Abstract

The low learning outcomes and problem-solving abilities of students in Palu City are the driving force for finding a student-centered learning model that can improve the problem-solving abilities of high school students in Palu City. This research method is a quasi-experimental design with an intact group comparison design consisting of two groups, namely the experimental class with the RADEC Model learning treatment with a differentiated learning strategy and the control class with direct learning models. The study population was 3656 students, while the sample was 186 students in the experimental class and 186 students in the control class. The researcher selected the sample by purposive random sampling technique. The instruments used were problem-solving ability tests and learning style questionnaires. Data were analyzed using t-test statistics and two-way ANOVA. The results showed that the RADEC learning model with a differentiated learning strategy had a greater impact when compared to the direct instruction model on the mathematical problem-solving abilities of high school students in Palu City, with a significance value of p = 0.000. The average score of problem-solving ability of students who follow the RADEC learning model is 79.63. While the average score of problem solving of students who follow the direct instruction model is 50.72 that the difference in the impact of the learning model is 28.91. The RADEC learning model does not have a different impact on the mathematical problem-solving ability of high school students in Palu city based on learning styles, so that teachers can implement it in classes that have heterogeneous students in terms of learning styles.

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 aims to obtain a problem-solving profile of a two-variable linear equation system for grade VIII students of SMP Negeri 21 Palu reviewed from the student’s mathematical abilities based on Polya steps. This study uses a qualitative method with a qualitative descriptive approach based on the problem-solving steps proposed by Polya. The results of the study showed that the subjects used in this study were three students, namely students with high mathematical ability (ZN), students with moderate mathematical ability (LT), and students with low mathematical ability (KB). The results of the study showed that subjects who had high, medium and low mathematical abilities in solving SPLDV mathematical problems were as follows: (1) in understanding problems, subjects with high mathematical abilities and were reading problems repeatedly, as well as their knowledge of "statement" sentences and "question" sentences. In contrast to subjects with low mathematical skills, they can identify the information available with their knowledge of "statement" sentences and "question" sentences, but subjects with low ability cannot understand every information in the problem even though they have read the problem repeatedly, (2) in planning problem solving, subjects with high mathematical ability and have a solution plan that The same is by using a combined method between elimination and substitution. In contrast to subjects with low mathematical ability who do not have a single mathematical solution plan at all, (3) in carrying out the problem-solving plan, subjects with high and medium mathematical ability can apply problem-solving strategies according to what has been previously planned, in contrast to subjects with low mathematical ability who do not solve problems because they cannot plan problem solving, (4) In re-examining the results of problem solving, the subject with high mathematical ability re-examines the results of his work by re-examining the results step by step of each process to find the answer. Furthermore, subjects with medium and low mathematical abilities do not re-examine their work because the subject cannot solve the given problem.

Abstract

The aim of the research is to summarize the experiences of grade 11 students at SMA Negeri 4 Palu based on Newman's theory. This type of research is descriptive, using a qualitative approach. The research subjects were two students selected from 35 class XI students. The findings of this research are as follows: (1) Not a single subject experienced errors in reading the lesson material, because at that time every subject was considered able to read the lesson material correctly. (2) Not a single subject made a mistake in understanding, as seen in the interview phase. All research subjects were able to provide understandable and questionable information regarding the subject. (3) Each research subject carries out transformation error correction. This transformation error is characterized by the failure of a subset that reduces the problem of the mathematical model. (4) Process skills errors were made by each research subject. This is explained by the subject's understanding of the steps taken in answering the question, but most of it is caused by the subject's errors occurring in the transformation step and the subject being unable to solve mathematical problems accurately. (5) an error in writing the final answer (encoding error) was made by each research subject; This is differentiated by the fact that there are subjects who do not determine the final results of their learning and there are also subjects who fail to determine the final results due to errors in the previous stage.

Abstract

This study aims to describe mathematical communication between male and female students with low mathematical performance and to identify ways to support their mathematical communication skills. Students with mathematical abilities often struggle to express mathematical ideas clearly, making it important to explore their communication patterns and develop effective teaching strategies. A male and a female student from the twelfth grade of high school, were chosen as participants due to their low performance in mathematics. The selection of these subjects was based on the method of pairing data created by Milles. Data collection involved administering tests and using a semi-structured interview approach, which were then analyzed qualitatively. The results of this research indicated that there are differences in mathematical communication exhibited by male and female students. Both participants expressed mathematical concepts by identifying key points obtained from the test. They correctly used mathematical notation and adequately represented their ideas through graphical means. The male student showed a stronger grasp by connecting various concepts. However, there were instances when they struggled to articulate their thoughts accurately in writing. The results of this study provide insights for teachers in designing teaching strategies that improve low-achieving students' mathematical communication skills, both oral and written communication. This is expected to support students in expressing mathematical ideas effectively.

Abstract

The involvement of metacognition in the problem-solving process is paramount. This study aims to obtain a description of the metacognition knowledge of high school students in solving limit of functions problems. This type of research is qualitative descriptive research. The subjects of this study were two students who had high and low mathematical abilities. Data from the results of written assignments and in-depth interviews. The results showed that students with high mathematical abilities in solving limit of functions problems involved the metacognition knowledge they had at each stage of Polya, starting from their declarative, procedural, and conditional knowledge. The subjects with low mathematics at the stage of understanding the problem involved only their declarative knowledge. The step of making a plan involves the declarative knowledge their memory and their procedural knowledge, although incomplete in compiling the ideas. The step of carrying out the plan involves all three knowledge of metacognition that he possesses, while the stage of re- examining involves only his declarative knowledge and his conditional. The results of this research can be a reference in designing limits learning in high school.
