This study aims to describe students' mathematical literacy skills in solving statistical literacy questions based on Honey-Mumford learning styles. The statistical literacy questions used in this study are questions of the AKM type which are related to statistical material about the size of data concentration. The subjects of this study were first semester students of the Department of Mathematics, State University of Malang. The instruments used in data collection were test questions, interview guidelines, and instrument validation sheets. The results of the study show that there are differences in the level of students' abilities in several aspects that become competencies in mathematical literacy. Students with a reflective learning style tend to be more detailed in terms of using symbols and mathematical formulas, students with a theoretical learning style tend to be more thorough in understanding and translating the meaning of the questions, while students with a pragmatic learning style tend to prefer using simple reasoning with minimal use of mathematical symbols/formulas.

This research aims to explore students’ proportional reasoning at the early attempts at quantifying stage when students face proportional situations, especially mathematical literacy problems. This research uses a qualitative research approach involving grade 9 junior high school. Data was collected by providing mathematical literacy problems containing proportional situations and in-depth interviews with research subjects. The research results show that students in the early attempts at quantifying stage begin to identify important variables, recognize regularities, and develop plans to solve problems. Students apply inappropriate addition relationships in proportional situations, add or subtract numbers without understanding the concept of comparison, and have a sense of comparing sizes that are bigger and smaller, but students have limitations in understanding the concept of proportionality, especially in recognizing when comparison should be used, students try to identify comparative patterns, students have difficulty connecting patterns to multiplicative forms; able to conclude, but the conclusions are wrong due to limitations in understanding the concept of proportionality which results in inaccurate results. This study provides a novel contribution by specifically focusing on the “early attempts at quantifying” stage, a crucial yet underexamined phase in proportional reasoning development. The findings fill a gap in understanding how students transition from additive to multiplicative reasoning when faced with real-world mathematical problems. The implication is that assistance is needed in the form of exercises that increase students' understanding and sensitivity to multiplicative situations and relationships between variables in solving mathematical literacy problems.

This study explores ethnomathematics in the activity of weaving Buna-Insana motifs and its connection to school mathematics using an ethnographic case study with weavers from Botof Village, Insana District, guided by Bishop's ethnomathematics concepts: counting, measuring, designing, and reasoning. The results of the study indicate that the counting activity, mathematical knowledge in the form of addition operations is obtained. The measuring activity, hand spans are used as a unit of measurement. In the designing activity, the motifs produced are related to plane geometry concepts and similarity concepts. After the designing activity, reasoning activities are carried out. Implication logic is also found in weaving activities, namely when determining the selling price of woven fabrics and the length of weaving time.

STUDENT ERRORS IN SOLVING MCA NUMERACY PROBLEMS ON UNCERTAINTY AND DATA CONTENT BASED ON NEWMAN'S THEORY REVIEWED THROUGH THE LENS OF ADVERSITY QUOTIENT Ashiddiqi, Hasbi; Sukoriyanto, Sukoriyanto; Hidayah, Indriati Nurul

This qualitative study aims to describe the student errors made when solving numeracy problems from the Minimum Competency Assessment (MCA) on uncertainty and data content, based on Newman's theory reviewed through the lens of Adversity Quotient (AQ). AQ is categorized into five types: quitter, transition from quitter to camper, camper, transition from camper to climber, and climber. Among the five AQ categories, only three—quitter, camper, and climber—were represented among the 30 eighth-grade students from SMP Negeri 3 Genteng, Indonesia, who were considered prospective subjects in this research. Therefore, one student from each of these three AQ categories was selected as a research subject, each of whom provided complete answers but still made errors when solving the MCA numeracy problems in the uncertainty and data content. Based on the findings, students in the AQ quitter category exhibited reading errors, comprehension errors, transformation errors, process skill errors, and encoding errors. Those in the AQ camper category exhibited comprehension errors, transformation errors, process skill errors, and encoding errors. Students in the AQ climber category demonstrated comprehension errors, transformation errors, and encoding errors. Keywords: Student Errors, MCA Numeracy, Uncertainty and Data, Newman, Adversity Quotient

This study aims to provide an overview of the mathematical connection skills of MA students when solving contextual problems of linear program material. This research applies a qualitative approach and this type of research is descriptive research. The research was conducted at MA Bilingual Batu with the research subjects being students of class XI MIPA1. Students were given mathematical connection ability test questions in the form of contextual problems and based on the test results were grouped into three groups, namely high, medium, and low. Furthermore, from each group one was chosen as the final subject. The research instruments used were mathematical connection ability test questions and interview guidelines. Analysis of the mathematical connection ability of the research subjects was assessed based on indicators of connections with everyday life, connections with other disciplines, and connections between mathematical topics. The results showed that students with high ability could fulfill the indicators of determining plans or strategies, making mathematical models, applying concepts of other disciplines, and determining and applying mathematical concepts to solve the given problem. Learners with moderate mathematical connection ability are only able to fulfill indicators of determining plans or strategies, applying concepts of other disciplines, and determining mathematical concepts to solve given problems. Meanwhile, students with low mathematical connection ability have not been able to fulfill all indicators of aspects of mathematical connection ability.

Quadratic equations are fundamental mathematical concepts taught at the junior high school level and are widely used in solving mathematical problems. However, many students still experience difficulties and make errors when solving problems related to quadratic equations. This study aims to examine the types of errors made by students in solving quadratic equation problems. The analysis was conducted by reviewing relevant previous studies selected based on predetermined inclusion and exclusion criteria. Seven articles obtained from Google Scholar were analyzed. The results indicate that students
