Abstract

This study aims to describe the pseudo-thinking processes of eighth-grade junior high school students in solving algebra problems, as viewed from the perspectives of high, moderate, and low levels of self-confidence. This study was conducted in the eighth grade at SMP Negeri 7 Palu during the 2025/2026 school year. A total of 3 students were selected from a group of 29 students. This research method uses a qualitative approach of a descriptive nature.The researcher employed a self-confidence questionnaire, an algebraic problem-solving test, and interviews. The results indicate that students have high self-confidence in their ability to solve problems correctly and follow problem-solving steps; however, they still struggle to explain their reasoning conceptually, suggesting that their thinking is pseudo-correct. Students with moderate self-confidence are able to solve problems fairly well, but they still make mistakes in their approach and conceptual understanding, so they tend to engage in pseudo-correct thinking, although not to the same extent as students with high self-confidence. Students with low self-confidence tend to have difficulty understanding and solving problems, leading them to give incorrect answers; however, they are able to correct their mistakes after reflecting on them, thus demonstrating pseudo-errors.

Abstract

This study aims to describe the mathematical representations of male and female students in solving algebraic problem. This study employed a qualitative descriptive approach. The subjects consisted of two seventh -grade students from SMP Negeri 9 Palu selected through written tests and interviews. The research results show that during the understanding the problem stage, male subjects used verbal, symbolic, and visual representations, whereas female subjects used only verbal and symbolic representations. During the making a plan and carrying out the plan stages, both subjects used symbolic representations by writing down formulas, forming equations, and performing algebraic operations to arrive at the solution. In the looking back stage, the female subject used verbal and symbolic representations more comprehensively by rechecking the solution and providing a coherent explanation, whereas the male subject only wrote down the final conclusion without performing a thorough recheck.

Abstract

Students still experience difficulties in solving story problems on the topic of equivalent comparisons, so a study is needed regarding problem-solving profiles based on logical-mathematical intelligence. This study aims to describe the problem-solving profiles of equivalent comparisons viewed from the logical-mathematical intelligence of eighth-grade students at SMPN 19 Palu. The study used a descriptive qualitative approach. The subjects of the study consisted of two students who were selected purposively based on the results of Olivia's (2009) logical-mathematical intelligence questionnaire, namely one student in the high category (AST) and one student in the low category (PTR). Data were collected through problem-solving tests and in-depth interviews, then analyzed using an interactive model that includes data condensation, data presentation, and conclusion drawing. The results showed that AST was able to carry out all stages of problem-solving according to Polya completely and obtained correct answers (12 liters). In contrast, PTR was only able to fulfill the stage of understanding the problem, while at the stages of formulating plans, implementing solutions, and re-checking, they still experienced conceptual errors resulting in incorrect answers (5.333 liters). These findings indicate that students with high logical-mathematical intelligence have a more systematic and accurate problem-solving profile than students with low logical-mathematical intelligence.

Abstract

Critical thinking is an important competency in mathematics learning, but many students still experience difficulties in solving problems, especially on the Pythagorean theorem. This study aims to describe the critical thinking profile of eighth-grade students at SMP Negeri 7 Palu in solving Pythagorean theorem problems in terms of mathematical ability. The study used a descriptive qualitative approach with two subjects, namely one student with high mathematical ability (IR) and one student with medium mathematical ability (MN), who were selected purposively based on the results of a mathematical ability test. Data were collected through a mathematical ability test, a Pythagorean theorem problem-solving test, and in-depth interviews to reveal students' thinking processes. Data analysis was carried out through the stages of data reduction, data presentation, and drawing conclusions by referring to the six FRISCO critical thinking indicators according to Ennis, namely focus, reason, inference, situation, clarity, and overview. The results showed that students with high mathematical ability were able to optimally fulfill all FRISCO indicators, while students with medium ability only fulfilled some of the indicators and tended to rely on one solution procedure. These findings indicate that mathematical ability influences the quality of students' critical thinking, so that learning that encourages the use of various problem-solving strategies is needed to develop critical thinking skills more optimally.
