Learning geometric transformations often presents challenges for students due to their abstract nature and limited connection to real-world contexts. Reflection is one of the most difficult concepts for students to understand. This study aims to design a Hypothetical Learning Trajectory (HLT) for geometric reflection using the PMRI approach through the context of Batik Jambi. This research employed a design research approach in the preliminary design phase, with data co llected through teacher interviews and literature studies. The result is a five-stage HLT design that utilizes the Bungo Melati motif as a symmetry context, guiding students from concrete experiences toward formal understanding through progressive mathematization. The findings indicate that incorporating the Batik Jambi context can enhance students’ comprehension of reflection while also connecting mathematics learning with local cultural values. This HLT design has the potential to serve as a foundation for developing a Local Instructional Theory (LIT) for more meaningful and contextualized geometry learning.

Statistical literacy is a critical competence for 21st-century students, yet many struggle to apply statistical concepts in authentic contexts. This study reports the development of JUMPISA, a PISA-based Jumping Task contextualized for secondary students in Jambi Province, designed to enhance students’ abilities to interpret, represent, and reason with data. Employing a design research approach with iterative development, the study included preliminary and formative evaluations to assess task validity and feasibility. The JUMPISA tasks integrate content on uncertainty, work-related contexts, and varying reasoning levels in line with PISA’s framework. Results indicate that students demonstrated notable improvement in engaging with authentic statistical problems. Beyond practical effectiveness, this study advances the theoretical understanding of context-sensitive PISA Task design, showing how locally contextualized, inquiry-driven tasks can be systematically developed and validated for international assessment. JUMPISA exemplifies a model for aligning global assessment frameworks with local educational contexts, offering guidance for both researchers and practitioners in designing assessment-informed instructional activities.

This research is motivated by the lack of technology integration in learning which results in students having difficulty understanding the material, and leads to low learning outcomes. An innovation is needed to support the learning process which is expected to improve student learning outcomes. Therefore, the purpose of this study is to develop and assess the quality of learning media in the form of animated videos using the STEAM-based Canva application to improve student learning outcomes in the Enumeration Rules material. This research is a type of R&D development research with the ADDIE model, which consists of five stages: analysis, design, development, implementation, and evaluation. The research subjects included one mathematics teacher and 35 students of class XI F1 of SMA Negeri 8 Muaro Jambi. The results showed that the developed media met the criteria of validity, practicality, and effectiveness. In terms of validation, the percentage of material feasibility reached 91.7% and the design reached 87.5%, which is classified as very valid. Meanwhile, the practicality of implementation , the teacher gave an assessment of 92% and students 90.9% which is also included in the very practical category. Meanwhile, the implementation of media effectiveness is seen from the student response questionnaire , which obtained a score of 88.42% in the very effective category. The results of the average difference test of student learning outcomes showed that the posttest score was better than the pretest score . The comparison results of the average N-Gain score of 0.65 with a percentage of 65% which is included in the fairly effective category. Thus, the STEAM-based animated video learning media using Canva is declared suitable for use in the learning process on the Enumeration Rules material for grade XI SMA because it meets the criteria of validity, practicality, and effectiveness.

This study aims to describe students' critical thinking skills in solving mathematical problems, particularly in geometry. The indicators used refer to Facione’s framework, which includes interpreting, analyzing, applying, evaluating, and concluding. This research employs a qualitative descriptive method with ninth-grade students as the research subjects. Data were obtained from students’ written test results and supported by interviews to explore their reasoning processes. The findings reveal that students’ critical thinking skills remain relatively low, especially in evaluation and conclusion. Most students can interpret and apply concepts but have difficulty analyzing problems deeply or verifying their solutions. These results indicate the need to develop innovative teaching materials and learning strategies to enhance students’ critical thinking skills.

Mathematical literacy is essential for preparing students to solve real-world problems, yet the cognitive processes underlying context-based problem solving remain insufficiently understood. In the PISA framework, mathematical literacy involves the ability to formulate, employ, and interpret mathematics in meaningful contexts. Previous studies have focused primarily on outcomes rather than the processes involved, particularly within local cultural settings such as Jambi. Given the persistent underperformance of Indonesian students in PISA, examining mathematical literacy in a local context is important. This study aimed to analyze students’ mathematical literacy processes using Jambi-based contextual tasks. A qualitative descriptive design was employed involving 24 seventh-grade students selected through purposive sampling to represent high, moderate, and low ability levels. Data were collected through PISA-like written tests and semi-structured interviews and analyzed based on the processes of formulate, employ, and interpret/evaluate. The results showed that 68.06% of students were able to formulate problems, 52.78% successfully employed appropriate mathematical procedures, and only 34.72% correctly interpreted and evaluated solutions. These findings indicate that students experience the greatest difficulty in connecting mathematical results to real-life situations. The research process-oriented assessment and culturally contextualized tasks strengthen students’ interpretative and evaluative competencies in mathematical literacy.

This research seeks to create legitimate and practical teaching materials in the form of a module utilizing a realistic mathematics education approach focused on the topic of systems of linear equations in two variables. This study utilizes the research and development (RD) approach, specifically the Thiagarajan 4-D model, which consists of four stages: (1) definition, (2) design, (3) development, and (4) dissemination. We conducted the research at MTsN 1 Central Aceh. Two classes, each with high and moderate abilities, participated in the research. The trial analysis yielded the following findings: (1) Validity, as two experts validated the teaching materials; (2) Practicality, as demonstrated by an average implementation of the learning syntax exceeding 75%, an average student activity exceeding 75%, extremely positive student and teacher responses to the module, and a classification of the developed module as practical. According to the results of the students' learning tests, 15 students completed the requirements out of 19 students in the high-ability class, and 14 students completed the requirements out of 19 students in the medium-ability class. Consequently, we categorize the percentage of students who have met the requirements as excellent. The module created utilizing a realistic mathematics education technique for the topic of systems of linear equations in two variables for eighth grade is deemed viable, indicating it is both valid and practical.
