This study aims to describe students' mathematical literacy skills reviewed from problem-solving skills in solving AKM-shaped questions. The method of this research is a qualitative descriptive study. This study was conducted in class 10 MAN 3 Jakarta Pusat and took 251 students as respondents. Data collection in this study was carried out by conducting problem-solving tests, mathematical literacy tests, and interviews. Based on the level of mathematics literacy achievement, students are grouped into 4 levels, namely, requiring special intervention, basic, professional, and advanced. While problem-solving skills are grouped into 3 categories, namely low, medium, and high. The results showed that most students, regardless of problem-solving skills category, were at “needing special intervention” level in mathematical literacy achievement. However, no students in the low problem-solving skills category reached the advanced level in mathematical literacy. Students often ignore the “looking back” step in problem solving. In fact, ignoring this step causes many students to make mistakes in the final results, including students with higher problem-solving skills. These results indicate the importance of teacher intervention in mathematics learning so that students are more careful and effective in solving problems.

Problem solving is a process that requires logical thinking to find solutions to the problems faced. Through this process, students will learn to develop appropriate strategies to solve the problems. This study aims to identify errors made by students in solving problems on the material of function derivatives. The method used in this study is descriptive qualitative, with data collection techniques carried out through previous literature reviews. The results of the study showed that students made mistakes at several stages, namely in understanding the problem, designing a solution strategy, implementing the solution, and at the re-checking stage. Based on the type of error, students made mistakes in terms of facts, concepts, principles, and operations. The proposed solution is to accustom students to be more careful in solving problems based on problem-solving steps, especially at the final checking stage, and to improve their mastery of algebraic operations and basic factoring techniques.

ABSTRACT Mathematical problem-solving skills are an important competency in the 21st century, but it is still a challenge for junior high school students due to the low active involvement of students in the learning process and the limitations of conventional learning media that do not support critical and exploratory thinking processes. This study aims to test the effectiveness of discovery-based interactive learning media in improving the mathematical problem-solving ability of grade VIII junior high school students. This study uses a quantitative method with a one group pretest-posttest design. The subjects of the study were grade VIII students in one of the junior high schools in Yogyakarta who were selected purposively. The research instruments were in the form of mathematical problem-solving ability tests and media implementation observation sheets. Data analysis was carried out using a paired sample t-test with the help of SPSS 25. The results showed a significant increase in mathematical problem-solving ability after the use of learning media, with an average difference in pretest and posttest scores of 31.806 points and a significance value of 0.000 (p < 0.05). All mathematical problem-solving indicators improved, with the "understanding the problem" indicator showing the highest improvement. This shows that discovery-based interactive learning media is able to support students in building conceptual understanding from the early stages of problem solving. It can be concluded that interactive learning media based on discovery learning is effectively used to improve the mathematical problem-solving skills of junior high school students. The implication of this study is the need to develop and apply interactive learning media based on a constructivist approach more broadly in mathematics learning.

Mathematical communication ability is a key component of overall mathematical proficiency. Enhancing this skill can be achieved through the application of an effective learning model. The RADEC learning model serves as a promising method to boost students’ mathematical communication capabilities. This study seeks to examine the differences in mathematical communication skills between an experimental group taught using the RADEC model and a control group, as well as to evaluate the model’s effectiveness in fostering these skills. Employing a quantitative approach with a true experimental design and a pretest-posttest control group setup, the research was carried out in a school located in Mojokerto City, involving class XE1 as the experimental group and XE2 as the control. Data were gathered via tests and observations, utilizing instruments such as mathematical communication skill assessments and observation checklists for RADEC implementation. The data were analyzed through descriptive and inferential statistical methods. Findings indicated a notable difference between the experimental and control groups, with mean scores of 31.4 and 21.3 respectively. The Mann-Whitney U test showed a significance value of 0.000 (p < 0.05), confirming the difference was statistically significant. Furthermore, the N-Gain analysis revealed that the improvement in mathematical communication skills was moderate. In summary, the RADEC learning model effectively enhances students’ ability to communicate mathematically.

