The ability to solve mathematical problems is an ability that needs to be mastered by students. However, in fact the ability of students' mathematical problem solving is relatively low. This is caused by one of them using inappropriate learning media. Therefore we need learning media that can help students to practice their mathematical problem solving abilities. The media in question is digital comics based on realistic mathematics education (RME). So the purpose of this study was to look at the effect of digital comics based on realistic mathematics education (RME) on students' mathematical problem solving abilities. The research method used is a quasi-experimental method using The Pretest-Posttest Non-Equivalent Control Group design. The results of statistical analysis obtained Sig. (2-tailed) in the output equal variances not assumed 0.000, where the value of Sig. (2-tailed) obtained is less than 0.05 or it can be said that 0.000 <0.05. So, based on the decision-making results of the analysis of this hypothesis test, it can be concluded that if "Significant level <0.05, then is rejected". It can be concluded that is accepted or it can be said that from the results of this analysis it can be concluded that there is an effect of digital comics based on realistic mathematics education (RME) on students' mathematical problem solving abilities

The learning process that is carried out optimally is a learning process that involves students actively. One of the learning approaches that can actively involve students is the contextual approach or Contextual Teaching & Learning (CTL). This qualitative research aims to determine students' activities during the implementation of CTL principles with GeoGebra assisted in a cartesius coordinate system at SMP Negeri 9 Palembang. The subjects were four students of VIII.3 SMP Negeri 9 Palembang. Data was collected online using observation sheets, questionnaires, interviews, & analyzed descriptively. From this research, it is concluded that the principles of CTL that appear in GeoGebra-assisted mathematics learning were constructivism, inquiry, modeling, authentic assessment, & learning community. Then the CTL principles that rarely appear during learning were questioning, & reflection.

The growing use of digital learning media in mathematics classrooms has not been matched by sufficient evidence of students’ mathematical reasoning (MR) when solving mathematical literacy problems. This study aims to analyze the MR of junior high school students at different MR levels while solving mathematical literacy problems on systems of linear equations in two variables (SLETV) in a learning context supported by a mathematical literacy-based e-module. Using a descriptive qualitative design, the study involved ninth-grade students from a public junior high school in Palembang, South Sumatra, Indonesia. Data were obtained through three written mathematical literacy problems and follow-up semi-structured interviews and then analyzed using three MR indicators: finding patterns of relationships and generalizing a statement, proposing conjecture, and verifying the truth of an argument. The results reveal that students’ MR remains limited, with only a small proportion demonstrating medium to high-level reasoning. High-reasoning students are already capable of demonstrating all indicators of MR, but low-reasoning students struggle to develop mathematical models from contextual problems. These findings suggest that e-module-assisted learning can support reasoning, but students at lower reasoning levels still require more explicit scaffolding, particularly for modeling, conjecturing, and justification.

The importance of ethnomathematics lies in its ability to integrate local cultural contexts into mathematics instruction, thereby facilitating a deeper and more relevant understanding of concepts for students. This research aims to train teachers to develop ethnomathematics-based mathematics learning that integrates local wisdom into the learning process. The approach used is participatory-collaborative, in which partners are not only beneficiaries but also actively participate in planning and implementing activities. The partners in this activity are junior high school mathematics teachers in Ilir Timur I District, Palembang City, who are under the auspices of the Palembang City MGMP. The results of this activity show that the ethnomathematics-based approach makes learning more interesting, easier to understand, and relevant to daily life. These results are also supported by the questionnaires distributed, which show that 92.33% are very satisfied with this activity. This activity is expected to be the initial step for teachers to continue developing contextual and local wisdom-based innovations in mathematics learning.

This study was motivated by students’ low reasoning ability, which stem from a monotonous learning process that results in a lack of thinking activities, causing students to be passive or disengaged, as well as a lack of engaging and interactive learning media. Reasoning is an essential skill because it is one of the primary focuses of the Indonesian education curriculum. Reasoning involves the logical thinking process of gathering facts, analyzing them, and drawing conclusions. Based on this background, this study aims to describe students’ mathematical reasoning ability using the RME approach supported by Scratch. The RME approach emphasizes the use of real-world contexts; in this case, the researcher uses the context of grilled Kemplang, which is closely related to the subjects’ daily lives. The novelty of this study lies in the application of RME supported by Scratch using the context of grilled Kemplang. This is a qualitative descriptive study with 34 seventh-grade students as the research subjects; then, using purposive sampling, 3 students were selected as representatives of the categories of students’ mathematical reasoning abilities. Data were collected through observation, written tests to be analyzed based on scoring guidelines, and interviews to be transcribed and subsequently described. The results of the study indicate that after instruction using the RME approach with Scratch as a learning medium, students’ mathematical reasoning ability fell into the moderate category. Thus, instructional activities using the RME approach are effective in improving students’ mathematical reasoning ability and their active engagement in the learning process.
