This study aims to develop and test the feasibility of a Problem-Based Learning (PBL)-based Sequence and Series teaching module in facilitating the mathematical problem-solving abilities of Phase E students. This type of research is development research (Research and Development) that uses the ADDIE model, which includes five stages: Analysis, Design, Development, Implementation, and Evaluation. In the analysis stage, observations and interviews were conducted with teachers and students at SMA Negeri 10 Pekanbaru to identify needs and problems in mathematics learning. The design stage focused on compiling a module based on PBL syntax, including problem orientation, student organization, investigation, development of work results, and evaluation and reflection. The developed module was validated by two Mathematics Education lecturers and one mathematics teacher to assess aspects of content, construction, language, and appearance. The validation results showed a validity level of 94% with a very valid category, while the practicality test results showed a value of 87% with a very practical category. Data collection techniques in this study included interviews, observations, questionnaires, and documentation. Data analysis related to validity and practicality was carried out using a percentage formula. These findings indicate that the developed teaching module is feasible and effective for mathematics instruction, particularly in improving students' problem-solving abilities. Therefore, this PBL-based teaching module can serve as an innovative learning tool that aligns with the principles of the Merdeka Curriculum and fosters students' critical, creative, and reflective thinking skills.

Mathematical understanding is a fundamental component of mathematics learning, as it underpins the development of other essential mathematical competencies. However, many students tend to rely on memorizing formulas without achieving a deep conceptual understanding. This study aimed to analyze students’ mathematical understanding in the topic of three-dimensional shapes with flat surfaces at the junior high school level. A descriptive qualitative approach was employed, involving 25 students from SMP Negeri 12 Pekanbaru as research participants. Data were collected through two open-ended test items and semi-structured interviews, and analyzed using indicators of mathematical understanding, including restating concepts, applying procedures algorithmically, and connecting concepts within and beyond mathematics. The results showed that the majority of students (76%) demonstrated a low level of mathematical understanding, while 12% were classified as having moderate understanding and 12% as having high understanding. Students in the high category were able to fulfill all indicators, whereas those in the moderate and low categories experienced difficulties, particularly in applying procedures algorithmically and establishing conceptual connections. These findings indicate the need for instructional practices that emphasize conceptual understanding and support students in meaningfully connecting mathematical concepts to problem-solving contexts.

This study aims to improve the mathematical communication skills of students in class IX-6 at SMP Negeri 3 Mandau through the implementation of the Problem Based Learning model on the topics of congruence and similarity. Based on interviews and observations, it was found that students faced difficulties in understanding problems, explaining mathematical ideas, and presenting mathematical models. This classroom action research was conducted in two cycles, with each cycle consisting of planning, implementation, observation, and reflection. The data collected included qualitative and quantitative data, which were analyzed to evaluate the improvement in students' mathematical communication skills. The results of the study indicate that the implementation of the Problem Based Learning model successfully enhanced student engagement and mathematical communication skills. The average KKM score of students increased from 31 in the initial test to 63 in cycle I, and reached 90 in cycle II. This improvement demonstrates that the Problem Based Learning model is effective in enhancing the learning process and improving students mathematical communication skills. Therefore, it can be concluded that the application of the Problem Based Learning model on the topics of congruence and similarity can enhance the quality of mathematics education in class IX-6 at SMP Negeri 3 Mandau.
