiveness. Five secondary school students from different schools and four teachers were selected as the subjects of this study using semi-structured interviews. Through open-ended questions, the researcher guided the interviewees to share their personal experiences and perceptions to ensure the richness and diversity of the data. The study results show that digital media’s impact on adolescents’ learning outcomes is twofold. On one hand, respondents acknowledged that digital media enhances interest and engagement in learning while fostering independent study. However, they also noted that excessive reliance on digital media can lead to distractions. This dual perspective highlights the potential benefits of digital media in education and the risks associated with its overuse, suggesting a need for balanced integration in learning environments. In addition, teachers also indicated that digital media helped to enhance teaching effectiveness by increasing classroom engagement and students’ motivation to learn through interactive platforms. In summary, digital media play a positive role in adolescent learning and teachers’ teaching, but they also pose challenges. Therefore, educators should pay attention to the appropriate use of digital media and advocate a balanced approach to learning to maximise its positive impact on learning outcomes.
