Abstract

Numeracy literacy is one of the essential competencies that enables students to solve mathematical problems, including systems of linear equations in two variables, which require the ability to understand, process, and interpret contextual information. However, this ability is influenced not only by conceptual mastery but also by students' belief in their own capabilities (self-efficacy). This study aims to analyze students' numeracy literacy and explore their experiences in solving systems of linear equations in two variables based on different levels of self-efficacy using a qualitative phenomenological approach. The research subjects consisted of three eighth-grade students from SMP Negeri 2 Sepatan who were purposively selected to represent high, moderate, and low self-efficacy categories. Data were collected through a self-efficacy questionnaire, a numeracy literacy test, and in-depth interviews, and were analyzed using data reduction, data display, and conclusion drawing. The findings revealed that students with high self-efficacy experienced the problem-solving process by effectively utilizing information, rechecking their answers, and appropriately interpreting the results, whereas students with low self-efficacy experienced difficulties in understanding information and determining appropriate solution strategies. These findings indicate that differences in self-efficacy are reflected in how students experience the problem-solving process, from comprehending information to interpreting the results obtained.
