This study was conducted to determine the relationship between the Pancasila student profile and students' mathematical literacy skills and to determine the Pancasila student profile affects mathematical literacy skills. Therefore, the data were analyzed using a simple linear regression test because it only involved 1 sample group. The sample in this study was 31 students of class X of the 2024/2025 academic year at a high school or equivalent in Pesawaran, Lampung. The sample determination was carried out using a purposive sampling technique because the researcher could not change the class that had been determined by the school. We chose the school as our research object because it had implemented the independent learning curriculum. Data collection was carried out using test techniques and the Pancasila student profile scale. The findings of the study indicated that no relationship between the Pancasila student profile and students' mathematical literacy. Based on the R Square value, which is 0.001, it shows that the influence of the Pancasila student profile on students' mathematical literacy is 0.1% and 99.9% is influenced by other variables that are not studied. The study was limited to finding out whether there is a relationship between the Pancasila student profile and students' mathematical literacy skills, and knowing to what extent the two variables influence.

Purpose: This study explores how the combination of Problem-Based Learning and Deep Learning pedagogy influences students’ mathematical literacy and disposition, focusing on how both can nurture deeper understanding and sustained engagement. Method: A quasi-experimental approach using a Nonequivalent Pretest–Posttest Control Group design was implemented with 61 participants from MA Mathlaul Anwar Kedondong. The experimental group experienced learning through Problem-Based Learning with Deep Learning principles, while the control group followed conventional instruction. Data from literacy tests, disposition questionnaires, observations, and documentation were analyzed using normality, homogeneity, independent t-tests, and Mann–Whitney procedures. Findings: The integration of the two pedagogical models had a significant impact on mathematical literacy (p = 0.000 < 0.05), reflected in an average N-Gain of 0.57 for the experimental class compared to 0.21 in the control group. Meanwhile, no significant difference was found in students’ mathematical disposition (p = 0.194), although learners in the experimental class demonstrated more stable and constructive attitudes toward mathematics. Significance: Blending Problem-Based Learning with Deep Learning pedagogy effectively enhances mathematical literacy while gradually shaping students’ positive learning attitudes. Continuous and consistent use of this integrative model holds potential for strengthening mathematical disposition in the long term.
