Mathematical reasoning ability is one of the most important parts of mathematics learning. However, the facts show that students' mathematical reasoning ability is still low, especially in the context of the Pythagorean theorem. One attempt to facilitate this is using students' worksheets based on creative problem solving (CPS). This research aims to develop valid and practical student' worksheets. It refers to the 4D development model, which includes defining, designing, developing, and disseminating. The instruments used are validation and practicality questionnaire sheets. The results of the validity assessment of students' worksheets were very valid, with an average percentage of 95,07%. The results of the practicality assessment of students' worksheets were very practical, with an average rate of 89,38%. Thus, it is in accord with the valid and practical requirements, so the worksheet is usable. This research aims to make it easier for students to build knowledge independently in mathematics learning so that mathematical reasoning abilities can be facilitated. Kemampuan penalaran matematis (KPM) menjadi salah satu aspek yang terpenting dalam pembelajaran matematika, namun fakta menunjukkan KPM peserta didik masih rendah khususnya pada konten teorema Pythagoras. Salah satu upaya untuk memfasilitasi masalah tersebut dengan menggunakan Lembar kerja peserta didik (LEMBAR KERJA SISWA) berbasis Creative Problem Solving (CPS). Tujuan penelitian ini adalah mengembangkan LEMBAR KERJA SISWA yang valid dan praktis. Penelitian pengembangan ini mengacu pada model pengembangan 4D yang meliputi define, design, develop, dan disseminate. Instrumen yang digunakan adalah angket validasi dan angket praktikalitas. Hasil analisis data angket validasi diperoleh bahwa LEMBAR KERJA SISWA dikategorikan sangat valid dengan persentase rata-rata yaitu 95,07%. Hasil analisis data angket praktikalitas diperoleh bahwa LEMBAR KERJA SISWA dikategorikan sangat praktis dengan persentase rata-rata yaitu 89,38%. Maka, LEMBAR KERJA SISWA pada penelitian ini telah memenuhi syarat valid dan praktis sehingga dapat digunakan dalam kegiatan pembelajaran. Implikasi dari penelitian ini adalah untuk mempermudah peserta didik dalam membangun pengetahuan secara mandiri pada pembelajaran matematika sehingga kemampuan penalaran matematis dapat terfasilitasi.

The fact that students' mathematical representation abilities are still relatively low is an issue that continues to this day in the education sector. One of the factors that influence this issue is the lack of evaluation and habituation of students in solving mathematical problems that facilitate mathematical representation abilities. Good instruments certainly need to support these evaluation and habituation efforts. This research aims to produce an instrument for assessing students' mathematical representation abilities that meets criteria that are valid, reliable, have a good discriminatory item value, and good level of difficulty. This development research uses the Borg and Gall development model, which is carried out up to the main fields testing stage. From the research results, a set of instruments for assessing representational ability in Three - Dimensional topic which amounted to 15 questions, with 8 questions in Question Package 1 and 7 questions in Question Package 2, which met the criteria for validity, reliability, and have a good discriminatory item value with a good level of difficulty too. The instrument for assessing students' mathematical representation abilities was developed from these results and met with good final results.

This study aims to describe the mathematical connection ability of first-semester students at the beginning of the trigonometry course. The research subjects were first-semester students of the Mathematics Education Study Program in the 2024/2025 academic year. The research method used was descriptive with a mixed-method approach, combining both quantitative and qualitative data. The research procedure consisted of three stages: (1) development of research instruments, (2) administration of a mathematical connection ability test, and (3) analysis of student responses. The instrument used was a trigonometry test that included indicators of mathematical connection ability. The results show that at the beginning of the course, students' mathematical connection abilities were still relatively low. The percentage of students in the very good category was only 0.83%, good category 10%, fair category 40.83%, poor category 45.84%, and very poor category 2.5%. Further analysis revealed that students in the high category were able to connect mathematical concepts and apply them to real-world problems but struggled to relate different mathematical representations. Meanwhile, students in the low category had difficulties in all aspects of mathematical connections, including linking concepts, connecting representations, and applying mathematics to real-life situations.

AbstractThis research aims to develop instructional materials for teaching statistics using a contextual teaching and learning strategy. The goal is to enhance the mathematical connection abilities of eighth-grade junior high school students. The materials are designed to meet the criteria of validity and practicality. The present study involves the development of a 4-D model, encompassing the stages of Define, Design, Develop, and Disseminate. The validation process was carried out by involving three experts. Data pertaining to the feasibility of the teaching materials were acquired through testing conducted on eighth-grade students in a junior high school. The present study examines the validation outcomes of teaching materials, which were categorised as highly valid. Based on the findings of the readability assessment, it was determined that the average score for the "easy to understand" category was 86.97%. In addition, the practicality test meets the "very practical" category. These findings indicate that the use of a contextual approach in statistics material effectively improves students' mathematical connection abilities. This technique proves to be legitimate, easily comprehensible, and particularly beneficial for promoting the development of mathematical connections among eighth-grade junior high school students.

AbstractMathematical literacy is a crucial skill, yet many students still struggle with solving contextual problems due to limited supporting materials such as student worksheets (LKPD). This study is a research and development (R&D) study employing the 4D model (Define, Design, Develop, and Disseminate) aimed at producing a student worksheet based on Contextual Teaching and Learning (CTL) that is both valid and practical. The developed content focuses on systems of linear equations in two variables. The worksheet was validated by three mathematics education experts, tested through a one-to-one evaluation with three students, and a small group test with 22 eighth-grade students from a public junior high school in Riau Province. Validation results showed the worksheet to be highly valid in terms of content, construct, CTL approach, and mathematical literacy. The practicality test indicated that the worksheet was practical in terms of appearance, presentation, and usefulness. It can be concluded that the developed worksheet is both valid and practical. Further research is suggested to examine its effectiveness and adaptability to other topics or grade levels. AbstrakKemampuan literasi matematis penting dimiliki siswa, namun masih banyak yang mengalami kesulitan dalam menyelesaikan masalah kontekstual karena keterbatasan LKPD yang mendukung. Penelitian ini merupakan penelitian pengembangan (R&D) dengan model 4D (Define, Design, Develop, Disseminate) yang bertujuan menghasilkan LKPD berbasis Contextual Teaching and Learning (CTL). Materi yang dikembangkan berfokus pada sistem persamaan linear dua variabel. LKPD divalidasi oleh tiga dosen pendidikan matematika, diuji melalui one-to-one evaluation dengan tiga siswa, serta small group testdengan 22 siswa kelas VIII dari salah satu SMP Negeri di Provinsi Riau. Hasil validasi menunjukkan LKPD sangat valid dari segi isi, konstruksi, pendekatan CTL, dan literasi matematis. Uji kepraktisan menunjukkan LKPD tergolong praktis dari aspek tampilan, penyajian, dan manfaat. Dengan demikian, LKPD yang dikembangkan dinyatakan valid dan praktis. Penelitian selanjutnya disarankan untuk menguji efektivitas serta mengadaptasikan LKPD ini pada topik atau jenjang yang berbeda.
