Misconceptions on Interpreting and Modeling the Concept of Division Among Elementary School Teachers
Full text linkThis study investigates the nature and extent of conceptual misconceptions held by elementary school teachers in interpreting and modeling the mathematical concept of division. Motivated by the recognition that students’ misunderstandings often originate from teachers’ inadequate conceptual grasp, particularly regarding the use of partitive and quotative models, this research addresses a critical gap in the literature on teachers' mathematical representations. Although division is a foundational concept in mathematics instruction, limited empirical research has explored how teachers misconstrue its meanings in classroom contexts. Employing a descriptive qualitative design within a multiple-case study framework, the study involved 80 fifth-grade teachers from four major Indonesian cities: Jakarta, Bandung, Yogyakarta, and Surabaya. Participants were selected through purposive sampling. Data were collected through classroom observations, semi-structured interviews, and lesson plan analysis. Thematic analysis was used to identify recurring patterns of misconception across instructional practices. Findings in this study revealed misconceptions among many teachers in distinguishing between the partitive (repeated subtraction) and quotative (equal sharing) interpretations of division. This confusion results in the use of inappropriate, rigid, or overly simplified concrete models. The misconception distorts mathematical representations and contributes directly to the propagation of student misconceptions. The most prominent patterns occurred during story problem interpretation, where teachers struggled to match the semantic structure with the appropriate division model. These conceptual misconceptions not only distort instructional representations but also contribute to students' way of thinking. These findings highlight the urgent need for targeted professional development programs. Those would emphasize semantic analysis of word problems and the flexible use of multiple representations. Such interventions are essential to help teachers deliver instruction that fosters conceptual understanding beyond procedural fluency. Aligning teacher training with findings in this study may prevent the transfer of fundamental misconceptions to students and promote deeper mathematical thinking in early education contexts.

Analysis of Students' Mathematical Problem Solving Ability Based on Self-confidence
Full text linkThe purpose of this study was to analyze the ability to solve mathematical problems of students in terms of self-confidence. This type of research is quantitative with a descriptive approach. The data in this study were obtained from tests and questionnaires. The results of the questionnaire were used to classify student’s self-confidence. The test results of the problem solving were then analyzed based on the student’s self-confidence. As a complement to the data on problem solving skills of students, interviews were conducted at each level of self confidence. The results showed that students with high level of self-confidence have excellent problem solving skills with an average value of problem solving skills of 91. Student’s with moderate level of self-confidence have good problem solving skills with an average value of problem solving skills of 74, and student’s with low level of self-confidence have fairly good problem solving skills with an average value of problem solving skills of 51. Keywords: problem solving skill, mathematics, self-confidence. DOI: http://dx.doi.org/10.23960/jpmipa/v23i4.pp1670-167
The Effect of Problem Based Learning with Laboratory Activities on Students’ Problem-Solving Skills
Full text linkThis research is motivated by the low problem-solving skills of students in the kinetic theory of gases and the lack of innovation in the use of models in physics learning. Efforts made by researchers to overcome these problems are by applying a laboratory-based PBL learning model. The purpose of this study was to determine the effect of the laboratory-based PBL learning model on students' problem-solving skills on gas kinetic theory material in class XI IPA SMA Negeri 1 Cilimus. The research method used is a quasi-experimental research design with a pretest-posttest control group design. The results show that after the implementation of the laboratory-based PBL model, it is obtained that is tcount > ttable so that H_0 is rejected, can be concluded that there is an influence of the laboratory-based PBL learning model on problem solving skills in gas kinetic theory material in class XI IPA SMA Negeri 1 Cilimus.

Exploring the Impact of Adversity Quotient on Students' Mathematics Achievement in Junior High School
Full text linkAdversity Quotient (AQ) is an individual’s ability to face and overcome obstacles and has been found to be an important non-cognitive factor in student learning outcomes, especially in mathematics, a subject often perceived as difficult and stressful. This study aimed to examine the effect of AQ on grade VIII students’ mathematics learning achievement at SMP Negeri 2 Parepare. A quantitative approach was used with 36 students selected through cluster random sampling. Data was collected using a validated AQ questionnaire based on Stoltz’s CO2RE model, consisting of Control, Origin and Ownership, Reach, and Endurance, as well as students’ mathematics learning achievement scores. Descriptive analysis showed that students generally had moderate AQ, with the highest dimension score in endurance, which means optimism and persistence, while the control dimension was the weakest. This means that although students are motivated to face challenges, they still struggle to manage their responses to learning pressure. The study applied Spearman’s rho correlation analysis. This finding implies that non-cognitive skills such as AQ in mathematics education will improve their academic outcomes. A high AQ in students will tend to be able to overcome difficulties and problems well it has a good impact on their learning achievement. This study has limitations. Small sample size (N=36) limits generalizability beyond a specific school context. This study only focused on AQ as an internal factor without considering external factors such as socioeconomic status, parental support, or classroom atmosphere. Future research will expand the sample and include additional variables to understand the multifactorial nature of academic success. Keywords: adversity quotient; achievement; learning; mathematics
