Abstract

Peluncuran Kurikulum Merdeka di Indonesia telah menandai perubahan penting dalam sektor pendidikan, khususnya bagi para guru matematika di Kabupaten Timor Tengah Utara. Tantangan baru dan peluang untuk pengembangan profesional ini menuntut pemahaman yang lebih mendalam tentang kurikulum dan adaptasi metode pengajaran yang sesuai. Untuk mendukung transisi ini, sebuah program pelatihan khusus telah dirancang, bertujuan untuk memperdalam pemahaman guru tentang berbagai aspek Kurikulum Merdeka dan meningkatkan keterampilan praktis mereka dalam penerapannya. Melalui diskusi interaktif dan tugas-tugas kreatif, fokus pelatihan diberikan pada pengembangan Alur Tujuan Pembelajaran (ATP) dan modul pembelajaran yang inovatif, mendorong pendekatan pengajaran yang lebih efektif dan kreatif. Hasilnya, terlihat peningkatan signifikan dalam kemampuan guru untuk menerapkan strategi dan metode yang diajarkan, menciptakan lingkungan pembelajaran yang lebih dinamis dan menarik. Kemajuan ini tidak hanya memperkuat keterampilan pedagogis guru tetapi juga meningkatkan kualitas pengalaman belajar siswa, memberikan dampak positif pada pengajaran matematika secara umum.

Abstract

Berdasarkan tes yang dilakukan oleh peneliti pada siswa kelas XII di sebuah SMA di Yogyakarta, terdapat beberapa masalah terkait program linear, yaitu (1) siswa kesulitan dalam memodelkan masalah matematika ke dalam fungsi kendala dan objektif, (2) siswa terlalu terpaku dengan langkah pengerjaan yang diberikan guru, (3) siswa mengalami keputusasaan karena masalah program linear seringkali berupa kalimat panjang yang membuat siswa kebingungan. Penelitian ini bertujuan untuk mengetahui level kemampuan memodelkan siswa yang dilihat dari tes hasil belajar. Subjek penelitian adalah 31 siswa kelas XI IPS 1 di sebuah SMA di Yogyakarta. Data penelitian berupa hasil tes. Data tersebut diklasifikasi berdasarkan jawaban-jawaban yang sejenis lalu dianalisis berdasarkan indikator kemampuan memodelkan. Hasil penelitian menunjukkan bahwa dalam menyelesaikan soal tes nomor 1, 70,96% siswa berada pada level situasional, 22,58% siswa berada pada level referensial, dan 6,45% siswa berada pada level formal.Dalam menyelesaikan soal tes nomor 2, 93,59% siswa berada pada level situasional dan 6,45% siswa berada pada level formal.

Abstract

Pembelajaran Science, Technology, Engineering, Arts, and Mathematics (STEAM) merupakan pendekatan terintegrasi dalam pendidikan yang bertujuan untuk meningkatkan kemampuan berpikir kritis, pemecahan masalah, dan kreativitas siswa. Pendekatan ini menjadi lebih relevan ketika dikombinasikan dengan pembelajaran berbasis proyek dan kajian masalah yang berakar pada kearifan lokal, memungkinkan siswa untuk menghubungkan konsep-konsep ilmiah dengan konteks kehidupan nyata di lingkungan mereka. Untuk mendukung inovasi pembelajaran ini, sebuah program pelatihan khusus telah dirancang dengan tujuan memperdalam pemahaman guru mengenai pembelajaran STEAM melalui pendekatan proyek, meningkatkan keterampilan praktis dalam penerapannya, serta mengintegrasikan kajian masalah berbasis kearifan lokal. Melalui diskusi interaktif, tugas proyek kreatif, dan fokus pelatihan pada integrasi STEAM dengan kearifan lokal, program ini mendorong kolaborasi dan kreativitas di kalangan guru. Hasil pengabdian menunjukkan peningkatan signifikan dalam kemampuan guru untuk menerapkan STEAM dalam pembelajaran serta merancang proyek yang relevan dengan kearifan lokal, menciptakan lingkungan belajar yang kolaboratif dan menarik. Kemajuan ini tidak hanya meningkatkan motivasi guru dan kemampuan mereka dalam menyelesaikan masalah secara kreatif, tetapi juga meningkatkan kualitas pengalaman belajar siswa serta memberikan dampak positif pada pembelajaran matematika secara umum. Dengan integrasi STEAM dan kearifan lokal, pembelajaran menjadi lebih kontekstual, menarik, dan bermakna bagi siswa, mendukung perkembangan pendidikan yang lebih holistik dan kontekstual di Indonesia.

Abstract

This research aimed to describe the history of Ramayana Ballet Prambanan performances, the performance of the second half of the AnomanObong scene, the philosophical meaning and characteristics of the second half of AnomanObong, the training of dancers of the second half of AnomanObong, and the fundamental activity of mathematics in the second half of AnomanObong. This qualitative research examined ethnomathematics in the cultural context of Ramayana Ballet Prambanan. Data were collected through observation, interviews, and documentation, with validation through experts and triangulation of sources and techniques. Data analysis included data reduction, presentation, and conclusion drawing. The results showed five mathematical activities in the history of Ramayana Ballet Prambanan, namely counting, locating, measuring, playing, and explaining. There are five mathematical activities in the second half performance of AnomanObong, namely: counting, locating, measuring, designing, and explaining. There existed four mathematical activities in the philosophical meaning of the second act of AnomanObong, namely counting, locating, designing, and explaining. The counting, locating, and measuring activities were present in all data classes and can be used for learning mathematics in the domains of numbers, algebra, geometry, and measurement. The designing activity was only present in the second, third, and fourth data classes, and can be applied in math learning.

Abstract

The aim of this paper is to describe the views of mathematics teachers in Indonesia on the distance learning barriers during the early Covid-19 pandemic. Specifically, this paper investigates the barriers that teachers view as significant in distance learning and efforts taken to overcome the barriers during the early Covid-19 pandemic. This study employed a descriptive research design involving 415 mathematics teachers by snowball sampling to fill out an online questionnaire. This study shows that barriers related to pedagogical dimensions were perceived as significant in distance learning during the early Covid-19 pandemic. Moreover, this study reveals that most of the teachers did some efforts that can be done by the teachers themselves to overcome the barriers. Based on the findings, we argue that it is important to support teachers’ pedagogical competencies to conduct distance learning in order to face this current pandemic or any future crises that may potentially disrupt face-to-face learning.

Abstract

One of the abilities that students need to build when learning mathematics is problem solving ability, so that students can implement their mathematical knowledge. From the results of student tests in the previous year and exploring the problem, researchers found that the problem solving ability of students faced for Trigonometry material is analyzing problems, organizing ideas and solving problems. The purpose of this study is to describe how students' problem solving skills after experiencing learning with the Realistic Mathematics Education Approach (PMR) for Trigonometric Comparison material assisted by Geogebra. The research subjects were 31 grade X students in one of the private high schools in Bekasi city in 2024/2025. The data collection methods used were field notes, written tests, and interviews. The instrument validation technique used expert validation techniques, while to validate the data, triangulation techniques were used. The research results from the written test are as follows: (a) the most difficulties found for problems 1 and 2 were executing the plan to get a solution, and looking back at the solution process; (b) the most difficulties found for problem 3 were making a plan, executing the plan, and looking back at the solution process. From the interviews with five students, it was found that the most experienced difficulties were making a plan, carrying out the plan, and reviewing the solution process; (b) the most experienced difficulties for problem 3 were making a plan, carrying out the plan, and reviewing the solution process
