Abstract

Matematika tidak hanya hadir dalam ruang kelas, tetapi juga melekat dalam kehidupan sehari-hari masyarakat melalui aktivitas budaya, salah satunya dalam seni tari. Pendekatan etnomatematika menjadi cara untuk mengungkap keberadaan konsep-konsep matematika yang tersembunyi dalam praktik budaya lokal. Salah satu wujud konkret dari integrasi antara budaya dan matematika dapat ditemukan dalam Tari Lukat, sebuah karya seni kontemporer yang terinspirasi dari ritual tradisional Seblang Olehsari di Banyuwangi. Penelitian ini bertujuan untuk mengetahui etnomatematika pada Tari Lukat karya komunitas seni Damar Art Banyuwangi. Jenis penelitian ini adalah penelitian kualitatif dengan pendekatan etnografi. Metode pengumpulan data yang digunakan adalah observasi, wawancara, dan dokumentasi.  Data yang diperoleh dianalisis melalui tahap reduksi, penyajian data, dan penarikan kesimpulan, sementara keabsahan datanya diuji menggunakan teknik triangulasi metode. Hasil penelitian menunjukkan bahwa terdapat konsep matematika pada Tari Lukat, yaitu bangun datar (segi lima, segitiga, persegi panjang, dan lingkaran), bangun ruang (setengah bola dan bola), bilangan ganjil, sudut lancip, sudut tumpul, sudut lurus, garis horizontal, serta transformasi geometri (refleksi). Selain sebagai struktur fungsional, bentuk-bentuk ini memiliki makna filosofis, yaitu solidaritas, kekuatan, penghormatan, syukur, kebanggaan, dan spiritual lainnya. Kata Kunci: etnomatematika, Tari Lukat

Abstract

This study aims to analyze similarity task in Indonesian junior high school mathematics textbooks from four different curricula: KTSP, the 2013 Curriculum, the Revised 2013 Curriculum, and the Merdeka Curriculum, using the praxeological organization approach within the framework of the Anthropological Theory of the Didactic (ATD). The research employed a qualitative approach using a document analysis method. The subjects of the study were similarity related problems found in junior high school mathematics textbooks published by the Indonesian government, across four different curricula. Coding techniques were used as the research instrument to gather empirical data about textbook praxeology organization structures, while the analysis instrument interpreted the didactic organization between praxis elements: types of task (T) and technique  (τ). The study identified nine types of task  (T1-T9) and nine corresponding techniques  (τ1 - τ9), which vary across curricula. A significant reduction in the number of type odf tasks was found in the Merdeka Curriculum textbook, indicating a shift in curricular focus concerning numeracy. These findings reveal that the variation in problem types and presentation approaches in textbooks is closely related to curriculum changes. This aligns with the role of textbooks as blueprints of the curriculum. Therefore, this research contributes to the development of mathematics pedagogy and provides valuable insights for teachers, textbook authors, and policymakers in designing more effective learning experiences. Keywords: organizational praxeology, similarity, textbook, curriculum, ATD

Abstract

Studi ini bertujuan untuk menelaah secara menyeluruh sejauh mana pendekatan pembelajaran PjBL mampu mendorong peningkatan kemampuan berpikir kritis mahasiswa dalam konteks matematika dapat meningkatkan kemampuan berpikir kritis matematis mahasiswa dalam mata kuliah Fungsi Variabel Kompleks, dengan memperhatikan peran Adversity Quotient (AQ) sebagai faktor pendukung. Penelitian ini mengadopsi pendekatan eksperimen dengan rancangan satu kelompok pretest-posttest, di mana satu kelas mahasiswa menjadi subjek perlakuan melalui implementasi model pembelajaran berbasis proyek (PjBL). Partisipan penelitian adalah mahasiswa semester enam dari Program Studi Pendidikan Matematika di Universitas Negeri Medan, yang dipilih secara purposive berdasarkan kriteria tertentu, dengan total sampel sebanyak 10 orang. Pengumpulan data dilakukan melalui tes kemampuan berpikir kritis matematis serta angket untuk mengukur tingkat Adversity Quotient (AQ). Hasil penelitian menunjukkan perbedaan besar antara skor pretest dan posttest, yang menunjukkan bahwa bahwa implementasi PjBL memberikan kontribusi positif terhadap peningkatan kemampuan berpikir kritis. Lebih lanjut, analisis N-Gain memperlihatkan rata-rata peningkatan sebesar 63,7%, yang berada dalam kategori cukup efektif. Temuan tambahan menunjukkan bahwa mahasiswa dengan profil AQ Climber mengalami peningkatan yang lebih menonjol dibandingkan dengan kelompok AQ Camper. Hal ini menunjukkan bahwa pembelajaran berbasis proyek berhasil tidak hanya dipengaruhi oleh modelnya semata, tetapi juga oleh ketangguhan individu dalam menghadapi hambatan pembelajaran Kata Kunci: Project Based Learning, kemampuan berpikir kritis matematis, Adversity Quotient

Abstract

This study aimed to analyze in depth the students' independent thinking ability in solving combination problems in combinatorics material. The research method used was a qualitative case study, involving 24 high school students in grade XI who were selected purposively based on the criteria of never having studied the concept of combination formally and never having faced similar problems. The research instrument consisted of specially designed combination story problems and semi-structured interview guidelines to explore students' cognitive processes. Analysis was carried out on four aspects of ability, namely: (1) the ability to state problems in other forms, (2) the ability to form a solution strategy, (3) the ability to apply strategies for solving, and (4) the ability to verify the results obtained. The results of the study stated: (1) problems were stated in the form of number symbols and diagrams, using narrative sentences, drawing circles, forming sets, and using symbols B1 to B6; (2) the solution strategies used included: counting with the help of symbols, counting directly without symbols, and counting alternately; (3) solutions were found by using a variable symbol and set approach; (4) no students verified their solution results. These findings confirmed that although the majority of students demonstrated independent thinking in problem-solving and strategy development, only a small proportion consistently implemented the strategy, and none verified the results. The implications of this research could serve as a reference for designing more effective learning strategies to develop students' independent thinking skills in mathematics, particularly in combinatorics. Keywords: Combination, Independent Thinking, Problem-Solving
