Mathematical literacy in the Programme for International Student Assessment (PISA) emphasizes students’ ability to analyze, justify, and effectively communicate ideas, as well as to formulate, solve, and interpret mathematical problems across various forms and contexts. The PISA assessment focuses on real-life problems rather than solely on typical classroom-based questions. Based on cognitive development stages, elementary school students are generally in the concrete operational stage, which means they require tangible objects that can be perceived through the senses. Since mathematics learning tends to be abstract, students need support in the form of media and teaching aids to clarify concepts delivered by the teacher, making them easier to understand. Mathematics instruction is expected to provide an integrated, comprehensive, and holistic understanding of the material. This understanding not only fulfills the demands of mathematical content but also offers practical benefits to students. This aligns with the contextual learning approach, which emphasizes active student engagement throughout the learning process, enabling them to discover concepts independently and relate them to real-life situations. Contextual learning is carried out through four main stages: providing motivation, conceptual understanding, application, and assessment—all of which are grounded in the core components of contextual learning.

In the current data-driven era, data literacy is a critical competency, yet many high school students lack practical training in essential software like Microsoft Excel, creating a significant skills gap. To address this challenge, the Mathematics Study Program at Universitas Kebangsaan Republik Indonesia conducted a community service program designed to empower high school students with foundational data analysis and visualization skills through a structured, hands-on Excel workshop. The program employed a phased approach, beginning with a socialization session for 31 students, followed by an intensive training workshop for a final cohort of 12 students. The workshop was segmented into three progressive modules: Foundations of Data Management, Logical Analysis and Data Interpretation, and Data Visualization. The program's effectiveness was evaluated using qualitative performance-based assessments and a feedback survey to measure changes in skill and confidence. The results indicate that the training was highly successful, demonstrably improving participants' competence and confidence as evidenced by overwhelmingly positive survey feedback. The foundational and data visualization modules were particularly effective, while the module on logical functions was identified as the most significant challenge for students. This initiative not only succeeded in delivering essential digital skills for college and career readiness but also offered valuable pedagogical insights, confirming the effectiveness of hands-on workshops and highlighting areas for refinement in technical education.

Traditional Emergency Health Services (EHS) face numerous challenges, including response time efficiency. The integration of ride-hailing platforms offers an innovative solution, yet public perception of this concept remains underexplored. This study investigates public perception through a quantitative survey of 100 respondents, analyzed as a whole and as two subgroups: those with prior EHS experience (n=48) and those without (n=52). The results reveal exceptionally strong and broad public support for this integration. A key finding is a significant "experience gap": respondents with prior EHS experience demonstrate confident demand with less hesitation, while non-users show more theoretical support with higher neutrality, particularly regarding personal adoption. Despite this difference, both groups show a high consensus on fundamental requirements such as patient safety, driver competency, and the availability of medical equipment. This study concludes that there is high social viability for integrating ride-hailing and EHS. The findings provide a clear mandate for stakeholders to proceed with innovation, on the condition that system development prioritizes the safety and reliability standards expected by the public. This research lays the groundwork for the next stage: the development of mathematical models for a decision-support system to translate this concept into an effective and trustworthy solution. Keywords: ride-hailing, emergency health services, public perception, mathematical modeling, decision-support systems.

Mathematical literacy is one of the essential competencies that needs to be developed in school mathematics learning, as it plays an important role in equipping students to understand, interpret, and use mathematical concepts in various real-life situations. However, the development of mathematical literacy in learning practice still faces several challenges, such as the dominance of procedure-oriented instruction, the limited connection between mathematical content and everyday life contexts, and the lack of instructional strategies that promote students’ reasoning, problem-solving, and critical thinking. This article aims to examine the importance of mathematical literacy in school mathematics learning, identify the challenges encountered in its development, and describe various strategies that can be applied to support the improvement of students’ mathematical literacy. This article employs a literature review approach by examining various relevant scholarly sources related to mathematical literacy, mathematics learning, and instructional strategies. The results of the review indicate that the development of mathematical literacy can be supported through the implementation of contextual learning, problem-based learning, the use of non-routine problems, the strengthening of mathematical representation skills, and the integration of activities that encourage students’ mathematical reasoning and communication. Therefore, mathematical literacy needs to be positioned as a primary orientation in mathematics learning so that students are not only able to solve problems procedurally, but also able to use mathematics meaningfully in everyday life.
