(During the learning process, the use of media and teaching materials, as well as non-routine questions, can help students improve their understanding and literacy in mathematics. One of them is game-based media designed or created to stimulate thinking skills to improve concentration and problem-solving, with attractive features such as audio, text, images, and moving animations, utilizing only links and tools on each individual's Android phone. This is also in line with the use of technology-based media in learning as formulated by the Ministry of Education and Culture through the Merdeka Curriculum. This research aims to produce valid and practical educational math game materials in the form of an Android-based game and to describe students' responses after using the game. The subjects of this research are 33 seventh-grade students from SMP SRIJAYA Palembang. The research method used is Development Research, with the model applied in the learning process being the Plomp model, which consists of 2 stages: preliminary research and prototyping. The data collection techniques are questionnaires, observations, interviews, and tests. The questionnaire is used to assess the validity and practicality of the teaching materials. Observation is used to measure learning effectiveness, while tests are used to measure students' mathematical literacy.

STEAM is one of the learning approaches that can be used to support students' understanding and knowledge of science, technology, engineering, art, and mathematics can increase, so that this understanding can be used to solve problems and make decisions for the progress of students. However, STEAM is still underutilized in schools. The purpose of this survey research is to describe students' perceptions of learning mathematics using STEAM. The participants in this study were 90 grade 9 students at SMP Negeri 13 Palembang. Participants were selected using voluntary and random sampling techniques. Data were collected using a questionnaire consisting of two parts, namely closed and open statements. Data were analyzed using descriptive statistics with qualitative methods. The results showed that students gave positive and negative responses to the application of STEAM in learning. Students agree that STEAM can increase their motivation and activity in learning. On the other hand, some students choose to apply learning without media because they prefer learning directly delivered by the teacher. This contributes to students' difficulties in mastering math concepts. The results of this study provide useful insights for future research in learning approaches used in teaching.

Geometry is a fundamental branch of mathematics that supports the development of logical thinking, spatial reasoning, and problem-solving skills. Yet, many students still struggle to understand geometric concepts because learning remains abstract and lacks meaningful real-world connections. In Indonesia, geometry instruction often emphasizes procedural mastery over deep conceptual understanding, underscoring the need for innovative approaches that make learning more concrete and engaging. Integrating real-world contexts, the STEAM (Science, Technology, Engineering, Arts, and Mathematics) approach, and Virtual Reality (VR) technology offers a promising way to bridge the gap between abstract ideas and practical applications. This study investigates the extent of implementation and the challenges in applying contextual, STEAM-based, and VR-supported geometry learning in Indonesia. Participants included 100 junior high school students and 10 mathematics teachers, randomly selected from South Sumatera, a region whose Gambo Muba textile tradition provides a culturally relevant context for geometry learning. Using a mixed-methods design, data were collected through questionnaires, interviews, and classroom observations. Findings show that STEAM-based and VR-supported learning positively influences students’ conceptual understanding, motivation, and engagement, particularly in geometric transformations. However, implementation remains at an early stage, with teachers displaying positive attitudes but limited experience, and with constraints on VR availability and training. The study underscores the need for capacity building and improved infrastructure to optimize this innovative approach.

This study addressed students’ difficulties in understanding the median as a conceptual measure of central tendency rather than a procedural computation. It aimed to design and validate a STEM-based learning trajectory to support students’ understanding of the median through coffee pH measurement activities. The study employed a design research methodology of the validation study type, consisting of a preliminary design, pilot experiment, teaching experiment, and retrospective analysis. The subjects were tenth-grade vocational high school students in Palembang majoring in culinary arts. Data were collected through classroom observations, student worksheets, semi-structured interviews, and video recordings. The results showed that the STEM-based learning trajectory enabled students to progress from concrete data collection to data organization, identification of the middle position, formal median calculation, and contextual interpretation. The instructional design can support students’ conceptual understanding. A STEM-based learning trajectory using the context of coffee pH measurement can serve as an alternative instructional strategy to help students gradually develop a conceptual understanding of the median while simultaneously enhancing statistical literacy through authentic experiences of collecting, processing, and interpreting data.

Character education plays an important role in shaping individuals who not only excel academically but also possess strong morals and high social values. In the context of mathematics learning, character values not only help students understand numerical concepts but also instill discipline, hard work, and perseverance. This study aims to analyze the implementation of character values in mathematics learning and the role of teachers in developing them. The subjects of the study were 100 high school students from public schools in Palembang. Data were collected through questionnaires and interviews and analyzed using descriptive methods. The results showed that the values of discipline, hard work, and religiosity were dominant, while creativity and communication remained weak. Therefore, efforts are needed to develop these values, particularly creativity and communication, through improved teacher professionalism, interactive learning, integration of real-world contexts, and addressing students' psychological barriers.

The linear equation is a fundamental mathematics topic that often poses significant challenges for students. These difficulties are primarily due to traditional teaching methods that emphasize memorization of formulas over deep understanding, coupled with insufficient focus on developing reasoning and problem-solving skills. This study seeks to develop a learning trajectory for teaching linear equations using the Rigorous Mathematical Thinking (RMT) approach, aiming to enhance students' relational understanding. The research was conducted using a design research method, which involved creating and refining a learning trajectory through preliminary design, experimental implementation, and retrospective analysis, all conducted over two cycles. Participants included 8th-grade students from a junior high school in Palembang, with 32 students in class 8.2 participating in the pilot experiment and 36 students in class 8.1 in the teaching experiment, selected through purposive sampling. Data collection methods included observations, written tests, and interviews, with qualitative analysis used to present the findings in a narrative format. The study resulted in the development of a learning trajectory that effectively supports students' relational understanding of linear equations. The learning process encouraged students to draw on their existing knowledge, identify the most efficient and effective strategies, provide detailed solutions, and gain confidence in the accuracy of their answers while solving problems related to the equation of a line through two points and the equation of a line perpendicular to another line.
