Breast cancer is a serious health problem among women, with incidence and mortality rates that continue to rise. The disease is often detected at an advanced stage due to low levels of awareness, knowledge, and skills related to early detection. Among adolescent girls, particularly high school students, knowledge and skills regarding Breast Self-Examination (BSE) remain limited. This is largely due to restricted access to health information, a lack of targeted educational initiatives, and learning methods that are insufficiently engaging. BSE is a simple and effective early detection method that can be performed independently beginning in adolescence. Video-based education is considered an effective tool for enhancing adolescents’ understanding. This study aims to determine the effectiveness of video-based education in improving knowledge and BSE skills among Grade XI female students at MAN (State Islamic Senior High School) 2 Yogyakarta. This study employed a pre-experimental design using a one-group pre-test and post-test approach. The study population consisted of all Grade XI female students at MAN 2 Yogyakarta, with a sample of 59 students selected through purposive sampling on predetermined inclusion criteria. The intervention involved a single session of a BSE educational video lasting approximately seven minutes. It was conducted in 15 groups, with each group accompanied by one facilitator. Data were analyzed using the nonparametric Wilcoxon statistical test. The Wilcoxon test results showed a p-value of 0.000 (p < 0.05) for both knowledge and skills variables, indicating a statistically significant improvement between the pre-test and post-test scores. In conclusion, video-based education was proven effective in improving knowledge and BSE skills among Grade XI female students at MAN 2 Yogyakarta. Future researchers are encouraged to assess BSE skills using a structured checklist based on standardized evaluation criteria.

This study examines the role of Artificial Intelligence (AI) in enhancing student collaborative learning, with a particular emphasis on AI-driven feedback mechanisms and patterns of student interaction in developing effective collaborative skills. Unlike prior studies, this research highlights the mediating effect of AI-driven feedback on teamwork efficiency and overall learning outcomes in collaborative environments. An explanatory quantitative approach was applied using Partial Least Squares Structural Equation Modeling (PLS-SEM) to ensure robust data analysis. Data were collected from 112 university students who were actively engaged in AI-assisted collaborative learning activities, using a structured online survey instrument. The data were subsequently analyzed using SmartPLS software. The results reveal that AI significantly enhances student interaction (β = 0.534, p < 0.000) and improves problem-solving feedback (β = 0.620, p < 0.000), both of which contribute to significantly strengthening collaborative skills (β = 0.716, p < 0.000). However, the findings also indicate that AI alone does not directly improve collaboration without the support of structured pedagogical design and guidance. Therefore, universities should strategically integrate AI-driven feedback into Learning Management Systems (LMS) and strengthen digital literacy initiatives to optimize the effectiveness and sustainability of AI in collaborative learning contexts.

Language is an important part of human life. Through language, humans can communicate with each other. In addition, language is used to convey ideas, thoughts, opinions, feelings, and thoughts to others. Language also serves as a tool for self-development and interaction with others. A language must have clear meaning so that when communication occurs, there is no misunderstanding in its delivery. Currently, there are several variations of language styles used in society. The existence of these variations is triggered by the rapid development of communication technology. This development has led to different language styles being used by each generation. Each generation has its own used by each generation. Each generation has its own distinctive language style. The use of proper and correct Indonesian is currently shifting and being replaced by slang, so that many people are now accustomed to using slang. This research employs a descriptive analysis and literature review method to examine this linguistic shift. The findings indicate that the high intensity of social media usage accelerates the spread of slang, which potentially diminishes teenagers' formal language skills. Consequently, effective strategies are needed to balance the use of slang as a social dynamic while preserving the Indonesian language as a vital national identity.

Social media has become a primary means of communication for adolescents in the digital era, yet excessive use can create complex impacts on their academic, social, and psychological well-being. The positive effects include expanding cross-regional friendships, improving communication skills, strengthening social relationships, and increasing learning motivation through peer interaction and support. Conversely, the negative effects include declining academic performance due to reduced focus, neglect of responsibilities, weakened language skills caused by the dominance of informal language, a higher risk of digital crimes such as fraud and identity theft, as well as mental-health issues including anxiety, depression, social-comparison pressure, and cyberbullying. To minimize these risks, preventive efforts are needed, such as enhancing digital literacy for both adolescents and parents, promoting ethical and safe online behavior, regulating screen time, strengthening parental guidance, implementing digital-wellness policies in schools, providing counseling services, developing more youth-friendly platforms, and enforcing government regulations on online safety. This study emphasizes that the wise, safe, and productive use of social media can only be achieved through collaborative efforts involving adolescents, families, schools, communities, platform providers, and the government.

Academic stress is a condition of psychological strain that arises when academic demands are perceived to exceed an individual’s capacity to cope. In this context, university students frequently use entertainment related to public figures as an emotion-focused coping strategy, one of which is celebrity worship. This study aimed to describe the level of academic stress among students who engage in celebrity worship. A descriptive quantitative design was employed, with purposive sampling of 230 active university students aged 18–25 years. Data were collected using the Perception of Academic Stress Scale (PASS) and the Celebrity Attitude Scale (CAS). The results indicated that the respondents’ mean academic stress score was relatively high (M = 46.05; SD = 8.38), and the level of celebrity worship was also relatively high (M = 86.10; SD = 15.89). Categorization showed that most students were in the moderate academic stress category (47.0%), followed by high (30.0%) and low (23.0%). For celebrity worship, most respondents were categorized as moderate (49.6%), followed by high (29.6%) and low (20.9%). Crosstab analysis suggested an increasing proportion of high academic stress as celebrity worship levels increased; notably, the high celebrity worship category was dominated by high academic stress (67.6%). Group difference testing also revealed significant differences in academic stress by gender (p < 0.05), with female students tending to report higher stress levels. These findings indicate that celebrity worship may serve as an emotion-focused coping mechanism, yet it may also become a source of distraction when the attachment is excessive. The implications highlight the importance of fostering adaptive coping strategies and time management skills among students to manage academic stress more effectively.
