Proving ability is rarely homed in mathematics learning. Thus, this becomes interesting when examined and associate it with van Hieleâ€™s level of geometrical thinking, namely the level of deduction. This study aims to determine the thinking process of studentâ€™s level deduction in proving Triangle Proportionally Theorems and its convers. This type of research is qualitative research. Deduction level students were given a theorem proving test consist of two questions, then conducted interviews to find out more about the thinking process. The results are students level deduction can prove the theorem by utilizing the knowledge possessed both undefined terms (point and line), parallel and similarity AAA postulates, definitions of angle and congruence, parallel and similarity SAS~ theorems, corollary CSSTP and CASTC. It can be known from the studentâ€™s proving scheme and interviews that is conducted by researcher towards student.

Kecemasan geometri adalah kecemasan yang muncul ketika menghadapi hal – hal yang berhubungan dengan geometri. Tingkatan kecemasan geometri dimulai dari rendah, sedang, tinggi, dan panik. Tujuan dari penelitian ini adalah untuk mendeskripsikan kecemasan geometri siswa dalam menyelesaikan masalah bangun ruang sisi datar ditinjau dari teori van Hiele. Jenis penelitian ini yaitu penelitian deskriptif kualitatif. Subjek penelitian ini masing - masing dua siswa pada level visualisasi, analisis, dan deduksi informal. Teknik pengumpulan data dilakukan melalui kombinasi (triangulasi). Hasil penelitian ini menunjukkan bahwa siswa dari tiap level memiliki kecemasan geometri yang berbeda. Siswa visualisasi mengalami kecemasan sedang dan tinggi dalam mendefinisikan dan mengidentifikasi sifat serta unsur bangun ruang sisi datar. Siswa analisis mengalami kecemasan sedang dalam menyelesaikan masalah geometri yang berkaitan dengan perhitungan diagonal, volume, dan luas permukaan. Siswa deduksi informal mengalami kecemasan tinggi dalam menyelesaikan masalah berkaitan dengan definisi dan unsur bangun ruang serta permasalahan dalam bentuk cerita.

Penelitian ini bertujuan untuk mengetahui ada tidaknya pengaruh yang signifikan penerapan fase pembelajaran van Hiele pada bahasan sifat-sifat segiempat terhadap tingkat berpikir geometri siswa. Jenis penelitian ini adalah penelitian eksperimen. Populasi penelitian ini adalahh siswa kelas XI SMA Negeri 1 Kencong yang kemudian diambil sampel yaitu kelas XI MIPA 1 berjumlah 33 siswa sebagai kelas eksperimen dan kelas XI MIPA 2 berjumlah 33 siswa sebagai kelas kontrol. Data hasil pengerjaan Van Hiele Geometry Test (VHGT) diambil sebagai pretest dan posttest yang kemudian dianalisis dengan menggunakan uji-t melalui bantuan software SPSS. Hasil penelitian menunjukkan bahwa terdapat perbedaan yang signifikan antara kelompok siswa yang mengikuti pembelajaran dengan penerapan teori van Hiele dibandingkan dengan kelompok siswa yang mengikuti pembelajaran dengan metode konvensional (thitung = 2,067 > ttabel = 1,997). Hal tersebut diperkuat dengan hasil analisis terhadap level berpikir geometri siswa yang menunjukkan bahwa 48,48% siswa pada kelas eksperimen mengalami peningkatan level berpikir geometri, sedangkan pada kelas kontrol hanya 18,18% yang mengalami peningkatan level berpikir geometri. Berdasarkan hasil penelitian ini, dapat disimpulkan bahwa fase-fase pembelajaran van Hiele dapat diterapkan sebagai alternatif metode pembelajaran geometri di dalam kelas yang secara signifikan berpengaruhh terhadap tingkat berpikir geometri siswa.

Higher Order Thinking Skills (HOTS) is an ability that can create students in critical and creative individuals. The ways that can be used to reveal students' high-level thinking skills by using contextual problems in learning. The purpose of this study was to describe the profile of high order thinking of 8th-grade students in solving contextual problems regarding slerek boat. This research is a type of descriptive research with a qualitative approach. The research subjects were 8thH grade students of SMPN 1 Muncar, which amounted to 28 students. Data retrieval using test questions and interview activities. From the results of data collection, the results show that the ability of 8thH grade students tends to be able to solve questions at the evaluation level. This can be seen from the results of the test questions where there is 1 student who can solve the question of creation level (C6), 22 students can solve the question of the level of evaluation (C5) and 5 students can solve the level of analysis (C4). Based on the results of interviews, students who can solve the question level C5 have good ability in analyzing problems can explain the settlement process both orally and in writing, besides that it’s also able to make a hypothesis and test the hypothesis made previously

Mathematics is very closely related to the habits that exist in society. The habits that exist in society can be called a culture. The concept or aspect of mathematics related to culture is called ethnomathematics. Ethnomathematics can also be used as teaching materials that can attract students' interest in mathematics, because students will find it easier to learn science that is directly related to real life. Thus, ethnomathematics is very important in mathematics learning activities so students can learn between mathematics and culture, and know the cultural activities that exist in the surrounding community. In this study, the ethnomathematics of the tumpeng and the Tumpeng Sewu Banyuwangi ritual, which is one of the cultures in Indonesia, will be described as well as utilizing the results of their research into ethnomathematic Students’ Worksheets (LKS). Ethnomathematics obtained are activities of counting, counting, and measuring, as well as some mathematical concepts such as algebra, arithmetic, and geometry.
