Abstract

Abstrak: Penelitian ini bertujuan untuk mengetahui hubungan kecemasan dan kemampuan siswa dalam menyelesaikan masalah matematika di MTs Negeri 2 Pontianak. Metode penelitian yang digunakan adalah metode deskriptif kuantitatif. Sampel penelitian ini 35 siswa kelas VII E. Hasil penelitian menunjukkan bahwa terdapat hubungan linier yang negatif antara kecemasan dan kemampuan siswa dalam menyelesaikan masalah matematika, dengan nilai korelasi Pearson sebesar –,487. Artinya, semakin besar tingkat kecemasan siswa, kemampuannya dalam menyelesaikan masalah akan semakin rendah. Kata kunci: Tingkat Kecemasan Matematika, Kemampuan Penyelesaian Masalah Matematika   Abstract: This research aims to find out how anxiety level affects on students of MTs Negeri 2 Pontianak in their ability to solve math problem. The research used descriptive quantitative method. The sample of this research were 35 students of class VII E MTs Negeri 2 Pontianak. The result of this research showed that there was negative correlation between math anxiety and problem solving ability with the amount of Pearson correlation is –.487. It means more increase the level of student’s math anxiety, the problem solving ability will decrease respectively. Keywords: Math Anxiety Level, Problem Solving Ability

Abstract

This study aims to analyze the relationship between self-efficacy and students' perceptions of problem-solving strategies within the context of mathematical literacy. Using a quantitative correlational approach, this research involved 20 students selected through purposive sampling. Data were collected using two Likert scale questionnaires to measure self-efficacy and perceptions of problem-solving strategies. As the data were not normally distributed based on the Shapiro-Wilk test (p < 0.05), the relationship was analyzed using the Spearman correlation test. The results showed a correlation coefficient (rₛ) of 0.293 with a significance value (p-value) of 0.210. Since the p-value > 0.05, it is concluded that there is no statistically significant relationship between self-efficacy and students' perceptions of problem-solving strategies. Although a weak positive trend was observed, the null hypothesis stating no significant relationship could not be rejected in this study.

Abstract

Problem solving and numeracy literacy are essential competencies in 21st-century mathematics education, as they require students to understand, apply, and interpret mathematical concepts in real-world contexts. However, school assessments remain predominantly procedural and have not comprehensively measured these competencies. This study aimed to develop a contextual essay-based test instrument grounded in ethnomathematics to assess senior high school students’ problem solving and numeracy literacy skills. This research employed a research and development (R&D) method, including needs analysis, test blueprint design, item development, expert validation, limited field testing, and item analysis using the Classical Test Theory approach supported by SPSS. The trial involved 28 twelfth-grade students of SMA Negeri 1 Ketapang. The results showed that the instrument demonstrated very high content validity (average 95.31%) and empirical validity, as student responses reflected the indicators of problem solving and numeracy literacy based on the analytic rubric. The reliability coefficients were very high, with Cronbach’s Alpha values of 0.907 for problem solving and 0.918 for numeracy literacy. All items were categorized as having moderate difficulty levels and good to very good discrimination indices. The novelty of this study lies in the simultaneous integration of Polya’s problem-solving stages and the PISA numeracy framework into an empirically validated assessment instrument based on local ethnomathematical contexts. This instrument provides a more contextual and authentic alternative for assessing higher-order thinking skills in mathematics.
