Several previous studies have tried to develop mathematics learning applications, but they are still limited as a learning medium. Developing a digital-based mathematics learning application that facilitates learning from start to finish is necessary. This study aims to develop a viable and effective mobile application. The Development Process uses the CAI design model, which includes needs assessment, design, and development & implementation. Formative evaluations were obtained from expert reviews and students. The experts involved are experts in content, learning media, and multimedia. The formative evaluation stage by students includes one-to-one trials, small groups, and field trials. Research data was collected through questionnaires and test questions. This study involved 1 teacher and 52 high school students in Indonesia. The average score of expert reviews is 3.6, which is in the category of very good. The average score obtained from Formative Evaluation by students is 3.5, with an excellent category. The pretest and post-test scores showed an increase of 40% in students who achieved the completeness of learning outcomes. The average score of N-gain is 0.4 in the medium category. The Ajarin Mobile Application is feasible and effective in improving students' mathematics learning outcomes. This research is expected to be an alternative digital learning resource that makes it easier for teachers to facilitate mathematics learning in schools.

In MR exhibition environments, the integration of AR provides a dynamic approach to increasing visitor engagement, encouraging interactive learning, and enhancing knowledge retention. However, the impact of AR on user experience and educational outcomes in these settings remains underexplored. This study investigates the role of AR in MR exhibitions, aiming to identify both its benefits and challenges. Using a mixed-methods research framework, this study combines qualitative and quantitative approaches to assess AR’s influence on visitor interaction and cognitive processing. Qualitative data is collected through ethnographic observations and structured user interviews, utilizing thematic analysis to identify engagement patterns and usability concerns. Quantitative data is gathered through eye-tracking metrics, user interaction logs, and pre- and post-exhibition knowledge assessments to measure cognitive load, retention rates, and engagement levels. Findings show that AR increases engagement by seamlessly integrating physical and digital elements to create immersive and intuitive experiences. Interactive storytelling and spatial learning mechanisms enhance knowledge retention. However, challenges such as technical limitations, accessibility barriers, and content development complexities restrict widespread adoption. This research contributes to the growing discourse on AR in cultural and educational contexts by offering evidence-based recommendations for optimizing its implementation. By focusing on user-centered design and interdisciplinary collaboration, the study identifies strategies for addressing challenges and maximizing AR’s potential in MR exhibitions. The findings are valuable for curators, designers, and educators seeking to create more effective and engaging exhibition experiences through AR.

Urgensi perlunya dilakukan pengabdian kepada masyarakat yaitu berdasarkan hasil observasi dan diskusi, sebagian guru belum memahami dan melakukan model problem based learning. Untuk itu perlu diadakan worshop terkait hal itu. Pengabdian ini memiliki tujuan meningkatkan kompetensi pedagogik dala menggunakan model problem based learnng. Disamping itu, untuk meningkatkan kapasitas guru dalam menerapkan pembelajaran inovatif yang mendorong kemampuan berpikir kritis, kreatif, kemampuan memecahkan masalah peserta didik. Metode yang digunakan workshop, tanya jawab, diskusi, FGD, pendampingan. Hasil yang diharapkan meningaktnya kapasitas guru dalam melaksanakan problem based learning, sehingga dapat meningkatkan kompetensi pedagogik. Buku problem based learning dengan ISBN 978-623-97614-2-4, dan HKI EC002024205388.

Globalization and modernization have made English proficiency a key factor in student success. However, Indonesia's performance remains low, ranking 79th out of 113 countries in the EF English Proficiency Index, with only 46% of students in Bekasi Regency meeting the minimum standard in 2021. This study investigates the impact of intrapersonal intelligence and learning models. Project-Based Learning (PjBL) and Discovery Learning (DL)—on English achievement among vocational high school students. Using a 2x2 factorial experimental design, 70 students were assigned to PjBL (experimental) and DL (control) groups, categorized by high (B1) and low (B2) intrapersonal intelligence. Data were analyzed using two-way ANOVA and Tukey tests. Results revealed: (1) PjBL led to significantly better outcomes than DL; (2) a significant interaction existed between learning models and intrapersonal intelligence; (3) students with high intrapersonal intelligence in the PjBL group outperformed their DL counterparts by 13.20 points; (4) students with low intrapersonal intelligence performed better with DL, with a score difference of -3.90. These findings suggest vocational English teachers should apply PjBL for students with strong intrapersonal skills and DL for those with lower levels. Policymakers are urged to incorporate emotional intelligence components into national curriculum development.
