This study aims to develop a product in the form of a mathematics teaching module based on the Problem-Based Learning (PBL) model to enhance students' mathematical communication skills in the context of linear equations and inequalities with one variable for Grade VII students in junior high schools (SMP/MTs). The study evaluates the teaching module's validity, practicality, and effectiveness. Additionally, the findings of this research can serve as a reference for teachers in designing teaching modules that improve communication skills in other mathematical topics and as a resource for students to practice and enhance their communication skills. This research is based on the importance of mathematical communication skills for students. According to the Ministry of National Education, one of the objectives of mathematics learning is to enable students to communicate their ideas through symbols, tables, diagrams, or other representations. However, field observations show that the reality is quite the opposite. The mathematical communication skills of Grade VII students (Phase D) in junior high schools are still relatively low, particularly in linear equations and inequalities with one variable. One of the indicators of this issue is that students do not create mathematical symbols accurately when solving problems. While they can solve problems presented in a format like the teacher's examples, they struggle with different problem formats, especially word problems, which are confusing. The data collection instruments used in this study include validation and practicality instruments. The data collection techniques involve interviews, questionnaires, and mathematical communication skill tests. The data analysis techniques employed are both quantitative and qualitative analyses. The development of the teaching module in this research follows the 4-D model (Four-D Model), which consists of four stages: defining, designing, developing, and disseminating.

Mathematical reasoning ability is an essential competency emphasized in the Merdeka Curriculum, particularly in the Learning Outcomes (CP) for Phase E, which requires students to understand, generalize, and prove mathematical concepts. However, various studies have shown that Indonesian students' mathematical reasoning skills remain relatively low, including in the topic of sequences and series. This study aims to analyze students’ errors in solving mathematical reasoning problems related to sequences and series in Grade 10, based on Nolting’s error theory. The research employed a qualitative descriptive approach involving 20 tenth-grade students from Senior High School 12 Pekanbaru. The research instrument consisted of four mathematical reasoning essay questions covering arithmetic and geometric sequences and series, adapted from Fadillah. The analysis revealed four types of student errors: Careless Errors (34.30%), Connection Errors (31.20%), Test-Taking Errors (21.80%), and Application Errors (17.50%). These errors were attributed to various factors, including cognitive factors such as lack of conceptual understanding and affective factors such as low learning motivation. The findings highlight the importance of teachers in analyzing student errors to help minimize learning difficulties in mathematics and improve the overall quality of mathematics instruction

This research aims to develop discovery learning-based teaching materials on quadratic functions to improve mathematical representation abilities of grade X students. The low mathematical representation ability of Indonesian students reflected in TIMSS 2015 results is the research background. Research and Development (R&D) methodology with a 4D model (Define, Design, Develop, Disseminate) was used to develop the learning product. Validation was conducted by three mathematics education experts, practicality testing through student response questionnaires, and effectiveness was measured using a Post-test Only Control Group design comparing experimental and control classes. The findings showed very high validity at 91.54%, practicality reached 79.31% in the practical category, and significant effectiveness demonstrated through average score increase from 73.27 to 83.20 (sig = 0.000 < 0.05). The Z proportion test yielded 1.8974 > 1.645, indicating more than 75% of students achieved the minimum mastery standard. This teaching material successfully facilitates mathematical representation skill development through structured discovery activities, although visual representation aspects need further optimization. The discovery learning approach effectively optimizes students' knowledge construction through meaningful learning experiences while overcoming conventional learning limitations in developing mathematical representation competencies
