Differentiated learning is a fundamental aspect of the Independent Curriculum, officially adopted as Indonesia’s national curriculum in the 2024/2025 academic year. Although the curriculum promotes adaptive and inclusive learning tailored to individual student needs, its implementation in Social Studies (IPS) instruction in middle schools in Semarang City encounters significant challenges. This study evaluates the application of differentiated learning strategies, focusing on planning, implementation, and evaluation stages while identifying obstacles faced by teachers. A mixed-methods approach with an embedded concurrent design was employed, combining quantitative data from ANOVA and Pearson correlation tests with qualitative insights from interviews, classroom observations, and document analysis. Data were collected from four representative schools, with Sekolah Mandiri Berbagi emerging as a model for effective implementation through innovative and adaptive instructional strategies. The findings indicate that schools with comprehensive planning and responsive implementation achieve better learning outcomes. However, challenges such as insufficient teacher training, limited resources, and time constraints hinder the overall effectiveness of differentiated learning. These results underscore the need for strengthening teacher competencies, improving educational infrastructure, and adopting more adaptive teaching approaches. This study offers actionable insights to enhance differentiated instruction under the Independent Curriculum, contributing to educational reform in Indonesia.

Lifestyle physical activity in adolescence improve the level of physical activity and movement that young individuals engage in as part of their daily routines and activities outside of structured exercise or organized sports. It encompasses the everyday activities that adolescents do, such as walking, biking, playing. Physical fitness is essential for all ages, but it is significant for adolescence and children. A fit body can lead to a healthy mind and body, so it is important to make lifestyle physical activity a regular part of your life. Adolescence who are physically fit are less likely to suffer from obesity or other chronic health conditions, and they are also more likely to have better mental health. Physically active adolescence has been shown to have better academic performance and social skills. By encouraging your adolescence to be physically active, you set them up for a healthy and happy life, as lifestyle physical activity helps to improve focus and concentration. Being physically fit and well-being can also boost self-esteem and confidence, adolescence learn to appreciate their bodies and what they can do. In addition, PA changes over several transitional periods, including during the COVID-19 pandemic. In many settings, a low level of PA among children occurs as a result of adults’ poor understanding of biological and environmental changes. By understanding the timing and period of the decline or increase in PA, the school, family, and home community can create more opportunities to incorporate PA into a child’s daily life. The Thai government and policy makers can also use the results of this study as evidence in refining their strategies and designing appropriate interventions to improve PA of Thai adolescence people and prevent or delay the onset of non-communicable diseases (NCD) of the population in the long run.

This study aimed to develop and evaluate Augmented Reality (AR)-based learning media to enhance students’ cognitive abilities at State Vocational High School (SMK Negeri) 2 Pati, particularly in the subject of Computer Networking and the Internet. The research was motivated by low student achievement in meeting the Minimum Mastery Criteria (KKTP), which was primarily attributed to the continued reliance on traditional teaching methods and low student motivation. A research and development (R&D) approach was employed using the ADDIE model. The resulting AR media is an Android application that integrates text, audio, images, animations, interactive 3D objects, and simulations, and is in accordance with the Merdeka Curriculum. Expert evaluations showed a very high level of feasibility, with ratings of 94% from a subject matter expert and 91% from a media expert. These results were further supported by Aiken’s V index, which indicated very high validity for the material (0.921) and high validity for the media (0.881). A practicality test was conducted, revealing a high level of effectiveness, with a 94% approval rating from both teachers and students. Moreover, a pretest–posttest control group design demonstrated significant progress in learning outcomes. The experimental group achieved an average post-test score of 83.75, significantly higher than the control group’s 73.60. Based on the N-Gain test, the experimental group achieved an average gain of 65.52% (moderately effective), whereas the control group achieved only 38.75% (ineffective). This study contributes to the theories of learning transfer, connectivism, and heutagogy, and offers practical implications for vocational education in adopting innovative technologies.
