Abstract

The purpose of this study was to describe the concept understanding ability of students in solving the problem of two-variable linear equation system. The method used is descriptive qualitative research. The subject of this research was 3 students taken from 26 students of class VIII SMPN 1 Balaesang. The results showed that the concept understanding of high mathematics ability students in restating concepts can restate concepts well using their own language, identify examples and non-examples and classify objects according to certain properties in accordance with the concept that can make mathematical modelling and determine equations and use the right solution steps according to the concept algorithmically. The concept understanding of medium ability students in restating concepts has been able to state concepts using their own sentences, identify examples and non-examples and are still lacking in classifying objects according to certain properties in accordance with the concept. The concept understanding of low ability students has not been able to achieve all indicators of concept understanding. Therefore, concept understanding is very important to be mastered by every student and the role of the teacher in facilitating the ability of each student.

Abstract

The integration of ICT in learning is a component of 21st-century learning. Science and technology always develop rapidly from time to time. The purpose of this study is to determine the knowledge and abilities of junior high school mathematics teachers in STEM learning. This research was also conducted to determine student knowledge related to STEM learning. This study used a mixed method. The results showed that most junior high school mathematics teachers in the Donggala district did not understand STEM/STEAM learning. The teacher has also not been able to apply the STEM/STEAM approach in the learning process. Therefore, it is hoped that mathematics teachers in the Donggala district can apply a STEAM-based approach combined with local wisdom in the Donggala district. And it is necessary to conduct training to improve teacher competencies related to STEM learning.

Abstract

This study aims to describe students’ errors in solving Pythagorean theorem problems based on Newman’s Error Analysis (NEA). This study employed a qualitative descriptive approach. The subjects consisted of two eighth-grade students of SMP Negeri 1 Banawa Tengah selected through written tests and interviews. The results show that both students made errors at several stages of NEA, with one student committing more errors than the other. The dominant errors occurred at the comprehension, transformation, and process skill stages. These errors were caused by limited conceptual understanding of the Pythagorean theorem, carelessness in calculations, and haste in answering the questions. The findings of this study provide insights for improving mathematics instruction, particularly in strengthening students’ conceptual understanding and problem-solving skills.

Abstract

This study aims to analyze students’ mathematical connection abilities in solving statistics word problems based on their levels of mathematical ability (high, medium, and low). A qualitative descriptive approach was employed involving eighth-grade students at SMPN 9 Palu. Data were collected through written tests and semi-structured interviews and analyzed using the Miles and Huberman model. The findings reveal qualitative differences in how students construct mathematical connections. High-ability students demonstrate well-structured and flexible connections by integrating statistical concepts, arithmetic operations, and real-life contexts. Medium-ability students are able to establish connections, but these tend to be procedural and lack conceptual depth. In contrast, low-ability students exhibit fragmented understanding and experience difficulties in linking concepts, representations, and real-life applications. This study highlights that mathematical connection ability is closely related to the depth of conceptual understanding rather than merely procedural competence. The novelty of this study lies in revealing distinct patterns of mathematical connections across different ability levels within the specific context of statistics word problems. The findings provide implications for designing instructional strategies that explicitly support the development of mathematical connections in classroom practice.

Abstract

This study aims to describe students' critical thinking skills in solving linear programming problems in grade XII in terms of their mathematical ability level. This study uses a qualitative descriptive approach with three grade XII students selected through purposive sampling technique as subjects, each representing high, medium, and low levels of mathematical ability. The research data were obtained through a linear programming problem-solving test instrument and in-depth interviews which were analyzed through data condensation, data presentation, and conclusion drawing. The results obtained indicate that high-ability students use all critical thinking indicators. They are able to formulate problems, model mathematics, check and solve problems, draw detailed conclusions, write and explain the final answer in detail, and review the answers obtained. Meanwhile, students with medium ability also fulfill all indicators. They are able to formulate problems, model mathematics, check and solve problems, draw conclusions, write and explain the final answer, and review the answers. Meanwhile, low-ability students only master three critical thinking indicators: formulating problems, modeling mathematics, and checking and solving problems. Overall, the difference in students' mathematical ability levels is directly proportional to the depth of achievement of critical thinking indicators in solving linear programming problems.

Abstract

This article contains an exploration of conceptual understanding in geometry lectures in the Elementary School Teacher Education Study Program, Cokroaminoto Palopo University, Odd Semester, Academic Year 2020/2021. This research was conducted through a qualitative approach with the aim of explaining the details of the relationship between concepts in detail and recommending appropriate learning in problem solving. Data were collected using observation, documentation, and written tests. The three techniques are elaborated with the aim of analyzing the concepts and problem-solving patterns of the students' final semester test results. The results of the study explain several findings, namely, Teaching geometry should begin with the process of identifying the important concepts that build up a particular problem. These concepts are then analyzed and linked to one another to form a network. The concept network is then represented in an image/visual display. Through this visual display, lecturers can guide students in compiling procedural steps based on the sequence of concepts that have been compiled. Lecturers need to create meaningful learning for students by connecting previous knowledge with new knowledge through various representations, examples, and manipulations and focus on conceptual understanding rather than procedures or rules.Eksplorasi Pemahaman Konsep Geometri MahasiswaArtikel ini memuat eksplorasi pemahaman konsep dalam perkuliahan geometri pada Program Studi Pendidikan Guru Sekolah Dasar Universitas Cokroaminoto Palopo Semester Ganjil Tahun Akademik 2020/2021.
