Numeracy literacy is one of the basic competencies that support students' success in academic and social life. This study aims to analyze the numeracy literacy skills of junior high school students in Sigi Regency, Central Sulawesi Province, Indonesia, particularly in the domain of numbers, based on local wisdom such as the traditional Souraja buildings and agricultural practices of the residents of Sigi Regency. The sample comprised 120 eighth-grade students from six public junior high schools in Sigi Regency, representing diverse geographical characteristics (mountainous, rural, and urban) and varying educational performance levels. They were selected through purposive sampling and the mixed methods approach with an Explanatory Sequential Design as the research methodology. Data were collected using a numeracy literacy test developed using the AKM framework and numeracy competence indicators from the Ministry of Education, Culture, Research, and Technology (2023). The results showed that only 10% of pupils reached the "Proficient" level. Most of them (65%) are in the ‘Basic’ or ‘Requiring Special Intervention’ group. This decline in results is due to traditional teaching methods that fail to connect the material to the students' local environment. Teaching math has not fully utilized local knowledge, such as how to do business in traditional markets and how to farm. These results indicate the need to revise the approach to teaching mathematics in schools, with an emphasis on integrating local knowledge into learning, namely, developing teaching methods that link mathematical concepts to students' daily lives, so that they are more relevant and engaging for students. In addition, this locally-based approach is expected to improve students' numeracy understanding and skills, especially for those who are still at a basic level or need special intervention. The development of a more contextual curriculum based on students' real experiences can also enrich the learning process and encourage significant improvement in academic outcomes. Keywords: numeracy literacy, number domain, local wisdom of sigi.

This type of research is a descriptive qualitative approach. The subjects in this research areClass X MIPA 1 MAN Donggala students consist of 4 people, each 2 male students and 2 female students who have FI cognitive style and FD cognitive style. Data on students' communication skills was obtained by written assignments and interviews. The results of the research show that the mathematical communication skills of students who have a Field Dependent cognitive style are less capable than men because they cannot achieve all the indicators. The student subject has a Field Dependent female cognitive style which is quite capable because it achieves one.The student subject has a Field Independent male cognitive style which is quite capable because it achieves two indicators.The student subject has a Field Independent female cognitive style that is capable of achieving all three indicators. So the conclusion obtained from this research is that students' mathematical communication abilities are generally said to be poor, this is because the majority of students have not met several indicators of the three indicators of students' mathematical communication abilities. This can be seen with only one student achieving all three indicators.

This study describes students' cognitive in solving Pythagorean theorem problems in terms of gender. The research design used is explorative with a qualitative descriptive approach. The research subjects selected were 2 students, namely 1 male student and 1 female student. Data collection was carried out using written assignments and interviews. Checking the quality of the research results using data credibility is done by extending involvement, increasing persistence, discussions with peers, and membercheck and dependability. Data analysis techniques used in this research are data condensation, data display, and conclusion drawing and verification. The results showed that male and female students had raised all commognitive indicators. Male and female students can generally bring up keywords in the form of the words "area of a right triangle 25 ", "perimeter = K", and "hypotenuse c in k". Male students wrote very brief information while female students wrote clear and complete information. The description of the solution written by male and female students is different. The differences found were the use of visual mediators such as visualizing. Male students generalized a as height, b as base, c as hypotenuse while female students generalized a as base, b as height, c as hypotenuse. Endorsed narratives carried out by male and female students can write the formula for the hypotenuse of the Pythagorean theorem, the formula for the area of a right triangle, the formula for the perimeter of a right triangle and the factoring formula. Male and female students can also express the definition of the formula in solving Pythagorean theorem problems. Routines performed by male and female students can choose the right concepts and methods so that they have a good effect on the results of their solutions. Keywords: commognitive, pythagorean theorem, gender. DOI: http://dx.doi.org/10.23960/jpmipa/v25i4.pp1839-1853
