Abstract

Abstract: Problem-solving in mathematics is a fundamental skill that must be mastered by individuals. However, previous research indicates that students' problem-solving abilities tend to be moderate to low. Many factors contribute to this, including the factor of number sense ability. The objective of this study is to describe how number sense and problem-solving skills are used by mathematics education students with low number sense ability in solving linear programming problems using the simplex method. This research is qualitative descriptive involving 36 third-year mathematics education students as participants. Subjects were selected using purposive sampling technique based on a number sense ability test to identify those with low number sense ability. Participants were given an advanced test involving linear programming problems solved using the simplex method. The results indicate that mathematics education students with low number sense ability struggle to solve problems accurately. Stages of problem-solving that were not performed effectively included gathering information, planning, and implementing the plan. Furthermore, students did not engage in the reviewing stage. Moreover, students were not flexible in manipulating numbers, especially when dealing with large numbers. As a result, more time was required for computations, and the iteration process in the simplex method could not be effectively completed.        Keywords: linear programming, number sense, number sense ability, problem solving, simplex method.DOI: https://dx.doi.org/10.23960/jpmipa/v25i1.pp103-115

Abstract

Math majors must be excellent problem solvers because problem-solving is the foundation of teaching mathematics. Their problem-solving skills will help them create service initiatives as math teachers. This research investigated how well the APOS-based PBL model enhances students' skills in solving mathematical problems. This quasi-experimental design used a non-equivalent post-test-only control group, which is quantitative. Students at a university in Central Java, Indonesia, participated in the study. Tests of problem-solving skills were useful to collect the data. The results of the study showed that (1) students' problem-solving skills lead to learning completion (71); (2) students taught using a modified PBL model based on APOS theory have a different proportion of learning completeness than students taught using an average class using a direct learning model; (3) students' average problem-solving skills taught using the modified PBL model based on APOS theory are superior to those taught in the average class using a direct learning model; (4) increasing students' problem-solving skills taught using a modified PBL model based on APOS theory is preferable to improving students' skills taught using a direct learning model. This study offers insightful insights into the PBL model's implementation, incorporating APOS theory at every stage. These results suggest that to maximize students' problem-solving skills, consideration of the theory of thinking processes must be given when putting the learning model into practice      Keywords: APOS, mathematics, PBL, problem-solving skills.DOI: http://dx.doi.org/10.23960/jpmipa/v25i3.pp1577-1592

Abstract

Improving problem-solving in mathematics education can be achieved by applying a Problem-Based Learning (PBL) approach that prioritizes active student involvement. This research offers a PBL model that is integrated with digital technology to improve students' problem-solving skills more effectively and efficiently. This study aims to analyze the effectiveness of the implementation of the problem-based learning model in improving the problem-solving ability of junior high school seventh-grade students. The research method used was quasi-experimental with a pretest-posttest design of the control group. The research sample consisted of 66 randomly selected seventh-grade students. The selection of 66 students as a research sample was carried out to ensure adequate representativeness, taking into account the diversity of academic backgrounds and problem-solving skills, so that the results of the study can accurately describe the impact of the implementation of Problem-Based Learning (PBL) on various levels of student ability. The instruments used include problem-solving ability tests berjumlah 5 soal and observation sheets for learning activities. The data analysis technique used was the Mann Whitney to see the difference in improvement from the two groups of research samples. The results showed that students' mathematical problem-solving skills experienced a high improvement (Ngain = 0.813) after learning mathematics using problem-based learning. Furthermore, the implementation of the problem-based learning model significantly improves students' mathematical problem-solving skills. These findings indicate that open-ended problem-based learning is one of the effective alternative interventions in improving students' mathematical problem-solving skills. Therefore, educators in the field of mathematics, such as teachers and lecturers, can use open-ended problem-based learning to improve students' mathematical problem-solving skills.         Keywords: problem-based learning, problem-solving skills. DOI: http://dx.doi.org/10.23960/jpmipa/v25i3.pp1067-1079

Abstract

Abstract: The purpose of this research is to develop a ludo media called cheerful math ludo (Domaria), which is integrated with the TGT model to solve fifth-grade math story problems based on the material of the volume of space. The type of research used is R&D with the Borg and Gall model. The stages in this research are analyzing problems, collecting data, making product designs, design validation, design revisions, small group trials, product revisions, and large group trials. Based on validation from media experts of 91.7% (very feasible), material experts of 91.7% (very feasible), and language experts of 81.3% (very achievable), as well as the results of teacher and student responses of 100% (very feasible), it shows that Domaria media is suitable for use. This can be seen from the results of the paired T-test in small groups with a Sig value. (2-tailed) 0.000, which means that the average post-test value has increased when compared to the pre-test value. Then, the N-Gain test in the small group obtained a result of 0.627, which means that it is effective in the medium category. The same thing happened in the paired T-test test in the large group, which showed a sig value. (2-tailed) 0.000, which means that the average post-test value increases from the previous pre-test average. The large group N-Gain test showed a value of 0.699, which was said to be effective in the medium category. Thus, Domaria media integrated with the TGT model is proven to be effective for teaching and learning.     Keywords: learning media, ludo, TGT model, mathematics.

