The development of artificial intelligence and algorithms on digital platforms has significantly enriched the understanding of media and algorithmic literacy, especially important for children exposed to tailored digital content. Algorithms on social media determine the order of posts, which users often do not understand. Identity on social media shapes our interpersonal relationships, while freedom of speech on digital platforms faces the challenge of misinformation, requiring a balance between expression and protection from false information. Therefore, media and algorithmic literacy for young people is crucial for their critical approach to the content they are exposed to in the digital world. This study examined the awareness of high school students in the City of Zagreb and Zagreb County regarding artificial intelligence algorithms on digital platforms, aiming to assess their level of media literacy. The research was conducted in May 2024 using a written survey method, involving 206 high school students. The study found that the majority of high school students use digital platforms daily. Students are aware of the existence of algorithms shaping content on their profiles, but their understanding of how these algorithms influence their beliefs and attitudes is limited, highlighting the need for further education. While most students believe they are well-informed about media issues, few are familiar with the concept that digital tools can limit the diversity of information they access. The research also indicates a significant impact of digital content on body image and self-confidence, especially among girls, reinforcing the strong influence of algorithms on students' perceptions and attitudes, necessitating institutional support and additional education in media and algorithmic literacy.
