Abstract

This study aims to analyze the mathematical literacy skills of grade VIII students at MTS Darul Ilmi Batang Kuis in solving Programme for International Student Assessment (PISA) questions based on gender. This research used descriptive qualitative method. The research subjects consisted of 20 students, including 10 male students and 10 female students selected through purposive sampling. Data collection techniques include data reduction, data presentation, and conclusion drawing. The data analysis techniques used were tests, interviews, and documentation. This study used triangulation as a data verification technique. The problems used in this study were estimated to be at Level 3 (easy), Level 4 (medium), and Level 5 (difficult), and analyzed based on aspects of mathematization, communication, reasoning, and argument. Only two students (one male and one female) reached Level 3. The total score for the male student was 21, while the female student obtained a total score of 20, with the rest remaining at Level 2. Conclusion Analysis was conducted using the scoring rubric and interviews. On average, the results showed that male students' mathematical literacy skills were slightly higher compared to female students. This study recommends the importance of implementing learning strategies that take into account gender differences and strengthen students' understanding of contextualized mathematical concepts to improve overall mathematical literacy.

Abstract

This study aims to determine the effect of the Problem-Based Learning (PBL) model with a STEM approach on students' mathematical problem-solving abilities in SPLDV material. This study used a quasi-experimental approach with a non-equivalent control group design. The subjects were eighth-grade students at MTs Swasta Lab IKIP Al-Wasliyah Medan, divided into two classes: an experimental class and a control class, each consisting of 26 students. The experimental class was taught using the PBL model with a STEM approach, while the control class used a conventional learning model. The instrument used was a mathematical problem-solving ability test. The results showed that the average posttest score for the experimental class was 73.08, while the control class was 59.62. The results of the Independent Sample t-Test show that the value of ????ℎ???????????????????? = 3.341 is greater than ???????????????????????? = 2.009 with a significance value of 0.002 < 0.05, so that H₀ is rejected and H₁ is accepted. Thus, it can be concluded that there is a significant influence of the application of the Problem Based Learning model with the STEM approach on students' mathematical problem-solving abilities.