Abstract

Several studies have been conducted to improve students' representational competence in physics, but a comprehensive review of these efforts is lacking. This manuscript summarizes current knowledge, identifies gaps, and suggests future research directions to improve students' representational competence. A review of 26 scientific articles from 2000 to 2023 in physics education journals was conducted. The findings revealed that (a) a consistent learning approach can improve students' representation competence, (b) constructivist-based learning models show a significant impact on the understanding of various forms of representation, (c) interactive learning media, such as simulations and animations, are more effective than conventional media, and (d) media that integrate local cultural elements have the potential to increase student engagement and understanding. However, the study also found limitations in the development of media that support low-achieving students, the integration of technology into representation learning, and long-term research on the impact of learning interventions. The main implication is the need for a more integrated and technology-based approach to improve representation competence across different levels of students. As a novel contribution, this study recommends the development of Android-based applications for physics representation training, testing the effectiveness of local culture-based media, long-term impact research, and evaluation of user experience and feedback to strengthen future learning designs.        Keywords: representation competence, increased representational competence, next effort, literature review.DOI: http://dx.doi.org/10.23960/jpmipa/v25i4.pp1906-1924

Abstract

The purpose of this study is to analyze the implementation of the STEM approach (Science, Technology, Engineering, and Mathematics) in Indonesia, particularly in high schools, through a systematic literature review. STEM is recognized as an innovative learning method that integrates various disciplines to enhance 21st-century skills, such as critical thinking, problem-solving, and student creativity. The analysis reveals that the implementation of STEM positively impacts student outcomes, interest, and motivation, especially in project-based and technology-driven learning. However, several challenges persist, including limited facilities, insufficient teacher training, and unequal access to technology in certain regions. To ensure the sustainability of STEM implementation, strategies should include the development of a flexible curriculum, intensive training for teachers, and collaboration with industry and private sectors. This study underscores that, with proper management, STEM-based learning holds significant potential to improve the quality of education in Indonesia, particularly at the high school level, and to prepare students for the challenges of the modern era. The findings of this study are expected to serve as a reference for designing more innovative and inclusive educational policies and practices.       Keywords: implementation, STEM, high school, indonesia, literature review.DOI: http://dx.doi.org/10.23960/jpmipa/v25i3.pp1428-1443

Abstract

Understanding the concept of physics students can not be achieved through lectures alone, but required practicum. However, limited equipment makes practicum difficult to do as an example of atomic spectroscopy. However, the use of information technology-based media in the form of virtual laboratories can be used as an alternative choice without losing its essence to facilitate Science Process Skills (SPS). This study aims to compare the improvement of students' SPS in atomic spectroscopy practicum using Advance Physics Virtual Laboratory (ADPHYLAB) and LABSTER. This research is a modified type of comparative research. The research time was conducted for 3 meetings, located in the Physics Laboratory of FKIP UNTIRTA. The research subjects were 8 physics laboratory assistants. The results showed that the SPS N-Gain score in the group using ADPHYLAB obtained consecutive values for classification, measurement, data interpretation and inferring indicators of 0.73; 0.89; 0.71 and 0.94, falling into the high category. While the group using LABSTER obtained scores on classification and measurement indicators of 0.40 and 0.53, falling into the medium category. While in the data interpretation and inferring indicators of 0.79 and 0.80 fall into the high category. Based on the results of the study, it can be concluded that ADPHYLAB-based learning media can improve student SPS compared to LABSTER-based learning media.         Keywords: ADPHYLAB, virtual laboratory, LABSTER, science process skills, atomic spectroscopy. DOI: http://dx.doi.org/10.23960/jpmipa/v25i2.pp932-945

Abstract

The skills involved in the mathematical thinking process are crucial for university students pursuing Mathematics Education. However, most of them lack proficiency in seeing patterns while addressing an issue and articulating the problem in mathematical terms. The objectives of this research are (1) to analyze students' mathematical thinking process skills; (2) to ascertain students' expectations regarding the learning process and assessment in Ethnomathematical education; (3) to develop a performance assessment model design; (4) to evaluate the quality of the performance assessment model within Ethnomathematics-based Project-based Learning (PjBL) for measuring students' mathematical thinking process skills; and (5) to report the outcomes of measuring students' mathematical thinking process skills. This study employs a research and development (R&D) design. This study's population comprises all 6th-semester students enrolled in the Mathematics Education program at Muria Kudus University. The research sample was obtained by a saturation sampling procedure, comprising 107 students. The study instruments employed consist of assessment tools designed to evaluate students' mathematics cognitive processing skills. The acquired data were analyzed descriptively. The research findings indicate that: (1) students' mathematical thinking process skills are suboptimal, with a mean value of 54.14%; (2) students desire greater engagement in an active learning process that connects to real-life situations and cultural contexts, incorporating assessments that reflect individual performance; (3) a performance assessment model design for Ethnomathematics-based Project-Based Learning (PjBL) has been developed, encompassing objectives, components, instruments, syntax, and model guidelines. The created performance assessment approach for ethnomathematics-based project-based learning is both valid and reliable, and the evaluation of mathematical thinking process abilities demonstrates exceptional outcomes. This study suggests the necessity of implementing the ethnomathematics-based Project-Based Learning (PJBL) performance evaluation model to enhance students' mathematical thinking skills through an active, contextual, and culturally relevant method.         Keywords: ethnomathematics, performance assessment, pjbl, project-based learning.DOI: http://dx.doi.org/10.23960/jpmipa/v25i3.pp1281-1296
