Abstract

This study aims to analyze the mathematical literacy skills of students in underdeveloped, frontier, and outermost (3T) areas, specifically Grade VIII students at SMP Negeri Tiakur, on the topic of circles, in relation to their level of mathematics anxiety. The main focus is to examine how mathematics anxiety affects students’ abilities to understand, represent, and solve contextual mathematics problems rooted in local culture. This research employs an exploratory method with a descriptive qualitative approach. The subjects consist of six students selected purposively based on categories of high, moderate, and low anxiety. Data were collected through an anxiety questionnaire, a PISA level 3 problem, and in-depth interviews. Data analysis included reduction, presentation, and conclusion drawing. The findings indicate that mathematics anxiety influences student performance in solving contextual problems. Students with high anxiety can still demonstrate reflective and procedural abilities if they possess strong conceptual understanding. Conversely, students with moderate or low anxiety may struggle when lacking reflective and conceptual skills. The study concludes that authentic context-based learning, such as ethnomathematics, and attention to students’ affective aspects are essential to enhance their mathematical literacy, particularly reflective thinking and problem-solving skills

Abstract

Students’ mathematical reflective thinking skills are not yet fully developed, especially among students with disabilities. To address this issue, culture-based problems can be applied as a learning approach. This study aims to describe students' reflective thinking skills in solving problems related to Maluku cultural contexts, such as traditional events. This research uses a qualitative approach. The subjects were two students with disabilities selected based on specific criteria from a State Junior High School in Maluku Province, Indonesia. The instruments used were two problem-solving tasks and interview guidelines. Data analysis involved data reduction, presentation, and drawing conclusions. The results showed that one student was able to solve the problem well, demonstrating reflective thinking. However, the other student faced difficulties, especially in the reacting stage, where they struggled to understand the given problems, which hindered the overall reflective thinking process. The progress shown by one student indicates that culture-based problems offer positive benefits for students with intellectual disabilities. Therefore, schools are encouraged to integrate Maluku culture-based content into the curriculum and apply strategies that foster reflective thinking.
