<![CDATA[Based on scientific studies that have been conducted, data shows that the achievement of Indonesian students in the numeracy aspect is low. This study aims to improve students' numeracy skills through the utilization of origami paper media in the learning process. The type of research is descriptive qualitative. The subjects in this study were 5th grade students at SDN Alastlogo 1 Lekok, Pasuruan Regency, totaling 25 people. The instruments used were the Minimum Competency Assessment (AKM) pretest and posttest sheets and field notes. The source of data in this study came from the results of the pretest and posttest of the Minimum Competency Assessment (AKM Class). The data collection technique used is to carry out the AKM Pretest. Then make a learning strategy for flat building material using origami media to students. After that, the Class AKM Posttest was conducted as a student evaluation. The data analysis technique used is comparative analysis. In addition, analyzing each learning process using folding paper or origami media, to determine the effectiveness of learning implemented in the study. The results of this study show that there is an increase in students' numeracy skills by 80%. Students can answer correctly from the flat building questions tested on the AKM Posttest, whereas previously in the AKM Pretest, only 20% of students could answer correctly. This proves that folding paper or origami media is very effective to help improve students' numeracy skills regarding flat shapes.]]>

<![CDATA[Mathematics remediation (MR) is crucial in higher education, serving as a cornerstone to prepare under-equipped students. However, numerous Mathematics Education students in one of the public universities in Indonesia have repeatedly failed in this program. Failure experiences have an essential role in pre-service mathematics teachers' personal and professional development. While some research has explored the students' failure experiences, a significant gap exists in exploring the perception of repeatedly failed students in MR. Our qualitative narrative case study delves into the perceptions of repeatedly failing students regarding the MR and their failures. Five themes emerged through analysis of reflective writing and interview data: perceptions of mathematics and its learning, perspectives on the MR program, attitudes toward failure, factors contributing to participant failures, and expectations for MR program development. This study provides valuable insights to enhance the effectiveness of MR, shedding light on the intricate dynamics surrounding students' experiences with the program.]]>

<![CDATA[It is necessary to emphasize the ability to conceptual understanding of geometry (CUG) for each student to support the formation of mathematical competence. In forming, it is important to carry out a lesson by prioritizing interaction between students in conveying ideas known as sociomathematical norms. The construction CUG is very important for learning by prioritizing interaction between students in conveying ideas known as socimathematical norms. The aims of study to analyze the implementation of the discovery learning (DLM) in developing achievements of CUG based on aspects of socio mathematical norms in learning plane geometry. This study used a quasi-experimental method by following a nonequivalent control group design. The sample involved in this research was 70 students of the mathematics education study program. This study concludes: 1) Achievement of students' CUG by implementing DLM is better than achievement of students' CUG by applying the conventional model (CM). 2) there is are significant differences between the achievement of students' CUG using DLM and students applying CM based on the socio mathematical norm level; 3) there is an interaction effect between DLM and sociomathematical norm factors on achievement of students' CUG; 4) the contribution of DLM implementation to student CUG achievement includes: (a) Student Worksheets with DLM syntax make it easier for students to deepen geometry material; (b) a discussion process that gives rise to students' freedom of expression; (c) the diversity of alternative problem solving strengthens students in determining the best choice and analysis of problem solving; (d) classical presentation activities motivate students to understand the concepts in each lesson.]]>

<![CDATA[The aim of this research was to find out how prospective mathematics teachers can visualize the form of fractional division operations based on mathematical literacy skills. This research includes qualitative research with descriptive methods. This study was conducted on 3 students of the 3rd semester mathematics education program with high, medium and low mathematical ability with good communication skills. Researchers gave three questions on literacy tests. The tests given include problems related to division of integers by fractions, division of fractional numbers by integers and division of fractional numbers by fractional numbers. From the test results obtained, interviews were conducted of all three subjects. The results showed that all three subjects were able to understand and translate the questions and formulate what was asked of the questions. However all three subjects encountered constraints when trying to visualize the form of division of fractions by fractional numbers. They just memorize division formulas like “multiplying and inverting”. From the results of the data analysis, it can be concluded that the literacy ability of the subject in visualizing the form of the division operation is still classified as low.Keywords : Mathematical Literacy, Visualizing, Divison of Fraction. ]]>
