Abstract

Indonesian students' mathematical literacy skills remain low, especially in spatial geometry, which requires visualization and a deep understanding of concepts. Conventional learning methods that focus on procedures and memorizing formulas have not been able to facilitate optimal knowledge construction, giving rise to various misconceptions. This study aims to analyze the implementation of the Project-Based Learning (PjBL) model integrated with the STEM approach and its effect on students' conceptual understanding of spatial geometry. The research uses a qualitative approach with a literature review method of national and international journal articles published in the last ten years. The data were analyzed using content analysis to identify consistent patterns of findings related to PjBL-STEM in geometry learning. The synthesis results show that PjBL-STEM significantly improves students' conceptual understanding, mathematical creative thinking skills, and spatial visualization. Contextual project-based learning shifts the learning orientation from memorization to conceptual understanding through activities of designing, constructing, and analyzing real objects. PjBL-STEM is a relevant approach to improve conceptual understanding and develop 21st-century skills. Its success requires careful planning, adequate teacher competence, and facility support for sustainable implementation.

Abstract

Mathematical literacy is an essential competence in mathematics education; however, numerous studies indicate that students’ mathematical literacy in Indonesia remains at a low to moderate level. This study aims to systematically examine the condition and challenges of students’ mathematical literacy in Indonesia, the factors contributing to low mathematical literacy in conventional instruction, the implementation of Problem-Based Learning (PBL) integrated with differentiated instruction as a learning solution, as well as the strengths and limitations of applying differentiated PBL in mathematics learning. This study employed a literature review method by analyzing 21 relevant scientific articles published between 2023 and 2025. Data were analyzed using a qualitative descriptive approach through the classification and synthesis of research findings based on four analytical focuses. The findings reveal that low mathematical literacy is characterized by students’ difficulties in understanding contextual problems, modeling mathematical situations, and interpreting solutions. The main contributing factors include teacher-centered instruction, the dominance of procedural exercises, limited real-world contexts, and the lack of accommodation for students’ diverse characteristics. The implementation of differentiated PBL has been shown to effectively improve mathematical literacy and its supporting skills, although challenges remain in terms of lesson planning, time allocation, teacher readiness, and authentic assessment.
