Critical thinking is believed to significantly support conceptual understanding. This study aims to determine the influence of critical thinking on the mathematical concept understanding of seventh-grade students at MTs Al-Husna.</p> <p><strong>Method: </strong>A survey method with a quantitative correlational approach was used. The population consisted of 70 students, and a sample of 60 students was selected using the Slovin formula. Data were collected through essay tests validated for reliability and analyzed using simple correlation and regression.</p> <p><strong>Results: </strong>The correlation coefficient was 0.261, indicating a low relationship. However, a t-test confirmed a significant influence of critical thinking on mathematical concept understanding (t-count = 2.059 &gt; t-table = 2.000). The coefficient of determination showed that critical thinking contributed 6.812%, while the remaining 93.2% was influenced by other factors such as motivation and intelligence.</p> <p><strong>Conclusion: </strong>Critical thinking has a positive and significant effect on mathematical concept understanding, although its contribution is relatively small. Educators should consider developing students' critical thinking skills as part of learning strategies to enhance mathematical concept understanding.</p> Muhammad Zaidan Indra Martha Rusmana Sumiah Nasution Copyright (c) 2026 Muhammad Zaidan, Indra Martha Rusmana, Sumiah Nasution https://creativecommons.org/licenses/by-sa/4.0 2026-02-20 2026-02-20 1 1 1 6 http://ejournal.auliantech.org/index.php/pytha/article/view/23 <p><strong>Background:</strong> Mathematical problem-solving ability is an essential competency in 21st-century learning. However, field observations indicate that this ability remains low, influenced by mathematical anxiety and students' lack of learning independence.</p> <p><strong>Method:</strong> This study employed a correlational survey method with quantitative analysis. The sample consisted of 77 junior high school students in Karawang Regency, selected using Slovin's formula from a population of 95 students. Data analysis techniques utilized multiple regression with simultaneous and partial testing.</p> <p><strong>Results:</strong> The findings revealed that: (1) There is a significant simultaneous effect of mathematical anxiety and learning independence on mathematical problem-solving ability (sig. 0.000 &lt; 0.05; Fcount = 30.993); (2) There is a significant negative effect of mathematical anxiety on mathematical problem-solving ability (sig. 0.000 &lt; 0.05; tcount = -4.629); and (3) There is a significant positive effect of learning independence on mathematical problem-solving ability (sig. 0.000 &lt; 0.05; tcount = 5.455).</p> <p><strong>Conclusion:</strong> Mathematical anxiety and learning independence significantly affect students' mathematical problem-solving ability. Enhancing learning independence can mitigate the negative impact of mathematical anxiety.</p> Muhammad Tri Habibie Dedy Yusuf Aditya Copyright (c) 2025 Muhammad Tri Habibie, Dedy Yusuf Aditya https://creativecommons.org/licenses/by-sa/4.0 2026-02-20 2026-02-20 1 1 7 17
