“…Sitohang et al, (2020) dalam penelitiannya mengatakan bahwa kemampuan berpikir kreatif matematis siswa menjadi lebih baik pada topik teorema Pythagoras setelah menggunakan model pembelajaran kontekstual dikarenakan pembelajaran kontekstual membantu guru mengaitkan konten mata pelajaran dalam situasi dunia nyata dan mengajak siswa menciptakan hubungan antara pengetahuan dan aplikasinya di kehidupan sehari-hari serta membantu siswa untuk dapat menyerap pemahaman konsep teorema Pythagoras menjadi lebih baik karena memiliki pengalaman belajar terkait lingkungannya sendiri. Matematika adalah sarana untuk menemukan hubungan suatu pola, mengembangkan kreativitas, dan meningkatkan kesadaran budaya (Nugroho & Riyanto, 2019).…”

This study links the concept of Pythagoras to Banten culture. Banten culture has ethnomathematical elements, especially the Pythagorean concept. The concept of Pythagoras in Banten culture includes the construction of buildings or sizes that have Pythagorean rules. The search for mathematical order in Banten culture can be a study that can be integrated into the learning of mathematics in the material of the Pythagorean Theorem. The purpose of this study explores Banten culture, namely the roof of the baduy traditional house, batik leuit cikadu pandeglang motif, banten arch, kasunyatan mosque arch, baduy totopong, baduy weaving thread, and the roof of the great mosque of Banten against the Pythagorean concept. Research methods use ethnographic approaches by integrating theoretical and empirical studies derived from observation and interview activities as data gathering tools. The results showed that Banten culture has various Pythagorean concepts, namely the concept of the Pythagorean theorem in the right triangle, the Pythagorean theorem, determine the type of triangle based on the known side, the Pythagorean triple, the ratio of the sides on the equilateral right triangle. The ratio of the sides of the right triangle with angles of 30°, 60°, and 90°. With ethnomathematical study of Banten culture as a form of strengthening character education on nationalist values by having the competence of love attitudes towards their own culture can grow and be owned by students as the identity of the nation.

Abstrak. Perangkat pembelajaran dirancang untuk memberikan arah pada pelaksanaan pembelajaran guna mencapai tujuan yang diharapkan. Penelitian ini bertujuan menghasilkan perangkat pembelajaran matematika berbasis discovery learning berorientasi pada kemampuan berpikir kritis pada materi analitik lingkaran yang memiliki kualitas valid, praktis, dan efektif. Penelitian ini merupakan penelitian pengembangan dengan menggunakan model ADDIE. Perangkat pembelajaran matematika yang dikembangkan berupa RPP dan LKPD. Instrumen yang digunakan dalam penelitian ini yaitu lembar penilaian perangkat pembelajaran, lembar observasi keterlaksanaan pembelajaran, dan tes kemampuan berpikir kritis. Perangkat pembelajaran diimplementasikan di SMA Negeri 1 Tempel dengan subjek penelitian peserta didik kelas XI MIPA 2. Penelitian ini menghasilkan RPP dan LKPD berbasis discovery learning berorientasi pada kemampuan berpikir kritis. RPP memenuhi kriteria valid dengan skor rata-rata 4,94 dari skor maksimal 5,00. LKPD memenuhi kriteria valid dengan skor rata-rata 4,67 berdasarkan aspek materi dan skor rata-rata 4 berdasarkan aspek media dari skor maksimal 5,00. Perangkat pembelajaran memenuhi kriteria praktis dengan skor rata-rata 4,4 untuk angket respon peserta didik dari skor maksimal 5,00 dan presentase keterlaksanaan pembelajaran sebesar 100%. Perangkat pembelajaran memenuhi kriteria efektif berdasarkan persentase ketuntasan tes kemampuan berpikir kritis sebesar 65% dan hasil uji t satu sampel.Kata Kunci: Berpikir Kritis, Discovery Learning, Perangkat Pembelajaran.

“…, 4) Believe that you are able to withstand obstacles and difficulties, and 5) Believe that you can complete tasks that have a wide or narrow (specific) range. Self-efficacy can be said to be a matter of subjective perception of each individual, because it is related to belief and emotional control to achieve success in facing obstacles (Nugroho & Riyanto, 2019). Katz (2009) states that disposition is a conscious, regular, and voluntary tendency to behave in a certain way that leads to the achievement of certain goals.…”

This study aims to 1) determine student self-efficacy; 2) Knowing the mathematical disposition of students; and 3) Knowing the effect of self-efficacy on students' mathematical dispositions. The research method uses quantitative methods with a one-shot case study research design. The study population was all students of the Mathematics Tadris Department of IAIN Syekh Nurjati Cirebon in the even semester of the 2020/2021 academic year with the sample being all fourth semester students of the Mathematics Tadris Department of IAIN Sheikh Nurjati Cirebon, namely four classes totaling 151 students. The data collection technique used a questionnaire to determine the students' self-efficacy and mathematical disposition. The results showed that 1) the average student self-efficacy was 72.86, included in the strong category; 2) The average student's mathematical disposition is 74.42, which is included in the strong category; and 3) Self-efficacy has a significant effect on students' mathematical disposition. Self-efficacy has an effect of 68% on students' mathematical dispositions.
