Purpose: This study aims to develop a mathematics learning video based on the Indonesian Realistic Mathematics Education (IRME) approach by integrating the local cultural context of Jumputan Gambo fabric to support sixth-grade elementary students’ understanding of mixed arithmetic operations. Method: This research employed a development research design using the Rowntree model, which consists of planning, development, and evaluation stages. The evaluation stage was conducted using Tessmer’s formative evaluation framework, including self-evaluation, expert review, one-to-one evaluation, small group evaluation, and field testing. Four expert validators assessed the developed learning video in terms of media design, content accuracy, language clarity, and instructional design. Practicality data were obtained through student response questionnaires, while effectiveness was measured using pretest and posttest assessments. The collected data were analyzed using descriptive statistics and normalized gain (N-Gain). Findings: The results indicate that the developed learning video met the criteria of validity, practicality, and effectiveness. Expert validation showed a very valid category with an average score of 92.85%. Practicality results from the one-to-one and small group trials ranged from 92.22% to 100%. The effectiveness test demonstrated an improvement in students’ learning outcomes, with the average score increasing from 56.77 on the pretest to 85.48 on the posttest. The N-Gain value of 0.70 indicates a high level of learning improvement. Significance: The study demonstrates that integrating IRME principles with culturally contextualized video learning supports meaningful mathematics learning and provides practical guidance for teachers in designing contextual mathematics instruction aligned with the Merdeka Curriculum.

This study aims to describe students’ perceptions of the use of a role-playing game (RPG), Arithmetic Adventure: The Mystery of Polaria Village, in mathematics learning on arithmetic sequences and series. A quantitative descriptive research design was employed, involving 34 tenth-grade students at SMA Negeri 10 Palembang selected through purposive sampling based on their participation in RPG-based learning activities. Data were collected using a closed-ended Likert-scale questionnaire covering four aspects: motivation and engagement, perceived learning effectiveness, social interaction and collaboration, and challenges encountered during learning. Content validity was established through expert judgment, while instrument reliability was confirmed using Cronbach’s Alpha coefficients ranging from 0.77 to 0.91, indicating acceptable to excellent internal consistency. Descriptive analysis showed that students perceived the RPG positively in terms of motivation, engagement, and learning effectiveness, while challenges related to technical constraints and game complexity were reported at a moderate level. The integration of narrative-based gameplay with mathematical thinking stages—specializing, generalizing, conjecturing, and convincing—was perceived as supporting students’ reasoning and problem-solving processes. These findings suggest that RPG-based learning can serve as a meaningful and engaging instructional medium in mathematics, although its implementation requires careful design considerations and adequate technical support.

Despite the growing use of interactive multimedia and game-based learning in mathematics education, educational escape room games specifically designed for teaching number patterns in elementary schools remain limited and are rarely developed based on comprehensive needs analyses. This study aimed to analyze the need for developing interactive multimedia in the form of an educational escape room game for fifth-grade elementary school students. A descriptive quantitative survey was conducted involving 55 fifth-grade students and 10 teachers at SD Negeri 19 Talang Kelapa. Data were collected using validated Likert-scale questionnaires covering four aspects: teacher needs, student characteristics, learning media, and instructional design. The findings revealed that teacher needs were categorized as needed (73.2%), student characteristics as highly needed (82.4%), learning media as highly needed (87.1%), and instructional design as needed (61.7%). The learning media aspect showed the highest level of need, indicating the importance of engaging, interactive, and accessible digital resources to support mathematics learning. The proposed innovation emerging from this study is the integration of educational escape room game elements into interactive multimedia for number pattern instruction. These findings provide empirical evidence and practical guidance for developing interactive multimedia that aligns with students’ learning characteristics, teachers’ instructional needs, and effective instructional design principles. Future research is recommended to develop, implement, and evaluate the effectiveness of the proposed multimedia in improving students’ mathematical understanding and problem-solving skills.

In solving problems regarding linear programs, errors are often found, especially in determining feasible areas and optimum solutions. This research aims to analyze student errors in solving linear program problems using the LKPD-based Newman’s Error Analysis approach in the context of optimizing pempek production. This research used a qualitative descriptive method with the research subjects of three class X high school students selected based on test results. The instruments used are LKPDs that have gone through an expert validation stage (expert review) and problem-solving tests. Data analysis is carried out through data reduction, data presentation, and drawing conclusions based on Newman’s five stages, namely reading, comprehension, transformation, process skills, and encoding. The research results show that the most dominant errors occurred at the encoding stage, while process skills errors were only found in one research subject. These findings show that students still have difficulty understanding the concept of feasible regions and determining optimum solutions to linear programming problems. This research contributes as a basis for developing contextual LKPD-based linear programming learning and as evaluation material for teachers to get students used to writing complete and precise mathematical conclusions in solving linear programming problems. This research is expected to be the basis for designing more effective learning to minimize student errors.
