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.

This research investigates student errors in solving contextual problems involving Systems of Linear Equations in Three Variables (SPLTV) using Newman’s Error Analysis framework. The theory categorizes errors into five cognitive stages: reading, comprehension, transformation, process skills, and encoding. A qualitative descriptive method was applied, involving three 10th-grade vocational school students from different majors in Kampar Regency, selected based on varying ability levels. Data were collected through contextual written tests and interviews. Findings reveal that low-ability students made errors across all stages, medium-ability students primarily struggled with process skills and encoding, while high-ability students demonstrated minimal errors and systematic problem-solving. The highest error rates occurred in the reading and comprehension stages (33% each), followed by transformation, process skills, and encoding (22% each). These results highlight the crucial role of contextual understanding and mathematical modeling in SPLTV. The study recommends differentiated instruction and the integration of contextual problems to reduce errors and enhance students' mathematical thinking. Penelitian ini mengkaji kesalahan siswa dalam menyelesaikan soal kontekstual Sistem Persamaan Linear Tiga Variabel (SPLTV) dengan menggunakan kerangka Analisis Kesalahan Newman. Teori ini mengelompokkan kesalahan ke dalam lima tahapan kognitif, yaitu membaca, memahami, transformasi, keterampilan proses, dan penulisan jawaban. Metode deskriptif kualitatif diterapkan dengan melibatkan tiga siswa kelas X dari jurusan berbeda di salah satu SMK di Kabupaten Kampar, yang dipilih berdasarkan tingkat kemampuan yang bervariasi. Pengumpulan data dilakukan melalui tes tertulis berbentuk soal kontekstual dan wawancara. Hasil penelitian menunjukkan bahwa siswa berkemampuan rendah melakukan kesalahan pada seluruh tahapan, siswa berkemampuan sedang terutama mengalami kesalahan pada tahap keterampilan proses dan penulisan jawaban, sedangkan siswa berkemampuan tinggi menunjukkan kesalahan minimal dan mampu menyelesaikan soal secara sistematis. Persentase kesalahan tertinggi terjadi pada tahap membaca dan memahami (masing-masing 33%), diikuti oleh tahap transformasi, keterampilan proses, dan penulisan jawaban (masing-masing 22%). Temuan ini menegaskan pentingnya pemahaman konteks dan kemampuan pemodelan matematis dalam menyelesaikan SPLTV. Penelitian ini merekomendasikan penerapan pembelajaran diferensiatif serta integrasi soal kontekstual untuk mengurangi kesalahan dan meningkatkan kemampuan berpikir matematis siswa

This study examines how altruism and teacher self-efficacy influence teacher commitment in private vocational high schools (SMKS) in Bina Widya District, Pekanbaru. Altruism and self-efficacy are critical because they respectively reflect teachers’ prosocial orientation and confidence to perform instructional tasks—both are expected to support sustained professional commitment. Using an ex-post facto quantitative design, data were collected by questionnaire from a cluster sample of 121 teachers drawn from four SMKS (population = 174). Instruments were pretested (N = 30) and analyzed with SPSS 25 using descriptive statistics and multiple regression (F, t, R²). Results show that altruism and self-efficacy jointly have a positive and significant effect on teacher commitment (F = 53.560, p < .001), explaining 47.6% of variance (R² = .476). Individually, altruism (β = .433, p < .001) and self-efficacy (β = .263, p = .004) also significantly predict commitment. The findings suggest that promoting prosocial values and strengthening teachers’ efficacy beliefs can enhance their professional commitment. Implications for school leaders and policymakers are discussed.

Existing studies show that learning using problem-based learning teaching modules can significantly improve mathematical literacy in class VII students at SMPN 1 Kampar. A quasi-experimental design was used, with the research population consisting of VII-grade students of SMPN 01 Kampar. The research sample consisted of two classes: VII-B, the control class, and VII-A, the experimental class. The data analysis technique employed was a posttest analysis of the results from the mathematical literacy test, using the t-test to determine whether there was an increase in performance, as indicated by N-Gain data. The results of data analysis showed that the Independent Sample t-test obtained a significance value of 0.001, which means that there is a significant difference between the control class and the experimental class. The average value of N-Gain was 0.6722 for the experimental class, categorized as medium, and 0.2970 for the control class, also categorized as medium. Indicates that learning using the PBL model increases mathematical literacy higher than classes that do not use the PBL model. These findings reveal that there is an increase in mathematical literacy, thus indicating that the use of the PBL model helps improve mathematical literacy.

