Abstract

Education is an important aspect indeveloping quality personnel resources to make the country's life intelligent. Mathematics plays a significant role in knowledge, as stated in Article 37 of Law No. 20 of 2003, which mandates mathematics as a compulsory subject across all education levels. However, current mathematics instruction is still dominated by conventional, teacher-centered models. These methods monotonous and lack active student interaction. Consequently, classroom environments become less engaging, hinder creativity, and fail To fulfill the requirements of 21st-century education, which emphasizes active learning processes. This issue was observed in Grade XI at SMAN 1 Batang Kapas. Students are passive due to teacher dominance.This phenomenon inspired a classroom action research study to carry out the cooperative learning model, Numbered Heads Together (NHT). This model aims to upgrade students' active engagementand learning outcomes, particularly in function composition topics. The study was conducted in two cycles involving Grade XI F.1 students at SMAN 1 Batang Kapas during the 2024/2025 academic year. The results show that the NHT model effectively improved student learning outcomes. This is demonstrated by the average test scores increasing from 82 in Cycle I to 92 in Cycle II, and classical thoroughness rising from 59% in Cycle I to 91% in Cycle II.Keywords– Mathematics, Learning Outcomes, Direct Instruction, Cooperative Learning, NHT

Abstract

Penemuan William Oughtred berupa alat peraga yang disebut slide rule membuat matematika terus berkembang. Slide rule membantu para ilmuwan dan teknisi dalam melakukan perhitungan matematika kompleks, serta membuka jalan perkembangan teknologi baru. Tujuan penelitian untuk memotivasi, memberikan informasi, dan mengetahui pengetahuan mahasiswa calon guru mengenai matematikawan Oughtred dan penemuannya. Penelitian berjenis kualitatif dengan metode literature review dan studi kasus. Literatur review didapatkan dari beberapa jurnal yang berhubungan. Teknik pengumpulan data dilakukan dengan menelaah, menganalisis, dan mengelompokkan sehingga diperoleh kesimpulan. Studi kasus didapat dari wawancara terhadap subjek penelitian, yaitu 10 mahasiswa prodi pendidikan matematika. Instrumen berbentuk wawancara terbuka. Setiap mahasiswa diberikan pertanyaan mengenai pengetahuan tentang William Oughtred dan penemuannya. Analisis data dilakukan dengan meta analisis dan analisis tematik. Hasil penelitian menunjukan terdapat tiga kategori respon mahasiswa pendidikan matematika terhadap topik wawancara. Kategori tersebut yaitu Know History Oughtred, Forget History Oughtred, dan Indifferent to History Oughtred. William Oughtred's invention in the form of a teaching aid called the slide rule made mathematics continue to develop. Slide rules help scientists and technicians perform complex mathematical calculations and pave the way for new technological developments. The research aims to motivate, provide information, and find out the knowledge of prospective teacher students about the mathematician Oughtred and his findings. Qualitative research used literature review and case study methods. Literature reviews were obtained from several related journals. Data collection techniques are carried out by examining, analyzing, and grouping conclusions obtained. Case studies were obtained from interviews with research subjects, namely 10 students in a mathematics education study program. The instrument is in the form of an open interview. Each student is given questions regarding knowledge about William Oughtred and his discoveries. Data analysis was performed by meta-analysis and thematic analysis. The results showed that there were three categories of mathematics education students' responses to the interview topic. These categories are Know History Oughtred, Forget History Oughtred, and Indifferent to History Oughtred.
