This study investigates the alignment between global competency frameworks and local educational practices, particularly in multilingual classrooms. With globalization influencing education, acquiring skills like intercultural communication and global citizenship is vital. However, integrating these competencies into local curricula remains inconsistent, especially in multilingual settings, where linguistic and cultural diversity pose challenges. Using qualitative methods such as curriculum mapping, teacher interviews, and classroom observations, the study identifies areas of alignment and misalignment. While global competencies are integrated into subjects like social studies and global health education, technical subjects like mathematics and science show less alignment. The study also highlights gaps in the development of intercultural competence and global communication skills, which are often underrepresented. Challenges like language barriers, the monolingual habitus of many schools, and limited professional development for teachers in multilingual contexts hinder the full implementation of global competencies. The study recommends improving curriculum integration of global competencies across all subjects and enhancing teacher training to support multilingual classrooms. Future research should explore regional variations in multilingual settings and how technology can aid in developing global competencies. Addressing these challenges will better prepare students for both local and global challenges in an interconnected world.

Mathematics is a fundamental science that underpins many aspects of daily life.  Where mathematics can be used as a method of solving problems that we face in life activities, such as in using information, knowledge and seeing and using relationships between objects. Not only that, the important role of mathematics includes the formation and development of rational, logical, systematic and critical thinking skills. In the study conducted by Putrihapsari and Fauziah (2020), Nazir (2014) defines literature study as a research approach that involves evaluating a multitude of literature studies that are pertinent to the research being conducted. This strategy is employed in research as a preliminary stage to organise the investigation by gathering data from literature in the subject, without the necessity for direct involvement. By using the PjBL model, it is hoped that it can cover 21st century skills so that it can improve the quality of students' mathematical literacy skills. Given that students must collaborate from the outset, the Project Based Learning (PjBL) learning paradigm may assist them in developing the skills required to work effectively in groups. In order for students to comprehend the rationale and benefits of the mathematics education they receive in the classroom, this learning paradigm is essential for fostering mathematical literacy.
