Metacognitive skills are increasingly acknowledged as a decisive determinant of mathematical proficiency, as they enable students to plan, monitor, and evaluate their cognitive strategies in problem-solving. However, empirical studies rarely focus on how these skills are exhibited by students with low self-efficacy, a population particularly vulnerable to persistent underachievement in mathematics. Addressing this gap, the present study provides novel insights into the metacognitive functioning of low self-efficacy students when engaging with problem-solving tasks, specifically in the context of the Pythagorean Theorem. The study aimed to describe the manifestation of metacognitive skills among junior high school students with low self-efficacy and analyze their problem-solving strategies and underlying thought processes. Employing a descriptive qualitative design, participants were identified as low self-efficacy students using a standardized questionnaire. Data were obtained from self-efficacy questionnaires, problem-solving tasks, and semi-structured interviews, and subsequently analyzed through metacognitive indicators embedded within Polya’s problem-solving framework. Findings indicate that while low self-efficacy students exhibited consistent awareness and evaluative monitoring, their regulatory skills were less developed, particularly in the reviewing stage of problem-solving. Although planning and assessment strategies were evident, frequent errors required iterative adjustments before arriving at correct solutions. These results highlight the intertwined relationship between metacognition and affective-motivational factors, suggesting that mathematics instruction should explicitly integrate self-efficacy enhancement with metacognitive training. The study contributes to advancing the theoretical discourse on mathematics learning and offers practical implications for designing instructional models that accommodate learners with diverse motivational profiles.

Mathematics plays an important role in daily life, but students often have trouble solving word problems, especially on the topic of direct proportion. This difficulty highlights the need for a profile of students' problem-solving processes to help teachers identify where learning challenges occur. This study aims to describe the problem-solving profile for direct proportion based on the logical-mathematical intelligence of eighth-grade students at SMPN 19 Palu. The research used a descriptive qualitative approach. The subjects of the study were two eighth-grade students chosen based on the results of logical-mathematical intelligence questionnaire, each representing the high (AST) and low (PTR) categories. Data was collected through written tests and in-depth interviews, then analyzed using techniques of data condensation, data presentation, and drawing conclusions. The research results show that AST was able to complete all four stages of Polya completely and accurately with the correct answer (12 liters), while PTR only managed to understand the problem stage and made fundamental conceptual mistakes in the next stages (wrong answer: 5.333 liters). PTR also couldn't verify the answer. It was concluded that mathematical logical intelligence has a decisive influence on the quality of solving ratio problems at each stage of Polya.
