“…Menurut Syamsir (2017), PBL perlu diterapkan karena memiliki tujuan dapat mendorong siswa untuk mengembangkan keterampilan berpikir dalam memecahkan masalah. Karakteristik PBL adalah pembelajaran dimulai dengan suatu masalah (Choridah dalam (Zahira, Zulkarnain, & Yuanita, 2020). Menurut Wulandari & Surjono (2013), PBL sebagai tambahan bagi peran seorang guru yaitu dengan memberikan berbagai permasalahan nyata sehingga siswa dituntut aktif dalam memecahkan permasalahan yang dilakukan secara diskusi dalam berkelompok.…”

Penelitian ini bertujuan untuk menghasilkan perangkat pembelajaran matematika (berupa silabus, rencana pelaksanaan pembelajaran, dan lembar aktivitas siswa terkait materi sistem persamaan linier tiga variabel) berbasis problem based learning yang valid juga praktis. Penelitian menggunakan model pengembangan 4-D (Define, Design, Develop and Disseminate). Penelitian ini dilakukan di SMA N 2 Rokan IV Koto pada tahun ajaran 2020/2021. Data dikumpulkan melalui teknik kuisioner lembar angket validitas dan angket praktikalitas. Data dianalisis menggunakan statistik deskriptif berupa rata-rata dan persentase rata-rata. Berdasarkan hasil pengolahan dan analisis data, diperoleh bahwa skor rata-rata validitas silabus adalah 3,67, skor rata-rata validitas RPP adalah 3,81, dan skor hasil rata-rata validitas LAS adalah 3,79, sehingga perangkat pembelajaran matematika yang telah dikembangkan dikategorikan sangat valid. Persentase rata-rata kepraktisan LAS adalah 89,63% dengan kategori sangat praktis.

The condition of the learning equipment used by the teacher is not in accordance with the demands of the 2013 curriculum. Learning activities and Student Worksheets (LKPD) used in the learning process have not been able to facilitate the improvement of students' Mathematical Communication Ability (KKM). Teachers have not designed learning tools that can encourage student activities to facilitate the improvement of KKM. This study aims to produce learning tools based on the Discovery Learning model to facilitate the improvement of the KKM of students that are valid and practical. This development research uses the ADDIE development model with the stages of Analysis, Design, Development, Implementation, and Evaluation. The products produced from this research on the development of learning tools are syllabus, lesson plans, LKPD and KKM questions. The results of the validation test for the syllabus, RPP, LKPD and KKM questions obtained consecutively a percentage of 92.19%, 93.37%, 93.14% and 94.64% with very valid categories. The practicality test results got a percentage of 84.52% for small group trials and 94.00% for teacher responses in the very practical category. The results of the validation and practicality test state that mathematics learning tools based on the Discovery Learning model can facilitate students' Mathematical Communication Ability.

The student learning activities do not support developing mathematical problem solving abilities. One of the factors is the learning tools used have not provided the opportunity for students to hone their mathematical problem solving skills. This study aims to produce a valid and practical semester VIII class SMP mathematics learning device for use by using the Problem Based Learning Model with a scientific approach to the SPLDV material. This type of research is a development research with the ADDIE development model which includes the following steps: (1) analysis, (2) design, (3) development, (4) implementation, (5) evaluation. Data were collected through observation, interviews, and student response questionnaires. The subjects of this study were students of class VIII MTS GUPPI Bandar Sungai. Data analysis techniques used qualitative and quantitative statistics. Based on the results of data analysis, information was obtained that the learning device met the valid and practical criteria. The results of the validity of the learning tools in the form of a syllabus with a percentage of 82.99%, RPP 85.75% and LKPD of 83.23% fulfilled the validity level, namely valid. The results of the practicality of the learning tools seen from the student response questionnaire were 92%, these results met the practicality level, which was very practical, while in terms of the teacher's observation sheet it fulfilled the practicality level of 87.78% fulfilling the very practical level.
