This study examined how social media shapes students' behaviours and learning processes and how it affects instructional tactics and sustainable development. A survey was given to fifty individuals, whose responses were examined. 25 questions assessed students' media consumption patterns, including social media, their effects on behaviour and learning, and their potential repercussions on sustainable development. This study yielded several intriguing findings. The most notable finding from this study was that most individuals use social media every day, demonstrating that it has become an integral part of their life. Facebook, Instagram, and Twitter had the greatest impact on student behaviour, indicating their pervasive reach. This survey found that social media use affected students' behaviour both positively and negatively. Students report greater peer connectivity, access to diverse views, cooperation, and the use of social media to express creativity and self-expression. Good news. They also noted its usefulness in strengthening these traits, but they also found negative effects, including a decreased attention span due to distractions or a tendency to compare, which could lower self-esteem. The study found that social media significantly impacts how students obtain and use educational content. This affects learning methods. Participants said they learned from social media, connected with educational networks, and participated in study-related online conversations. Social media's accessibility and feed customization can improve personalized learning, according to studies. Customizing feeds on social media aids sustainable development and tailored instruction. These channels also examined teaching approaches and environmentally responsible growth. Social media platforms can help instructors distribute multimedia content, collaborate, and improve critical thinking skills. These platforms can help teachers engage students with multimedia presentations that spark conversation and promote understanding of sustainable development, environmental sustainability, and social justice.