This research was motivated by the low ability of students to understand mathematical concepts, particularly in the topic of trigonometric ratios. The CORE model was chosen because it encourages active student participation in constructing concepts through systematic stages. The purpose of this study is to develop a valid and practical CORE-based worksheet on trigonometric ratios to support students' conceptual understanding. The development process followed the 4-D model (define, design, development, disseminate). Research data consisted of qualitative input from validators and students, as well as quantitative data from questionnaire scores. Data collection was conducted through interviews and questionnaires using validation sheets and student response instruments. The sample was selected through purposive sampling: 6 students from class XE.1 (Small Group) and 30 students from class XE.3 (Field Test). A worksheet is considered valid and practical if it achieves its values. The results showed that the developed worksheet was very valid (94.31%) based on appearance, content, and construction aspects. It was also very practical, with scores of 97.36% for Small Group and 90.13% for Field Test, assessed based on presentation, ease of use, readability, and time. CORE based worksheets encourage students to actively construct concepts actively actively, thereby facilitating their ability to conceptual understand trigonometric ratios.

This study was motivated by the importance of numeracy as a core competency required to face 21st-century challenges. However, results of the Minimum Competency Assessment (AKM) reveal that more than half of vocational high school (SMK) students in Indonesia fall below the minimum proficiency level in numeracy. This condition occurs due to the limited availability of practice items for students and the limited ability of teachers to develop AKM-based questions. The aim of this study was to develop valid and reliable AKM-oriented numeracy items to support students’ numeracy improvement. The development model employed was development studies, consisting of two stages: the preliminary stage (analysis and design) and the formative evaluation stage. The research was conducted at SMK Abdurrab Pekanbaru using test and interview methods for data collection. During the formative evaluation stage, the developed items were tested on 32 students to assess validity, reliability, difficulty level, and discriminating power. The results showed that 18 test items were valid, comprising 2 multiple-choice, 4 true/false, 3 matching, and 9 essay items. Reliability testing using the KR-20 formula for objective items produced a coefficient of 0.847 (very high), while Cronbach’s Alpha for essay items was 0.873 (very high). Difficulty analysis indicated 3 easy, 14 moderate, and 1 difficult item. Discrimination analysis showed that 15 items had good discriminating power and 3 had moderate levels. In conclusion, the 18 developed items were considered suitable for measuring and improving students’ numeracy skills and can serve as a reference for teachers in designing AKM-based assessments.

The Merdeka Curriculum changes the curriculum structure in schools, starting with driving schools as pioneers who adopt and implement P5. The principal selection process for drive schools involves several stages, highlighting the crucial principals' role in implementing P5. Not all schools will be ready to implement this curriculum, especially non-driving schools. This research aims to describe school principal policies, strategies, influence, and supporting and inhibiting factors in implementing P5 and uses a qualitative approach. Data are obtained through observation, interviews with school principals, teachers, students, and documentation. The research results show that school principals’ policies consist of planning, implementation, and evaluation. Planning involves forming a curriculum acceleration team, preparing KOSP, budgeting, and increasing teacher competency. Implementation involves forming a facilitator team, creating P5 modules, and mentoring. The evaluation highlights the improvements in school readiness, teacher assessment, and P5's orientation towards strengthening character rather than products. The P5 strategy includes understanding, preparing the ecosystem, design, management, processing assessment reports, evaluation, and follow-up. Influential aspects at SDN 032 include competent human resources and strategic location, as supporting factors for P5, while the obstacle is the teacher's slow adaptation to curriculum changes. The research results are expected to contribute to improving the P5 implementation in schools.
