Abstract

Mathematical models are the product of the mathematical modeling stage. One of the causes of students' errors in solving SPLDV problems is changing them to mathematical models and the variety of learning styles that students have. This qualitative descriptive research aims to describe the mathematical modeling students in solving SPLDV problems in terms of learning style. The instruments used were researchers, learning style questionnaires, mathematical modeling tasks, and interview guidelines. Mathematical modeling data is obtained through mathematical modeling tasks which are analyzed based on mathematical modeling indicators and interview results which are analyzed by reducing the data, presenting the data and drawing the resulting conclusions. The results of this research indicate that visual students' mathematical modeling in understanding problems is dominated by using pictorial illustrations. In addition, this study also shows that auditory students experience confusion at the stage of making mathematical models, the process of making mathematical models is not systematic so that it causes confusion. Meanwhile, in mathematical modeling, kinesthetic students do not carry out the checking stage again because they feel confident. Based on the research results obtained, a teacher should develop learning strategies by paying attention to a student's learning style so that students can carry out mathematical modeling according to their learning style. Teachers should also provide visual students with the habit of trying to do calculations with different strategies to strengthen their validation stage. Teachers can also provide practice exercises related to the stages of making mathematical models, so that students with auditory learning styles are more accustomed to working systematically, so that they can reduce the confusion in making mathematical models experienced by auditory students. In addition, teachers should also emphasize kinesthetic students to recheck, so that the results of the solutions obtained can be confirmed to be correct.

Abstract

Critical thinking skills are important for students to have in solving simple and complex problems. This research is a qualitative study which aims to describe junior high school students critical thinking skills in solving numeracy problems. The subjects of this research were three students in VIII class of junior high school. Data collection techniques used numeracy tests and interviews. The results of this research are (1) Students who show interpretation, analysis, and explanation can mention important information in the question narrative and diagrams presented, use various mathematical symbols, and explain the solution steps coherently; (2) Students who show interpretation, analysis, evaluation, explanation, and self-regulation can mention important information in the question narrative and diagrams presented, use various numbers and mathematical symbols, show other ways to solve the problem, explain the solution steps coherently, and check again the steps taken in solving the numeracy problems; (3) Students who show interpretation, analysis, evaluation, inference, explanation, and self-regulation can mention important information in the question narrative and diagrams presented, use various numbers and mathematical symbols, show other ways to solve problems, analyze data and results calculations that have been carried out to make the right conclusions, explain the solution steps again in a coherent manner, and double check the steps taken in solving the problem. From this research, students need to be accustomed to understanding mathematical concepts by using questions in the context of everyday life such as numeracy problems.

Abstract

Inductive reasoning is one of the skills required to solve mathematics problems. As a cognitive process, inductive reasoning is influenced by many factors, including gender differences. This study aims to describe students' inductive reasoning in solving mathematics problems based on gender differences. This research is a descriptive study with a qualitative approach. The subjects were two eighth-grade students from SMPN 6 Tulungagung during the 2024/2025 academic year: one male student and one female student, both with equivalent mathematical abilities. Data collection methods included tests and interviews. Inductive reasoning was analyzed based on the following indicators used by the researcher: (1) observation on particular cases, (2) organization of particular cases, (3) search and prediction patterns, (4) conjecture formulation, (5) conjecture validation, (6) conjecture generalization, and (7) general conjecture justification. The research results indicate that both students observed specific cases, managed specific cases, searched for and conjectured patterns, conjectured formulas, validated conjectures, generalized conjectures, and justified general conjectures. The differences lay in how they acquired initial knowledge and their conjecture validation strategies. The male student acquired initial knowledge based on previously known information and validated conjectures more than once, while the female student acquired initial knowledge based on direct measurement results with the help of a protractor and validated conjectures only once.
