Abstract

This study aims to obtain a description of students' critical thinking in solving problems on the system of linear equations of two variables at MTs Alkhairaat Maleni. This type of research is descriptive with a qualitative approach. The subjects in this study were students of class VIII B MTs Alkhairaat Maleni consisting of three people, namely one student each with high, medium and low mathematics abilities. Data collection techniques used written tests and interviews. The results of this study indicate that (1) The critical thinking profile of subjects with high mathematics ability is a subject who is able to master the FRISCO indicators (focus, reason, inference, situation, clarity, and overview). Subjects with moderate mathematics ability are subjects who only partially master the FRISCO indicators, namely the subject does not provide the right reasons to support the conclusions he makes (reason). The subject determines the steps to solve the problem. But the subject is less precise in concluding the solution to the problem (inference). The subject with low mathematics ability, namely the subject who also partially mastered the FRISCO indicator, namely the subject also gave inappropriate reasons to support the conclusions he made (reason). The subject determines the first step in solving the problem. But in solving the problem the subject is not correct in determining the solution strategy (inference). The subject did not use all the information that was in accordance with the problem in the problem (situation). The subject did not recheck what had been done (overview).

Abstract

This study aims to describe the ability of mathematical proof using mathematical induction method of students who have visual, auditorial and kinesthetic learning styles. The subjects of this research are 3 students who are representatives of each learning style, namely 1 student who has a visual learning style, 1 student who has an auditory learning style and 1 student who has a kinesthetic learning style. This research is a descriptive research that describes students' mathematical proof ability using mathematical induction method adapted to visual, auditory and kinesthetic learning styles. The results showed that students with visual and auditorial learning styles were able to perform mathematical proof using mathematical induction in the basic steps and induction steps but only up to the correct assumption for n = k while students with kinesthetic learning styles could not apply the principle of mathematical induction correctly, in th basic steps students substituted n = 1 and n = 2 into the statement and ther were error in arithmetic operations.

Abstract

Background: Many students struggle to understand convergent sequences when they depend on only one form of mathematical representation, which limits how they interpret the idea of a sequence approaching its limit. Aim: This study explores how students who naturally rely on symbolic, visual, or verbal representations experience the process of solving convergent sequence problems. The goal is to understand how they construct meaning, the strategies they choose, and the points at which they feel uncertain when shifting between different modes of representation. Method: A descriptive phenomenological approach was used with seven participants selected through AHP–TOPSIS classification of Dominant Mathematical Representations. Data were gathered from written work, observations, and individual interviews, then analyzed using Colaizzi’s stages. Themes were refined through triangulation to ensure consistency and credibility. Results: Symbolic-oriented students tended to rely on procedural steps and showed little inclination to move beyond formulas. Students who preferred visual thinking used sketches to build intuition but hesitated when expressing their ideas in symbolic form. Those with a verbal orientation explained their reasoning narratively yet were less confident when formal notation was required. Across all participants, shifts between representations occurred rarely, and emotional responses—such as hesitation or relief—often accompanied these moments. Conclusion: The findings indicate that students’ understanding of convergence is shaped strongly by the representational mode they depend on. This limited flexibility suggests the need for instructional approaches that actively support transitions between symbolic, visual, and verbal representations so students can develop a more connected and meaningful understanding of convergent sequences

Abstract

This study investigates the representational transition patterns of pre-service teachers in solving convergent-sequence problems, with a focus on how they utilize symbolic, visual, and verbal representations. Using a qualitative phenomenological design, seven pre-service mathematics teachers were purposively selected based on their dominant representation modes (symbolic, visual, verbal). Participants solved a convergent-sequence task, and their problem-solving processes were analyzed using a modified Colaizzi method, with triangulation ensuring the validity of the findings. Three key patterns emerged: a stagnant reliance on a single representation mode (symbolic or verbal), a linear transition from visual to symbolic forms, and a complementary use of symbolic and verbal representations. No cyclic or complex transition patterns were identified, indicating limited representational fluency. The findings highlight the dominance of symbolic representations among pre-service teachers, with some exhibiting limited representational flexibility. The study suggests that fostering representational fluency, where students can effectively transition between different forms, is crucial for deeper conceptual understanding, especially in abstract topics like convergent sequences. Pedagogically, the study underscores the importance of instructional strategies that encourage the integration and transition across symbolic, visual, and verbal representations. This research contributes to the understanding of representational transition patterns in real analysis, an area often underexplored in mathematics education, and offers insights for improving teacher preparation programs.