Teaching English as a medium of instruction in South Africa remains a contentious issue. This research investigated the consequences of using English as a medium of instruction on the academic participation of grade 4 learners. In this instance, Bourdieu’s Theory of Practice was applicable as it considers how a learner's social background and identity influence their learning processes. The study was qualitative and framed within the case study design. Participants were five purposively sampled learners for the semi-structured interviews and 70 for the mathematics lesson observations. The collected data was analysed thematically. Learners could not follow basic English instructions, ask questions, communicate, discuss tasks, answer mathematically posed questions or participate in informal group discussions. The teachers used code-switching, the banking teaching method, and chalkboard and chalk as the materials and resources for teaching. Moreover, more than two learners used single textbooks. Thus, we propose the following: specialised English assistance programmes which improve learners' skills, interactive pedagogic approaches that enhance learners' involvement and participation in English lessons, and incorporation of multimedia, modern technologies and interactive devices to make learning more interesting and relevant, as well as enabling learners to work autonomously and at their own pace, so they can build their confidence towards using English. The Department of Education needs to reduce the size of classrooms for effective teaching and learning and to provide teachers with training on language teaching methods and techniques.

The differences in the characteristics of field dependent and field independent students in applying their mathematical literacy affect the results of students' work in solving mathematical problems. This study aims to identify students' mathematical literacy abilities viewed from cognitive style especially field dependent and field independent students in solving mathematical problems. This study uses a case study method with a qualitative approach which was carried out in one of the junior high schools in North Bengkulu Regency, Bengkulu Province, involving 32 students of class VIII in the 2022/2023 academic year who had studied number pattern material as participants. The subjects in this study were selected purposively, namely 3 students with a Field Dependent (FD) cognitive style. Data in the study were collected using the Group Embedded Figure Test (GEFT), mathematical literacy tests, and interviews. The research findings show that the majority of students have a cognitive style FI compared to FD. Most students achieved mathematical literacy skills at level 3. In terms of cognitive style, from the five levels of questions given, level 1-level 5, FD subjects with low, medium, and high initial mathematical abilities (KAM) achieved mathematical literacy up to level 3. The students met the formulate, employ and interpret indicators but still had difficulty writing mathematical symbols.

This study aims to explore the geometric concepts contained in Papuan cultural heritage and integrate them into mathematics learning. The main focus of this study is on three Papuan cultural heritages, namely the Honai traditional house, the Papuan Crown, and the Tifa. These three cultural artifacts not only have deep cultural value but also contain geometric principles that are relevant to mathematics learning. The method used in this study is qualitative research with an ethnographic approach, which involves direct observation and documentation. The data obtained is then analyzed using GeoGebra software to visualize and analyze the geometric shapes in the cultural heritage. The results of the study show that each Papuan cultural heritage contains geometric principles that can be used as examples in mathematics learning, as well as contributing to the development of ethnomathematics learning. The Honai Traditional House, with its circular base, tubular body, and conical roof, reflects the application of stable and efficient geometry. The Papuan crown, with a semicircular base and decorations that contain the principles of rotation, reflection, and dilation, demonstrates the application of symmetrical and harmonious geometry. The Tifa, which is cylindrical or tubular in shape with geometric elements in the form of circles at the top and decorations in the form of isosceles triangles, equilateral triangles, and kites, also reflects the application of significant geometric principles. This study recommends further development related to the application of GeoGebra in ethnomathematics learning and the development of ethnomathematics-based e-LKPD that highlights the cultural heritage of Papua. Thus, it is hoped that mathematics learning can become more contextual and relevant to local culture, as well as provide a more interactive and meaningful learning experience for students. Keywords: Ethnomathematics, GeoGebra, Geometry, Papuan Cultural Heritage.
