2025-12-01T18:26:13+00:00

Mathematical reasoning ability is an essential aspect of mathematics education, especially for Tadris Mathematics students who are prepared as future educators. One internal factor that may influence this ability is personality type. Introverted and extroverted students differ in the way they process information and make decisions, which may lead to distinct characteristics in their reasoning abilities. This study aims to analyze the mathematical reasoning abilities of students in solving linear programming problems by considering introverted and extroverted personality types at the State Islamic Institute of Kerinci. This research employs a qualitative approach with a descriptive design. The subjects were selected using purposive sampling and consisted of four Tadris Mathematics students whose personality types had been identified through the Myers-Briggs Type Indicator (MBTI) test. The research instruments included a personality questionnaire, a mathematical reasoning test, and interview guidelines. Data analysis was carried out through data reduction, data display, and conclusion drawing. The findings reveal that introverted students tend to demonstrate more thorough, in-depth, and systematic reasoning when solving problems. They are more careful in choosing methods and drawing conclusions. In contrast, extroverted students tend to reason more quickly and directly. They focus more on the final result, present their answers concisely, and are more flexible in selecting problem-solving strategies, although they sometimes pay less attention to process details.

This study was motivated by the low level of critical thinking skills among junior high school students in solving mathematical word probleims, as evident from previous studies and the researcher's initial observations in the field. This study aims to describe the profil of junior high school students' errors in solving mathematical story problems in terms of critical thinking skills. The method used is qualitative descriptive with 32 seventh-grade students as subjects at a public junior high school in South Tambun in the 2024/2025 academic year. The research instrument was an essay test containing five story problems developed based on critical thinking ability indicators, including providing simple explanations, providing further explanations, determining strategies and techniquies, and drawing conclusions. The data were analyzed through the stages of reduction, presentation, and conclusion drawing. The results showed that most students were in the low critical thinking ability category (63%) and the rest were in the moderate category (37%), while no students reached the high category. Students with low critical thinking abilities tended to make mistakes in almost all indicators, while students with moderate abilities were able to meet most of the indicators but were not consistent, especially in determining solution strategieis and drawing conclusions. These findings indicate that the main weakness of students lies in the aspects of strategy planning and drawing conclusions, so mathematics learning that emphasizes the development of critical thinking skills through non- routine story problems and the use of targeted assessment rubrics is needed.

Mathematical critical thinking ability is an essential competence in 21st-century learning, as it enables students to understand, analyze, and solve problems logically and systematically. However, students’ mathematical critical thinking ability in the topic of solid figures with flat surfaces remains relatively low. Therefore, this study aims to describe the profile of students’ mathematical critical thinking ability and to analyze students’ errors in solving problems related to solid figures with flat surfaces based on critical thinking indicators. This study employed a descriptive qualitative approach involving 25 ninth-grade students at UPT SMP Negeri 10 Medan. The research instruments consisted of an essay test designed according to four indicators of mathematical critical thinking interpretation, analysis, evaluation, and inference and an interview guideline to explore the causes of students’ errors. Data analysis was conducted through data reduction, data presentation, and conclusion drawing. The results indicate that students’ mathematical critical thinking ability predominantly falls into the low category, with 22 students classified as low, 3 students as moderate, and no students reaching the high category. The percentage of achievement for each indicator shows that interpretation reached 85.93%, analysis 81.64%, evaluation 75.39%, while inference was the lowest indicator at 18.75%. Interview findings reveal that students’ errors are mainly related to inaccuracies in identifying given and required information, failure to write appropriate formulas, incorrect problem-solving strategies, and the absence of final conclusions. These findings suggest that students’ mathematical critical thinking processes have not been carried out systematically from problem comprehension to conclusion drawing. Therefore, instructional strategies emphasizing structured and step-by-step critical thinking processes are recommended to enhance students’ mathematical critical thinking abilities.
